It’s been a long time since I needed to create an application to write videos to file with OpenCV, so when I sat down to compose the code for this blog post, I was very surprised (and super frustrated) with how long it took me to put together the example.

You see, while the functions used to create video files with OpenCV such as cv2.VideoWriter, cv2.VideoWriter_fourcc, and cv2.cv.FOURCC are quite well documented, what isn’t nearly as documented is the combination of codec + file extension required to successfully write the video file. Make sure you’re in a secluded place away from children - there will be a lot of swearing and cursing.Play around with various codec + file extensions until the video writes to disk successfully.Do research on the video codecs installed on your system.However, if you are trying to write videos to file with OpenCV in your own applications, be prepared to: My intention with this tutorial is to help you get started writing videos to file with OpenCV 3, provide (and explain) some boilerplate code, and detail how I got video writing to work on my own system. Let me just start this blog post by saying that writing to video with OpenCV can be a huge pain in the ass.
