# WanFunInpaintToVideo - ComfyUI Built-in Node Documentation

> The WanFunInpaintToVideo node prepares conditioning and latent data for inpainting-style video generation, using an optional start image and end image to guide the result.

The WanFunInpaintToVideo node prepares conditioning and latent data for inpainting-style video generation, using an optional start image and end image to guide the result. It works by passing the supplied conditioning, VAE, and image frames through the same logic used for first-and-last-frame video generation, and returns updated conditioning plus an empty latent for sampling.

## Inputs

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