Description

Professional Edge Extension in After Effects

Rotoscoped and keyed footage can have discolored pixels at the edges, especially in motion-blurred areas. Extendo erodes away those bad edges and replaces them with colors that match your inner core footage.

Edge extension is a technique used in Nuke, Flame, and Fusion—and is now finally available in After Effects.
