Yeah, I noticed that, it sort of jumps up and down a little, I don't know what the hell that is, it could be some encoding error. It could be the same thing that's causing the wall flicker. The encoding didn't go quite smoothly and the computer froze when encoding sound, so there may be a few encoding glitches in it. I might actually do another encode with a few fixes - it is a workprint for me too, you know - I can't see it play smoothly in fullscreen until I encode it either.

Ok cool , i wasn't really sure if it was a error or was meant to be in the original theatrical version
