OpenCV: Creating a video with OpenCV
https://docs.opencv.org/4.x/d7/d9e/tutorial_video_write.html
Due to this OpenCV for video containers supports only the avi extension, its first version. A direct limitation of this is that you cannot save a video file larger than 2 GB. Furthermore you can only create and expand a single video track inside the container. No audio or other track editing support here.
