# EmptyCosmosLatentVideo - ComfyUI Built-in Node Documentation

> EmptyCosmosLatentVideo creates an empty latent video tensor with the specified dimensions.

EmptyCosmosLatentVideo creates an empty latent video tensor with the 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, increments of 16) | INT       | Yes      | 16 to MAX\_RESOLUTION |
| `height`     | The height of the latent video in pixels (default: 704, increments of 16) | INT       | Yes      | 16 to MAX\_RESOLUTION |
| `length`     | The number of frames in the latent video (default: 121, increments of 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             |

Note: The latent tensor is spatially downsampled by a factor of 8 in both height and width, and contains 16 channels. The number of latent temporal frames is calculated as `((length - 1) // 8) + 1`.

## Outputs

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