## What it is
CorridorKey is a Python-based neural network tool that unmixes green/blue screen footage, reconstructing true foreground color and linear alpha per pixel for realistic composites. It preserves semi-transparent details like hair, motion blur, and translucency that traditional keyers and binary AI roto tools destroy.

## Use cases
- key green screen footage with soft edges
- extract alpha matte from chroma key plates
- remove green spill from composited subjects
- preserve motion blur and hair in a key
- unmix blue screen plates for VFX compositing
- replace manual rotoscoping of green screen shots

## When to choose
- you need physically accurate straight color and linear alpha output
- traditional keyers fail on semi-transparent or motion-blurred edges
- you want to avoid manual rotoscoping and edge matte work
- you work with 4K green or blue screen plates

## When to avoid
- you need a battle-tested production tool - this is a brand new release
- you need blue screen support on Apple MLX backend (green only until the checkpoint ships)
- you want a GUI - use the EZ-CorridorKey companion instead
- you need real-time keying during capture
