MiniMax-H3 NSFW video workflow

The Video Pack runs on MiniMax-H3, the open image-to-video model by MiniMax, packaged for ComfyUI through Comfy-Org on Hugging Face. The pack ships the pruned int8 reference-to-video build, the Qwen3-VL 32B text encoder, separate video and audio VAEs, and the ref2v turbo LoRA. A source image and a prompt produce a clip of 5 to 15 seconds whose soundtrack matches the motion.

Everything installs with one command. Sampler, CFG, and LoRA settings arrive pre-calibrated. Leave them as they ship.

How a clip gets made

  1. The source image becomes the first frame of the clip.
  2. The diffusion model animates it, 24 fps, 5 to 15 seconds.
  3. The audio VAE generates the soundtrack in the same pass, so sound matches motion.
  4. A two-stage quality pipeline renders, then refines the result.

The prompt carries two blocks: one for the picture, one for the sound. Describe one continuous shot in temporal order: what moves, then the lighting and camera, then the matching sounds.

Writing prompts that hold up

  • Describe motion, not appearance. The source image already sets the look.
  • One primary action per clip. Layered actions lower coherence.
  • Do not contradict the source image. The clip starts from it.
  • One continuous action scales better than a sequence of position changes.
