CorridorKey is a plugin implementation that makes Corridor Digital's CorridorKey easy to use across After Effects, DaVinci Resolve, and Premiere Pro. It also supports Nuke and NukeX, and it currently ranks among the most popular entries on aescripts.
The plugin includes a Tiling Mode that processes 256x256 tiles for higher effective resolution and lower memory usage, plus Auto Crop, which crops around the mask bounding box to avoid wasted compute on large transparent areas and is on by default. An optional QuickMatte input parameter lets you provide a custom alpha hint.
Version 1.3.0 arrived on April 17, 2026, bringing a 30% speed improvement along with bug fixes. Earlier updates delivered further performance gains and stability fixes across macOS and the installer. A demo video is available.
