Seedance 2.0 Video-Extend

Seedance 2.0 Video-Extend appends a new cinematic continuation to an existing video. The model generates a fresh segment from the input video's last frame and a natural-language prompt, then the original and new segment are concatenated into a single output.

Key Features

  • Seamless continuation — Generation starts from the input video's last frame so the join is visually consistent.
  • Optional target last frame — Provide last_image to steer the new segment toward a specific end frame.
  • Director-level control — Camera movement, lighting, shadows, and character performance via prompts.
  • Native audio synchronization — Audio from both the original video and the new segment are preserved in the final output.

Parameters

ParameterRequiredDescription
promptYesDescribe the cinematic continuation.
videoYesInput video URL. Generation continues from the last frame.
last_imageNoOptional target last-frame URL. Interpolates from the input's last frame to this image.
durationNoLength in seconds of the new segment (4-15, default 5).
resolutionNo480p, 720p (default), or 1080p.
enable_web_searchNoEnable web search for real-time context.

How to Use

  1. Upload the input video. The new segment will be appended to it.
  2. Write the prompt. Describe the continuation in cinematic detail.
  3. (Optional) Upload a target last frame. The new segment will interpolate to this image.
  4. Pick a duration and resolution.
  5. Run. Receive the original video plus the new segment concatenated into one output.

Pricing

Notes

  • Pricing is based on the new segment length only — the input video is not re-billed.
  • Aspect ratio of the new segment matches the input video's last frame automatically.
  • Native audio generation is included for the new segment; the original video's audio is preserved.
