什么是抽帧

抽帧是指在一段视频中，通过间隔一定帧抽取若干帧的方式，模拟每隔一段时间拍摄一张照片并接合起来形成视频的过程（即低速摄像）。

Frame extraction means that in a video, by extracting several frames at a certain interval, it simulates the process of taking a photo at regular intervals and combining it to form a video (low-speed photography).

每个视频在抽帧之前，都会先形成帧数。视频的帧数就是在1秒钟时间里传输的图片的量，也可以理解为图形处理器每秒钟能够刷新几次，通常用fps表示。

Before each video frame is drawn, the frame number will be formed first. The number of frames of a video is the amount of pictures transmitted in 1 second. It can also be understood that the graphics processor can refresh several times per second, usually expressed in fps.

每一帧都是静止的图象，快速连续地显示帧便形成了运动的假象。高的帧率可以得到更流畅、更逼真的动画。每秒钟帧数愈多，所显示的动作就会愈流畅，但文件会变得越大。王家卫的《重庆森林》就是很经典的运用抽帧技巧的影片。

Each frame is a still image, and displaying frames in rapid succession creates the illusion of motion. Higher frame rates result in smoother, more realistic animations. The more frames per second, the smoother the motion displayed, but the larger the file size. Wong Kar-wai's "Chongqing Forest" is a classic film that uses frame drawing techniques.

制作抽帧视频

打开桌面Pr，新建项目，从本地将需剪辑的视频与音频素材拖入画面时间轴上，开始编辑。根据自己的编辑需求将需要删除的片段位置按m键标记，（标记位置错误可以同时按住shift m来向右移动标记点或者同时按住ctrl shift m向左移动标记点），按照这种方式我们就可以对素材进行一个精确的定位。

Open the desktop Pr, create a new project, drag the video and audio material to be edited locally onto the screen timeline, and start editing. According to your own editing needs, press the m key to mark the position of the clip that needs to be deleted. (If the marked position is wrong, you can press shift m to move the marker to the right or ctrl shift m to move the marker to the left.), follow In this way, we can make a precise positioning of the material.

接下来选择剃刀，在标记点处；利用剃刀分割，针对性的将素材的一定长度的帧进行波纹删除，将后面的片段拖拽至衔接位置，补全空白。如果删除一定长度的帧之后，画面变化不大，我们就应该将中间需删除的帧的长度延长。最后，重复上述操作即可，整个过程操作比较简单但是非常的耗费剪辑者的时间和精力，但效果非常惊艳，值得大家上手操作。

Next, select Razor, at the marked point; use Razor to divide, delete a certain length of frame of the material, and drag the following clip to the connection position to fill in the blank. If after deleting a certain length of frame, the picture does not change much, we should extend the length of the frame to be deleted in the middle. Finally, just repeat the above operation. The whole process is relatively simple, but it consumes a lot of time and energy of the editor, but the effect is amazing and it is worth getting started.
