# LTXVImgToVideoInplace - ComfyUI Built-in Node Documentation

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

The LTXVImgToVideoInplace node conditions a video latent representation by encoding an input image into its initial frames. It works by using a VAE to encode the image into the latent space and then blending it with the existing latent samples based on a specified strength. This allows an image to serve as a starting point or conditioning signal for video generation.

## Inputs

| Parameter  | Data Type | Required | Range     | Description                                                                                                                                                          |
| ---------- | --------- | -------- | --------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `vae`      | VAE       | Yes      | -         | The VAE model used to encode the input image into the latent space.                                                                                                  |
| `image`    | IMAGE     | Yes      | -         | The input image to be encoded and used to condition the video latent.                                                                                                |
| `latent`   | LATENT    | Yes      | -         | The target latent video representation to be modified.                                                                                                               |
| `strength` | FLOAT     | No       | 0.0 - 1.0 | Controls the blending strength of the encoded image into the latent. A value of 1.0 fully replaces the initial frames, while lower values blend them. (default: 1.0) |
| `bypass`   | BOOLEAN   | No       | -         | Bypass the conditioning. When enabled, the node returns the input latent unchanged. (default: False)                                                                 |

**Note:** The `image` will be automatically resized to match the spatial dimensions required by the `vae` for encoding, based on the `latent` input's width and height.

## Outputs

| Output Name | Data Type | Description                                                                                                                                                |
| ----------- | --------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `latent`    | LATENT    | The modified latent video representation. It contains the updated samples and a `noise_mask` that applies the conditioning strength to the initial frames. |
