What It Does
EFX Keying-Alpha Free provides three targeted tools for refining keys and building alpha mattes in After Effects. These plugins handle common keying tasks: selecting pixels by opacity, removing color spill, and isolating areas by brightness.
Key Features
EFX Alpha Select lets you select pixels based on their opacity value. Useful when you need to isolate semi-transparent areas or refine an existing alpha channel.
EFX Despill removes color fringing from green or blue screen footage. You specify which pixels to despill and which to protect, giving you control over areas like skin tones or wardrobe that shouldn’t be affected.
EFX Luma Select selects pixels based on their luminosity. Helpful for creating mattes from brightness values or isolating highlights and shadows.
Who It’s For
Compositors and VFX artists working with keyed footage or building custom mattes. These tools cover basic keying needs without the complexity of the full 17-plugin suite.
Pricing
Completely free. The full EFX Keying-Alpha Plugin Suite ($49.99) includes these three plugins plus 14 additional tools like Alpha Choke, Edge Blur Keyer, and Despill Advanced. If you already own the suite, you don’t need this separate download.
