slowmoVideo是一个创建慢速视频的开源项目。它可以将常速的视频，变成类似高速摄像头拍摄的视频。实现方式并非简单的低速播放(即复制帧)，而是通过运动估计，来做帧插值。

slowmoVideo is an OpenSource program that creates slow-motion videos from your footage.
But it does not simply make your videos play at 0.01× speed. You can smoothly slow down and speed up your footage, optionally with motion blur.
How does slow motion work? slowmoVideo tries to find out where pixels move in the video (this information is called Optical Flow), and then uses this information to calculate the additional frames between the ones recorded by your camera.
