ByteDanceTextToVideoNode - ComfyUI Built-in Node Documentation

The ByteDance Text to Video node generates a video using ByteDance models through an API based on a text prompt. You provide a prompt and choose settings such as the model, resolution, aspect ratio, and duration; the node submits the generation request and returns the generated video.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The ByteDance model used to generate the video (default: `"seedance-1-0-pro-fast-251015"`).	COMBO	Yes	`"seedance-1-5-pro-251215"` `"seedance-1-0-pro-250528"` `"seedance-1-0-pro-fast-251015"`
`prompt`	The text prompt used to generate the video.	STRING	Yes	-
`resolution`	The resolution of the output video.	COMBO	Yes	`"480p"` `"720p"` `"1080p"`
`aspect_ratio`	The aspect ratio of the output video.	COMBO	Yes	`"16:9"` `"4:3"` `"1:1"` `"3:4"` `"9:16"` `"21:9"`
`duration`	The duration of the output video in seconds (default: 5).	INT	Yes	3 to 12
`seed`	Seed to use for generation (default: 0).	INT	No	0 to 2147483647
`camera_fixed`	Specifies whether to fix the camera. The platform appends an instruction to fix the camera to your prompt, but does not guarantee the actual effect (default: False).	BOOLEAN	No	-
`watermark`	Whether to add an “AI generated” watermark to the video (default: False).	BOOLEAN	No	-
`generate_audio`	This parameter is ignored for any model except `seedance-1-5-pro-251215` (default: False).	BOOLEAN	No	-

Parameter Constraints:

The prompt parameter must contain at least 1 character after whitespace removal.
The prompt parameter cannot contain the following text parameters: “resolution”, “ratio”, “duration”, “seed”, “camerafixed”, “watermark”.
The node builds the final prompt by appending the selected resolution, aspect_ratio, duration, seed, camera_fixed, and watermark settings to the prompt text.
The duration parameter is limited to values between 3 and 12 seconds. For the seedance-1-5-pro-251215 model, the minimum supported duration is 4 seconds.
The seed parameter accepts values from 0 to 2,147,483,647.
The generate_audio parameter only has an effect when the model is set to seedance-1-5-pro-251215; it is ignored for all other models.
