AI Video Extension Tool
Make any video clip longer with Seedance 2.0. The AI video extension tool picks up from the last frame and continues the scene naturally — same characters, same style, same motion direction.
Extend Any Video Clip Seamlessly
Upload a short video clip and Seedance 2.0 extends it. The video extension AI analyzes the final frames and generates new footage that continues the scene without visible cuts.
Got a 5-second clip that needs to be 15 seconds? Seedance 2.0's video extension tool can add new frames that continue the action, the camera movement, and the overall feel of the original footage. It works on AI-generated clips and real footage alike. The transition between original and extended footage is smooth enough that most viewers won't notice where the original ends.
Guide the Extension with Prompts
Optionally write a prompt to tell Seedance 2.0's video extension tool what should happen next. Without a prompt, it continues the existing motion. With one, you can change the scene direction.
Say you have a clip of someone walking down a street. Without a prompt, the video extension continues the walk. Add a prompt like "the person stops and looks up at the sky" and Seedance 2.0 changes the action mid-clip. This makes video extension useful not just for lengthening clips but for building multi-shot sequences from a single starting point.
