Hi guys!
I have shot about 20 takes (25 seconds each) couple days ago with my Canon 5D Mark III. RAW recording with mlv_rec works just fine. Sometimes it needs to make couple attempts first (about 100-120 frames each) with "skipping frame" warning and stopping recording (I don't really know why it so). But usually after that I can get good recording with "Continuous OK" and how can see it fills only the half of the recording buffer on 1080p 25fps. I have Lexar Professional 1000 128 Gb CF. You can see one of the shot here:
You can check the picture quality. I mean, color and dynamic range. They are really great.
But sometimes I have got such kind of picture (3 of 20 this time):
And I was terribly frustrating of it because I can never know what kind of picture I finally get because while recording all seemed to be good. And worst of all, I do not understand what causes do it. I thought it was sensor overheating at first. Then I get some good shots with 50C and dismissed this suggestion. Guys, any ideas?
UPD1: The Solution to fix Black MLV video is here

(Add --black-fix=2048 to mlv_dump string)
But the question is: How to avoid this at all?
