title: Extract chunks from video file
body: <p>Is it possible to write Python code that gets a video file (mpg, avi, wmv, mov, etc) and a time interval (e.g. from 5_min-10_secs-11_ms to 10-min_15-secs-40_ms) and create a small video from this interval?</p>
  
  <p>I know this is possible with ffmpeg, mencoder and other programs, but I'd like to do this in Python code. </p>
