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

💬 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.
