ComfyUI Seedance 2.0 All Reference Video

This custom node adds:

• Seedance 2.0 All Reference Video (8 Person + 7 BG)

It generates a VIDEO output through ComfyUI's official ByteDance Seedance 2.0 API path.

Inputs

• model: Seedance 2.0, Seedance 2.0 Fast, or Seedance 2.0 Mini.
• prompt: text prompt for the generated video.
• person_1 to person_8: person/character references.
• background_1 to background_7: background/environment references.
• seed: rerun control seed.
• watermark: Seedance watermark option.

Seedance 2.0's official reference endpoint supports up to 9 reference images. This node keeps up to 8 person references as independent images and packs background references into one contact sheet when needed, so the ComfyUI node can still accept 15 image inputs while staying inside the official limit.
