Canon EOS M now shoots RAW video (with the updated firmware 2.02)

I have installed Magic Lantern in my EOS M, with version 2.02 firmware. I can shoot RAW clips at 30fps, resolution 720P, aspect ratio 2:35, continuously with no time limit. I shot a 1 GB clip with no problem, at 35 megabytes (not megabits) per second. The EOS M has a relatively large buffer, and a UHS-1 card writer slot which makes it pretty good for RAW video shooting. Of course all of the key other features of ML work: zebras, focus peaking, live histogram, HDMI live monitoring, higher bitrates in AVC modes (I have tested AVC up through an average of 64 Mbs, up from an average of 42 Mbps without ML).
 
My first video from RAW

This is one sequence shot in RAW mode with the EOS M. Then, the single RAW file (one take) was split into its 800 frames as 800 sequentially numbered .DNG files. The .DNG files were read into Adobe Lightroom, where white balance was set (I chose the daylight setting). I also lowered ev by one third and then all 800 files were outputted as .Tif files. The set of 800 Tiff files (really frames) were read into Sony Vegas Pro and then rendered out as an MP4 file with a bitrate of 40Mbps at 29.970. The original frame rate was 29.970, shot at 720p in 2:35 aspect ratio (1280x544) - and that is what you see. The sequence bitrate in the camera was about 35 megabytes per second and continuous shooting (I could have shot until the file size limit). The original RAW file was almost 1 Gigabyte for this 25-second sequence shot in extremely bright sun
 
Are you using the full sensor, or is this with the 1:1 mode that uses only a central crop?
 
mmm... not that useful really, if you ask me

what's the horizontal resolution using the full sensor? and how many lines can you capture at 24p?
 
Horizontal resolution at 24p for stable unlimited shooting in crop mode is 1728. I understand crop mode is necessary, but there is still development going on.
 
1728 makes sense: that's 5184/3
if the camera can do 1728x720 with the full sensor, continuously, at 24p, without dropped frames or anything like that, that would pick my interest

Same here. Crop mode doesn't interest me.
 
Looking a bit more into it, I think there's no hope of useful full sensor RAW recording on any of the cameras recording to SD.

If all the SD card controller can do is 40 MB/s, then max resolution at 24p with full sensor would be 1728x578, which has a very wide 3:1 aspect ratio.
For 2.40:1 ratio (the 1728x720 I was talking about), you'd need 50MB/s.
For 16:9 (1728x972), it would be 68 MB/s.

This chart is old given how fast ML evolves, but I'd guess that the card max write speeds haven't changed.

I think those high resolution modes are just "until the buffer is full", so maybe 30 or 40 frames. I haven't payed much attention to recent developments, though.

I didn't realize I could do 5 second clips at 1728x972 (full sensor) with the 60D. That's awesome! It's definitely a severe limitation, but long enough per clip it could be workable for a short film.

Have you tried that and have any tests? My 60D is for sale but if I can get this resolution it may be worth hanging on to a while longer.
 
Here is a FULL 720P (1280 x 720) video from RAW using the EOS M, at 24fps. Yes, using crop mode:
