Hello, I'm looking for some software that can mix an audio file with a video file when the video already has some existing sound on it. In particular, I need to mix a bunch of AVI video files with some MP3 audio files.
Does anyone know the name of some software that can do this (preferably free or trial?) If it can mix audio into custom points in the video file, that would be an even bigger plus.

I use the sound editing version....works great...

Multiquence from the link you gave worked pretty good (aside from a little watermark on the top of the movies and the 45sec limit.) Thanks. It's too bad there is not a freeware alternative out there.
