How to use:
  1. Install the custom nodes above and restart ComfyUI.
  2. Download the model files into the folders listed.
  3. Drag MiniMax_H3_R2V_Prompt_Template.json onto the canvas.
  4. Pick your character image in the "CHANGE ME" Load Image node. It becomes <Picture 1>.
  5. The prompt node is pre-filled with the rewritten six-section prompt from the article (subject_definitions, summary, retention_analysis, detailed_description, overall_soundscape, non_diegetic_music). Replace the text in each section with your own and queue.

Notes:
  - Duration is 5 s (124 frames = 5.17 s effective). Keep any timed events and cut times inside that length.
  - This is the same reference-to-video Turbo graph as my R2V article, with only the prompt, duration and Load Image title changed. Bypass the RIFE/upscale branch if you only need the raw 24 fps clip.

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