GitHub - nikopueringer/CorridorKey: Perfect Green Screen Keys
Added Mar 9
Article: Very Positive
CorridorKey is a neural network-based tool designed to create high-fidelity green screen extractions by reconstructing true foreground colors and linear alpha channels. It excels at preserving difficult details like motion blur and hair that traditional keying methods often destroy. While it requires a high-end GPU and a rough initial mask, it provides professional VFX-standard outputs for seamless compositing.
Key Points
- Uses neural networks to perform physically accurate 'unmixing' of foreground colors and alpha channels.
- Preserves complex edge details such as motion blur, out-of-focus areas, and fine hair.
- Requires a coarse alpha hint (rough mask) to guide the high-fidelity extraction process.
- Supports professional VFX standards, including 16/32-bit Linear float EXR outputs for Nuke, Fusion, and Resolve.
- Demands significant hardware resources, specifically recommending a GPU with 24GB of VRAM or more.
