How do I get ffmpeg.exe and where do I run this script?

What about googling a little bit? Look here: https://www.ffmpeg.org/download.html
You need to run this where you want to convert the mp4 to webm. As it is resource-expensive, choose a performant computer for that.
But this is just one of the methods. There are several converteres you can use.
