I'm working with uncompressed avi files in AE. I'm having a very frustrating issue, and I want to see if there was any kind of setting within AE that I could tweak to get my videos to look correct.
The videos look fine sometimes, but usually the video looks terrible. It appears that the frames look fine as long as there is little movement in the scene, but once the scene changes, the video frame freezes (almost as if it wasn't refreshing), then as the scene changes the video "wipes" itself clean again, and then the video returns to normal.
Windows Media player and VLC both view the videos completely perfectly, however, AE does not!
Sorry if this is redundant, but are you certain that they are uncompressed avi's? How were they generated? Can you post a sample?
Sounds like the files are compressed in some form that doesn't store full frame info for every frame. I've seen similar results using Quicktime Animation codec files, where the files used interval keyframes rather than storing every frame as an independent frame.
Try converting the file to a true uncompressed format (or to Quicktime Animation with keyframes set to "All") before importing to AE.
