🔬 How It Works

Processing Pipeline

graph LR
    A[Upload Video] --> B[Manual Mask Editing]
    B --> C[Generate Mask Image]
    C --> D[Upload to R2 Storage]
    D --> E[Submit to ComfyUI]
    E --> F[AI Inpainting]
    F --> G[Download Result]
    G --> H[Store in R2]
    H --> I[Deliver to User]

Technical Workflow

1. Video Upload: User uploads Sora video (supports drag & drop)
2. Mask Creation: Interactive canvas allows precise watermark region marking
3. Mask Generation: Convert marked regions to PNG mask image
4. Cloud Upload: Upload original video and mask to Cloudflare R2
5. ComfyUI Processing:
   • Load video and mask into ComfyUI workflow
   • Apply AI inpainting using U-Net architecture
   • Process frame-by-frame with context awareness
6. Result Delivery: Download processed video and store in R2
7. User Access: Provide download link and preview
