What is an AI video editor?

Kenerate AI's AI video editor is a set of AI tools that each do one edit well: video edit changes a clip from one sentence, extend adds seconds that continue the shot, and auto subtitles, upscaling to 4K, dubbing and lip sync finish it. It isn't a timeline editor: use one for assembly and these tools for the AI steps.

Tips

A good order of operations

What saves renders.

  • Edit the look first, extend second.

  • Subtitle after the final cut, so the timing matches.

  • Upscale last — only the keeper.

  • Dub before lip-syncing to a new language.

  • For assembling many clips, use a timeline editor.

  • Real people need their permission.

FAQ

AI Video Editor questions

What is the best AI video editor?

For AI edits — restyles, extends, captions, upscaling — a tool with several models per job. Kenerate has 11 edit models and 17 extend models; for cutting many clips together, pair it with a timeline editor.

Link to this answer

Can AI edit a video from a text prompt?

Yes — video edit re-renders your clip from one sentence while keeping the motion. The 1980s demo above is a real Wan 3 edit; the Video to video AI page shows more restyles.

Link to this answer

Can it make a clip longer?

Yes — extend continues the shot from its last frame. On Wan 3 you choose how many seconds to add.

Link to this answer

Does it add subtitles automatically?

Yes — the subtitles tool transcribes speech and burns in captions in 10 styles, for clips up to 4 minutes.

Link to this answer

Is there a free AI video editor?

Partly. A free account gets 25 sign-up credits, and those work on auto subtitles, upscaling, dubbing and lip sync, so you can caption or upscale a clip without buying anything. Prompt edits and extends use the video models, which need a credit pack.

Link to this answer

Is it a timeline editor?

No. These are AI tools for single clips; use a timeline editor to assemble many clips.

In depth

AI Video Editor, explained

AI edits vs timeline edits

A timeline editor cuts, trims and arranges clips. AI editing changes what's inside a clip: its style, its length, its captions, its resolution, its language. Most projects need both — AI tools for the hard parts, a timeline for assembly.
