How it works...

Writing video is performed using the cv2.VideoWriter class. The constructor takes the output video path, four characted code (FOURCC) specifying video code, desired frame rate and frame size. Examples of codec codes include P, I, M, and 1 for MPEG-1; M, J, P, and G for motion-JPEG; X, V, I, and D for XVID MPEG-4; and H, 2, 6, and 4 for H.264.
