在本系列教程中，我们学习在After Effects中几种改变素材快慢速率的方法，同时学习运动模糊和帧融合的几个技巧。

有很多不同的技术来重新定时，所有不同的优点和缺点，可能使一项技术是在另一个更适合你。

我们首先了解时间之间的差异拉伸，时间重映射，并Timewarping。

我们也学习了一些像像素的运动模糊和帧混合有用的技巧。

我们这样做，结合了几乎所有我们学习了如何创建一个独特的重影效果的技术单一的教训玩完过程。

这当然是给你的，如果你想了解如何让您的画面看起来就像是拍摄高速摄像头，同样的剪辑中创建快速和慢速运动之间的共混物，或者干脆让你的镜头向后播放和停止。

无论是哪种情况，这当然有一切你需要的时间覆盖。

In this series of tutorials, we’ll learn various methods for changing the timing of our footage in After Effects.

There are lots of different techniques for retiming, all with different pros and cons that might make one technique be a better fit for you over another.

We’ll begin by understanding the differences between Time Stretching, Time Remapping, and Timewarping.

We also learn a couple of useful tricks like Pixel Motion Blur and Frame Blending.

We finish off the course by doing a single lesson that combines nearly all of the techniques that we learned to create a unique ghosting effect.

This course is for you if you want to learn how to make your footage look like it was shot with a high speed camera, create blends between fast and slow motion within the same clip, or simply make your footage play backwards and stop.

Whatever the case, this course has all your timing needs covered.
