What is the easiest way to change soundtrack of a movie clip? We recorded a clip using our camera, but the sound is not very interesting, hence we would like to use some music instead (we have an mp3 file). How can we swap the original sound in the clip for the one from mp3?
You should be able to replace the audio track of a video file using
mencoder input.avi -o output.avi -ovc copy -oac copy -audiofile track.mp3
Warning: untested command.
I ended up using Kdenlive, which is a nice gui. It can do lots of other things, but I managed to figure out in a few minutes how to do this particular thing.
