Cut a video to the beat of the music

PandaStudio finds the beats of a music track on your computer, shows them as markers on the timeline that images, B-roll and video overlays snap to, and can place a whole montage so each picture changes every beat, every 2 beats or every bar.

Once a music track of at least 4 seconds is on the timeline, a Beats button appears in the timeline toolbar: it shows beat markers on the music, and items you drag snap to them (hold Alt / Option to drag freely). Select the music track and the Beats panel shows its tempo in BPM and how many beats it found. With pictures or B-roll over the track, choose How often to change (Every beat, Every 2 beats or Every bar) and click Place on beats: the items are retimed in their current order so each one changes on the beat, and items that do not fit before the music ends are left as they are. The analysis runs locally, is cached per audio file, and follows the track's trim, start and loop. It works on music: narrations, sound effects and transcribed tracks are not treated as beat tracks, and speech or ambience with no steady beat reports No steady beat. Place on beats moves overlays (images, B-roll and overlay videos); it does not split the main video. To cut the main clip on a beat, use the beat markers to place the playhead and split there.
