Auto video editor
An online tool to auto edit a video, start to finish
Zupum is an online auto video editor. You upload a raw clip in any format, the AI auto-edits it — captions, B-roll, music, sound effects, transitions, colour — and you download the finished MP4. Nothing to install.
What the auto edit includes
Zupum applies a full publish-ready edit by default rather than one effect at a time. For every minute of footage it places cutaways, hooks, transitions, sound design and a caption track, so the first preview already looks posted-ready.
- Automatic transcription and word-synced captions
- Royalty-free stock B-roll first, AI-generated B-roll when nothing fits
- Graphic cards: lists, checklists, stats and quotes with a circular speaker frame
- Background music matched to pace, plus sound effects locked to each transition
- Auto colour grade, denoise and filler-word ('umm', 'aah') removal
- One-click thumbnail generation for publishing
Auto, but never locked
The auto edit is a starting point. Every cutaway, caption, transition and track is an object you can retime, restyle, replace or delete in the studio — including uploading your own B-roll footage and choosing whether it overlays the original or cuts in.
Works in the browser
Processing happens in your browser session on desktop and mobile. No app store, no plugin, no export queue — press download and the MP4 renders locally at your source resolution.
