When a good clip ends too soon, continue it. Upload the clip, optionally describe what happens next, and the video extender generates extra seconds that pick up from the last frame.

How to make a video longer with AI

Upload a short clip and get new footage that continues it, in three steps.

  2. 2. Pick a tier and say what happens next Choose Fast, Standard, or Best under Quality. On Fast, also set the Duration of the new footage, from 1 to 15 seconds, and the Resolution; Standard and Best add 5 seconds. Your direction is optional.
  3. 3. Generate and download Press Generate. The clip appears under Your recent creations; open it to save the MP4.

Make a short clip longer

The extender is for a shot that stops a beat too early: an AI-generated clip that ends before the camera move finishes, or a phone clip that cuts off as the chorus lands. The AI reads the end of your clip and generates new footage that carries on from the last frame. It does not slow the video down, loop it, or hold a freeze frame: the added seconds are newly generated.

What an extension costs

Fast is priced by the length and resolution you pick: 33 credits for 5 more seconds at 720p, down to 4 credits for 1 second at 360p. Standard costs 45 credits and Best 179, each for 5 more seconds. A new web account starts with 20 credits, which covers a Fast extension of 3 seconds at 720p (20 credits) or 5 seconds at 360p (19 credits). The price shows on the Generate button, and credits are refunded if a generation fails.

What the video extender can't do

It works on short clips only: the upload can be 15 seconds and 20 MB at most, so it does not lengthen a full song or a long recording in one go, and a result longer than 15 seconds cannot be extended again. A run adds up to 15 seconds on Fast and 5 seconds on Standard or Best. The new footage is the AI's continuation of the scene, so faces, hands, and text can drift as it goes on. It does not follow a song.

Frequently asked questions

How do I extend a video with AI?

Upload the clip, add an optional description of what should happen next, choose a tier, and generate. You get a longer clip that continues the action.

How much longer will it be?

Each run adds a few seconds. Run it again on the result to keep going.

Does it keep the same style?

Yes. The extension matches the lighting, subject, and camera motion at the end of your clip as closely as it can.

What does a video extender do?

It adds new footage to the end of an existing clip. The AI reads the final frames and generates a continuation, so a shot that ends too soon can run a few seconds longer.

Can I extend a video that is longer than 15 seconds?

Not in one piece: the upload limit is 15 seconds and 20 MB. Cut the last few seconds of your video into a separate clip, extend that clip, and join the result to the rest of the video in your editor.
