# NormalizeVideoLatentStart - ComfyUI Built-in Node Documentation

> This node adjusts the first few frames of a video latent to make them look more like the frames that come after.

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 reduce differences between the starting frames and the rest of the video, creating a smoother and more consistent transition.

## 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 frames are taken starting right after the `start_frame_count` frames. If there are fewer frames available than `reference_frame_count` requests, the node uses however many are available (at most one less than the total frame count of the latent). If the video latent has only 1 frame, 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    |
