What It Does
CorridorKey for Green Screens brings Corridor Digital’s open-source CorridorKey keying technology into a ready-to-install plugin for professional compositing applications. Rather than setting up the project manually from the GitHub source, this implementation by Baskl.ai wraps it into a conventional plugin that works directly inside After Effects, Premiere Pro, DaVinci Resolve, and Nuke.
The underlying algorithm is AI-assisted, designed specifically for green screen separation. It’s available for free.
Key Features
Tiling Mode. Processes footage in 256x256 tiles, which allows higher effective resolution output while keeping memory usage low. Useful when working with high-resolution green screen footage.
Auto Crop. Automatically crops processing to the mask bounding box, avoiding wasted compute on large areas of transparency. Enabled by default.
QuickMatte Input. Accepts an optional custom alpha hint to guide the keying process, giving you more control over tricky areas like hair or fine edges.
Cross-application compatibility. Works in After Effects (2020 through 2026), Premiere Pro (2020 through 2026), DaVinci Resolve (18 through 21), and Nuke/NukeX (12.0 through 16.0).
Who It’s For
Anyone doing green screen work who wants a free, AI-based keying option without manual setup. Particularly useful for editors and compositors who work across multiple applications, since one install covers the major NLEs and compositing tools. The open-source foundation means the algorithm is auditable via the CorridorKey GitHub repo.
