4451 movies
398 series / 36130 episodes
Taking up 25.48tb after conversion to HEVC compressing it ~40%
Every series is monitored for new episodes which download automatically; and there's a dozen or so public IMDB lists being monitored for new movies from studios/categories I like. Anything added to the lists gets downloaded automatically.
Then there's Ombi gathering media requests from my friends/family to be passed to sonarr/radarr and downloaded.
At this point, the library continuously grows on its own, and I have to do little more than just tell it what I want to watch.

I used to use the built in convert options in Emby server, but recently switched to Tdarr to manage all my conversions. It's got far more control/configurablity to encode your files exactly how you'd like.
It can also 'health check' files by transcoding them, but not saving the output; checking for errors during that process to ensure the file can actually be played through successfully. With 41k+ files to manage, that made it much easier to find and replace the dozen or so broken files I had, before I found them by trying to play them.
Fore warning; this is a long and intensive process. Converting my entire library to HEVC using an RTX 2080 took me over 2 months non-stop. (not including health checks)
