# EmptyCosmosLatentVideo - ComfyUI Built-in Node Documentation

> Complete documentation for the EmptyCosmosLatentVideo node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The EmptyCosmosLatentVideo node creates an empty latent video tensor with specified dimensions. It generates a zero-filled latent representation that can be used as a starting point for video generation workflows, with configurable width, height, length, and batch size parameters.

## Inputs

| Parameter    | Description                                                                      | Data Type | Required | Range                 |
| ------------ | -------------------------------------------------------------------------------- | --------- | -------- | --------------------- |
| `width`      | The width of the latent video in pixels (default: 1280, must be divisible by 16) | INT       | Yes      | 16 to MAX\_RESOLUTION |
| `height`     | The height of the latent video in pixels (default: 704, must be divisible by 16) | INT       | Yes      | 16 to MAX\_RESOLUTION |
| `length`     | The number of frames in the latent video (default: 121, must be divisible by 8)  | INT       | Yes      | 1 to MAX\_RESOLUTION  |
| `batch_size` | The number of latent videos to generate in a batch (default: 1)                  | INT       | No       | 1 to 4096             |

## Outputs

| Output Name | Description                                              | Data Type |
| ----------- | -------------------------------------------------------- | --------- |
| `samples`   | The generated empty latent video tensor with zero values | LATENT    |
