EZ-CorridorKey
What it is
EZ-CorridorKey is a free desktop interface for CorridorKey, an AI chroma keyer that separates foreground from background. It works with green and blue screens and detects which color was used. GVM and BiRefNet generate alpha automatically, while MatAnyone2 and VideoMaMa offer paint-and-track control. A dual viewer can show source footage and alpha or composite views, with an A/B wipe, pan and zoom, channel switching, and live despill, refine, and despeckle controls. A queue processes clips in sequence and includes progress updates, sound cues, recent projects, and session saving. Export formats include EXR and PNG sequences, ProRes 4444, and VP9 with alpha, preserving bit depth. Footage and project files stay on the user's machine, with no accounts, telemetry, or cloud processing; the app does check GitHub for updates at launch. It supports Windows, macOS, and Linux, with Docker instructions for Linux servers or remote GPUs. Apple Silicon Macs from M1 onward are supported, though alpha generators run slower on Mac. The app is free under CC BY-NC-SA 4.0; donations are optional.
