AI video extender
Your clip ends too soon? Keep it going.
Extend adds new seconds after your video's last frame or a lead-in before its first, with the same people, place, light and color. You get the whole longer video, ready to post.
How it works
- 1
Upload your video
Add an MP4 or MOV. Extend reads the scene and suggests what could happen.
- 2
Choose before or after
Pick where the new part goes, how long it is, and describe what happens or pick an idea.
- 3
Get the longer video
Click Generate. You get the full video with the new part joined on, plus the new part on its own.
What you can do
No visible seam
The new part starts on your last frame, or lands exactly on your first, so motion carries on without a cut or a fade.
Same people, same look
Faces, outfits, the place, light and color grade stay the same. Turn any of them off when you want a change.
Ideas from your scene
Extend looks at your video and suggests what could happen next. Pick one or write your own in plain words.
You direct the shot
Choose the camera move, cut to a new angle, add reference photos of a person or product, or start from your own image.
Sound that fits
The new footage comes with matching ambience and effects. Add a spoken line, or keep it silent.
As long as you need
Add up to 30 seconds per run, then extend the result again to build a longer scene.
Questions
How do I make a video longer with AI?
Upload your clip, choose After to continue it or Before to add a lead-in, set how many seconds to add and click Generate. Extend creates new footage that matches your clip and joins it on, so you get one longer video.
Will the new part look like my video?
Yes. Extend reads your clip first and keeps the same people, clothing, place, lighting and color grade. Reference photos help keep a face or product exact. Results depend on the clip, so preview before you post.
Can I add footage before my video starts?
Yes. Choose Before. Extend creates a lead-in that ends exactly on your first frame. It starts on a moment imagined a few seconds earlier, or on your own image.
How long can the extension be?
From 4 to 30 seconds per run. For more, open the result and click Extend again: the longer video becomes your new clip.
Does it work with real people and real footage?
Yes, it works with phone footage, talking-head videos and AI-generated clips. Only extend videos you own or have the rights to use.
What happens to the sound?
Your original sound stays as it is. The new part gets matching ambience and sound effects, or a spoken line if you add one. You can also make the new part silent.
How much does it cost?
Extend is billed in credits by quality and the number of new seconds, and you see the exact cost before you generate. If a generation fails, the credits are refunded automatically.
