 Magic Lantern **does not contain any Canon code**. Also, **we do not distribute any copyrighted code or cryptographic secrets**, neither from Canon nor from any other third party. All the knowledge used for development was obtained by analyzing ARM code, by experimenting, and from lawfully obtained documentation.

 Sorry, nothing ML can do about it. It's 576p for all cams.
+Remark: In case you are wondering about "576p" and high-res options in subscribtion based "Pro" version: 720p and 1080p are in fact just upscaled by software algorithms.

 On some cams you will find an additional entry "Crop mode" in Movie tab. Despite sharing the name those modes are not identical.
+===== How to do Open Gate recording with ML? =====
+You can not!\\
+Open Gate means\\
+- Using the whole sensor area\\
+**AND**\\
+- Using every pixel in it (as in photo mode without resolution loss by binning/skipping pixels)\\
+**WITH**\\
+- Reasonable frame rate (24 fps and up)\\
+Even for an 18 MPixel sensor it would require around 270 Megabyte/s bandwidth which is twice the fastest ML-cam can do. And there are other technical reasons restricting usage of Open Gate within ML supported cams.
+You may ask why there are people talking about Open Gate with ML if it is impossible? Answer: We don't know. Maybe they use their own definition of "Open Gate".
