# WanSoundImageToVideo - ComfyUI Built-in Node Documentation

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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/WanSoundImageToVideo/en.md)

The WanSoundImageToVideo node generates video content from images with optional audio conditioning. It takes positive and negative conditioning prompts along with a VAE model to create video latents, and can incorporate reference images, audio encoding, control videos, and motion references to guide the video generation process.

## Inputs

| Parameter              | Data Type          | Required | Range                 | Description                                                                                      |
| ---------------------- | ------------------ | -------- | --------------------- | ------------------------------------------------------------------------------------------------ |
| `positive`             | CONDITIONING       | Yes      | -                     | Positive conditioning prompts that guide what content should appear in the generated video       |
| `negative`             | CONDITIONING       | Yes      | -                     | Negative conditioning prompts that specify what content should be avoided in the generated video |
| `vae`                  | VAE                | Yes      | -                     | VAE model used for encoding and decoding the video latent representations                        |
| `width`                | INT                | Yes      | 16 to MAX\_RESOLUTION | Width of the output video in pixels (default: 832, must be divisible by 16)                      |
| `height`               | INT                | Yes      | 16 to MAX\_RESOLUTION | Height of the output video in pixels (default: 480, must be divisible by 16)                     |
| `length`               | INT                | Yes      | 1 to MAX\_RESOLUTION  | Number of frames in the generated video (default: 77, must be divisible by 4)                    |
| `batch_size`           | INT                | Yes      | 1 to 4096             | Number of videos to generate simultaneously (default: 1)                                         |
| `audio_encoder_output` | AUDIOENCODEROUTPUT | No       | -                     | Optional audio encoding that can influence the video generation based on sound characteristics   |
| `ref_image`            | IMAGE              | No       | -                     | Optional reference image that provides visual guidance for the video content                     |
| `control_video`        | IMAGE              | No       | -                     | Optional control video that guides the motion and structure of the generated video               |
