AI-KSK ComfyUI workflow: MiniMax H3 SelfLift 4K UHD. The SelfLift generation chain with SeedVR2 post upscaling to UHD 3840x2160, the standard final-delivery tier of the pack.

Main features:
- MiniMax H3 hybrid FL2VA/Ref2VA INT8 UNET with Qwen3-VL 32B text encoder, video and audio VAEs for native audio generation.
- SelfLift 3D latent refinement with the MiniMax H3 latent upscaler and FL2V Turbo 4-step LoRA at 0.65 strength, 8-step Euler sampling.
- SeedVR2 3B FP8 video upscaling with block-swap VRAM optimization, normalized to UHD 3840x2160.
- Native audio preserved through the video/audio VAE decode, DLSS 2x frame interpolation (24 to 48 FPS).
- Run the 768P preview tier first with the same prompt, then promote the approved result to this 4K chain.

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.
