About CorridorKey by blace.ai

CorridorKey is a green‑screen keying plugin for After Effects and Premiere Pro, developed in cooperation with Corridor Digital and powered by blace.ai. The plugin includes several custom‑trained AI models that repair transparent pixels, delivering compositing‑ready results. Built entirely in C++ for stability, it reports rendering speeds two to four times faster than comparable tools. Users can combine it with After Effects’ Advanced Spill Suppressor to eliminate color bleed. Optimal performance is observed on NVIDIA GPUs with Mercury CUDA acceleration on Windows, while AMD GPUs also receive hardware‑acceleration support. The plugin supports After Effects and Premiere Pro versions 2024, 2025, and 2026.
