CorridorKey 2.0 is a neural AI-powered green and blue screen keying plugin for Windows and Mac that integrates with DaVinci Resolve, Nuke, After Effects, Premiere Pro, and Blender. It uses a trained model to predict and remove background screen color from semi-transparent foreground objects, preserving motion blur, bokeh, and fine hair detail. A time-awareness feature analyzes entire video clips to eliminate flicker and chattering mattes caused by compression or noise. Developed by Corridor Digital, the tool is sold as a one-time purchase with lifetime updates on the 2.x line and supports native 4K HDR with floating-point color depth.
