After Effects根据音乐波形匹配制作动画

本套CG教程，已翻译成中文，请享用。

如果提高动画的观赏性，秘诀之一就是将动画节奏与音频（无论是音乐还是语音）紧密匹配，所以有些动画电影在制作前就已经定下了音效节奏，我们可以根据声音来匹配制作动画，可以使用关键帧技术，也可以使用表达式来匹配音效，创建更引人注目的电影体验。本套After Effects课程教你如何“读取”音频波形以发现最有趣的点，以进行动画处理，然后巧妙剪切视频和动画运动关键帧以匹配音轨。包括定时过渡，断断续续剪切，使帧速率与速度匹配，些技巧将在Adobe After Effects中进行讲解，但这些技术本身适用于任何编辑软件。

Editing and Animating to Sound with Adobe After Effects. In this course, Chris Meyer teaches you how to “read” an audio waveform to spot the most interesting points to animate to, and then presents a variety of ideas for cutting video and animating movements to match your soundtrack. This includes timing transitions, making staccato cuts, matching the frame rate to the tempo, wiggling in time, expressing animations to sound, motion sketching to music, and more. Although these tricks will be demonstrated inside Adobe After Effects, the techniques themselves are applicable to virtually any editing or animation package. Reading an audio waveform. Spotting “hit points” in dialog and music. Placing markers. Creating a click track. Cutting, crossfading, and time-warping video to music. Timing visual events to music. Timing animation to music. Converting audio to keyframes. Motion sketching to music.
