Multi-Input Character & Background Swap Process

  1. Open the Seedance 2.0 platform and access the demo or video editor section.
  2. Upload the source video featuring a green screen as the primary input.
  3. Enable the 'multi-input' feature in the settings panel.
  4. Prepare and upload three separate reference assets: an image for Character 1, an image for Character 2, and one Background image.
  5. Write your prompt in the text field by 'tagging' each reference input (e.g., Referencing the uploaded character 1, character 2, and background assets).
  6. Click the 'Generate' button to start the AI rendering process.
  7. Wait for the generation process to complete (estimated time is around 60 seconds).
  8. Review the final result to ensure the original motion is preserved while the characters' appearance and the environment have changed according to your references.
