Youtube kung-fu on Linux

This is just a collection of commands that I have used in the past to edit video, especially for uploading to online video sites such as YouTube. This entry is small now, hopefully it grows as I figure out how to do more useful stuff.

# Cut a clip from a whole video file (-ss is base, -t is offset)
ffmpeg -sameq -i input.avi -ss 00:1:23 -t 00:02:35 output.avi

# Boost the volume of a video file
ffmpeg -sameq -vol 1000 -i input.avi output.avi
or, see Avidemux tutorial here: http://www.youtube.com/watch?v=w8K0D2t0ysE

# Dump audio of an flv video file to mp3
ffmpeg -i inputfile.flv -f mp3 -vn -acodec copy ouputfile.mp3
