# CosmosImageToVideoLatent - ComfyUI Built-in Node Documentation

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

The CosmosImageToVideoLatent node creates video latent representations from input images. It generates a blank video latent and optionally encodes start and/or end images into the beginning and/or end frames of the video sequence. When images are provided, it also creates corresponding noise masks to indicate which parts of the latent should be preserved during generation.

## Inputs

| Parameter     | Description                                                     | Data Type | Required | Range                 |
| ------------- | --------------------------------------------------------------- | --------- | -------- | --------------------- |
| `vae`         | The VAE model used for encoding images into latent space        | VAE       | Yes      | -                     |
| `width`       | The width of the output video in pixels (default: 1280)         | INT       | Yes      | 16 to MAX\_RESOLUTION |
| `height`      | The height of the output video in pixels (default: 704)         | INT       | Yes      | 16 to MAX\_RESOLUTION |
| `length`      | The number of frames in the video sequence (default: 121)       | INT       | Yes      | 1 to MAX\_RESOLUTION  |
| `batch_size`  | The number of latent batches to generate (default: 1)           | INT       | Yes      | 1 to 4096             |
| `start_image` | Optional image to encode at the beginning of the video sequence | IMAGE     | No       | -                     |
| `end_image`   | Optional image to encode at the end of the video sequence       | IMAGE     | No       | -                     |

**Note:** When neither `start_image` nor `end_image` are provided, the node returns a blank latent without any noise mask. When either image is provided, the corresponding sections of the latent are encoded and masked accordingly.

## Outputs

| Output Name | Description                                                                                          | Data Type |
| ----------- | ---------------------------------------------------------------------------------------------------- | --------- |
| `latent`    | The generated video latent representation with optional encoded images and corresponding noise masks | LATENT    |
