EFX Keying-Alpha Plugin Suite

This suite of plugins consists of many tools developed over many years of compositing when off-the-shelf effects in After Effects would not provide satisfactory results. Some of them solve small problems, like softening an edge of a matte, others evolved into full blown keying solutions.

Feature highlights:

• combine alpha mattes of different layers with one simple effect,
• clean an alpha from small speckles left after keying noisy footage or difference matte,
• feather a matte edge "outwards" - you don't lose thin details,
• remove a dark edge after keying - this happens when the camera had sharpening turned on,
• tell the despiller which pixels he should despill and which to leave alone,
• difficult spill case? Just select the pixels with spill on them and use any of the normal AE effects to remove it,
• select pixels based on their color, luminosity or even transparency.
