I can confirm and I do use this feature of jellyfin. It works great. The reader is unusable. I use Librera for reading. It's great, free, and open source.
So my flow is biblio, mam, library Genesis, Anna's. Then to jellyfin folder that it reads automatically. Then I can download that to any device connected to the jellyfin server. Local is easy, abroad through tailscale.
All of these recommendations are great. I'm always pleased to see so many cinemaphiles. I like lists, and have found many of my favorites from them.
Ebert's Great Movies List is perfect.
The Criterion Closet Picks, see the greats talk about the greats.
The Janus Collection has a lifetime of stuff.
