Keyloom 3.0 pulls clean green- and blue-screen keys from video with CorridorKey on your own NVIDIA GPUs, across several PCs
Keyloom is a desktop app for Windows and Linux by Nick Pittas that keys green- and blue-screen footage with Corridor Digital's CorridorKey engine on an NVIDIA GPU. Version 3.0.0, released on 6 November 2026, adds new Board, Shot, Machines and Models pages, a drawing tool column for hints and a queue that shows each machine's progress when you render over a network.
What it does
You import clips or PNG/EXR sequences, build a rough matte (the hint) with SAM points, boxes and paint, GVM, BiRefNet or a chroma key, optionally refine it with MatAnyone2 or VideoMaMa, then key with temporal awareness, VRAM and despill controls. You review input, hint, foreground, matte and comp with an A/B wipe and deliver EXR/PNG sequences or MP4, MOV and WebM, in batches spread over every PC on your network.
Worth knowing
The repository has no top-level licence file; the CorridorKey 2.0 engine and weights are under the Corridor Key Licence v2 (CC BY-NC-SA 4.0 plus terms that forbid resale and paid inference services), while the images and video you make are yours to use commercially. Model weights are not bundled: the model manager downloads them, each under its creator's own licence. Only online installers are offered, and Keyloom must be running on every PC that renders.
