Fit a music track to a video and lay it under the video, such as a launch film, a product demo, an ad, a reel or a Remotion or HyperFrames composition. Makes the track exactly as long as the cut by cutting or looping whole bars, lands its drop on a chosen second, ends it with a fade that resolves on a beat, ducks it under a voice-over, sets its loudness, writes every beat and bar as frame numbers, and with the video given writes the video with the track under it. Use it whenever a track (from a music model, a library or the user) has to fit a video's length, has to go under a finished video, or the cuts should land on the beat.
