Key the hair, the blur, the glass
Key Studio Pro runs the CorridorKey neural keyer natively on Apple Silicon. For every pixel, it predicts the true color of the foreground and a clean linear alpha, as if the screen was never there.

The keyer inside Key Studio Pro is CorridorKey, built and trained by Niko Pueringer of Corridor Digital to solve the unmixing problem: recovering the true foreground color of every mixed pixel instead of guessing where the edge is. He open-sourced it at github.com/nikopueringer/CorridorKey, and if this app saves you an evening, that repository deserves your star.
Key Studio Pro runs those same weights natively on Apple Silicon and is released under the same Corridor Key Licence, which is why it is free and always will be. It is an independent app, not affiliated with or endorsed by Corridor Digital.
