This node adjusts the first few frames of a video latent to make them look more like the frames that come after. It calculates the average and variation from a set of reference frames later in the video and applies those same characteristics to the starting frames. This helps create a smoother and more consistent visual transition at the beginning of a video.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| --- | --- | --- | --- | --- |
| `latent` | The video latent representation to process. | LATENT | Yes | - |
| `start_frame_count` | Number of latent frames to normalize, counted from the start (default: 4). | INT | Yes | 1 to 16384 (max resolution) |
| `reference_frame_count` | Number of latent frames after the start frames to use as reference (default: 5). | INT | Yes | 1 to 16384 (max resolution) |

**Note:** The `reference_frame_count` is automatically limited to the number of frames available after the starting frames. If the video latent is only 1 frame long, no normalization is performed and the original latent is returned unchanged.

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `latent` | The processed video latent with the starting frames normalized. | LATENT |
