AI Video Editor — Edit Any Video with a Prompt

An AI Video Editor changes existing footage from a text instruction instead of a timeline. You upload a clip and describe the edit — restyle the scene, swap an outfit, replace the background — and it re-renders the frames with that change, keeping the motion and timing. Everything runs in the browser: no install, no keyframing.

Upload an MP4 or MOV, type the change you want, and run it — AI Video Editor re-renders the clip in the browser with your edit applied, nothing to install. Download the finished video with no watermark.

Two broad families: style transfer, where it repaints the whole clip in a new look such as anime, watercolor, or a film grade; and local replacement, where one element changes — clothing, objects, weather — while the rest stays as shot.

AI Video Editor uses Wan 2.7 Edit, Alibaba's instruction-based video editing model, and HappyHorse Edit, a lightweight alternative for longer clips. They share one upload panel and one credit wallet, so switching models is one click, not a new account.

MP4 or MOV, up to 100MB. In AI Video Editor, Wan 2.7 Edit accepts clips of 2 to 10 seconds; HappyHorse Edit accepts 3 to 60 seconds. It validates duration and size before you spend anything.

Yes — attach up to one reference image on Wan 2.7 Edit or up to five on HappyHorse Edit. References pin down what words struggle to: an outfit, a character design, a brand texture. AI Video Editor matches the reference instead of guessing.

Yes. AI Video Editor preserves the structure of the source — camera movement, choreography, pacing — and re-renders only the change you asked for. That separates a true edit from generating a new video from scratch.

Write the instruction the way you'd brief an editor — name what changes and what must stay — and attach reference images when the look matters. Iterate at 720p to keep credits low, then switch AI Video Editor to 1080p for the final render. Paid accounts unlock higher limits and priority; the same workflow applies on free credits.

Yes. Upload a clip, describe the change, and AI Video Editor returns it in the same frame and timing — ready to repost vertically for TikTok, Reels, and Shorts or wide for YouTube.
