【教程介绍】AE 和 PS 一样有笔刷工具和仿制图章工具，作用跟PS中的效果相仿，不过AE中能制作动画效果，教程详细的介绍了笔刷里的用途，如果制作类似水墨动画效果，后续还介绍了仿制图章工具的使用，最后还通过工具制作了如上图的水墨效果动画。

In this series of tutorials, we’ll talk about the brush tools in After Effects.

We’ll start by getting familiar with how the brush tool operates and the various controls and settings that are available.

We’ll talk about techniques for animating the paint strokes and also ways to use the brush tool to create animations for revealing layers in a composition.

We’ll go over how we can add expressions to paint strokes that we’ve created to animate their properties.

We’ll also talk about the eraser tool and its similarities and differences to the brush tool.

Next we’ll explore how the clone stamp tool works and we’ll learn some great ways to preview clone sources.

And finally, we’ll learn how we can combine tracking information with the clone tool to clone out imagery from moving footage.
