Python OpenCV
About Lesson

In this Python OpenCV lesson we are going to learn about Python OpenCV Writing to Video, basically we want to add a circle in our video.



This is the complete source code for this lesson.





This section of code is for creating and reading from input file. If the input is a camera pass 0  instead of the video filename.




When we want to write a video in OpenCV we need some more works. We need to create a VideoWriter object. first, we should specify the output file name with its format (eg: output.avi). then, we should specify the FourCC code and the number of frames per second (FPS). Lastly, the frame size should be passed.




We want to add a circle in the video, so this code is used for creating a circle.




Run the code and this is the result.
