# Veo3VideoGenerationNode - ComfyUI Built-in Node Documentation

> Complete documentation for the Veo3VideoGenerationNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

Generates videos from text prompts using Google's Veo 3 API. This node supports multiple Veo 3 models, including fast and lite variants, and allows you to specify video resolution, duration, and audio generation.

## Inputs

**Note:** The `enhance_prompt` parameter is deprecated and its value is ignored. The node always enhances the prompt internally. Additionally, the `resolution` parameter is only applied when using a veo-3.1 model; it is ignored for veo-3.0 models. If you select "4k" resolution with a veo-3.1-lite or veo-3.0 model, the node will raise an error.

## Outputs

| Output Name | Description              | Data Type |
| ----------- | ------------------------ | --------- |
| `output`    | The generated video file | VIDEO     |
