# Wan2VideoEditApi - ComfyUI Built-in Node Documentation

> Complete documentation for the Wan2VideoEditApi node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The Wan2VideoEditApi node uses the Wan 2.7 model to edit a video based on text instructions, reference images, or style transfer. It processes the input video and generates a new video according to the specified parameters like resolution, duration, and aspect ratio.

## Inputs
