CorridorKey 2.0: AI Green Screen Keying for After Effects and More

CorridorKey 2.0 brings Corridor Digital’s AI green screen keyer to After Effects, Premiere Pro, Resolve, Nuke and Blender. Features, beta pricing, hardware needs and the free GitHub version.

Top 10 Ways to Use the AI Assistant in After Effects

CorridorKey 2.0 is the new version of the AI green screen keyer from Corridor Digital, and it now comes as paid plugins for After Effects, Premiere Pro, DaVinci Resolve, Nuke and Blender, alongside a free version you can run yourself. School of Motion covered it in its November 2 Motion Mondays roundup. Here’s what CorridorKey 2.0 does, what it costs, what hardware it needs, and where it fits in a motion design workflow.

What is CorridorKey 2.0?

According to corridorkey.com, CorridorKey is “neural green and blue screen keying for Windows and Mac”, and the plugin is Corridor Digital’s first official plugin release. The site credits Alê Alvaro with plugin development and Zachary Harris with model design and training. The GitHub README says the 2.0 model was designed and trained by Zachary Harris in collaboration with Niko Pueringer and Corridor Digital.

Instead of building a key from colour ranges and spill controls, CorridorKey uses a trained model to separate the subject from the screen. The site highlights a few features:

  • Time awareness. It analyses the whole clip, which the site says eliminates flicker and chattering mattes.
  • Semi-transparent colour. The site says it predicts the colour of semi-transparent foreground objects, an area where classic keyers often struggle.
  • AlphaHint input. You can optionally give it a single black-and-white image or a video as a hint for what should be kept.
  • High-end formats. Native 4K and higher, HDR support and floating-point colour depth.

Which apps does CorridorKey 2.0 support?

The site lists plugins for DaVinci Resolve, Nuke, After Effects, Premiere Pro and Blender, and says one purchase gets you every plugin, with no subscription. A standalone app is included too. The site describes it as the best tool for bulk shots and says more than 400 VFX shots for Corridor’s Son of a Dungeon went through it.

On Mac, the site says you get the standalone app, the OpenFX plugin and the Blender add-on, and since build 2.0.0.146 the After Effects and Premiere Pro plug-in.

Pricing and licences

The site shows CorridorKey 2.0 in a beta launch with reduced prices:

  • Personal: $49.50 one time during the beta, returning to $99 on November 21. One person, up to two machines, lifetime updates on the 2.x line and a 14-day money-back guarantee.
  • Studio: $42.50 per seat during the beta (regular $85), for 5 to 300 seats with one machine per seat. The site says the studio offer ends November 21, 2026.

The banner on the site says beta launch pricing ends November 20, and full release with regular pricing begins November 21.

The free version on GitHub

There’s also a free, more technical version on GitHub. It runs from the command line with Python and needs CUDA-enabled PyTorch, ffmpeg and model weights of about 5 GB downloaded from Hugging Face. A basic run looks like this:

python infer.py --input /path/to/input.mp4 --output_dir /path/to/output

It can output an alpha matte, the foreground, a checkerboard preview and a cutout. The README says you can use it freely for commercial or personal work, including processing footage for client projects. You may not sell the tool or offer it as a paid service without Corridor Digital’s permission, and organisations with more than US $20 million in annual revenue need a plugin seat for each person using it. The README describes the licence as a variation of CC BY-NC-SA 4.0 with extra terms, so read the full licence before using it in a studio.

Hardware requirements

CorridorKey is GPU-heavy. The site lists:

  • Windows: an NVIDIA RTX 30 series or newer GPU is recommended. RTX 20 series is in beta. Windows 11 or Windows 10 22H2.
  • GPU memory: 4 GB for shots up to 1440p, 6 GB for 4K.
  • Mac: M-series Macs with macOS 14 or newer. Intel Macs aren’t supported.
  • Not yet supported: AMD GPUs and Linux are listed as planned.

The free GitHub version currently needs an NVIDIA RTX 30 series or newer GPU with the same memory limits.

What CorridorKey 2.0 means for motion designers

Most motion designers don’t key every day, but green screen shows up constantly in real projects: a presenter in an explainer, a product shot for an ad, a talking head for a social clip. A key that holds up without an hour of cleanup changes how quickly those jobs move.

The bigger news is that the plugin lives inside After Effects and Premiere Pro. Once the subject is cleanly separated, the rest is ordinary motion design work: titles, callouts and camera moves around the keyed footage.

That’s where our tools fit in. Our Phone Camera Controller for After Effects lets you record a handheld 3D camera move with your phone, which helps keyed footage sit in a scene that feels filmed rather than static. For the graphics around it, our free 2000+ Animation Presets pack covers text and element animation in both After Effects and Premiere Pro, and our AI Assistant for After Effects can build keyframed titles and lower thirds from a written prompt.

Should you try it?

If you key footage regularly and have a supported GPU, the beta price makes the plugin easy to test, and the 14-day refund lowers the risk. If you’re comfortable with Python and only need occasional keys, the free GitHub version is worth a look. If you’re on an AMD GPU or Linux, you’ll need to wait, since both are listed as planned.
