vangel76andClaude Opus 5.5 39bd0efac2 Luma Key: Key Out Brighter and Darker cut hard at Threshold, as After Effects ...

After Effects' Luma Key removes everything darker (or brighter) than Threshold
and ignores Tolerance for those two key types; Tolerance only sets the band of
Key Out Similar / Dissimilar. EffectCraft ramped the matte over Tolerance, so
case 719 (a 50 % grey, Key Out Darker, Threshold 140, Tolerance 20) kept about
80 % of the layer where AE keys it out completely.

Measured in AE 2026 on a vertical grey ramp (cases 812-814): Darker keys up to
level 139.9 and keeps 140.1 (EffectCraft now the same row); Similar keys levels
120.3-160.0; with Edge Thin 1 / Edge Feather 2.5 the matte rises over rows
591-596 (EffectCraft within 0.2 of AE's alpha there). CPU and GPU.
