# EmptyARVideoLatent - ComfyUI Built-in Node Documentation

> Documentation for EmptyARVideoLatent node.

## Overview

The EmptyARVideoLatent node creates a blank, empty latent representation for video generation. It is used to initialize a video generation process by providing a tensor of zeros with the specified dimensions, aspect ratio, and length.

## Inputs

| Parameter    | Description                                                     | Data Type | Required | Range                 |
| ------------ | --------------------------------------------------------------- | --------- | -------- | --------------------- |
| `width`      | The width of the video frames in pixels (default: 832)          | INT       | Yes      | 16 to 8192 (step: 16) |
| `height`     | The height of the video frames in pixels (default: 480)         | INT       | Yes      | 16 to 8192 (step: 16) |
| `length`     | The number of frames in the video (default: 81)                 | INT       | Yes      | 1 to 1024 (step: 4)   |
| `batch_size` | The number of videos to generate in a single batch (default: 1) | INT       | Yes      | 1 to 64               |

## Outputs

| Output Name | Description                                                                                                                                                                                                                                                                                                        | Data Type |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | --------- |
| `LATENT`    | A latent tensor filled with zeros, representing an empty video latent space with the specified dimensions, length, and batch size. The tensor shape is \[batch\_size, 16, lat\_t, height/8, width/8], where lat\_t = ((length - 1) // 4) + 1 is the number of latent time steps derived from the requested length. | LATENT    |
