The most reliable source is here https://www.videohelp.com/software/MediaInfo There are numerous other sites that make you jump through unnecessary hoops etc.
Or the Media Info website https://mediaarea.net/en/MediaInfo This also has all the available distros on it.
That was my traditional place to go but last week when I tried, it may have been taken over? Lots of confusing ads etc. Anyway seems ok today. Over the years I’ve found if you want a simple Windows or MAC version Videohelp.com has been straight forward. The worst you can do is a Google search for the site.
