When you export a video (File/Export video), one black frame is systematically added at the end of the exported video.

Steps to reproduce:
- import a video file
- place it on the timeline
- cut a slice of it by using the razor tool or whatever it is called. So you end up with 3 clips on the timeline
- remove the first and last clip and keep only the center clip. This is to make 100% sure the footage doesn't have a black frame
- place the only remaining clip at the very beginning of the timeline
- export video

Result: the exported video has a few extra black frames at the end.

This is absolutely critical (not to mention annoying)
