This is not just a basic Video-to-Video workflow. It features an automated First Frame Pre-Processing Pipeline that performs a head, face, body, and clothing swap on the extracted first frame of your source video before feeding it into the MiniMax H3 Reference-to-Video engine.

It allows you to seamlessly transfer motion, performance, and camera movement from a reference video while completely customizing the subject’s identity and outfit!

🔥 Key Features

  • Auto First-Frame Extraction & Swap: Automatically extracts the initial frame of your selected video duration and swaps the head/face/clothing with your uploaded image (Picture 1) using SAM 3.1 & Flux Klein.

  • Dual Operating Modes: Easily toggle between full character pre-processing and direct video-to-video style transfer.

⚙️ How to Use

🟢 Mode A: Full Face, Head & Clothing Swap (Default)

  1. Load Video: Upload your reference motion video into LoadVideoUI and adjust the start/end time. (Make sure the subject's face is clearly visible in the first frame of your selection).

  2. Upload Target Image: Place your desired character/outfit image into Picture 1.

  3. Switch Node: Set the Image Switch (JPS) node to Select 2 (Extracted Frame).

  4. Run the workflow!

🔵 Mode B: Direct Video-to-Video (No Pre-Swap)

  1. Upload your reference video into LoadVideoUI.

  2. Upload your source image into Picture 1.

  3. Bypass Swap Group: Enable bypass on the FACE CLOTHE SWAP group using the Fast Groups Bypasser.

  4. Switch Node: Set the Image Switch (JPS) node to Select 1 (Picture 1).

  5. Run the workflow!

💬 Tips & Troubleshooting

  • Face Visibility: The pre-processing pipeline targets frame #1 of your selected video range. Always ensure the face is visible at the very start frame for optimal SAM 3.1 segmentation.

  • Do not use acceleration. You get bad results.

  • Custom Prompts: You can adjust the Prompt node to fine-tune the retention vs. replacement ratios if needed.
