After Effects 5.5

第一章 After effects概述

概述：After effects是用于影视后期数字合成的软件，它可以对多层的合成图像进行编辑，制作出天衣无缝的数字合成效果；关键帧；路径概念的运用使after effects可以方便的编辑二维动画；它有着令人眼花缭乱的特级系统，使after effects能够实现使用者的一切创意。 一．After effects的工作界面介绍 After effects的工作界面如图1-1所示

图1-1

（一）项目窗口

在工作界面的左侧是项目窗口，每次启动after effects时，都自动建立一个名称为“untitled project.aep”de 新项目，after effects就是以项目为单位进行影片制作和管理的，可以把影片需要的素材输入到项目窗口中，这些素材包括音频文件、视频文件，静态图片等类型。如图1-2所示

（二）时间线窗口

当建立合成的时候，同时产生了该合成的时间线窗口，在after effects中，时间线窗口以时间为基准对层进行操作，在时间线窗口中可以调整素材层在合成中的时间位置
