We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

Beware you don't really "compress" the videos like zip files but rather re-encode them, which is not lossless. Encoding is a very computation-heavy task that can only be brute forced with more raw hardware power.
You should make more research and experiments before doing this, no one can give you a "one size fit them all" solution when it comes to encoding.(i.e. you want to prefer speed or quality, there are tons of option) For starters if your GPU supports hardware decoder+encoder you can use it to speed up the encoding process, this is far faster than using only CPU to decode and encode.
Have a look at what HEVC is if you want to have good balance between size while preserving quality.
