An AI video extender generates new footage that continues an existing clip. It reads the uploaded video together with your prompt and produces a continuation that follows the original subject, scene, and motion.
AI Video Extender continues a clip you upload beyond its original ending, carrying the action, camera movement, and scene forward. Add a source video, describe what should happen next, and pick one of two video models to generate the continuation.
The new footage is generated from the clip you upload, so it picks up the subject, setting, and lighting that are already on screen instead of starting from a blank prompt and hoping the look matches.
Try it nowA short prompt describes the next beat: keep the camera drifting, let the subject finish a gesture, or move the scene toward a new moment. Clear, concrete direction gives the most predictable continuation.
Try it nowSwitch models from the selector above the upload field. They accept different source formats and offer different duration and resolution options, so choose the one that fits your clip and the look you need.
Try it nowBoth models offer a sound toggle, so ambience and effects can continue into the new section instead of the clip dropping into silence at the point where your original ended.
Try it nowLet a movement that gets cut off, such as a turn, a step, or a pour, play out to a natural end instead of stopping mid-gesture.
Add breathing room to an establishing shot, product reveal, or scenic moment that feels too short in the edit.
Keep a push-in, pan, or orbit going so the shot reads as one continuous take rather than ending on a hard cut.
Stretch a short clip to cover narration, music, or a title card without looping it or slowing the footage down.
Extend toward a pose or framing you can cut from, which makes seamless loops and scene transitions easier to assemble.
Take a short clip you generated elsewhere and add more footage while keeping the same character, setting, and style.
Lengthen a strong clip to match a platform’s pacing or give a hook more time to land before the cut.
Extend product shots and campaign footage you own to fill a required spot length without booking a reshoot.
Patch a shot that ends a few beats too early and needs extra frames to cover a cut or a line of dialogue.
Continue generated clips into longer pieces while keeping the same subject, environment, and visual style.
Add one source video you own or may edit. The upload field shows the file type, size, and length the selected model accepts.
Write what should happen after the last frame, such as the motion, camera direction, and mood, then set the duration and resolution the model offers.
Check the credit estimate, submit, and watch the point where your footage ends and the new footage begins to judge how smoothly they connect.
End your source on a clean, readable frame; a blurry or mid-transition last frame gives the model less to continue from.
Describe the motion and camera direction of the new section rather than restating what is already visible.
Match the output resolution to your original footage so the join is harder to notice.
If one continuation drifts in style, try the other model; they interpret the same clip differently.
Only extend footage you own or have permission to modify.
An AI video extender generates new footage that continues an existing clip. It reads the uploaded video together with your prompt and produces a continuation that follows the original subject, scene, and motion.
Each task takes one source video. The FLUX option is the stricter of the two: it accepts a single file format and caps both clip length and file size. The Seedance option also accepts MOV and WebM files, with a file-size cap. The upload field shows the exact format, length, and size limits for the model you select.
Each model has its own duration control for the generated footage, and the available lengths appear in the settings once you choose a model. Longer durations usually cost more credits.
Yes. Both models require a short description of what should happen next. Focus on movement, camera direction, and mood rather than describing the existing scene again.
The models aim to keep the subject, lighting, and style consistent, but small changes in detail, faces, or on-screen text can appear, especially after fast motion or a scene cut. Review the join and the whole result before publishing.
Generation uses pay-as-you-go credits based on the selected model, duration, and resolution. The estimate beside the Generate button updates as you change settings, so you can check the charge before you submit.
Upload a clip, describe the next moment, and generate footage that continues where your original stops.
