Hi all. @ deanareeno. Yes I was using quicktime player! But the output also shows up weird on VLC and WMC too. I'm guessing I'm not using the codec right :(
After a lot of experimenting, the problem seems really random. Usually the first few times after restarting, the conversion seems to be fine. After that it's almost always screwed up. I tried lots of standard resolution 720p, 800x600, 320x160, the problem seems to show up on all of them. Except 1920x1080... really weird. But I had an idea on my way home that maybe Maya's compression isn't playing nice with ffmpeg. I'll try playblast to image sequence tomorrow and see what happens.
