MovieUtilities CMM is a package of three CMM plug-ins which let you manipulate QuickTime
movies in many useful ways. ConvertToMovie lets you convert sounds, pictures, MPEG files, MIDI files, karaoke and other files to QuickTime movies. MovieConverter lets you convert movie tracks to pictures, sounds, MPEG files, MIDI files and
more, depending on the kind of movie track. MovieMerger lets you merge multiple movie tracks into one single QuickTime movie. You only
need to select multiple movies and control-click them, then choose "Merge Movies..." from the
contextual menu.
MovieMerger is very useful if you wish to quickly merge a video track with a sound track, for
example.
