Adobe After Effects Motion Graphics AI Skill Guide (Claude)

Overview & Engine Architecture

After Effects is layer-based: Project → CompItem → Layers → Properties / Keyframes / Expressions. Automation is primarily ExtendScript (JSX, ES3 dialect) against app.project, CompItem, AVLayer, and renderQueue. Delivery: Render Queue (blocking render()), Queue in AME (queueInAME), or Essential Graphics → .mogrt. Dynamic Link ties comps into Premiere.

Keep scripts ES3-compatible (var, no arrow functions/template literals in JSX shipped to AE).
