# 🌟 MiniMax H3 Dual-Stage Sampling Workflow

> **Dual-Stage Sampling | Dual-Model Upscaling**
> Pass 1 builds the frame. Pass 2 repairs the details.

This is a **MiniMax H3** workflow built around two-stage sampling. The point is not to finish everything in one pass, but to split output quality into two clear stages.

## ✨ What It Does

- Fixes **noise**, **broken details**, **soft edges**, and **unstable consistency**
- Pass 1 handles **motion**, **composition**, and **overall fitting**
- Pass 2 uses **W4A8** with **low denoise** for detail repair and clarity

Pass 1 gets the frame to stand up. Pass 2 only repairs it, so the final result can reach higher resolution and cleaner consistency on the same hardware.
