如果你想开发AE脚本，就选择学习它。

在Adobe的主要脚本工具After Effects的CS3版本及以上。

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.
