AI-KSK ComfyUI workflow: MiniMax H3 Sigma Dual-Pass 4K. Maximum-fidelity tier of the pack: dual-pass Sigma reinforcement sampling, 3D latent upscaling, and SeedVR2 post upscaling to UHD 3840x2160. 
 
Main features: 
- MiniMax H3 hybrid FL2VA/Ref2VA INT8 UNET with Qwen3-VL 32B text encoder, video and audio VAEs for native audio generation. 
- Dual-pass Sigma reinforcement: 0.5 MP first pass followed by a second pass with the 768p Ref2V Turbo 8-step LoRA at full strength and 10-step Euler sampling. 
- MiniMax H3 3D latent upscaler (FP16, 2x multiplier) between passes for higher internal detail. 
- SeedVR2 3B FP8 video upscaling, normalized to UHD 3840x2160. 
- Native audio preserved, DLSS 2x frame interpolation (24 to 48 FPS). 
- The longest render in the 9-workflow pack; reserve it for final cuts and hero shots. 
 
Suggested workflow: 
1. Import the JSON into ComfyUI and install the model files and custom nodes referenced by the workflow. 
2. Provide the required text, image, or video inputs for the selected path. 
3. Adjust resolution, steps, denoise, and prompt controls, then run the connected SaveVideo output.
