you might be interested in pinchflat or tubearchivest which are made for this task

usage of public torrent tracker in germany is almost non-existent
the fear of getting sued by copyright laywers is pretty high

I believe thats only true for the unofficial version (Vaultwarden - API compatible to any Bitwarden app)

yea pinchflat has been easy to setup
also adding the videos to Jellyfin was easier than expected

transcode to a copy of that file
treat active torrented files as “do not edit”

I’m using pinchflat with Jellyfin (category mode “Music videos”) and it displays titles, descriptions and thumbnail correctly

pinchflat allows to embed metadata + thumbnail, idk if tube archivest has that too

to keep me sane I just use Freetube on destop and Tubular on phone

you can’t post comments on both but I feel this is a positive
