# MiniMaxH3SigmaShift - ComfyUI Built-in Node Documentation

> Complete documentation for the MiniMaxH3SigmaShift node in ComfyUI. Learn its inputs, outputs, parameters and usage.

Sets the video and audio flow shift values for a MiniMax H3 model. The video shift controls the sampler's sigma schedule, and both shift values are passed to the model's internal transformer, which uses them to derive the audio schedule from the shared base grid.

## Inputs

| Parameter     | Description                                                                                                | Data Type | Required | Range         |
| ------------- | ---------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------- |
| `model`       | The model to apply the sigma shift patch to. The node clones the model, so the original remains unchanged. | MODEL     | Yes      | -             |
| `shift_video` | The video flow shift value. It drives the sampler's sigma schedule. Default: 12.0.                         | FLOAT     | Yes      | 0.01 to 100.0 |
| `shift_audio` | The audio flow shift value. It is used by the model to derive the audio schedule. Default: 3.0.            | FLOAT     | Yes      | 0.01 to 100.0 |

## Outputs

| Output Name | Description                                                             | Data Type |
| ----------- | ----------------------------------------------------------------------- | --------- |
| `MODEL`     | The cloned model with the video and audio sigma shift settings applied. | MODEL     |
