AI Video Extender

Upload your clip to a chat with Kai, Kapwing’s AI Assistant, and describe how you want it to continue. Include the next action, camera movement, and any details that should stay the same, such as the character’s appearance or the lighting. Kai will automatically generate a video that starts exactly from the end frame of your original clip, so you can seamlessly merge the two videos.

Review the generated continuation and refine it with follow-up prompts. Then bring your clips into the editor to join them, trim the transition, and adjust the final length.

Yes, Kapwing uses AI models like Seedance 2.5 and Minimax H3 to generate a new clip with the exact character appearance, setting, lighting, style, and positioning on the end frame of your original video. Your generation will continue from the point your video ends, following the directions you provide in your prompt.

The AI Video Extender creates a new clip that plays naturally after the original, making both clips feel like one continuous shot.

Explain what should happen immediately after the clip ends. Describe the subject’s action and camera movement, then identify the details you want to preserve. A focused continuation gives AI clearer direction than simply asking it to “make the video longer.”

For example: “Continue as the woman walks toward the window. Follow slowly from behind, keeping the same outfit, apartment, and warm evening light.” You can also prompt for a multi-scene video extension by describing changes to the setting, lighting, and camera angle.

Yes, if you like the existing footage but want the scene to continue, extend the clip and describe a new final moment. Complete a product reveal, finish a character’s movement, or direct the camera toward a different view.

If you want to replace part of the current ending, trim your video in Kapwing to the point where the new direction should begin. Use that shortened clip as the reference for your extension, then join the footage into the revised sequence.

No, Kapwing's AI Video Extender automatically works from the end frame of your uploaded video, so there's no need to upload additional start frames or end frames. However, if you want your newly extended video to end on a specific frame, you can upload that and explain in your prompt how the action should progress from the original clip to that image.

You can also upload references for new characters or objects you want to introduce. Describe which image represents each element and how it should appear in the scene. If you need to create a reference first, use Kapwing’s AI Image Generator.

Yes, upload an exported AI-generated clip and use it as the reference for a continuation in Kapwing. This gives you a way to build on short generations from tools such as Grok or Sora without recreating the original scene.

You can also extend clips made with Kapwing’s AI Video Generator. In either workflow, describe the next moment and the visual details you want to carry over from the source video.

Extending a video adds time by generating footage beyond the original ending. Use an AI video extender when you want to continue an action, create a new ending, or make a clip longer.

Expanding a video adds space around its frame by generating additional background content. That workflow helps change aspect ratio while keeping the original picture visible. For a still photo, Kapwing’s AI Image Extender can help you expand the framing and background.

Kapwing supports generating video clips up to 30 seconds long using models like Seedance. To extend videos beyond that, you can continue creating additional clips, then merge them using the Studio.
