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 a generative model re-renders the frames with that change applied, keeping the original motion and timing. The AI video editor runs entirely in the browser: no software install, no keyframing.

Two broad families: style transfer, where the whole clip is repainted in a new look such as anime, watercolor, or a film grade; and local replacement, where one element changes — clothing, objects, weather, background, lighting — while everything else stays as shot. Both are driven by the same instruction box.

Wan 2.7 Edit, Alibaba's instruction-based video editing model, and HappyHorse Edit, a lightweight alternative for longer clips. They sit behind the same upload panel with one credit wallet, so switching models is one click rather than a new account.

MP4 or MOV, up to 100MB. Wan 2.7 Edit accepts clips of 2 to 10 seconds; HappyHorse Edit accepts 3 to 60 seconds. The uploader validates duration and size locally 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 exact outfit, a specific character design, a brand texture. The model matches the reference instead of guessing from the description.

Yes. The editing models preserve the structure of the source — camera movement, choreography, scene pacing — and re-render only the change you asked for. That is what separates prompt-based video editing from generating a new video from scratch.

Edits are pay-as-you-go with credits — no subscription required. The same credit wallet covers every tool on AIGenTools, and a 720p render costs half the credits of a 1080p render, so iterate at 720p and save 1080p for the final take.
