PV Feather expands After Effects with per-vertex feathering control! Users have been requesting better feathering control within After Effects for quite some time. PV Feather (the "PV" stands for "per vertex") performs feathering by using an inner mask for filling, and an outer mask for feather control. The distance between the inside and outside mask controls the amount of feather. PV Feather uses AE's built-in mask splines, so there there is no new spline interface to learn!
