I don’t know why no one mentioned it yet, but those are very well known movies, albeit old, and will probably remain pretty easy to find in the near future.
If you still want to hold on to them you could download handbrake. This software lets you shrink a file size by a lot depending on the settings you’re working with, and how much you want to compromise the quality.
Also in terms of cost, local storage will always be cheaper than web, mostly due to the fact that cloud storage is paid periodically, while you can buy a decent sized SSD for 40 euros
I’m looking for this as well. Thanks to a reddit thread I got the 2016 version working but that’s pretty old and track change doesn’t work well
