【脚本介绍】

Mouth Shapes是一个免费且简单的AE脚本，只需要点击一个按钮，即可让嘴唇同步变得容易。 在创建角色动画时，这是一个非常有效的工具，但它也为您的后期效果工作流程提供了一个强大的资源，无论何时您需要切换多个层等等。

Mouth Shapes is a FREE and simple script born from a deep seated hatred of lip syncing and the setup that goes into it. We take that boring long process and boil it down to a single button press; lip syncing made easy. We’ve made a very effective tool in creating character animation, but it also makes for a powerful asset in your After Effects workflow anytime you need to toggle multiple layers, and much more.
