Who are we?
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). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

I'm a big fan of AV1, I've reencoded TiBs of video files to AV1. Reencoding is always going to lead to some quality loss, it just depends how much you notice it. For me I, don't see any quality loss going from h265 to AV1 in any videos I have done with my settings. But the biggest screen I use is 32inch 1080 monitor from about 5 years ago.
Its totally subjective so it may be worth taking a couple of your favourite video files and testing out a bunch of different settings and comparing the quality to see if theres a noticeable quality loss. Then you can weigh up the quality vs time taken vs storage cost to see if its worth it to you.
It can be slow, depending on what hardware you're working with but I've seen massive speed improvements over the past few months. ATM, I'm getting between 10 - 20 times speed up. So if I encode a 10 minute video, it takes between 30-60 seconds. This is with a 7700x, 12 cores. And I'm getting anywhere from ~10 times smaller file size to ~70% the original size.
Another option I use sometimes is converting to 720p from 1080. I do this on some videos that my parents take because their cameras aren't great and they have shaky hands so they're pretty blurry at the best of times anyway lol.
