This workflow is the flagship role swap / reference editing route in the MiniMax H3 swap episode. It replaces the character in a reference video with the character defined by a reference image, then runs an independent face refine pass over the generated clip to clean up facial detail and identity stability before the final video is exported.

The inspected graph uses the MiniMax H3 hybrid FL2VA/Ref2VA INT8 base model (minimax_h3_hybrid_fl2va_ref2va_zs05_b25-49_int8.safetensors), Qwen3-VL 32B NVFP4/AWQ text encoding, MiniMax H3 video VAE (INT8 ConvRot) and audio VAE (FP32), and OpenVDN DMD8 execution planning with custom samplers. Depth control comes from Video Depth Anything ViT-S (518x1280 fp16, gray), subject tracking comes from SeC full-clip segmentation with feathered mask compositing, and the swap is driven by the MiniMaxH3ReferenceToVideo control node that combines the Picture 1 identity reference with the single reference video depth composite (768x768, 362-frame setting). Reference audio is encoded through the LTXV audio VAE and the final clip is packaged at a unified 24 FPS with a safe audio channel.

On top of the base swap, the ADDON Face chain detects faces with YuNet (ONNX face detection), crops a 512 AV latent window around the tracked face, re-samples it with a separate minimax_h3_fl2va_int8_convrot model using a low-denoise 12-step schedule (0.45 denoise, dual_clock_euler / native_flow), and stitches the refined crop back into the full frame. The Stitch + Audit node is a diagnostic output and is not part of the final deliverable.

This package is meant for ComfyUI and RunningHub users who want a ready-made character replacement graph with a built-in face correction stage, instead of wiring loaders, encoders, VAEs, depth, segmentation, and face refine nodes by hand. It is especially useful when the base swap works but facial detail or identity drift needs an extra pass.

Main features:

- Character replacement driven by a multi-view Picture 1 identity reference plus reference video depth composite
- Video Depth Anything ViT-S whole-frame depth and SeC full-clip segmentation with feathered compositing
- MiniMax H3 hybrid FL2VA/Ref2VA INT8 base with OpenVDN DMD8 execution planning
- Independent face refine stage: YuNet detection, 512 AV latent crop, low-denoise 12-step re-sample, stitch back
- Face tracking preview and refined crop preview outputs for troubleshooting
- Qwen3-VL 32B NVFP4/AWQ text encoding with MiniMax H3 video and audio VAEs
- Final video packaged at unified 24 FPS with a safe audio channel; dual-instance graph included

Suggested workflow:

Start with the base swap settings from the episode video and keep the same reference image, prompt, duration, and seed when comparing variants. Check the face tracking preview first to confirm the detector locks onto the subject, then review the refined face crop output before judging the final clip. If the face still drifts after the refine pass, improve the reference image quality or the crop window before changing model or sampler settings.

For fair comparisons across the three variants of this episode, run one short test first with identical inputs, then review identity stability, motion consistency, and background drift before scaling up to full-length renders.
