Programatically remove chunks from a video file?
 

I need to remove sections from video files (from the middle and the end) on the command-line. Generally these will be mp4 and avi files.

For instance, I have a .mp4 file which is 32:30 minutes long. I'd like to remove from 2:49 to 3:20, and remove the last 60 seconds.

Any ideas on how I can achieve this?

You can use mencoder for this. You can extract pieces from the file, eg:

(-ss is the skip time, -endpos is the end point)

You can then use mencoder to join the result pieces together, eg:

You can do the same thing with ffmpeg.

You could also consider using mpgtx.
