    # 🌟 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.
