# MiniMax H3 Latent Upscale With Model - ComfyUI Built-in Node Documentation

> MiniMax H3 Latent Upscale With Model resizes the video part of a MiniMax H3 latent to a target width and height with a latent upscale model.

MiniMax H3 Latent Upscale With Model resizes the video part of a MiniMax H3 latent to a target width and height with a latent upscale model. The audio latent rides along untouched, so the clip keeps its sound, and no re-sampling is needed. Use it after MiniMax H3 sampling and before the H3 VAE decode when the clip should come out larger.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `model` | Latent upscale model, usually loaded with Load Latent Upscale Model. It has to be a MiniMax H3 3D-conv latent upscaler. | LATENT\_UPSCALE\_MODEL | Yes | - |
| `samples` | MiniMax H3 latent to resize. A nested latent keeps its audio part as it is. | LATENT | Yes | - |
| `width` | Target video width in pixels. The latent is resized to `width / 16` columns, so the value is rounded down to a multiple of 16. (default: 2560) | INT | Yes | 32 to 16384 (step 32) |
| `height` | Target video height in pixels, also rounded down to a multiple of 16. (default: 1440) | INT | Yes | 32 to 16384 (step 32) |

When the requested size already matches the latent, the input latent is returned unchanged. A resized latent carries no `noise_mask`, so a partially masked latent loses its mask. The network runs its 3D convolutions in temporal slabs, which keeps memory use on long clips close to that of a single slab.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `LATENT` | The resized latent, ready for the H3 VAE decode. | LATENT |
