How to extend a video with AI

01
Upload the clip you want to extend
Start with a short MP4 or MOV that already ends where the continuation should begin. Files up to 100MB work well for demos, social edits, product shots, and quick tests.
02
Choose a model and extension settings
Pick a video model, then set the controls it offers, such as duration, resolution, aspect ratio, or audio. These options can change when you switch models.
03
Write the next beat
Use the prompt box to describe what happens after the current ending. Keep the source subject, camera direction, and scene continuity clear.
04
Create, review, and download
Select Create, check the extended clip for motion, framing, lighting, and pacing, then download it or adjust the prompt for another run.

What AI Video Extender can add to a clip

AI Video Extender generates new frames after your uploaded clip, so the shot can keep moving instead of stopping, looping, or cutting away too soon.

Continue a person or camera move

Add frames after the current ending so a walk, pan, push-in, or other visible motion can keep going for a few more seconds instead of stopping abruptly.

Carry a scene into the next beat

Extend a doorway, reveal, approach, or transition so the action can move into the next moment while staying tied to the uploaded footage.

Hold a product shot longer

Give a product, object, or hero frame a few more seconds on screen so there is room for captions, voiceover, or a CTA without cutting away.

Keep the extended clip close to the original

Most drift starts at the handoff point between the uploaded clip and the generated frames. Use this section to keep the subject, camera, lighting, and pacing consistent.

Start from a readable ending

Use a clip that ends with a clear subject, understandable motion direction, stable lighting, and minimal obstructions. Avoid hard cuts, whip pans, heavy motion blur, or large overlays at the handoff point.

Anchor what should stay consistent

Name the subject, motion, camera behavior, and scene condition you want to preserve. For example: the product keeps rotating slowly as the camera pushes in, studio lighting stays soft and even.

Change the right variable when results break

If motion goes the wrong way, rewrite the prompt. If the extension drifts from the shot, shorten the duration. If the look changes too much, try another model. If none of that helps, start from a cleaner ending.

Extend in shorter passes when needed

For busy motion or higher-stakes shots, generate a shorter continuation first. If it works, use that result as the next source clip instead of forcing one long extension all at once.

Ready to extend a video

Turn a short ending into usable footage.

If the clip already works but stops too soon, use AI Video Extender to add a few more seconds while keeping the same subject, motion, and scene.

AI Video Extender FAQ

Answers for choosing the right source clip, prompt, and extension length.

What does AI Video Extender do?

AI Video Extender adds new frames after the end of an uploaded clip. It is for continuing time from existing footage, not replacing the whole scene or generating a new video from scratch.

How is AI video extension different from looping a clip?

Looping repeats frames you already have. AI video extension tries to generate new frames that follow the original motion, framing, and scene direction, so the ending can move forward instead of visibly repeating.

What kind of clip should I upload?

Use a short MP4 or MOV with a clear subject and motion that is easy to follow near the ending. Clips are harder to extend when they end on a hard cut, fast blur, crowded scene, or heavy overlay.

Do I still need to describe the next beat?

Yes. The uploaded clip gives the model visual context, while the prompt tells it what should happen after the current ending. Keep the direction short and concrete.

When should I use AI Video Extender instead of other video tools?

Use AI Video Extender when you already have a clip and want to continue it from the ending. Use Text to Video for a new scene from a prompt, Image to Video to animate a still frame, and Video to Video to restyle existing footage.

What should I change if the extension drifts?

If the motion goes the wrong way, tighten the prompt. If the image drifts from the source clip, try a shorter duration. If the look changes too much, test another compatible model.

Can I control duration and output settings on this page?

Yes, when the selected model supports them. You may be able to set duration, resolution, aspect ratio, and audio before generation, so check the available controls after you choose a model.
