Alright I found where I got the 720p thing.
I probably read this post or something similar to this but the idea was the same probably. To empty the buffer of the camera.
But this post is from 2013, so I guess this new crop_rec build don't require 720p/640p in Canon menu anymore.
However,
I just realized I do get pink frames every once in a while in my footage. Yesterday they weren't there, I must have broken something.
After 8 years, again I find myself in the ML rabbit hole.
Edit: I had a good footage without any problems (no pinks, no frame skips) with 640/30-canon settings and 1080p 30/46/38 @ 38fps ML setting. However, I disabled the fps override setting when I was recording this. Maybe It was ruining my earlier footage.
If your buffer fills up you'll get pink frames. To avoid it, set the resoltuion in the Canon menu to 640p @ 30 fps (Lower YUV buffer = more space for other stuff) and use 'FPS Override' to lower the framerate. Also, make sure you have a fast SD-Card that reaches the 600D's 21 Megabyte/s write speed limit and set the 'Pic Quality' to 'SRAW' (And reboot your camera!) to increase the shoot_malloc buffer size. That should help to get rid of any pink frames. If they still appear you can try to use an older build.
By following these steps I haven't got any pink frames since weeks.
