I just rendered a project and I noticed a flash right before almost every transition. I went back to the Vegas project and went frame by frame over the areas that showed this corruption.
What I found was that the first frame of the transition between two events was a complete frame of the next event(the remaining frames of the transition were ok). By moving the transition one frame to the left or right I could eliminate this corrupted frame.
Anyone else encounter this issue? Are there any known workarounds?
It seems to happen if the clips are on a odd frame boundary.
