Corridor Digital releases CorridorKey, an open-source AI tool for green screen keying trained on consensually gathered data

Niko Pueringer, a cofounder of video production studio Corridor Digital, created an AI model trained on CGI-generated green screen footage to automate green screen keying (the process of extracting a foreground image from a green background). He released the resulting tool, called CorridorKey, as open-source code and announced plans to release all original training data.

The community rapidly adopted CorridorKey and reduced hardware requirements from powerful workstations to ordinary consumer desktop computers, while making the tool significantly easier to use for non-expert video editors—all for free, compared to comparable tools that cost thousands or tens of thousands of dollars.

CorridorKey is licensed under a modified Creative Commons license, contains no surveillance or data-scraping features, and was trained entirely with data that were consensually gathered, with no billionaires involved in its creation.
