A number of the sequences I've edited have a minute but noticible up-and-down movement. For example, see http://www.youtube.com/watch?v=hely09sD6gY You'll notice that only the video image moves up and down, not any of the still images or the StudioCrasher watermark. I initially thought it was the source video I'd imported, but on a more recent project I've noticed that it also does it with footage from a secondary video camera.
I also note that this doesn't happen on the original source video in Premiere, just in the edit playback and in the exported video. So, it has to be something in Premiere.
I've tried everything, including searching endless discussion boards, but I can't come up with a solution or a work-around.
Any ideas?
