ByteDance2TextToVideoNode - ComfyUI Built-in Node Documentation

This node generates a video from a text prompt using ByteDance’s Seedance 2.5 or 2.0 models.

This node generates a video from a text prompt using ByteDance’s Seedance 2.5 or 2.0 models. It sends the prompt to the selected model, waits for the video to finish processing, and returns the resulting video file.

Inputs

Common Inputs

Parameter	Description	Data Type	Required	Range
model	The Seedance model to use for video generation. Seedance 2.5 is the newest model, supporting videos up to 30 seconds and mp4/mov output; Seedance 2.0 is for maximum quality and 4k; Seedance 2.0 Fast is for speed optimization; Seedance 2.0 Mini is for the fastest, lowest-cost generation. Selecting a model reveals additional inputs for the prompt, resolution, aspect ratio, duration, and audio generation.	DYNAMIC_COMBO	Yes	"Seedance 2.5" "Seedance 2.0" "Seedance 2.0 Fast" "Seedance 2.0 Mini"
seed	Controls whether the node should re-run; results are non-deterministic regardless of seed. (default: 0)	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

Seedance 2.5 Inputs

Parameter	Description	Data Type	Required	Range
prompt	Text prompt for video generation. Put spoken lines in double quotes to steer the generated dialogue.	STRING	Yes	—
resolution	Resolution of the output video. (default: "720p")	COMBO	Yes	"480p" "720p" "1080p"
ratio	Aspect ratio of the output video. (default: "16:9")	COMBO	Yes	"16:9" "4:3" "1:1" "3:4" "9:16" "21:9" "adaptive"
duration	Duration of the output video in seconds. (default: 5)	INT	Yes	4 to 30
generate_audio	Enable audio generation for the output video. (default: True)	BOOLEAN	Yes	True / False
output_format	Container format of the output video. (default: "mp4")	COMBO	Yes	"mp4"

Seedance 2.0 Inputs

Parameter	Description	Data Type	Required	Range
prompt	Text prompt for video generation.	STRING	Yes	—
resolution	Resolution of the output video.	COMBO	Yes	"480p" "720p" "1080p" "4k"
ratio	Aspect ratio of the output video. (default: "16:9")	COMBO	Yes	"16:9" "4:3" "1:1" "3:4" "9:16" "21:9" "adaptive"
duration	Duration of the output video in seconds. (default: 7)	INT	Yes	4 to 15
generate_audio	Enable audio generation for the output video. (default: True)	BOOLEAN	Yes	True / False

Seedance 2.0 Fast and Seedance 2.0 Mini Inputs

Shared by Seedance 2.0 Fast and Seedance 2.0 Mini; both models expose the same parameters.

Parameter	Description	Data Type	Required	Range
prompt	Text prompt for video generation.	STRING	Yes	—
resolution	Resolution of the output video.	COMBO	Yes	"480p" "720p"
ratio	Aspect ratio of the output video. (default: "16:9")	COMBO	Yes	"16:9" "4:3" "1:1" "3:4" "9:16" "21:9" "adaptive"
duration	Duration of the output video in seconds. (default: 7)	INT	Yes	4 to 15
generate_audio	Enable audio generation for the output video. (default: True)	BOOLEAN	Yes	True / False

Note: The model selector is dynamic; the inputs shown under each model section appear when that model is selected. The prompt must be at least 1 character long after removing whitespace. Resolution and duration limits depend on the selected model: Seedance 2.5 supports 480p/720p/1080p and 4 to 30 seconds, Seedance 2.0 supports 480p/720p/1080p/4k and 4 to 15 seconds, and Seedance 2.0 Fast and Seedance 2.0 Mini support only 480p/720p and 4 to 15 seconds. The seed value only controls whether the node re-runs; it does not make results deterministic.

Outputs

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