I have a .mov file I shot with my iPhone 4S to start playing with Mocha tracking. I imported the clip to After Effects and created a new composition out of it. It plays just fine in AE. Then I went to Animation -> Track in Mocha and then mocha window came up. I'm just getting a solid white video for all of the frames. I ran mediainfo on the file and got the below output, which I'm hoping is helpful in telling me what I'm doing wrong. When the mocha window came up I told it the frame rate was 29.97, and I left everything else at the default.
