Lynda.com 出品的時長1小時35分鐘的 After Effects系列學習第9部：表達式的運用 視頻教程。After Effects眾多功能中最強大，但未被充分利用的是表達式，此功能可以把代碼應用在動畫層屬性上，比較關鍵幀在時間軸中的每個值。表達式的優點是可以使多參數和層能夠遵循主層引導或控制效果的能力，使其更容易的支配復雜動畫，迅速適應客戶的變更。教學由Chris Meye演示了如何使用After Effects創建簡單而有十分有用的表達式能夠運用到各種項目上的大部分工作。本教程附帶練習文件。

Course name: After Effects Apprentice 09: Expressions

Authors: Chris Meyer Trish Meyer

Duration: 01h 35m

Released on: 7/27/2011

One of the most powerful but underused features in After Effects is expressions, which can be used to animate layer properties with code, as compared to explicitly keyframing every value in the Timeline. One of the strengths of expressions is the ability to have multiple parameters and layers follow the lead of a master layer or controller effect, making it much easier to coordinate complex animations and quickly accommodate client changes. In this introduction, Chris Meyer shows how to let After Effects do most of the work by creating simple but very useful expressions that can be put to work on a wide variety of jobs. Exercise files are included with the course.

The After Effects Apprentice video lessons on lynda.com were created by Trish and Chris Meyer and are designed to be used on their own or as a companion to their acclaimed book, After Effects Apprentice. We are honored to host these tutorials in the lynda.com Online Training Library®.

Topics include:
