VFX compositing
Extracts straight foreground colors and clean linear alpha channels from green-screen footage.
When to use it
Use for AI green-screen removal, foreground extraction, alpha-matte generation, or CorridorKey setup and inference.
Give it green-screen frames and coarse alpha hints; it writes straight RGBA EXRs and linear alpha frames into the project.
