# LTXVLatentUpsampler - ComfyUI Built-in Node Documentation

> The LTXVLatentUpsampler node increases the spatial resolution of a video latent representation by a factor of two.

The LTXVLatentUpsampler node increases the spatial resolution of a video latent representation by a factor of two. It uses a dedicated upscale model to process the latent data, which is first un-normalized and then re-normalized using the provided VAE's channel statistics. This node is designed for video workflows within the latent space.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `samples` | The input latent representation of the video to be upscaled. | LATENT | Yes | |
| `upscale_model` | The loaded model used to perform the 2x upscaling on the latent data. | LATENT\_UPSCALE\_MODEL | Yes | |
| `vae` | The VAE model used to un-normalize the input latents before upscaling and to normalize the output latents afterwards. | VAE | Yes | |

Note: This node is marked as experimental in ComfyUI.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `LATENT` | The upscaled latent representation, with spatial dimensions doubled compared to the input. The output latent has the same batch size, number of channels, and temporal length as the input. The `noise_mask` from the input, if present, is removed from the output. | LATENT |
