Upload a video, describe what should happen next, and generate a short continuation you can review before using. Choose an extension length and output resolution in the workbench.
An AI video extender generates a short continuation from the end of an uploaded clip. Describe the next beat, select an available duration, and inspect the result alongside the source. It is useful for adding a little breathing room to a shot; it is not a loop maker, slow-motion effect, freeze-frame timer, canvas expander, or full timeline editor. For broader changes to an existing clip, use AI Video Editor.
A useful extension starts with a clear description of what happens next: a hand finishes a wave, a cyclist reaches the bend, or a product settles after a turn. The model uses the source clip and your prompt, so describe continuity in motion, setting, and light rather than asking for an unrelated new scene.
The extend control offers a selectable duration, including a five-second default, and the workbench exposes the resulting credit estimate before processing. Review the join at the original ending and the generated opening; a continuation can drift, so keep the source and output available for comparison. If grain makes the join hard to judge, try Video Denoiser before comparing the clips.
Listen across the transition as well as watching it. Dialogue, ambient sound, and music can make an otherwise useful continuation feel abrupt. Compare the source and generated clip, then finish sound work in your editor if needed. The extender does not expose a separate audio-extension control, so check the result rather than assuming that sound continues automatically. If the finished shot needs a new spoken track, use AI Lip Sync Tool to match the lip movements.
Upload a supported clip, describe the continuation, choose the available output settings, and review the result.
Use an MP4, MOV, or WebM video up to 200 MB and 120 seconds, with dimensions no larger than 4096 pixels. Keep a local copy of the source.
Write one concrete continuation prompt that names the next action and preserves the source's subject, setting, motion, and light. The workbench shows the available model and estimate.
Select an available extension duration and resolution, process the job, and inspect the seam. Download or continue editing only after the generated opening fits your source.
Describe the continuation instead of manually rebuilding every frame.
Choose an available duration for a short addition to the source clip.
Select the resolution exposed by the selected video model. For a separate resolution enhancement step, explore Video Upscaler.
The input clip remains the visual reference for the generated opening.
Inspect the join and the new motion before carrying the clip into an edit.
Use a reframe, slow-motion, loop, or editor tool when that is the actual job.
The workbench exposes the available extension duration for the selected model, with a five-second default in the extend tool. The model and source constraints can limit what can run, so check the current controls and estimate rather than assuming any length or unlimited extension.
No. It generates a continuation from the source clip's ending. It does not promise a loop that returns to the first frame. Use a loop workflow when repeated playback is the goal.
The extend tool's controls cover a continuation prompt, duration, and resolution; they do not expose a separate audio extension control. Review the generated result's audio behavior and finish sound work in an editor when needed.
No. Slow motion changes playback timing and a freeze frame holds an existing image. AI extension generates new frames after the source ending, so choose the method that matches the edit you need.
Extension adds time after the clip. It does not reframe the canvas. Use AI Video Reframe or a crop workflow when you need a different aspect ratio.
No guarantee is implied. Similar motion, lighting, and a specific prompt can help, but generated frames may drift in identity, details, or camera behavior. Compare the seam and revise or edit the result when it does not fit.
Upload a clip, describe the next beat, and review a short AI-generated continuation in the workbench.
