PlateAlphaCorridorKey is a neural keying model for green screen, with PyTorch and MLX backends. The model is community work; my contribution is the OFX plugin for Natron and the wrapper that fits it into the compositing pipeline.
The result is AI-assisted rotoscoping inside an open-source compositor, running locally. In the comparison above: the green-screen plate on the left, the extracted alpha channel on the right.
