CorridorKey is a keying plugin for After Effects built around one hard job, pulling a clean matte from green screen footage. Anyone who has keyed wispy hair, smoky edges or fast motion blur knows the fringe and spill that basic keyers leave behind. CorridorKey was made with the Corridor Digital team and focuses on believable edges and true foreground color, so composites settle into the new background with far less cleanup work. Updated Aug 17, 2026.

Key Features

• Green screen keying built for difficult real world shots
• Fine edge handling for hair, blur and soft detail
• Foreground color recovery for more natural composites
• Spill control that keeps green edges out of the subject
• Runs as a plugin inside After Effects on Mac

How to Download

1. Open the vendor product page for CorridorKey and get the Mac plugin package.
2. Run the installer and follow the steps for your After Effects version.
3. Restart After Effects, apply the effect to a green screen layer and refine the matte.

System Requirements

You need a Mac with a supported version of Adobe After Effects installed. Keying at high resolutions is demanding work, so a machine with a strong graphics card and plenty of memory will feel much smoother.
