# CosmosImageToVideoLatent - ComfyUI Built-in Node Documentation

> Complete documentation for the CosmosImageToVideoLatent 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/CosmosImageToVideoLatent/en.md)

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

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