It is shown here with some random generated 2d images, which ware plotted via matplotlib. By using the figure handle the animation is created. So you can plot your matplot figures in your own way and used some similar syntax to create an animation. First of all you must install the matplotlib package, e.g. from https://pypi.org/project/matplotlib/ Then you must install the ffmpeg codec. A detailed description can be found on: http://blog.gregzaal.com/how-to-install-ffmpeg-on-windows/ The build version of the ffmpeg codec can be downloaded here: http://ffmpeg.zeranoe.com/builds/ Download and unzip the builds files to your harddrive. Typically the folder is like: C:\Program files\ffmpeg The bin folder of ffmpeg must be added to the path variables of your system: C:\Program files\ffmpeg\bin Finally start the command prompt and run the command: C:\Program files\ffmpeg\bin\ffmpeg.exe -codecs or easier: ffmpeg -codecs ..
