Title: Video in Sony Vegas flickers and is full of black frames

ThreadText: # Video in Sony Vegas flickers and is full of black frames
  
  (Asked by: username_0 on 2015-05-24)
  
  I'm trying to import some clips into a `Vegas 13` project, but they "flicker": some frames are all black (even in the preview), even though the files play perfectly in `mplayer` and `VLC`.
  
  The clips are recorded from a videogame using `fraps`, and then reencoded in H.264 with `mencoder` with the settings: `-x264encopts preset=slow:keyint=200:crf=19:level_idc=31:colormatrix=bt709` (I don't have the originals anymore, I deleted them to gain disk space. Stupid mistake, I know).

  While I wasn't able to fix the problem, I was able to go around it, by converting my input file into `xvid`.
  
  I don't have any black frames anymore, but the video freezes for a few seconds at some point.
  
  Since I was recording and playing the game on the same PC, I'm guessing that there's been a problem at some point and `fraps` had to drop the framerate.
  
  In any case, I suspect some other bug in my video editing setup, since `Vegas` was adding black frames in other parts of the video, that play fine once converted to `xvid`.
