# HunyuanVideo15SuperResolution - ComfyUI Built-in Node Documentation

> Complete documentation for the HunyuanVideo15SuperResolution 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/HunyuanVideo15SuperResolution/en.md)

The HunyuanVideo15SuperResolution node prepares conditioning data for a video super-resolution process. It takes a latent representation of a video and, optionally, a starting image, and packages them along with noise augmentation and CLIP vision data into a format that can be used by a model to generate a higher-resolution output.

## Inputs

| Parameter            | Data Type            | Required | Range     | Description                                                                                                                          |
| -------------------- | -------------------- | -------- | --------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| `positive`           | CONDITIONING         | Yes      | N/A       | The positive conditioning input to be modified with latent and augmentation data.                                                    |
| `negative`           | CONDITIONING         | Yes      | N/A       | The negative conditioning input to be modified with latent and augmentation data.                                                    |
| `vae`                | VAE                  | No       | N/A       | The VAE used to encode the optional `start_image`. Required if `start_image` is provided.                                            |
| `start_image`        | IMAGE                | No       | N/A       | An optional starting image to guide the super-resolution. If provided, it will be upscaled and encoded into the conditioning latent. |
| `clip_vision_output` | CLIP\_VISION\_OUTPUT | No       | N/A       | Optional CLIP vision embeddings to add to the conditioning.                                                                          |
| `latent`             | LATENT               | Yes      | N/A       | The input latent video representation that will be incorporated into the conditioning.                                               |
| `noise_augmentation` | FLOAT                | No       | 0.0 - 1.0 | The strength of noise augmentation to apply to the conditioning (default: 0.70).                                                     |

**Note:** If you provide a `start_image`, you must also connect a `vae` for it to be encoded. The `start_image` will be automatically upscaled to match the dimensions implied by the input `latent`.

## Outputs

| Output Name | Data Type    | Description                                                                                                                    |
| ----------- | ------------ | ------------------------------------------------------------------------------------------------------------------------------ |
| `positive`  | CONDITIONING | The modified positive conditioning, now containing the concatenated latent, noise augmentation, and optional CLIP vision data. |
| `negative`  | CONDITIONING | The modified negative conditioning, now containing the concatenated latent, noise augmentation, and optional CLIP vision data. |
| `latent`    | LATENT       | The input latent is passed through unchanged.                                                                                  |
