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. ## 🔗 Free Trial and Tutorials - [Free Trial 1](<a rel="ugc" href="https://www.runninghub.ai/zh-cn/post/2089489504634093569">https://www.runninghub.ai/zh-cn/post/2089489504634093569</a>) - [Free Trial 2](<a rel="ugc" href="https://www.runninghub.ai/zh-cn/post/2085932029514194946">https://www.runninghub.ai/zh-cn/post/2085932029514194946</a>) - [Bilibili Tutorial 1](<a rel="ugc" href="https://www.bilibili.com/video/BV1tR8u6HEc2/?spm_id_from=333.1387.upload.video_card.click&amp;vd_source=6cbfce8b2fa8b39da3f59cd51cf10652">https://www.bilibili.com/video/BV1tR8u6HEc2/?spm_id_from=333.1387.upload.video_card.click&amp;vd_source=6cbfce8b2fa8b39da3f59cd51cf10652</a>) - [Bilibili Tutorial 2](<a rel="ugc" href="https://www.bilibili.com/video/BV1hrgL6oE2v/?share_source=copy_web&amp;vd_source=5affe0c87cf930412c6282434d4d32d1">https://www.bilibili.com/video/BV1hrgL6oE2v/?share_source=copy_web&amp;vd_source=5affe0c87cf930412c6282434d4d32d1</a>) ## 📝 Notes - **Not** a plain upscaler - **Best for** generation and redraw - **Not** a replacement for video editing </h3>
