Writing a video file

In this section, we are going to see how we can write to video files using cv2.VideoWriter. However some concepts (for example, fps, codecs, and video file formats) should be introduced first.

Calculating frames per second

In the Reading camera frame and video files section, we saw how we can get some properties from the cv2.VideoCapture object. fps is an important metric in computer vision projects. This metric indicates how many frames are processed per second. It is safe to say that a higher number of fps is better. However, the number of frames your algorithm should process every second will depend on the specific problem you have to solve. For example, if your algorithm should track and detect people...
