  In order of preference,
  
  * Generate animation at 25 FPS and capture it at 25 FPS.
  * Generate animation at 50 FPS and capture it at 50 FPS. Then, use FFmpeg to generate a 25 frames & 50 fields per sec stream. Stream should be flagged as interlaced. x264 doesn't do interlaced well, so I suggest video codec ought to be MPEG-2 or DV.
