AE脚本编程入门教程 FXPHD – AFX210: Introduction to After Effects ScriptingAE CS3及以上版本的脚本教程，很少见的教程，涉及到编程，注意，这个不是教你写表达式。

This course, taught by Lloyd Alvarez, will provide an introduction to the main scripting tools available in Adobe After Effects versions CS3 and above.

Scripting automates tedious tasks that can be done by hand in After Effects so a good working knowledge of After Effects is strongly recommended before taking this course.

After Effects can be scripted in ExtendScript (Adobe’s extended implementation of JavaScript.

) on both mac and windows as well as Applescript on the mac and Visual Basic on Windows.

This course will only cover ExtendScript because of its cross-platform nature and larger resource base due to its JavaScript foundation.
