Split a video file on the command line

October 13, 2011 Leave a comment

Since it’s so insanely useful and installing/using the common graphical video editors is pretty much a pita:

ffmpeg -ss 00:15:00.0 -t 00:10:0.0 -i <source>.foo -vcodec copy -acodec copy <destination>.foo

Above command clips everything to the 15 minute mark, puts the following 10 minutes into the destination file and then clips everything after that.
If you leave out the -t parameter, everything from the -ss mark to the end gets copied to the destination file. Useful and fast.
