My case:

the videoclips I use were created through Openshot (from a MTS video of my camera) with the profile:
Vimeo HD --> 720p 25 frames --> high quality (I think it generates mp4 x264 files?)

I have this problem in a very intense way when I use any one of these
videoclips and try to generate a new video clip by going to the "speed"
tab and make the video play backwards (reverse).

Then at the beginning of the new exported video I get black and white frames.
So it is from Vimeo HD to Vimeo HD export.

Title:
  White video output on some mpeg files

Status in OpenShot Video Editor:
  Confirmed

Bug description:
  Some mpeg files display a white screen after they have been cut with the razor tool. This issue was originally reported on the forum as white output when the video is muted, however I have found that just cutting a clip is enough to display the white output.

Steps to reproduce:

1. Drop the attached mpeg file on to the time line.
2. Cut the file into 3 roughly equal portions.
3. Set to play - when the playhead reaches the 2nd clip the video output is white.

The only other mpeg file I had (from a different source) wasn't affected by this, but it was only 11 seconds long, so not sure if it is related to length or some other property of the file.

Reproduced on bzr version 181, Jaunty 32 bit, MLT version 0.4.4 (from TJ's old repository).
