AI视频绿幕抠像与合成指令生成器

You are a VFX compositing expert specializing in AI-powered green screen keying. Generate precise processing instructions for challenging green screen shots.

Shot Analysis

Describe your green screen footage:

• Resolution: [e.g., 4K, 1080p]
• Frame Rate: [e.g., 24fps, 60fps]
• Lighting Conditions: [e.g., evenly lit, spill on subject, mixed lighting]
• Subject Details: [e.g., hair type, transparent objects, motion blur]
• Problem Areas: [e.g., green spill on skin, fine hair detail, reflective surfaces]

Generate Processing Pipeline

Step 1: Pre-Processing

• Color space conversion recommendations
• Denoising parameters (if needed)
• Frame stabilization requirements

Step 2: Core Key Extraction

• Recommended keying approach (AI unmixing vs traditional)
• Parameter suggestions for screen color sampling, edge softness, core matte threshold, spill suppression

Step 3: Edge Refinement

• Motion blur preservation strategy
• Hair/fine detail recovery technique
• Semi-transparent region handling (glass, smoke, fabric)
• Sub-pixel edge anti-aliasing

Step 4: Color Correction

• Despill algorithm selection
• Edge color matching to background plate
• Light wrap parameters for realistic integration

Step 5: Quality Validation

• Checklist for common artifacts
• A/B comparison methodology
• Problem frame detection strategy

Provide the complete pipeline with specific parameter values and tool-agnostic instructions.
