AI-KSK ComfyUI workflow: MiniMax H3 OpenVDN DMD8 4K. The pinned OpenVDN DMD8 distilled path at UHD, with SeedVR2 post upscaling for the final 3840x2160 output. 
 
Main features: 
- MiniMax H3 hybrid FL2VA/Ref2VA INT8 UNET with Qwen3-VL 32B text encoder, video and audio VAEs for native audio generation. 
- Pinned OpenVDN vdn-minimax-h3 branch with the stage_dmd_8nfe distilled sampling stage. 
- SeedVR2 3B FP8 video upscaling with block-swap VRAM optimization, normalized to UHD 3840x2160. 
- Native audio preserved, DLSS 2x frame interpolation (24 to 48 FPS). 
- Fastest 4K option in the pack for prompts that already work on the distilled DMD8 route. 
 
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.
