The text was transferred from https://www.magiclantern.fm/forum/index.php?topic=11269 and is by no means up to date or complete. Many sections just duplicate the text that is displayed in the footer of the camera display anyway. This needs to be enhanced of course. Please mention known incompatibilities, caveats etc.
Please anyone: Login to the wiki with the same credentials as for the magic lantern forum and add or correct wherever you see something missing or outdated.
As a first step it would be already helpful to mark outdated sections by editing the section and add a comment like that:
which would show as

Don't be afraid of making mistakes. It is far more important to provide content since fixing mistakes is much easier than writing help texts.
For the time being restrict the formatting to simple text with only basic formatting like headlines, bold or italic text, bulleted or numbered lists, since it will be converted to ReStructured Text in time to be used on the camera display. For that the text will be split into separate files on level 2 section headings (f.e. ===== Audio =====), so please restrict your headings to levels 3 to 5.

Update (18.02.2019) Walter Schulz
Listings (= menu items) should be complete and up-to-date by now. If not: Report back!
Task for all readers: Check for errors, misconceptions, blank fields, unhelpful items (overcomplicated or just missing help). Think of everything you can imagine an in-camera help should include!
Special task: HDR section! If you have experience with HDR workflow, preferable with Open-Source tools (but not restricted to), any input would be appreciated!
Update (25.02.2019) Walter Schulz
Updated “Focus” section.
Missing: Proper help for Focus Settings/stepping.
Don't think I will describe the full FRSP+Expo.Override/Sticky DOF+Focus stacking workflow here. More suited for a tutorial IMO.
Updated Auto exposure a bit. EC parts still missing.
HDR section untouched. Task still valid, copying from above
Special task: HDR section! If you have experience with HDR workflow, preferable with Open-Source tools (but not restricted to), any input would be appreciated!
Complete (18.02.2019). No pics for plugs, etc. here, because it's in-camera help and drawings for soldering doesn't help that much in this respect, IMO.
And if Audio screen isn't visible this help text won't be able to tell users why. That's one reason I opted for this screen to be visible at all times.
Manual audio controls.
If you do not see this screen check these conditions:
The options available differ a lot depending on your camera type.
Please check feature matrix
Gain applied to both inputs in the analog domain.
Analog does a great job of boosting the signal while retaining a low noise floor and hence, dynamic range. If you use an external preamp, set this parameter as low as possible otherwise, set it as high as possible without clipping (audio meters should be green).
In-camera digital gain.
Left Digital Gain 0 to 36 dB in 6 dB increments
Right Digital Gain 0 to 36 dB in 6 dB increments
AGC ON or OFF
Applying digital gain in-camera is not recommended as any non-zero value reduces audio quality and you can achieve the same effect with more control in post, but it can serve as an evaluative tool on set. You can apply digital gain in 6dB increments to the left and right channel independently. AGC is auto mode and is applied only in digital domain. It overrides digital gains, but you can still adjust analog gain.
Internal mic your camera's internal mic(s)
L:int R:balanced (internal mic on Left, external mic on Right from both external pins as balanced audio)
Auto int/ext camera detects if a mic is plugged in. Int is dual mono, ext is stereo.
Balanced audio allows for very long cable runs without interference. Usually balanced mics have three pin XLR connectors and it is very easy to put together an XLR to Canon mic input cable. Balanced allows us to use such pro mics with our little Canons and this is a very welcome surprise for audio guys. You can feed an external audio source into the camera giving you the option of using higher quality mics, although this is not straight forward.
Digital high-pass filter.
On or Off
Canon's audio controls have no effect, they are completely overriden by ML and the wind filter has been known to mute external mics, so if you're having that problem on an earlier build turn it off. To use or not? Also see AK4646 datasheet p.34.
Power for mics.
ON input impedance is 2 kOhm.
OFF input impedance is 30 kOhm.
Required for internal mic and certain types of external mics, but it reduces input impedance. This setting is always ON when input source is either internal mic or L:int R:ext. See AK4646 datasheet p.31. and the Mic power control thread. Results of audio tests with ML and Canon 550D, T2i.
Audio monitoring with headphones, using the A/V cable.
On or Off
To use audio monitoring, you need a special cable: your Canon A/V cable with a RCA - 3.5mm jack adapter a dedicated cable from Sescom or you may solder it yourself (you will have to cut your A/V cable). Mobile phone cables will not work; even if the connector looks similar, it's not identical. You must use the original cable which came with your camera. For details, see Audio monitoring HOWTO on Vimeo group. Disable this setting if you are using a SD monitor. This feature is not available on 600D/T3i.
Tip: Before cuting/soldering or ordering a monitoring cable check feature matrix if this feature is available for your cam at all.
Digital output gain for audio monitoring.
It does not have any effect on the internal camera speaker. For best results, you should a pair of low impedance headphones, for example Audio Technica ATH-M50 (38 ohms). With high-impedance headphones, you may have to use a headphone amplifier like FiiO E5.
Display the input audio level.
From -40dB to 0dB, meters become yellow at -12 dB and red at -3 dB. Audio meters are only displayed in movie mode.

Customize camera sounds.
Enable Beeps ML uses beep tones for several events. Turn them off if you have to go silent.
Tone Waveform Sine tones of lower frequency might be not audible on the internal speaker. Use square. Always check with Test beep sound.
Tone Frequency Default is 1 kHz. Range from 55 Hz (A1) to 12 kHz. Human ears are considered to be most sensitive between 2 and 5 kHz.
Play test tone
Test beep sound
Sampling rate 8 - 48kHz the basic quality of your audio, the higher the better.
Trace output ON or OFF
When MLV Sound is ON, a separate WAV file is generated at the framerate determined by your FPS setting in Canon Menu. When FPS Override is used, only the framerate of raw video is affected, the WAV file will remain either 24fps or 30fps depending on the FPS setting in canon menu. It is not possible to playback mlv sound in-camera.
Adjusting the exposure parameters. Most of these settings only work in Manual (photo and video) but some work in P, Av and Tv too. For availability see feature matrix Some items will only be shown after loading the appropriate module in the Module screen:
The following settings are linked to Canon settings. If you change them here, the changes will appear in the Canon menu too and vice versa.
White balance controls.
White Balance: Rated in Kelvin, allows manual adjustments from 1500K to 15000K.
There is no “AWB” option here. If you want to use AWB you have to re-enable it in the Canon menu.
WBShift G/M: Green-Magenta white balance shift. Useful for fluorescent lighting.
WBShift B/A: Blue-Amber white balance shift. 1 unit = 5 mireks on Kelvin axis, according to this post.
Custom RGB multipliers: Fine-tune custom white balance.
Auto adjust Kelvin + G/M: In LiveView, ML will compute the white balance for the current scene using the center (200×200 pixels rectangle) as reference gray.
Preferred method is manual White Balance, but when shooting raw video this is more of evaluative tool as you have control of your WB later. Best practice is to have a reference colour at the beginning of each shot, with neutral grey being preferred to white because whites can blow out and give a false reading.
Advanced ISO control.
Equivalent ISO: Overall ISO rating.
Canon analog ISO: 100 to 3200 ISO at which the sensor is driven.
Canon digital ISO: Digital ISO is the process of pulling or pushing your analog ISO to affect detail. Requires “Exp. Override ON” (see below in Expo screen).
For best image quality, it is strongly recommended to leave this set to 0 EV.
ML digital ISO (DIGIC): -2 to +7 EV Preferred to the Canon implementation, in movie mode. Negative values will reduce noise, but may cause color issues in highlights. This feature enables ISO 25 or 50, ISO 51200 and many other intermediate or astronomical ISOs.
Fine-tune shutter speed.
1/31 - 1/3900 Without Expo.Override enabled
1/24 - 1/7900 With Expo.Override enabled
In photo mode, Magic Lantern displays shutter values rounded to 2 significant digits, so 1/48 may be displayed by ML as 1/50. This is not a bug. In movie mode, shutter values are displayed with 3 decimal places for example, in PAL mode, Canon uses 1/33.333 to avoid flicker. To use shutter speeds normally not available in Canon firmware like 1/25 or 1/8000 in movie mode, enable Expo.Override. The shutter can be locked (perfect for video) in the Movie Tweaks section of the Movie menu, meaning you have to go into the ML menus to change it.
Requiring a chipped lens, when Expo.Override is enabled, you can adjust in 1/8 stop increments.
It's one of two option for EF lenses to work stopped down with Silent Pics and the only option not blocking buttons. With “Expo. Override ON” by changing aperture here (it will not work from within Canon menu) lens blades will instantly adjust to the chosen aperture number.
Disclaimer: Issue #2929, not working with STM and other contemporary lens designs.
Change picture style or adjust its parameters.
You can use a different picture style when recording (toggled automagically). May be useful with flat picture styles. Raw video makes no use of this feature. This setting will not be shown in the Canon menu! At the beginning of recording a notification about the REC-PicStyle selected will be seen.
Automatically expose to the right. Only visible after loading ettr.mo in Modules.tab. ML needs LiveView to compute camera settings according to environment!
this wiki entry is massive! Copying it here makes little sense, IMO. Extracting basics?
Text bit copied from ettr.mo Readme
ETTR is a technique that optimizes your exposure for raw shooting, with the goal of minimizing noise without accidentally blowing the highlights.
Auto ETTR will adjust the exposure for you until the histogram will touch the right side, but - whenever possible - without clipping. This will minimize image noise for your given set of restrictions (e.g. slowest shutter, max ISO, or what highlights can be clipped).
You will usually have to darken the image in post (which is good).
Tip: on the raw histogram you will see an ETTR hint that can be used for manually exposing the image.
Trigger mode Always ON, Auto Snap, Press SET & HalfS DblClick. Method for executing Auto ETTR.
Slowest shutter 32“ to 1/4000. Set your lowest speed.
Exposure target -0.5, -1, -2, -3 & -4EV. -0.5 or -1 recommended.
Highlight ignore 0 to 50%. Percentage of bright pixels allowed above target level. Use this to allow spec(ta)cular highlights to be clipped. Example: In standard situations with the sun in frame it makes no sense to prevent the sun from being blown out because the rest of the pic will be vastly underexposed. The same for the sun reflected off polished metal and similar situations with extreme highlights.
Allow clipping OFF, Green channel & Any channel. Choose which channels to be clipped.
Midtone SNR limit 0 to 8EV. Stop underexposing when at least 50% of the image gets noisier than selected SNR.
Shadow SNR limit 0 to 6EV. Stop underexposing when at least 5% of the image gets noisier than selected SNR.
Link to Canon shutter Hack to adjust the slowest shutter from main dial.
Link to Dual ISO Let ETTR change Dual ISO settings so you get the SNR values in mids and shadows. This will disable dual ISO if it is not needed.
Show metered areas Show where the white point and SNR levels are metered (what exactly are considered highlights, midtones and shadows).
Show debug info For nerds.
See ettr.mo in Modules.
In M mode this settings lets you change Tv, Av or ISO without changing exposure.
Locks different exposure controls in M mode.
Tv You can adjust Tv as desired and ML will adjust ISO and/or Av accordingly to keep exposure constant.
Av You can adjust Av as desired and ML will adjust ISO and/or Tv accordingly to keep exposure constant.
ISO You can adjust ISO as desired and ML will adjust Tv and/or AV accordingly to keep exposure constant.
Toggles exposure presets (ISO, shutter, aperture).
OFF - disables exposure presets.
Press SET - assigns the SET button to the exposure preset function.
Press INFO - assigns the INFO button to the exposure preset function.
Usage: Press the assigned button once then adjust ISO/shutter/aperture as desired. Subsequent presses of the assigned button will toggle back and forth between the original and adjusted exposure settings.
Capture using 2 different ISOs in a single picture for better detail in certain ranges. Only visible after loading dual_iso.mo in Modules screen tab.
Increases dynamic range by sampling the sensor at two different ISOs, switching ISO for every other line pair. This trick cleans up shadow noise, resulting in a dynamic range improvement of around 3 stops, at the cost of reduced vertical resolution, increased aliasing and moire in the highlights and shadows.
Works for both raw photos (CR2) and raw videos (DNG). You need to postprocess these files with a tool called cr2hdr.
To do: List other postprocessing tools
After postprocessing, you will get a DNG that looks like a dark ISO 100 shot, but you can bring the exposure back up and be delighted by how little noise is present in those recovered shadows.
Tips and tricks
Recovery ISO - The secondary ISO used for recovery
Dynamic range gained - Expected increase in Dynamic range with the current recovery ISO
Midtone overlapping - The midtone area where both ISO's capture data without overexposure or excess noise.
Alternate frames only - only enable dual ISO every second frame.
Custom file prefix - changes the filename prefix to help identify dual ISO images when post-processing.
See dual_iso.mo in Modules.
This mode bypasses Canon exposure limitations for ISO, Tv & Av.
OFF: Canon default exposure mode.
ON: ML overrides exposure values (change them from Expo menu).
Auto: ML enables it only when needed.
In photo mode, anything slower than 1/25 seconds will be underexposed in LiveView. Low framerates in FPS override have fixed shutterspeeds. To compensate, exposure adjust aperture and ISO. In the daytime this is tough as even at ISO 100 with the lens closed down the image can be overexposed. For these situations, consider using a VARI-ND filter.
Enabling/disabling Exposure Simulation in LiveView
In entry level cams (xxxD/Rebel) there is no option in Canon menu to disable Exposure Simulation. Without ML it may enforce some additional steps to get exposure settings you need.
To do: EC stuff

TV minimum sets the maximum shutter value. Yes, it's a menu bug. But it's what you want avoiding motion blur in sports and other action shootings.
Same TV curve
AV range sets aperture range, if it not match with current lens, it doesn't matter, it will be compensated with shutter
AV curve by main dial you set point where will start aperture decreasing (in BV value) speed dial sets how much will be aperture decreased, it sets the slope (minus EV per one BV)
ISO range 100 - 25600 make sure that you set correct ISO range (you can set this values via Canon ISO menu), otherwise you can get incorrect exposure. It also solves the 5D2 auto ISO bug, where is ISO hardcoded to 400.

Graphics overlays that can be used in LiveView or in image review mode: histogram, zebras, cropmarks, spotmeter, focus peaking, false color…
You can create and configure up to 4 individual ML LiveView screens which may be toggled by INFO button, too. If you want to have 2, 3 or 4 go to Prefs screen → LV Display Presets and change number accordingly. To determine which screen is active: Text field shows “DISP 0” to “DISP 3” in LV. Same number will be shown in Overlay screen.
Overlays do affect processor performance. Doing high performance write operations (as in RAW/MLV movie recording) it is adviced to reduce “active” overlays or surpress them at all during recording. You will find a lot of options affecting the appearance of overlays for that reason.
Same applies to streaming and recording via HDMI. Be aware it might take some time to find a workflow and appropriate settings for your needs.
Choose when to enable Magic Lantern overlay graphics such as zebras, cropmarks, histograms, audio meters and other ML shooting info.

If you used display presets, press Q on this item to switch the presets while you are in ML menu.
Be aware there are 2 other menu options influencing Overlay visibility: - Display screen → Clear overlays - If MLV_REC module is used there is an option “Global Draw” and default is OFF! Computing overlays will reduce cam's storage interface write rate.
Enable/disable zebra stripes, which indicate overexposed or underexposed areas.
Color Space settings apply to JPG/H.264 only. RAW is not affected.
Underexposure - JPG only. Set the RGB point where underexposure zebras are displayed.
Overexposure - JPG only. Set the RGB point where overexposure zebras are displayed.
When recording - Show or hide zebras while recording.
Use RAW zebras - Enable raw based zebras. This uses the raw sensor data for zebras.
Raw zebra underexposure
This allows you to choose at what exposure the underexposure zebras will be displayed. 0 EV means that the zebras will be displayed where the amount of noise in the image, is equal to the amount of signal in the image (the noise floor). A general consensus among photographers, is that the limit for acceptable amount of noise in images, is 2 EV above this noise floor.
Dual ISO zebras: When using dual ISO, there are dual exposures and the zebras reflect this. With dual ISO there are two types of zebras.
Focus assist function.
Alpha blend will be laged.
Threshold: how many pixels are considered in focus (percentage).
Color: either fixed color, or a color coding according to focus intensity.
Grayscale image: if enabled, LiveView will displayed as grayscale, but still recorded as color.
High-contrast lines will be marked by blinking dots (or other setting from “Display type”) showing which part of the image is in focus. To see how it works, check this article from Luminous Landscape.
Displays a zoom box for focus assist. Can be used while recording.
Size Size of zoom box: Small, medium or large
Magnification 1:1, 2:1 or 3:1
Focus confirm When ML believes you have achieved perfect focus, Magic Zoom will display a focus confirmation:
Zebras, focus peaking and false color are disabled automatically when the zoom overlay is active. Focus triggering only works with lenses that report Focus distance, or when you use follow focus / rack focus. In some modes, half-pressing the shutter may temporarily hide the zoom overlay.

If you use custom cropmarks, place them in ML/CROPMKS folder on your SD card and give them names following 8.3 naming convention. Example: MyCrop01.bmp. You can place at most 9 cropmarks on the card. Get more cropmarks from the ML cropmark repository or draw your own. http://magiclantern.wikia.com/wiki/Cropmarks
Be aware about cropmarks not scaling when switching to “Crop mode” and/or changing aspect ratio! Grids activated by “Grid display” in Canon menu will interfere with ML's cropmarks. It's recommended not to use both at the same time.
Shows a transparent overlay which can be created from any image in Play mode.
To select the image, go to Play mode and press the LiveView button. Move the ghost image in LiveView with arrow keys; center or hide it with SET or joystick press.
Measure brightness from a small spot in the frame.
This is a tool for evaluating the exposure.
Banding detection Enables fast check if there are under- or overexposed areas. Everything else is greyed out.
GreenScreen Enables fast check if green screen conditions (uniform lighting) are met.
It shows different luma (Y) levels using a color map. You may configure a display preset with False Color and toggle it with a single button press. You may also use false colors to highlight 50% and 70% brightness levels, or to reveal color banding, or to check for uniform green screen lighting.
This exposure tool will show the distribution of image brightness levels in a histogram.

Functions specific to movie mode.
Controls H.264 bitrate used for video recording.
CBR factor 0.1x to 3.0x.
QScale -16 to 16.
Bitrate Info ON or OFF.
BuffWarnLevel 30 to 100.
In CBR mode, QScale will not go outside [-16…+16]. When QScale reaches the extreme values (-16 or +16), bitrate will be different than your CBR setting. Watch the bitrate indicators. This is not a bug, please do not report it. You can push the bitrate higher if you record without sound, then use Audio RemoteShot to sync the video with an external audio track. You can't change this setting during recording. If buffer usage gets too high, ML will pause all CPU-intensive graphics. Change the BuffWarnLevel setting to customize this.
Enable movie recording on 50D (1920×1080, 30fps, without sound). To start recording, go to LiveView (P/Tv/Av/M) and press SET. WARNING: Canon 50D was NOT designed to record movies. Keep in mind: This feature was not thoroughly tested by Canon and may be unstable (even if you record without ML). Always disable movie recording when you don't use it. Battery will drain quickly when recording; also, the camera may overheat.
Limitations: The camera will not record sound. You can use an external recorder (for example, Zoom H1, H2 or H4n) and sync the sound in post with a clapperboard. You can't play back movies in the camera. This setting remains active even if you start the camera with standard firmware (until you clear your settings).
Block during REC blocks the shutter and related (AF, *) buttons while recording. In 50D, taking pictures while recording would result in ERR99; with this option, you can avoid taking pictures while recording by mistake. Side effect: this will disable image stabilization during recording.
Hold during REC (IS) ML will keep the shutter button pressed half-way during recording, which will enable image stabilization (IS). Side effect: you need to press the shutter button half way to turn IS off before the camera will let you stop recording.
This option enables you to start/stop movie recording by half-pressing the shutter button.
Require long press
With this, you can use a wired remote to start/stop recording.

This setting alters FPS for all video modes.
Desired FPS 0.150 fps to 65 fps depending on your model capabilities. If the desired value is not possible, ML will choose the closest safe option (see 'Actual FPS' below).
Optimize for Presets that will suit different situations:
Shutter range displays the available shutter speed range with current settings. When you use FPS override, Canon menu will still display 1/30 to 1/4000, but the actual shutter speed will be found on ML displays. You can alter shutter speed range by changing the ratio between the two timer values - decreasing timer B will result in faster shutter speeds available.
FPS Timer A FPS is changed by altering two timer values. Increasing either of these values results in lower FPS, faster shutter speed and alters rolling shutter. Only undercranking works well. Timer A gets you in the ballpark and ML will re-adjust timer B to match your FPS choice.
FPS Timer B ML will not re-adjust timer A, so this option will let you fine-tune the exact FPS value.
Main Clock displays the crystal oscillator frequency of the FPS circuit driver (read-only, depends on your camera).
Actual FPS this displays the current FPS, computed as TG_FREQ / timerA / timerB (read-only).
This function will not change the frame rate from the video header; the video will playback at the setting from Canon menu. Set FPS to a very low value like 3fps to record a timelapse. This feature also works in photo mode, making LiveView usable in dark environments. Combine it with display gain. To get 180-degree shutter speed at very low FPS, simply discard half of the frames in post. If 0.2 FPS is not enough, use Frame Merger (a VirtualDub plugin). Exact frame rate may be rounded to be an exact multiple of PAL/NTSC frame rates.

Time indicator When recording a movie, ML will display a small time counter in the upper right corner, which can be:
Unlike Canon's timer which assumes constant bitrate, ML timer assumes variable bitrate and works even if QScale is enabled. However, due to variations in bitrate, the estimated value will fluctuate a lot, and this is normal.
Movie Logging If this setting is ON, Magic Lantern will write out a metadata file for the each movie to MVI_1234.LOG (numbered after the movie). The log file contains lens and exposure info, as well as a timestamp every time any of the parameters is changed during recording. Log files are placed in the same folder as the movies: DCIM/100CANON/, 101CANON etc. Tip: you can rename LOG files to CSV and import them in MS Excel.
Movie Restart While this setting is on, movie recording will restart automatically, unless you stop it. There will be a few frames (typ. about 0.5 seconds) skipped during restarting.
H.264 (native Canon MOV recording): Older Canon cams (Digic 4, no ExFAT support) do have 2 limits: 29:59 minutes recording time or recording reaching 4 GB. Whatever comes first will cause recording to stop. Newer cams (Digic 5, ExFAT support) will stop at 29:59 minutes only.
MLV/RAW recording (Magic Lantern only): No limit at all. Record as long as you like and battery, card space and temperature are good to go. You may want to use this option to restart recordings stopped due to buffer overflow (card too slow to manage data bandwidth) but there will be corrupted frames. Buffer overruns will coming back after a short period.
If you want to do external recording or streaming (HDMI, USB) for 30+ minutes you do not have to use this setting anymore. Requires an experimental build (lua_fix or 4k).
REC/STBY notify Custom notifications for recording or standby:
All options with display output require Global Draw/Overlays activated.
Force LiveView bypass the dialog saying Press LV button to activate movie shooting.
Shutter Lock This option locks the shutter value in movie mode (you will be able to change it only from ML menu).
Locks the exposure in movie mode. You can also use the * button (you don't have to hold it pressed).
Functions for stills shooting, some of them work for movies too.
Exposure bracketing for HDR images and timelapses. Aperture bracketing for landscapes, etc.
Bracket type Choose the variables to bracket.
Frames Number of bracketed shots. Can be computed automatically.
EV increment Exposure difference between two frames.
Sequence Bracketing sequence order / type. Zero is always first (cannot be changened in code, don't ask for it).
2- second delay Delay before starting the exposure.
ISO shifting Also use ISO as bracket variable. Range 100 - max AutoISO.
Aperture bracketing In M mode, this function does shutter and/or ISO bracketing. In the other modes it does exposure compensation bracketing. To start bracketing, take only the first picture and ML will continue the sequence. To preview HDR images in camera, set SET+MainDial: ExposureFusion from Prefs menu, Image review settings, then go to playback mode, hold SET and turn the main dial (wheel). For each HDR picture set, Magic Lantern may also write a bash script for stacking the exposures with enfuse (version 4.x), with optional alignment (align_image_stack). More info: Exposure Fusion: What is it? How does it Compare to HDR? How Do I Do It?
Exposure time > 30 seconds: Not a problem at all. ML will extend exposure time on its own = entering ML's bulb mode. Screen will use setting stored in Bulb Timer → Display during exposure (see below in section Bulb Timer).
Exposure time below cam's shortest shutter time: You will see an “E” appended to the lowest duration time. Means: Cam's limits are reached, this is an error. All photos set for lower durations will be taken with cam's fastest shutter timing.
Take pictures at fixed intervals. Additional features available after loading “Advanced Intervalometer (adv_int)” module.
Take a pic every Duration between two shots. More precise: Time between 2 “shutter button actuations”. If duration is set to lowest setting (0s/like crazy) cam will take pics in burst mode. Caveats: If selected interval is lower than exposure time next pic will be taken immediately after last pic. Option “Long exp. noise reduction” will result in exposure time doubled if condition is met. If Intervalometer is used to trigger “Full Resolution Silent Pic” camera will take a few seconds for processing FRSP. Don't expect “like crazy” (burst mode) to run without hickups. Cam has to wait for free buffer to continue shooting. Same may be happen with low duration settings in combination with high date rates (RAW) and/or cards with low write rate.
Internal note: ML menu shows (bottom line) calculation for time lapse duration depending on number of pics and interval. No idea how to represent this.
Start trigger Options for how to trigger intervalometer.
Start after Start delay (up to 8 hours).
Stop after Stop after X pictures.
You can stop the intervalometer by rotating the mode dial, by pressing MENU or PLAY, or by turning off the camera. To avoid aperture flicker, shoot in manual mode, use manual white balance, avoid short exposure times and use a manual lens (if you use an EF lens, lock the aperture and unscrew it). To make a timelapse without increasing shutter count, do not use the intervalometer; instead, set FPS override to a very low value (for example, 3fps) and start recording. Or use Silent Pic mode Full Resolution Silent Pic. When using the intervalometer in LiveView with noisy mode, your shutter will wear twice as fast than outside LiveView. If the intervalometer can't be stopped (it may happen in crazy mode), turn the camera off or open the card door. Adjust your auto-off setting to longer than your timelapse interval the camera will turn off before the second shot. When not in LiveView, press DISP or INFO to turn the display off. In LiveView, ML will turn the display and the sensor off during idle times if you enable this option from Powersave menu. While the intervalometer is running, the card led will blink once per second to let you know it's alive and kicking.
Ramping options Only visible after loading module adv_int.mo
Advanced ramping and exposure control for the intervalometer Forum: http://www.magiclantern.fm/forum/index.php?topic=8431.0
Create keyframes from current camera settings and specify the frame at which the keyframe is applied. You will select which parameters you would like to set in the keyframe and which you would like to ignore. The module ramps (linearly) the vaules of selected parameters from one keyframe to the next while the intervalometer is running.
You should create an initial keyframe at 1, that has the settings you are going to start with, that way the module knows what to ramp from. If you don't do this the module won't ramp to your first keyframe, it will simply set the values when it gets there (it doesn't know how to calculate the ramp, b/c it doesn't know what the values started as).
To ramp basic expo controls (Av, Tv, ISO) set them like normal in the canon GUI as if you were taking a picture, then go into the ML menu under 'Shoot' → 'Intervalometer' → 'Ramping Options' → 'New Keyframe' and create a new keyframe. Turn on or off to specify which parameters are to be included in the keyframe. The current values are displayed on the right for you, but you cannot change them from here.
For Focus you do specify the offset to focus to from the 'New Keyframe' menu. The module will calculate the number of focus steps it need to take each frame to arrive at your offset that you specify. It steps from wherever the lens is focused at the start. Negative values mean focus closer, positve is towards infinity. You need to be in LiveView for the focusing to work and make sure there is enough time after the exposure is taken, before the next one starts for the focusing to take place (I recommend at least 2s, maybe more depending on camera and lens)
You can ramp the intervalometer period as well, this you also specify from within the new keyframe menu Once you have created keyframes you can view them with the 'List Keyframes' menu. You can also save your keyframe sequence to file, and then reload them later. If not saved, any keyframes you created will be lost when the camera is turned off. Keyframes are saved and loaded from a file called “SEQ.TXT” in the ML/SETTINGS directory. When you have created keyframes and are ready to begin, make sure the advanced intervalometer is turned on, then turn the intervalometer on as usual from the ML Shoot menu.
This module is compatible with AutoETTR so long as you don't try to ramp the parameters that AutoETTR is trying to change. You can ramp Av and let AutoETTR take care of Tv and ISO, or you can ramp Av and Tv and let AuttoETTR only set ISO, or put AutoETTR to link to Canon shutter (then your Tv will basically be setting the slowest Tv parameter of AutoETTR)
Menu item only visible after loading module “Post Deflicker (deflick.mo)
De-flickering stills, time-lapses and movies to achieve matching brightness. May be used to get flicker free time-lapse.
Sidecar file type Sidecar file format for deflicker metadata.
Deflicker percentile Where to meter for deflickering. Recommended 50%.
Deflicker target level Desired exposure level for processed pics. 0 = overexposed.
File naming for sidecar files expects setting “Color Space = sRGB” and does not support “Adobe RGB” setting on its own. If used for silent pics: Supports DNG files only!
Very long exposures with Bulb mode and ML timer. This feature is useful for night shots and astrophotography.
Exposure duration from 1s to 8h00m00s in 1 seconds increments.
Display during exposure
Bulb timer is started by holding the shutter pressed halfway for one second, or by remote triggers / intervalometer. You can cancel the exposure earlier by half-pressing the shutter button. If used together with other features (Silent pics, Intervalometer, …) make sure half-shutter actuation will not get mixed up.
Start/stop remote shutter release mode with the LCD sensor.
Near: To take a picture, put your hand near the LCD sensor.
Away: Picture is taken when you get your hand away from the sensor. You may combine this setting with Mirror Lockup.
Wave: Picture is taken after you wave your hand 3 times near the sensor. You can leave it on without interfering (too much) with normal shooting.
This feature is useful for avoiding camera shake. In Movie mode, the Wave ? setting is able to start and stop recording movies. The other modes can only start recording (because it's too easy to stop recording by mistake). While recording, the Near and Away modes can trigger the rack focus operation.
Start/stop remote audio trigger.
Trigger level (dB)
To take a picture (or start recording a movie), make some loud noise, for example, clap your hands or pop a balloon. With the audio trigger you can sync a video recorded without sound with an external audio track. This may trigger the shutter from the sounds made by camera (like focus beep or noise from operating the buttons).
This setting is not persistent! If cam is turned off or going into powersave Audio Remote Shot will be disabled. If you want to use this feature for surveillance you may want to use LUA script to enable Audio Remote Shot after brownouts.
moving subjects which cause significant change in exposure.
(luma channel only); this detects smaller movements which do not change exposure.
Trigger level High values = less sensitivity to motion.
Detect Size Size of the area on which motion shall be detected.
Delay Range from 0 (OFF) to 1 second in 0.1 second increments. Delay between the motion detection and picture taken.
Detection time is somewhere between 200-300ms (according to DataGhost's speed test), or faster with silent pictures. If “Use Autofocus” is selected it may add another (non-deterministic) delay due to the focusing.
This setting is not persistent! If camera is turned off or going into powersave Motion Detection will be OFF! If you want to use this feature for surveillance you may want to use LUA script to enable Motion Detection after brownouts.
Take pictures in LiveView mode without moving mirror or shutter. Only visible after loading silent.mo in Modules screen tab.
All options (excluding “Full-res” which does use full sensor area and resolution) work similiar in respect to resolution/aspect ratio. Resolution/aspect ratio depends on LiveView and is therefore restricted. And actual resolution/aspect ratio depends on camera model, being in still or movie LiveView, zoomed in or not. You might want to use movie mode for highest vertical resolution. And yes: “Silent pictures” is working in Movie mode, too.
around 1 or 2 MPix, and depends on the current mode (zoom or not, recording or not, and movie resolution). For almost-FullHD resolution (1720×974), choose FullHD to record a dummy movie.
Limits: FRSP is not made for short exposures. You will get overexposured pictures if you insist on using short shutter settings. If you use minumum exposure time (1/4000 or 1/8000) you will get a gradient. (Example: 5D3 gets 1/33.19 at the frame's top and 1/6.30 at the bottom). 500D, 550D and 600D are limited to exposure times up to 0.8 seconds. Other cams can do 15 seconds. Tips: You have to enable Expo Override to change aperture. Or use manual lenses. ETTR works best with Intervalometer. Set ETTR option “Always On”. Adjust aperture or use ND filter to get exposure times above 0.5 seconds. Otherwise results may be impossible to deflicker in postprocessing. Don't forget Silent pic and Intervalometer are using the same default trigger. Change Intervalometer trigger to “Leave menu” to avoid this.

File Format Choose DNG or MLV. Later requires loading MLV_REC.mo. In short: “DNG” writes a single pic to a single files. MLV writes all single pics of a session into a single MLV. Similiar to a movie file consisting of several consecutive frames. A new session (incrementing file name) begins after powersave or after shutdown/restart. If you want to use Deflicker option (deflick.mo) you have to use DNG format. MLV not supported.
Storing into MLV is considerable faster than writing DNG. Example: 7D, burst mode (94 pics). Writing DNG: 80 seconds Writing to MLV: 24 seconds
Silent picture setting is applied to intervalometer and remote triggers.
Description neeeds work: It will also go to LiveView when you press the shutter half-way.
Therefore, you should only enable this setting when you actually use it.
File names (DNG): File naming for silent pics is derived from the last “normal” picture taken. Canon names RAW files IMG_xxxx.CR2 (colour space setting sRGB) or _MG_xxxx.CR2 (colour space setting aRGB). Silent DNG pics will be named xxxxyyyy.dng beginning with yyyy=0000. Number will be incremented with each silent pic written to card. Keep in mind option “Best Focus” does write files not in chronological order but in order of focus precision.
If Silent Pics are triggered by Intervalometer name schema changes to Intervalometer settings: Counting beginns with 00000000.DNG on an empty card (=no previous intervalometer session stored) or continues counting from the last intervalometer shot.
File names (MLV): File naming for silent pics is derived from the last “normal” picture taken. Canon names RAW files IMG_xxxx.CR2 (colour space setting sRGB) or _MG_xxxx.CR2 (colour space setting aRGB). Silent pics (MLV) of a session will be stored in xxxxyyyy.MLV beginning with yyyy=0000 for the first session. In “Simple” mode a new session begins after Powersave or Shutdown/restart. In “Burst” modes each burst will generate a new session file with file number incrementing.
Mirror lockup. See Canon user guide for details.
MLU mode Choose when MLU should be active.
Handheld Shutter At what shutter speeds you want to use handheld MLU.
Handheld Delay Delay between mirror and shutter movement.
Normal MLU Delay MLU delay used with intervalometer, bracketing, etc.
Timer+Remote will auto-enable MLU under one of the following conditions (and disable it otherwise):
self-timer mode is on (either 2 second or 10 second, but not continuous)
LCDsensor Remote is in Away mode.
A few tweaks for flash users:
external flash without putting light on the scene coming from the onboard flash.
whether to use flash or not. Odd pictures (by file number) will be taken with flash, even pictures without flash.
Available for 1100D, 500D, 550D and 600D only. None of them here to test. Anyone out here to be able to drop a word?
disables LiveView on half-shutter press. DISABLE this option when you don't use it!!!
Pics at once Range: 1 (OFF) - 9. How many pics to take at once for each trigger event.
Useful for one-time events like Audio Remote Shot, Trap Focus, Motion Detect. If using together with Intervalometer make sure exposure time (multiplied) does not exceed interval duration.
Use Autofocus For intervalometer, audio remote shot and motion detect.
With default setting OFF intervalometer, audio remote shot and motion detect will *not* use autofocus no matter AF on lens is selected. If trigger condition is met an image will be taken! With setting ON autofocus will be used. If the cam is unable to establish focus confirmation there will be no image aquisition. Also consider that lag between trigger condition met and image aquisition will be extended by the time needed for focusing.
Post scripts Post processing scripts/listings for bracketing and focus stacking.
This option will generate a flat text file for each bracketing or focus stacking sequence. Those are made for Unix-like systems (OS X, macOS, Linux,…) able to run .sh scripts or (in case of “File list”) are just lists of image file names for given sequences. Caveat: Image file names are generated with .JPG extension regardless which image files format is actually recorded. If you want to run those scripts with RAW/DNG/MLV you may want adjust this by another script.
Intervalometer Script Scripts/list for sorting intervalometer sequences.
Those scripts consists of commands creating directories for each interval sequence and moving associated image files to those directories.
Directories names are computed according to first file name of a sequence. Example: First file is named IMG_1234.CR2 → Directory name will be IMG_1234 (without extension) and it will contain all files for that sequence.
Snap Simulation Simulates picture aquisition for testing purposes without wearing out shutter and mirror. Useful for testing Íntervalometer, Advanced Bracketing and Focus Stacking features.
Different controls for focus.
Takes a picture when the subject comes into focus.
Hold AF button you need to hold the autofocus button (half-shutter, * or AF-ON, depending on your settings).
Continuous you don't need to hold any button; ML will hold the half-shutter pressed for you. This will also block most buttons; press the shutter halfway to unlock them for two seconds.
Outside LiveView, it only works with lenses with chip. In LiveView it only works for photos, and it will take a picture when the focus indicator has (almost) maximum value on the focus graph. You may have to turn the lens back and forth a few times in order to let ML compute the correct focus scaling factor for the current scene. If you move from a high-contrast scene to a low-contrast one, you will also have to wait a bit until the high-contrast data disappears from the focus graph. Press SET to temporarily disable automatic scaling of focus magnitude.
Very simple follow focus (like a rack focus controlled manually).
Focus using OFF
Focus using Arrows you will be able to focus with the arrow keys.
Focus using LCD Sensor Focus by placing your hand near the LCD sensor (avoiding shake). To use this, you may need to disable LCDsensor Remote.
Quick rack focus while recording:
MENUto save current focus point (this means
I want to return here);
PLAYto go to saved focus point;
PLAYagain to go back.
When “Arrows” is selected you have the option to use slow (FF-, FF+) or fast (FF–, FF++) focusing.
When “LCD Sensor” is activated you only have slow focusing (FF-, FF+). You have to toggle direction by LCD sensor itself! A short wave in front of the sensor will trigger focusing one step into the “false” direction and toggle FFx.
This is end point of rack focus and focus stack (X focus steps from the start point, i.e. from current focus point).
Works in Liveview only!
How to use:
Focus the lens in Liveview1, enter ML menu by pressing trashcan button, browse to this menu item and press Q.
After pressing Q, ML will display “Focus End Point: 0 steps from here..” This means the end point is now assigned to current focus position. At this point, you will see the LiveView image (if not: Press Q again until LiveView is active. See screenshot) and set start point using left and right keys (just like with follow focus) or the main dial (scrollwheel). The start point will be always the current focus point (which you are changing); the end point will remain fixed. There may be a bit of lagging between focusing and screen info getting updated with actual focus step numbers.
1 You can use 5x/10x magnify to get better focus control
If want to get rid of ML menu items in LiveView you may press trashcan button.
Triggers the rack focus operation that moves between the start and end focus points. You have to set both points in “Focus end point” menu!
After the move is complete pressing again reverses the move.
SET: rack focus will start after 2 seconds;
Not reproducable with 650D,7. Not working Q: rack focus will start immediately;
Record start not working in 650D, 7D
Play button not working in 100D at all PLAY: ML will automatically record a short clip with the rack focus operation.
Rack Focus (and Focus Stacking) are using AF motor step settings defined in menu item “Focus Settings”!
This selection will shoot a series of photographs with varying focus points.
It is frequently used in macro photography to enlarge depth-of-field (DOF) by merging photos where each has a different focus point. Also used - to a lesser extent - in landscape photography.
Another term for this technique is DFF (Deep Focus Fusion).
Run focus stack
Num. pics in front “In front”. Direction: From “reference point” (current focus point) towards your camera.
Num. pics behind “behind”. Direction: From “reference point” (current focus point) away from your camera.
Focus steps / picture “Number * Step Size = actual steps between two pics”. In short: Adjust Step Size according to lens used and adjust “Focus steps/picture” according to magnification factor, aperture and desired details in stacked image.
Flash Delay If flash is used this setting will determine seconds reserved for recharging. Your cam is unable to know if the flash is properly charged or not.
Copy rack focus range Takes focus points selected with “Rack focus” for Focus stacking. See “Usage”, esp. “Method 1”.
Before you begin you may consider running cam in Snap Simulation (Shoot screen → Shoot Preferences). This will prevent wearing out mirror and shutter while struggling to make sense of focus stacking settings, esp. finding proper front and back focus planes and proper focus step values.
Sequences running into focus delimiter (reaching cam's focus distance limit) will get terminated with an error message “Focus: soft limit reached” and - worst case - leaving you with a bunch of files not suitable for postprocessing.
Configure rack focus and use it to preview the focus range.
Then select menu item “Copy rack focus range”. Select the number of focus steps to skip. This will determine the number of pictures to be taken.
Press PLAY to start the focus sequence (PLAY mode) or take the first picture with shutter release.
Focus your lens. This will be the reference point for this session. You may now select “Num. pics in front” and/or “Num. pics behind”. After taking pics lens will return to reference point.
Script generation: After enabling one of the options found in “Shoot” → Shoot preferences → Post scripts each session will generate a file called FST_xxxx.sh. See description for this menu item.
Focus stacking can be combined with other ML features. Enabling FRSP (Full Resolution Silent Picture) with Focus stacking will reduce wear and tear to shutter and mirror rigorously!
Focus Stacking (and Rack Focus) are using AF motor step settings defined in menu item “Focus Settings”!
If Wait is not active, ML will only wait a for fixed delay before sending next focus command. This will reduce stutter, but may affect rack focus accuracy. This setting is recommended if you only use follow focus.
If Wait is active, ML will wait until each focus command is completed, and then it will wait for a fixed delay, as configured here. This will increase rack focus accuracy, but may cause stutter with certain lenses.

Custom focus patterns which can be used either with autofocus or trap focus. Menu item will be seen in cameras with “classic” 9-point rhombus.
To change the focus pattern:
Set your camera in photo mode, non-LiveView. Look through the viewfinder and make sure the main display is off. Change the focus pattern with the arrow keys and SET. You may or may not receive visual feedback. Press the Zoom In button twice to see the current selection. You can use the custom focus patterns in LiveView Quick Focus mode, too, but the pattern won't be displayed on the screen. This feature was ported from 400plus.
Read-only lens and Depth of Field data.
Lens: Lens identifier, focal length, aperture
The distance to the focal point. Value is returned by most newer Canon lenses.
If the lens does not report any distance information, 0 will be displayed and the DOF calculations will not be correct. See also Focus distance.
The hyperfocal distance is the point of focus where everything from half that distance to infinity falls within the depth of field. This is the largest depth of field possible for the current f-number.
The nearest distance in which objects appear in focus.
The farthest distance in which objects appear in focus.

Normal (no effect)
Boost on WB adjust
Photo/stills mode only. This feature increases the brightness in LiveView, making it usable in very dark scenes (where Canon's LiveView would be pitch black).
Combine this with FPS override for better low-light performance in photo mode. For movie mode, use ML digital ISOs for a similar effect.
Clear bitmap overlays from LiveView display.
HalfShutter Hold the shutter half-pressed, or the * button, or DOF preview for around 1 second to clear all the overlays from the Live View display (audio, zebra, crops, shutter speeds…).Tip: assign autofocus to * button (from Custom Functions, set Shutter/AE lock button = AE lock/AF).
WhenIdle In this mode, all the overlays are erased from the screen (100% clean display) when the camera is idle (i.e. you don't press any buttons).
Always In this mode, all the overlays are erased from the screen; you will have to change shooting settings blindly. You can still use the menus.Tip: this feature may be useful with External Recorders, since it removes the focus box and other graphics from the display.
Be aware there are other options affecting overlay visibility: Overlay screen → Global Draw → Options: Off, LiveView only, Quickreview only, Both LV and QR. And MLV_REC has a switch to turn off Global Draw, too.
Preview the rectified (defished) image from Samyang 8mm fisheye lens, using rectilinear projection.
This feature works best in photo mode (outside LiveView). Defishing uses a pre-computed look-up table (LUT). It is possible to create LUT files for any other lens or projection by defishing vram/xy.png with your favorite defishing software, and then running vram/defish-lut.m to get the LUT file. All the required files are found in the ML source tree. Project files (*.PTO) for nona (hugin) are provided for both rectilinear and Panini projections.
Adjust display for anamorphic lenses.
Screen Layout Choose screen layout (position of ML top and bottom bars), for different cameras or for external monitors. Top/bottom layouts:
Color scheme This affects the colors and brightness of the on-screen information including LiveView overlays, Canon menus and ML menus.
Range from: Default (bright), Dark, Bright Gray, Dark Gray, Dark Red, Dark Green. Tip: dark themes may reduce the eye strain during night shooting.
Image position This may make the image better visible from different angles (especially on cameras without flip-out screen).
Range from -16px to 16px in 8px increments.
UpsideDown mode This mode is useful if you want to mount your camera upside-down.
Upside-down and mirroring option
For cams with flip-out LCD
Auto Mirroring For cameras with flip-out LCD, this options prevents mirroring the display when you open it at 180 degrees.
LV crazy colors
May be helpful for white balance.
Force HDMI-VGA This option will force a low-resolution mode on HDMI displays (720×480), which avoids black screen when you start/stop recording.
Can some 50D user verify the location of this setting?
For 50D only: disable Canon graphics elements to avoid conflicts with ML graphics in LiveView.
This menu is unique to 5D3.
Card test at startup
CF card workaround
Magic Lantern saves its settings in a configuration file named MAGIC.CFG, located under ML/SETTINGS directory on your card. This submenu lets you customize how these settings are saved.
SET at startup By enabling this ML will not be loaded at startup. Same as pressing SET during startup.
Config preset Create different presets of menu configurations.
ML options and settings can be overwhelming, esp. when trying to switch between different setups. Using Config Presets allows to switch numerous ML settings at once. Therefore presets come handy.
Tipp: Use smart naming conventions such as preceeding P or V letters to distinguish between photo and video presets. Caveat: Order of custom presets is not by alphabet/number but date of directory creation (time stamp)! Newest cames last, oldest first.
Config AutoSave Saves settings automatically to magic.cfg whenever you change a setting in ML menu. Config saving process will take place as soon as you close the menu.
Save config now Save ML settings to ML/SETTINGS/MAGIC.CFG or the config preset selected.
Restore ML defaults use this to restore ML default settings. After deleting the config file, restart the camera.
As mentioned above using Config Presets allows to switch numerous ML settings at once. If you want to rely on this feature make up your mind about how to change and preserve settings. The issue at hand is: There is no “Back to last setting”. ML has 2 options (indiviual for each config preset):
Imagine you are in the field and one of your precious config preset settings has to be changened because of unique circumstances. With Config AutoSave ON your precious preset will be overwritten and you have to remind yourself to reset this very setting if you want to go back to status before. With Config AutoSave OFF the changed setting will not be persistent and gone after shutdown. So you have to remind yourself to re-set this very setting or you are shooting with just the setting from the very beginning.
There is no right or wrong in using either option. It's just up to you to find a suitable workflow to avoid problems. Don't forget: If you are using Config Autosave OFF you are still able to overwrite your settings by using “Save config now”!
Recommended for custom presets: Backup your ML\Settings directory to a safe location. You will be able to restore settings anytime by just overwriting the troubled preset directory or all of them.
Customize the image review (playback) mode.
Play mode actions When you press associated “Trigger key(s)” (see below), ML may perform one of these functions:
Quick Zoom Faster zoom in PLAY mode, for checking critical focus:

Use SET button Enable functions for SET when you use arrow keys:
LCD Sensor Shortcuts Use the LCD face sensor as an extra key in ML (e.g. for triggering arrow keys, for blocking follow focus or for bypassing magic zoom key). To fully disable the LCD sensor in Magic Lantern, disable LCD auto off from Canon menu (Wrench 1). You need to do this if you are using a device which covers the LCD sensor (e.g. a loupe).
Sticky DOF Preview Makes the DOF preview button sticky (press to toggle). Enabling DOF preview will block certain buttons. Enable Exposure Override to preview DOF without blocking the buttons.
Sticky HalfShutter Makes the half-shutter button sticky (press to toggle). Use this to prevent the camera from turning off LiveView after 30 minutes.
Swap MENU ERASE (60D) Swaps MENU and ERASE buttons. This feature allows one-handed navigation in ML menu on 60D, but will have to use MENU button to delete the pictures.

This feature lets you create 1, 2 or 3 additional ML LiveView screens with individual Overlay presets.
This menu item sets the number of available ML LiveView screens. Default setting is OFF (1), enabling only a single ML LiveView screen. To change the current preset, press INFO/DISP in LiveView, or [Q] on the GlobalDraw entry in the Overlay menu. On the top bar, you will see DISP 0, 1, 2 or 3. Each of those is a preset for the settings in Overlay menu. So you can, for example, configure DISP 1 with false colors, DISP 2 with zebras and focus peaking, and DISP 3 with clear display.
Crop Factor Display
If enabled, ML bottom bar will display the 35mm equivalent focal length, including crop factor (1.6x).
For example, a 50mm lens at f1.8 will be displayed as:
Focus Distance Units Choose between metric and imperial measurements for focal distance.
Ready for review
Creating “MyMenu” screen for ML settings. You can select menu items of your choice.
Activate browsing by pressing SET. Bar colour will change from blue to dark orange, same colour as bottom line and tab (screen) name. Browse to the item you want to select for ML's MyMenu screen and press SET once. Green star icon shows selected items. Press SET twice to hide menu items in ML screens (x). Pressing SET a third time will deactivate selection. After selection completed go back to Prefs screen → Customize Menus and press SET again to deactivate browsing. Colours will change back to default.
All items marked for MyMenu (green star icon) will be displayed in screen MyMenu and are accessible from here, too. If you access a screen with hidden items you will see a text “Hidden:…”(in orange color) indicating what items are hidden.
MyMenu will work together with Config Presets and are configurable individually for each config preset. MyMenu settings are stored in ML\Settings (and associated config preset subdirectories). File name is MENU.CFG. If you got totally lost you may want to delete MENU.CFG to go back to default menu structure.

Modules are one of the great things about ML and they tend to just appear out of nowhere (nowhere = years of programming skills). Forum member Audionut put together a resource for compiling your own if you are upto it: creating your own modules or creating your own modules 2
Remark: LUA script language is another approach to lower the bar for creating own enhancements for ML. LUA scripting is considered to be easier to learn and develop (no compiling needed) but is restricted to things implemented in LUA API. Modules don't have this limitation.
The modules listed in this section are included in the nightly builds. For other modules see Modules (other)
For discussion: AFAIK modules tab is the only screen where help texts are included in code. And - besides activating and deactivating - additional help texts including submenu descriptions serve no purpose here. So: What are we actually doing here? Help texts and listings of submenu items are needed where the menu items are. Wrong?
No response. Cleanup in progress! Done!

Functions for troubleshooting and development. Most likely you (presumptively a non-developer) will have no reason to access this screen using ML. Exceptions:
Disable all modules
Load modules after crash
By default (OFF) ML modules will not be loaded after a crash or after battery pull during operation. Users and developers may find setting OFF helpful to identify and disable misbehaving modules in the field. For unattended cameras in remote locations setting “Load modules after crash ON” might be preferable esp. if used together with some kind of watchdog timer or otherwise intermittent power source. Same for situations under stress where having time for troubleshooting is not an option.
Card interface performance and other (more nerdy) tests.
Only visible after loading Bench.mo in Module screen.
Completed benchmark runs will save results as PPM files (Portable Pixmap) to card's root directoy. File naming will be BENCHx.PPM with consecutive numbers whenever a benchmark is taken. You can convert PPM to PNG/JPEG (using your PC )if you want to share results in ML forum (for example).

File naming will be VRAM0.PPM with consecutive numbers whenever a screenshot is taken. The PPM does not contain transparency data. You can convert PPM to PNG/JPEG if you want to illustrate your problem in a forum request.
This is a placeholder in one of ML's source files for customized/temporary debugging code. By default it is empty, doing nothing at all. If needed you (or more likely: a developer) can add code inside source which has to be compiled to a customized ML build to be executed by you.

Displays the amount of available RAM.
Displays the number of shutter actuations divided to “pics taken” + “Liveview actuations”. A liveview session will increment “Liveview actuations” by 1. Each pic taken in a liveview session will increment “pics taken” *and* “Liveview actuations”. Therefore a single still picture taken in Liveview will add 1 to “pics taken and 2 to “Liveview actuations”.
Numbers will not get updated until next startup.
Displays internal temperature, in Celsius, Fahrenheit and some Canon-specific unit called “raw” (not to be confused with image data format). ML reads cam's value for “efic_temp” which can a little bit different from value found in image's exif data.
Internal Temp will be shown in ML liveview screen, too. Celsius value only!
Displays battery percentage, estimated time remaining and battery discharging rate. For accurate readings, wait until the percentage indicator decreases by at least 2% since powering on.
Remarks: There had been several complaints about ML draining batteries. Down to this day all of these claims could either be broken down to user errors (improper card handling, activating ML features affecting powersave mode, …) or were not reproducable at all. Avoid improper camera shutdown and - most important - never remove card during shutdown or immediately after opening card door. For those who want to play it absolutely safe: Remove battery after shutdown.
ML being active does however cost some energy thus reducing battery life a bit.

Parking lot for items lost in transition
Sets the number of seconds before starting a rack focus.
This lets you film the start point first, then initialise the rack focus without touching the camera.
Recommended focus step settings: Focus StepSize: 1 or 2 Focus StepDelay: small values, without Wait flag. If the motion is not smooth, try larger delays (100ms)
Quick rack focus while recording:
Press MENU to save current focus point (this means I want to return here); Use follow focus to change focus point (focus somewhere else); Press PLAY to go to saved focus point; Press PLAY again to go back.
Explanation belongs in “Focus End Point”
Pick the end point of rack focus by focusing on it (manually or with AF). Configure focus parameters (step size and delay). Different lenses may require different parameters. Open the Focus menu, go to Focus End Point and press Set to zero it out. Pick the start point by focusing on it with the LEFT/RIGHT buttons while the Focus menu is active. Make sure the number from Focus End Point is changing as you focus. Fine-tune the position with scrollwheel. Go to Rack Focus and press SET or PLAY to start rack focus. To return to the starting point, run rack focus again. Tip: when LCDsensor Remote is set on Near or Away, you can trigger rack focus from the LCD sensor, avoiding camera shake.
Recommended focus step settings (menu item “Focus Settings”):
Step Size: 1 or 2
Step Delay: - without Wait flag: large delays (around 100 ms) ? will ignore small position errors - with Wait flag: small delays (only lens is in very good mechanical condition)
OBSOLETE Whole section is no longer represented in Shoot menu. IMO this should be replaced by a proper description for Advanced Intervalometer.
Bulb Ramping allows the capture of a timelapse that gradually changes exposure, compensating for the transition from day to night.
Auto exposure ramping: this option will adjust shutter and ISO automatically, by looking at image brightness of previous shots.
Manual exposure ramping: this option will adjust shutter and ISO to follow a fixed exposure ramp (a fixed amount of EV change per shot). Can be used as standalone or combined with auto ramping.
Manual focus ramping: this lets you adjust focus gradually while shooting the timelapse. It requires a lens with autofocus and it can only work in LiveView.
Settings for auto ramping:
Mode: sunset / sunrise / auto. In sunset mode, the exposure will always increase. In sunrise mode, the exposure will always decrease. This idea was suggested by Tom Lowe on RedUser.net forum.
Maximum ramping speed: this parameter is used for computing the optimal smoothness factor. A lower value will reduce flicker, but if the value is twice as low as the real rate of brightness change, ML will lose the ability to ramp correctly. For example, if you set a maximum ramping speed of 0.1 EV / shot, and the scene requires a ramping of 0.2 EV / shot, ML will start flickering heavily.
Quick start guide for auto ramping:
1. Take a picture of your scene. You will use it to say: I want my timelapse to be exposed like this picture.
2. Enable Bulb Ramping and Intervalometer.
3. Leave the camera still while ML runs a calibration step:
Make sure you have a static and well-lit scene (any static scene which does not require long exposure should be fine).
After calibration, you should get a nice S-curve on the screen.
4. Now you will have to say what tone range to meter for (i.e. highlights, midtones…). Follow the wizard:
Use arrow keys to select your reference picture (which you just took).
Use the main dial to select the tone range to meter for. You can't perfectly match two images just by varying one parameter (exposure), so you have to choose what's important for you in this picture.
For lowest flicker, meter for midtones (choose the 50th percentile, i.e. median, because it's a robust estimation, unlike simple averaging). Leave some headroom for highlights (underexpose a bit).
If highlights are important, meter for them (choose 80th percentile for example). You will have to shoot RAW and remove flicker when you develop the RAW files. The algorithm works best when brightness is close to 50% (try not to choose extreme values for it). When you are ready to start, press SET. 5. Sit back and relax :) Limits: ISO is chosen between 100 and maximum auto ISO value from Canon menu. Shutter speed is chosen between 1/8000 (lower limit) and the delay between two shots minus two seconds (upper limit). Example: for 10-second intervals, shutter speed will be between 1/8000 and 8 seconds. Aperture is fixed (you can change it manually). Tips: Don't adjust ISO and shutter before the timelapse, they are fully automatic. Use a ND filter to reduce flicker during daylight. Reduce flicker in post. We recommend VirtualDub with MSU Deflicker plugin (free, works with Windows and Wine). See also Timelapse workflow using free software tutorial. Technical notes:
Exposure is metered using a condition like this (for example): 70% of pixels should be below 50% brightness.
Exposure for every shot is computed from previous shots, using a feedback controller algorithm with a smoothing factor.
ISO is chosen using the 180 degree rule, so the resulting shutter speed stays between 90 and 270 degrees (that is, between 1/4 and 3/4 of the delay between two shots).
Only full-stop ISOs (100, 200, 400 etc) are used (because you are supposed to shoot RAW).
Shutter speed can be adjusted with a resolution of 10ms. Frames with fast shutter speeds (less than 1 second in Rebel cameras, less 0.1 seconds in 60D) are taken in Manual mode. You will get flicker. It can go from 1/8000s @ ISO 100 (daylight) to several minutes of exposure time @ ISO 6400 (complete darkness).
Exposure algorithm is a feedback controller designed with pole placement - the closed loop response will have two real poles placed at the smoothing factor value. Smoothing factor is computed in such a way that, when scene ramping speed matches the speed selected in menu, ramp is followed at exactly 1 EV behind it. If the lighting changes suddenly a few stops between two shots (for example, you change the ND filters or the aperture), the algorithm should recover completely after 2 or 3 shots. A sudden exposure change is considered when the exposure difference is greater than 2 stops.
Logging: When you use bulb ramping, Magic Lantern will save a log file with the exposure parameters, metered values and so on. Please send this file to developers. These log files can be used to see how well the ramping went and to fine-tune the algorithm.
This function can also create scripts named like named FST_1234.SH, which can
be used for stacking the images with enfuse. See Exposure bracketing
for details on how to use these scripts, and the focus stacking section
from Enfuse reference manual. To enable (or disable) the post-processing
scripts, go to
HDR bracketing Shoot → Shoot Preferences submenu.
You can also combine this function with HDR bracketing and silent pictures.

Silent Pics Outdated, redo here, then up again
When enabled, it saves uncompressed YUV422 frames from the LiveView image buffer when you press the shutter halfway. Make sure you don't have autofocus assigned to half-shutter press (put it on * or turn it off) Images are saved in DCIM/1xxCANON/ after the following rules:
If intervalometer is OFF, silent pics are named after last picture/movie taken without this function (e.g. 12340001.422). You are limited to 10000 silent pictures for each noisy picture.
If intervalometer is ON, silent pics have names like 12345678.422. Tip: use File Numbering ? Manual Reset from Canon menu to increase folder number (to sort them easier).
To convert a 422 image to JPEG on the PC, use one of the following programs:
422-jpg.py (command-line tool, runs on all platforms, you need to install Python, PIL and numpy).
422toimage (Windows only, source code available).
YUV422 Convertor (Windows only, closed source).
OBSOLETE? Silent Pic Hi-Res:
emulates high-resolution by taking a matrix of small silent pics, in zoom x5 mode. You need to have the camera on a tripod and the subject should be static (a picture is taken in a few seconds). Could be useful for focus stacking or for timelapse without increasing shutter count.
When enabled, it will temporarily reduce picture quality in burst mode in order to maintain a decent frame rate even when the buffer becomes almost full.
This function will reduce picture quality if the buffer has space for less than 4 pictures:
