How to use:
  1. Install the custom nodes above and restart ComfyUI.
  2. Download the model files into the folders listed.
  3. Drag freakyjolly-minimax-h3-r2v-turbo6-1080p72.json onto the canvas.
  4. Pick your reference image in "CHANGE ME: one 16:9 reference image" and edit the prompt in MiniMax H3 Reference to Video (<Picture 1> = first reference).
  5. Queue. Two MP4s are saved in ComfyUI/output/video/: MiniMax_H3_r2v_08mp_raw24* and MiniMax_H3_r2v_08mp_upscaled_1080p72*.

Notes:
  - Sage Attention is "auto" in Patch Sage Attention KJ; set it to "disabled" if SageAttention is not installed.
  - The finishing branch (RIFE x3 + NomosUni 2x + 1920x1080) runs in the same job and is heavy; bypass it if you only need the raw 24 fps clip.
  - ClipProjLoader device is cuda:0.

Model weights are not included. Each model keeps its own licence; check the model page before commercial use.
