Guide Your Video Extension with a Prompt
Keep the homepage workflow concise, then use a focused resource when you need more control.
01 / PROMPT
Give the Extension a Clear Direction
The source clip already contains much of the visual information the generation needs. You usually do not need to redescribe the entire scene. Focus on the new moment you want to add.
“The cyclist continues down the street while the camera follows from behind.”
Clear directions are especially useful when subject movement or camera behavior matters.
For detailed prompt structures, movement language, camera terminology, and examples, use the dedicated prompt resource.
Using the tool begins with the video you already have.
Choose the source clip, decide whether the new footage belongs before or after it, add a short direction, and generate the extension using the available output settings.
For a complete walkthrough of the interface, generation process, preview, and download workflow, read the dedicated usage guide.
An AI Video Extender generates additional footage before or after an existing clip. The source video provides visual context while your direction guides the new section.
Can AI make an existing video longer?
Yes. AI extension can add newly generated footage when you need more visual content rather than repeated playback.
