AI Video Editor edit and generate with a prompt

An AI video editor lets you change a video by describing what you want instead of pushing keyframes around a timeline. In Vivideo you can edit footage you generated or uploaded with a prompt — trim and cut, add captions and subtitles, drop in AI voiceovers and avatars, apply your brand kit, then extend, remix and export in HD without a watermark.

How an AI video editor works

An AI video editor replaces the dense timeline of traditional software with plain language. Instead of dragging clips, setting keyframes and hunting through menus, you tell Vivideo what you want changed — trim the intro, swap the background, restyle a shot, tighten the cut — and it applies the edit. You can start from a video you generated with a prompt or from footage you upload, and refine it the same way every time.

The core of editing in Vivideo is the follow-up prompt. Generate or import a clip, then describe a change in a sentence: shorten it to fifteen seconds, recut to a punchier opening, regenerate the scene in a different style, or extend the shot a few seconds longer. Because each edit is a prompt rather than a destructive timeline operation, you can branch, compare takes, and remix a version you like without losing the original.

Editing is more than cutting. Vivideo lets you add captions and subtitles, layer an AI voiceover from a script, drop in an avatar presenter, and apply your brand kit so your logo, colors and fonts are consistent across every clip. Hundreds of templates give you a starting structure for social formats, and the whole roster of 30+ AI models is available when an edit means regenerating a scene rather than trimming one.

A good editing prompt is specific about the change and the intent. 'Cut the first two seconds and start on the close-up' or 'restyle this shot as warm, cinematic, shallow depth of field' gives Vivideo far more to work with than 'make it better'. Keep one change per prompt, preview the result, and stack edits — trim, then caption, then add voiceover — so each step is easy to keep or undo. The same review-and-refine loop that powers generation powers editing.

Captions, voiceover and localization turn a rough cut into a publish-ready video. Add subtitles for silent autoplay feeds, generate an AI voiceover in a natural voice, or pair the clip with an avatar that reads your script. Because Vivideo also translates and dubs, one edited master can become a version for every market — the same edit, re-voiced and re-captioned, without re-shooting or re-editing from scratch.

Editing in Vivideo connects to the rest of the studio. In Auto-Generate, one prompt produces a finished video you can then refine. In Agentic Chat, a planning agent assembles scenes, avatars and voices into a longer story up to 10 minutes — and you edit any scene by talking to it. In Manual Mode you drive a specific model yourself. Whichever way the clip was made, the editor is the same: describe the change and keep the take that's right.

Teams use the AI video editor to turn one master into many — trimming a long explainer into platform-ready cuts, re-captioning a single ad for TikTok, Reels and Shorts, swapping a voiceover for a new market, or refreshing last quarter's video with a quick restyle. Because output is on-brand by default and exports are HD with no watermark, what comes out of an edit is ready to ship, not a draft that needs a separate finishing pass.

AI editing is fast but not magic, and knowing the edges keeps you efficient. On-screen text and fine detail can wobble when a scene is regenerated, and a character can drift between cuts, so add captions as a layer rather than baking them into a prompt, lock a recurring presenter with an avatar, and lean on remixing and regeneration when an edit misses. Vivideo previews the credit cost and lets you generate a few variations, so you only spend on the final, no-watermark export once the edit is right.
