  I have an MPG video and a CSV of times. I am searching for a way to automatically generate clips from the video using those times.
  
  So at each time position a clip is generated with 10 seconds either side of the time resulting in a 20 second clip.
  
  I have investigated scene detectors and trying to import markers into Adobe Premier etc, but with no luck.
  
  Any ideas?
  
  Thanks.
