About CornerPinner

CornerPinner is a script for Adobe After Effects that focuses on corner‑pin workflows. It can add simple corner pins, convert any supported corner‑pin effect to another type, generate basic mattes from pins, round pin edges, rotate corner values, and invert pins for tasks such as stabilising a Mocha pin in a pre‑composition. Supported effects include Corner Pin, RG Corner Pin, CC Power Pin, BCC Corner Pin, GenArts S_WarpCornerPin, Bezier Warp, Card Dance, Card Wipe, RE:Map Planar, 4‑Color Gradient and FxFactory Pro Free Distort. Version 1.2 (released October 27 2025) added invert and pre‑comp options and extended compatibility through After Effects 2026, while still working on releases back to CS6. The script is distributed for free via aescripts and includes a demo video.
