ByteDance2TextToVideoNode - ComfyUI Built-in Node Documentation

This node uses ByteDance’s Seedance 2.0 API to generate a video from a text description. It sends your prompt to the selected model, waits for the video to be processed, and returns the final result.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The model to use for video generation. Selecting a model will reveal additional required inputs for the prompt, resolution, aspect ratio, duration, and audio generation. “Seedance 2.0” is for maximum quality; “Seedance 2.0 Fast” is for speed optimization.	COMBO	Yes	`"Seedance 2.0"` `"Seedance 2.0 Fast"`
`seed`	A seed value (default: 0). The node will re-run if this value changes, but the results are non-deterministic regardless of the seed.	INT	No	0 to 2147483647
`watermark`	Whether to add a watermark to the video (default: False). This is an advanced setting.	BOOLEAN	No	True / False

Note: The model parameter is a dynamic combo. When you select a model, it will reveal several required sub-parameters that must be filled in, including the text prompt, resolution, aspect ratio, duration, and whether to generate audio. The prompt text must be at least 1 character long after removing whitespace. The “Seedance 2.0” model supports 480p, 720p, and 1080p resolutions, while “Seedance 2.0 Fast” supports 480p and 720p resolutions.
