CrossFrame - Design Once for Every Format is an After Effects plugin from Ciaran Duffy for building an animation once and adapting it to multiple delivery formats. You work inside a single Global Stage, then switch between 16:9, 9:16, 1:1, 4:5 and custom layouts without rebuilding the piece for each one.
Workspace Overrides let you adjust individual formats independently without breaking the master layout, so a tweak made for one aspect ratio stays contained to that format. Built-in guides cover TikTok safe area, caption safe zones and custom margins, and you can take a snapshot of the current frame or output directly to the selected aspect ratio. The interface is designed to feel native to After Effects.
It suits motion designers delivering several formats, agencies running multi-platform campaigns, and anyone producing social content for TikTok, Instagram and YouTube who wants to avoid duplicating comps to resize animations. Version 1.3 added multi-format overrides for fine-tuning each aspect ratio independently.
