Extend

Extend a video with AI - make any clip longer

Continue a video past its last frame with LTX-2.3. The model generates new footage that matches the motion and style of the clip, with optional audio continuation.

Extend - generated continuation

The clip ends before you need it to

A generated shot is a second too short, a loop needs more runway, or a scene has to hold longer to land. Re-rendering the whole thing is slow and rarely gives you the same shot.

Continue from the last frame

Video Extend takes the tail of your clip as reference and generates new frames that carry the motion and style forward. Give it a prompt to steer where the shot goes, and it keeps the existing footage intact.

Audio can continue too

Optionally extend the audio alongside the video so the continuation does not cut out. Choose how many seconds of new footage to generate.

How to extend a video

  1. Upload your clip - filmed or generated, both work.
  2. Choose how many seconds of new footage to add.
  3. Optionally write a prompt to steer where the shot goes, and toggle audio continuation.
  4. Generate, then download the extended clip.

FAQ

Does it loop the video or generate new footage?

It generates genuinely new frames that continue from the end of your clip - not a loop or a freeze.

How many seconds can I add?

You choose the extension length per job. See the tool for the current maximum.

Can it keep the audio going?

Yes, audio continuation is an optional toggle.

What does it cost?

1 credit per second of new footage. See the pricing page.

How do I extend a video?

Upload the clip, choose how many seconds to add, optionally describe where the shot should go, and generate. The new footage continues seamlessly from your last frame and downloads as one clip.

Can I extend a video that has voice or music?

Yes. Turn on audio continuation and the soundtrack is extended along with the picture, so music, ambience and voice carry into the new footage instead of cutting to silence. It continues the existing sound - it does not script new dialogue.

Does it work on real footage or only AI-generated videos?

Any video works. The model continues whatever you upload - filmed footage, screen recordings, animations, or generated clips.
