I have a bit of trouble editing the Xvid MPEG-4 AVIs from my Flip Mino. Transitions between clips occasionally flash out-of-order frames.
Most often this takes place when I've dragged two source clips to the timeline, trimmed them [by dragging the edges], then slid one to overlap the other. The clips will fade in/out as expected [in the Vegas Preview Window], except for a 'flash' or two. These 'flashes' are simply momentary blips of one clip or the other by itself at full opacity. Normally the frame that 'flashes' is out of sequence. I can even use the keyboard arrow keys to step through frame by frame till I reach the 'flash' frame and stop on it. These 'flashes' DO appear in the final output render.
My work-around for now is to use GearShift to render full-length proxy clips from a media bin that contains all the source clips used on the timeline. I use a custom Cineform codec proxy preset I created just for this. Rendering the project from the new Cineform source clips yields a clean render.
I guess these are artifacts of the Xvid compression (b-frames, etc.). If anybody has info to the contrary, or a better solution, please let me know.
Thanks!
