Opencv-python reads video, processes it frame by frame, and saves it

1. Read the video

2. Save the video

I’m going to use this class

CV2. VideoWriter (videooutpath fourcc, 20.0, (1280960), True)

Videooutpath Output file name

Fourcc = cv2. VideoWriter_fourcc(* ‘XVID’) is the specified encoder

20.0 is the frame rate

(1280,960) is the video size

True refers to color

General encoder: “DIVX”,” MJPG”, “XVID”, “X264”

Note: use *’ mp4V ‘if you want to open it on a MacBook

3. Frame by frame

With the first two foundations, it’s easy

The above is all the content of this article, using the method introduced in the article can achieve the routine video frame by frame save, cut off and other operations, interested in learning more programming skills can watch the teaching video to continue learning ~
