I see this was posted in 2006 but I’m having the same problems with AE CS5
I recently made a map animation a la Indiana Jones and when I rendered it out in best quality AVI possible, there were two frames that were partially black.
I’ve had this happen before actually, usually it’s not black but like TV snow. Just a few frames in an otherwise perfect render.
If anyone knows how to solve this, I’d very much appreciate it.
