# EmptyLTXVLatentVideo - ComfyUI Built-in Node Documentation

> The EmptyLTXVLatentVideo node creates an empty (zero-filled) latent video tensor using the width, height, length, and batch size you specify.

The EmptyLTXVLatentVideo node creates an empty (zero-filled) latent video tensor using the width, height, length, and batch size you specify. It provides a blank starting point for LTXV video generation workflows, with the latent dimensions automatically compressed relative to the requested video size.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `width` | The width of the latent video tensor (default: 768, step: 32) | INT | Yes | 64 to MAX\_RESOLUTION |
| `height` | The height of the latent video tensor (default: 512, step: 32) | INT | Yes | 64 to MAX\_RESOLUTION |
| `length` | The number of frames in the latent video (default: 97, step: 8) | INT | Yes | 1 to MAX\_RESOLUTION |
| `batch_size` | The number of latent videos to generate in a batch (default: 1) | INT | Yes | 1 to 4096 |

Note: The latent video is compressed compared to the requested dimensions: the spatial dimensions (width and height) are divided by 32, and the frame count (length) is divided by 8 and rounded up to the nearest whole number. The step values for width, height, and length help keep these divisions even.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `samples` | The generated empty latent tensor with zero values in the specified dimensions, along with a spatial downscale ratio of 32 | LATENT |
