Description

Turn ComfyUI into a professional VFX studio. This high-end pipeline utilizes the latest AI advancements to perform complex video inpainting and character replacement while preserving the original motion dynamics.

This workflow automates the tedious parts of video editing. You don't need to manually draw masks frame-by-frame. Instead, it uses Vision-Language Models to "see" your video, SAM2 to mask the subject perfectly, and Pose Control to ensure the new character moves exactly like the original.

🔥 Key Features:

1. WanVideo 2.2 Powerhouse: Built on the cutting-edge WanVideo 2.2 (14B) model, capable of generating cinema-grade video sequences with superior consistency.
2. Smart Auto-Detection (QwenVL): Forget manual masking. The integrated Qwen Vision-Language model understands natural language (e.g., "man walking in a suit") and automatically detects the subject in your video.
3. Surgical Precision (SAM2): Once detected, Segment Anything Model 2 (SAM2) generates pixel-perfect masks, cleanly separating the subject from the background for seamless inpainting.
4. Motion Locking (Pose Control): Uses ViTPose/DWPose to extract the skeleton and facial landmarks from the source video. The generated character will match the original performance, movement for movement.
5. Relighting & LoRA Stack: Includes nodes for LoRA management and relighting to ensure the new subject blends naturally into the scene's lighting environment.
