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