HAve you checked the key frames on that clip
What happens if you cut out that last frame? Is all well, or does the new 'last frame' show the same odd behavior?
Yes Jim. If I cut out a frame, the new last frame does the same thing.

Next try this. Add a black clip on a video track above the problem clip. Cover only the last frame of the video clip with black. Does it go from normal to black, or do you still see weirdness before black?
