VeoVideoGenerationNode - ComfyUI Built-in Node Documentation

Generates videos from text prompts using Google’s Veo API. This node can create videos from text descriptions and optional image inputs, with control over parameters like aspect ratio, duration, and more.

Inputs

Parameter	Description	Data Type	Required	Range
`prompt`	Text description of the video (default: empty)	STRING	Yes	-
`aspect_ratio`	Aspect ratio of the output video (default: “16:9”)	COMBO	Yes	”16:9" "9:16”
`negative_prompt`	Negative text prompt to guide what to avoid in the video (default: empty)	STRING	No	-
`duration_seconds`	Duration of the output video in seconds (default: 5)	INT	No	5-8
`enhance_prompt`	Whether to enhance the prompt with AI assistance (default: True). This is an advanced parameter.	BOOLEAN	No	-
`person_generation`	Whether to allow generating people in the video (default: “ALLOW”). This is an advanced parameter.	COMBO	No	”ALLOW" "BLOCK”
`seed`	Seed for video generation (0 for random) (default: 0). This is an advanced parameter.	INT	No	0-4294967295
`image`	Optional reference image to guide video generation	IMAGE	No	-
`model`	Veo model to use for video generation (default: “veo-2.0-generate-001”)	COMBO	No	”veo-2.0-generate-001" "veo-3.1-generate" "veo-3.1-fast-generate" "veo-3.1-lite" "veo-3.0-generate-001" "veo-3.0-fast-generate-001”

Note: The generate_audio parameter is only available for Veo 3.0 and Veo 3.1 models and is automatically handled by the node based on the selected model. When using Veo 3.0 or Veo 3.1 models, the enhance_prompt parameter is forced to True.
