# EmptyMochiLatentVideo - ComfyUI Built-in Node Documentation

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

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/EmptyMochiLatentVideo/en.md)

The EmptyMochiLatentVideo 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. The node allows you to define the width, height, length, and batch size for the latent video tensor.

## Inputs

| Parameter    | Data Type | Required | Range                 | Description                                                                      |
| ------------ | --------- | -------- | --------------------- | -------------------------------------------------------------------------------- |
| `width`      | INT       | Yes      | 16 to MAX\_RESOLUTION | The width of the latent video in pixels (default: 848, must be divisible by 16)  |
| `height`     | INT       | Yes      | 16 to MAX\_RESOLUTION | The height of the latent video in pixels (default: 480, must be divisible by 16) |
| `length`     | INT       | Yes      | 7 to MAX\_RESOLUTION  | The number of frames in the latent video (default: 25)                           |
| `batch_size` | INT       | No       | 1 to 4096             | The number of latent videos to generate in a batch (default: 1)                  |

**Note:** The actual latent dimensions are calculated as width/8 and height/8, and the temporal dimension is calculated as ((length - 1) // 6) + 1.

## Outputs

| Output Name | Data Type | Description                                                                      |
| ----------- | --------- | -------------------------------------------------------------------------------- |
| `samples`   | LATENT    | An empty latent video tensor with the specified dimensions, containing all zeros |
