Vidu4ImageToVideoNode - ComfyUI Built-in Node Documentation - ComfyUI

Generate a video from a start frame and an optional prompt with a Vidu Q4 model. The output keeps the aspect ratio of the input image. Selecting a model reveals the parameters specific to that model.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	Start frame of the generated video. Aspect ratio must be between 1:5 and 5:1.	IMAGE	Yes	N/A
`model`	Model to use for video generation. Selecting a model reveals the parameters specific to it: `prompt`, `resolution`, `duration`, `audio`, and `seed`.	DYNAMIC_COMBO	Yes	`"Vidu Q4 Preview"`
`prompt`	An optional text prompt for video generation, up to 5000 characters (default: empty).	STRING	Yes	Any text
`resolution`	Resolution of the output video (default: `"720p"`).	COMBO	Yes	`"540p"` `"720p"` `"1080p"` `"2K"` `"4K"`
`duration`	Duration of the output video in seconds (default: 5).	INT	Yes	3 to 16
`audio`	When enabled, outputs video with sound, including dialogue and sound effects (default: True).	BOOLEAN	Yes	`True` `False`
`seed`	Seed controls whether the node should re-run; results are non-deterministic regardless of seed. This parameter has “control after generate” functionality (default: 42).	INT	Yes	1 to 2147483647

Note: The aspect ratio of image must stay between 1:5 and 5:1, and the prompt cannot exceed 5000 characters. The result keeps the aspect ratio of the input image, so the output size follows the resolution setting only within that ratio.

Outputs

`VIDEO`	The generated video file.	VIDEO
