  UserWarning: x bytes wanted but 0 bytes read at frame index y (out of a total z frames), at time q sec. Using the last valid frame instead - Wiz Newest 'ffmpeg' Questions - Stack Overflow
  I have a script which subclips a larger video and then stitches needed parts together using concatenate and write video file in moviepy. But the problem is everytime i run the script i get the video but the audio is off sync, usually the audio starts normally, but over time becomes delayed.
