ByteDance2ReferenceNode - ComfyUI Built-in Node Documentation

Complete documentation for the ByteDance2ReferenceNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The ByteDance Seedance 2.0 Reference to Video node uses the Seedance 2.0 AI model to create, edit, or extend videos based on your text prompt and provided reference materials. It can use images, videos, and audio as references to guide the generation process, supporting tasks like video editing and extension.

Inputs

Parameter	Description	Data Type	Required	Range
model	The AI model to use. Seedance 2.0 is for maximum quality, while Seedance 2.0 Fast is optimized for speed. Selecting a model reveals additional required inputs for prompt, resolution, duration, ratio, generate_audio, and optional inputs for reference_images, reference_videos, reference_audios, reference_assets, and auto_downscale.	COMBO	Yes	"Seedance 2.0" "Seedance 2.0 Fast"
seed	A number used to control whether the node should re-run. The results are non-deterministic regardless of the seed value (default: 0).	INT	No	0 to 2147483647
watermark	Whether to add a watermark to the generated video (default: False).	BOOLEAN	No	True / False

Important Constraints:

• At least one reference image or video (provided via the reference_images, reference_videos, or reference_assets inputs) is required for the node to work.
• A maximum of 9 reference images can be used in total (including those from reference_images and reference_assets).
• A maximum of 3 reference videos can be used in total (including those from reference_videos and reference_assets).
• A maximum of 3 reference audio clips can be used in total (including those from reference_audios and reference_assets).
• Each reference video must be at least 1.8 seconds long. The combined duration of all reference videos cannot exceed 15.1 seconds.
• Each reference audio clip must be at least 1.8 seconds long. The combined duration of all reference audio cannot exceed 15.1 seconds.

Outputs

Output Name	Description	Data Type
video	The generated video file.	VIDEO
