# EmptyLTXVLatentVideo - ComfyUI Built-in Node Documentation

> The EmptyLTXVLatentVideo node creates an empty latent tensor for video processing.

The EmptyLTXVLatentVideo node creates an empty latent tensor for video processing. It generates a blank starting point with the specified width, height, length, and batch size, which can be used as an input for video generation workflows. The node produces a zero-filled latent representation whose spatial dimensions are 32 times smaller than the configured width and height, and whose frame count is compressed by a factor of 8.

## 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 input 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    |
