Despite skepticism I love to see experiments like that. If we all are able to run an open source model locally on mid-high end machines I'd be very happy.
I use my Immich instance locally as photos and videos storage for 7-8 months now. It's really amazing. Reading comments here I'd say it's medium-difficulty tier to set up. I have it on my Elitedesk 800 G3 mini, in Docker Compose, with hardware encoding and it's more than sufficient to handle this work. Never had a bug.
