# HunyuanVideo15SuperResolution - ComfyUI Built-in Node Documentation

> The HunyuanVideo15SuperResolution node prepares conditioning data for a video super-resolution process.

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 | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `positive` | The positive conditioning input to be modified with latent and augmentation data. | CONDITIONING | Yes | N/A |
| `negative` | The negative conditioning input to be modified with latent and augmentation data. | CONDITIONING | Yes | N/A |
| `vae` | The VAE used to encode the optional `start_image`. Required if `start_image` is provided. | VAE | No | N/A |
| `start_image` | An optional starting image to guide the super-resolution. If provided, it is upscaled and encoded into the conditioning latent. | IMAGE | No | N/A |
| `clip_vision_output` | Optional CLIP vision embeddings to add to the conditioning. | CLIP\_VISION\_OUTPUT | No | N/A |
| `latent` | The input latent video representation that is incorporated into the conditioning. | LATENT | Yes | N/A |
| `noise_augmentation` | The strength of noise augmentation to apply to the conditioning (default: 0.70). This is an advanced parameter; a value is always supplied by the default. | FLOAT | Yes | 0.0 - 1.0 (step 0.01) |

**Note:** If you provide a `start_image`, you must also connect a `vae` so it can be encoded. The `start_image` is automatically upscaled to 16 times the spatial dimensions (width and height) of the input `latent`, then encoded and placed into the conditioning latent. Only the RGB channels of the `start_image` are used for encoding.

## Outputs

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