About CrossFrame – Design Once for Every Format
CrossFrame, developed by Ciaran Duffy, provides a Global Stage where an animation is built once and then reused across multiple delivery formats. Users can switch between 16:9, 9:16, 1:1, 4:5 and custom layouts, with Workspace Overrides that let per‑format adjustments without altering the master design. Built‑in guides cover TikTok safe area, caption zones and custom margins, and the plugin offers snapshot capture and direct output to the selected aspect ratio. Version 1.3 introduced multi‑format overrides for finer control. The interface is designed to feel native to After Effects and is compatible with After Effects 2020 through 2026.
