# WanImageToVideoApi - ComfyUI Built-in Node Documentation

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

The Wan Image to Video node generates a video from a single input image and a text prompt. It uses the provided image as the first frame and creates a video sequence based on the description, with options for resolution, duration, audio, and other advanced settings.

## Inputs

| Parameter         | Description                                                                                                                                                                                                            | Data Type | Required | Range                                  |
