It's easy if you want to serve the video as it is but usually that's not what you want.
I have Plex (like a self hosted Netflix) on my home-server and some other people are also using it and on many different devices and connection speeds. It has to transcode the video on the fly and cache it depending on the client to have a good experience. You can't just serve 4k video to everyone.
