AI Video Extender
Continue a clip past the frame where it stopped — upload the last frame, describe what happens next, and the scene keeps going instead of starting over.
AI Video Extender
One clip, then its continuation
Both clips were generated on this page's free engine — the second continues the first from its exact final frame, using the same upload-and-prompt flow this page hands you. Every output is AI-generated, so your seam and your scene will vary. Watch the handoff, not the boat.
The original clip — and where it stops
A paper boat drifts down a rain-water stream in golden light, and after six seconds the clip simply ends — mid-drift, the way every generated clip ends. This is the frame the continuation anchors on: the calmer that final frame, the cleaner the pickup.
Generate a first clipThe extension — same scene, next seconds
The final frame went back in with a continuation prompt: keep drifting, pass the drain grate, spin once in the eddy. The stream, the light and the boat carry over because the continuation starts from the exact pixels the first clip ended on — that is the whole trick, made visible.
Extend your own clipWhat is an AI video extender?
It is the answer to the most common complaint about generated video: the clip is good and then it just stops. A video extender takes the last frame of an existing clip as its starting image and generates the seconds that follow, so the scene, the light and the subject carry over instead of resetting. Chain the trick and a six-second clip becomes twelve, eighteen, as long as the story needs.
The technique is honest and worth understanding, because it is what every such tool actually does under the hood: video models generate forward from an image, so "continuing" means handing the model your clip's final frame and a prompt for what happens next. On this page that flow is explicit — export the last frame of your clip (a paused screenshot works), upload it in image-to-video mode, and describe the continuation.
Explicit beats hidden: you choose the exact frame to continue from, and you can steer the next seconds instead of hoping.
The pair on this page is our own run: a paper boat drifting down a rain stream, generated once, then continued from its final frame with a prompt asking the boat to keep drifting and spin once in an eddy. Watch the cut point — the scene, the light and the boat carry across it.
The honest limit shows there too: the tool preserves what the last frame can see, so motion that is mid-blur at the cut can stutter, and off-screen elements are re-imagined rather than remembered. Pick a calm frame to continue from and the seam disappears; pick a chaotic one and it shows.

How the extension comes together
Last frame in, continuation prompt written, next seconds out — repeat until the story is told.
Seamless pickup
The continuation starts from your clip's exact final frame — same scene, same light, same subject, no reset.
Steerable continuation
The new seconds follow a new prompt, so you can hold the motion or turn the scene while keeping the world.
Continuation pairs naturally with the other camera tricks here: freeze the peak with the bullet time effect and carry on past the release, keep a dance running longer with the twerk generator, or start from a still photo in the kiss video generator and stretch the moment it ends.
Extend a video in three steps
From a clip that ends too soon to one that ends on purpose.
Capture the last frame
Pause your clip on its final frame and export or screenshot it. Choose a frame where the subject is clearly visible and motion is settled — the model continues what the frame shows, so a clean anchor beats a blurry one.
Upload and describe what happens next
Switch to image-to-video, upload the frame, and write the continuation the way you would direct the next shot: what keeps moving, what changes, where the camera goes. Repeat the scene's look in words — same light, same setting — to hold continuity.
Generate, then chain if needed
Run the extension and cut it onto the original in any editor. Need more? Take the new clip's last frame and go again — each pass adds seconds while the scene carries forward. A failed run is never charged.
Who stretches a clip
Anyone whose best generation ended four seconds before the idea did.
Storytellers on short clips
A six-second cap forces scenes to end mid-thought. Chaining extensions lets a generated scene run to its natural beat — arrival, action, aftermath — instead of the model's timer.
Editors saving a good take
When one generation finally nails the look, re-rolling is a gamble. Continuing from its last frame keeps the take you fought for and buys the extra seconds the edit needs.
Video extender FAQ
Common questions about continuing clips on Kavel.
Just the final frame. The generator takes an image as its starting point, so the flow is: pause on the last frame, screenshot or export it, upload, and prompt the continuation. It is one honest step more than a magic button — and in exchange you choose exactly which frame the continuation grows from, which is where most of the control lives.
The starting pixels match perfectly — the continuation begins on your exact final frame. From there the model re-imagines motion, so the match stays strong for scene, light and subject, and weakest for fast motion crossing the cut and for anything off-screen, which the model never saw and must invent. A settled anchor frame and a prompt that restates the scene's look give the cleanest seam.
There is no hard cap — each extension's last frame can seed the next. Drift is the real limit: tiny changes compound with each generation, so scenes hold together well for two or three chained passes and get progressively looser after that. For long pieces, plan cuts where a scene change is natural and start fresh anchors there.
Yes — that is half the point. The continuation follows your new prompt, so from the same anchor frame you can keep the motion going, introduce something new, or swing the mood. The world carries over; the direction is yours.
Each extension is a normal generation on Kavel's free video engine, and new visitors start with free credits. The estimate shows before each run and a failed generation is never charged — so a twelve-second story costs two short runs, not an upgrade.

What each model costs in credits
You're only charged for successful generations. The exact estimate in the generator varies by model, length, resolution, audio, and number of images.
| Type | Model | Credit cost |
|---|---|---|
| Video | Seedance 2.0 | 5s 720p image-to-video ≈ 188 credits; text-to-video ≈ 308 credits. Scales with resolution and length. |
| Video | Seedance 2 Fast | Faster and lower cost. 5s 720p text-to-video ≈ 248 credits. Mini is cheaper still. |
| Video | Veo 3.1 | Billed per video (Lite). About 34 credits at 1080p, about 23 at 720p. |
| Image | Nano Banana 2 | Generate or edit from text and images. About 8 credits per 1K image, 12 at 2K, 18 at 4K. |
| Image | Nano Banana Pro | Consistent run times across generations. About 12 credits per 1K or 2K image, 21 at 4K. |
| Image | Nano Banana 2 Lite | Faster, simpler variant. About 8 credits per image. Start here to test. |
