 "page_title": "How to refine small faces in a MiniMax H3 video with Comfy UI H3 Face Refine",
 "summary": "Track each face per frame, crop to it, re-generate it with H3, and stitch it back into the clip.",
 "who": "A video creator whose MiniMax H3 clip has smeared faces because the head fills only a small part of the frame.",
 "problem": "H3 renders faces poorly when the head is a small fraction of the frame, and that stays true at 720p and above.",
 "outcome": "A composited video where the small face is re-generated from a normalized crop and the rest of the frame keeps its original pixels.",
 "steps": [
  "Run `git clone https://github.com/Carasibana/ComfyUI-H3-FaceRefine.git` inside ComfyUI/custom_nodes/.",
  "Restart ComfyUI and confirm the nodes appear under MiniMax H3/Face Refine.",
  "Place face_yolov8m.pt in models/ultralytics/bbox/, and the H3 diffusion model, Qwen3-VL text encoder, and VAEs in their folders.",
  "Load your clip, choose the subject with the select setting, and connect it to H3 Face Track + Crop.",
  "Send the crop through the H3 node, composite the result back, and save the video with a node such as VHS_VideoCombine."
 ],
 "agent_prompt": "Using the repo Carasibana/ComfyUI-H3-FaceRefine, build a ComfyUI graph that refines the small face of <subject description> in <video path> and writes a composited video to <output path>. Verify that the tracker report shows the subject found on most frames and lists any lost frame ranges.",
