What does AI Video Extender do?

It continues a 2–15 second MP4 from the final frame. You guide the next action with a prompt, and the download includes the original clip followed by the generated continuation.

Which videos can I extend?

AI Video Extender accepts MP4 source clips between 2 and 15 seconds.

How do I get a more natural video continuation?

Use a stable source clip with clear motion and a readable final frame. Continuity works best when the ending frame gives the model enough context for what should happen next.

How many credits does video extension use?

Credit cost depends on the extension length and is shown in the workspace before you generate.

What happens to videos I upload to extend?

Uploads are processed to complete your task. Generated files are kept according to your plan. See our Privacy Policy for details.
