does anyone know of a free program that would allow me to dub over a video?
hmm thats a good one I know several programs that will do it but free ones. You might was to see was the build in microsoft movie maker will let you do. I know that is standard on all pc with windows ME or later.
Built in Movie Maker will do it... It must be a compatible format tho, or made yourself. if you have a video input card, you can easily do it. they start at 25 bucks at newegg.com
