AI Video Editor: Edit Videos by Describing the Change

This AI video editor changes footage based on a sentence. Attach a clip and say what to change (“make it snow”, “turn it into an anime scene”, “add a neon sign that reads OPEN”) and the model edits the video while leaving the rest of the shot alone. There's no timeline, masking or keyframing to learn, and it all runs online in your browser.

How to edit a video with AI

  1. 1

    Attach your clip

    Upload your clip or paste a link. The editor opens with Seedance 2.5 in Edit mode.

  2. 2

    Describe the edit

    Say what changes and what doesn't: “Replace the grey sky with a golden sunset; keep the people and the car unchanged.”

  3. 3

    Generate and compare

    Generate the edit, compare it with the original in your gallery, and tweak the wording if it needs it.

What you can do with an AI video editor

  • Change the setting: a new background, different weather, another season or time of day.
  • Restyle it: turn footage into anime, claymation, watercolour or a film look.
  • Add or remove things: a product in someone's hand, a sign on a wall, or something distracting taken out of frame.
  • Add text to a video: titles, signs and short captions written into the scene itself.
  • Change how a subject looks, such as an outfit, hair colour or material, while the motion stays the same.
  • Keep a clip going: switch to Extend mode, or use the AI video extender.

Models for editing video

Seedance 2.5 is built for precise edits that leave the rest of the shot alone, and switches between Edit and Extend with one setting. Gemini Omni Flash 1.1 edits and extends video with output up to 4K. Wan 3.0, MiniMax H3 and FLUX 3 Video take video as input for video-to-video restyling: your footage sets the motion and your prompt sets the new look.

How to add text to a video with AI

Describe the text and where it should sit in the scene: “Add the words ‘Grand Opening’ in gold letters on the shop window.” AI-rendered text works best for short phrases of two to six words. For subtitles and long captions, a regular caption tool is still more accurate. Use AI edits for text that should look like it's part of the world.

Is this the right AI video editor for you?

It won't replace your regular editor. If you need precise cuts, multi-track timelines and colour grading, keep using it, and come here for the jobs that used to need VFX: replacing skies, restyling shots, adding objects. Starting from nothing? Generate footage first with text to video AI or the AI image to video tool.

Frequently asked questions

Is it free?

Signing up is free, and so is looking around: every model, setting and tool is open before you pay anything. Generating a video costs credits, and the price depends on the model, the length and the resolution. The estimate sits next to the Generate button, so you always see it before you commit. A quick 3-second test at 360p on Gemini Omni Flash costs about $0.09.

What is an AI video editor?

It's a tool that edits footage from written instructions. Instead of masking and keyframing, you describe the change and a video model generates the edited clip.

Can I edit a video I shot on my phone?

Yes. Upload it straight from your phone or computer (MP4 and MOV both work). Short, steady clips give the cleanest results.

Can I add text to a video?

Yes. Put the text in quotes and say where it should appear. Short phrases come out best; for long subtitles, use a caption tool.

Is there a length limit for editing?

It depends on the model. Most edits work on short clips, so split longer footage into shots and edit them one at a time.
