Sure:
1. Load MLV record module
2. Enable in Movie preferences
3. Press record.
I can confirm this for 960 and 1152 resolutions on the 600D.
80% of the time I wind up with at least 3 pink frames (vs. 0% with raw_rec. Same shoot, same day, usually just seconds apart from each other.)
It's pretty consistent. Only 20% of my shots don't have pink frames. They're usually just in the beginning of the clip... but could be anywhere. Version used was this: magiclantern-Nightly.2014Mar26.600D102
