Video Composer: cut your clips on the beat.

A beat-locked video composer and DJ visualizer that runs entirely on your computer. Play a track (or go live from a mic or line in), let the Auto-Editor cut your clips on the beat, add titles and credits, then export a finished MP4. Rendered on your machine: no internet, no uploads.

BSSMNT mid-edit: the Clip Auto-Editor cutting six clips to a track, with the timeline, sound panel and clip stack

Who it’s for

DJs, content creators and video hobbyists.

BSSMNT streamlines making a music video: you bring the song and the clips, the system does the first pass (placement, timing, transitions, all from the music), and you stay in control of every decision it makes.

Serious enough to grow with you, simple enough that you’ve never needed to open an editor before.

What it does

Cuts your videos and images on the beat.

Titles, rolling credits and free text, timed on the timeline.
