Hi All

recently moved over from Plex to Jellyfin and really happy with the experience. I tried Cherryfloors cinema plugin but it didn't quite work for my requirements so i built my own.

Trailers4Jellyfin brings a real cinema experience to Jellyfin by automatically downloading trailers for upcoming and recently released movies and playing them before your movies start, no separate Cinema Mode plugin required.

It pulls trailers from TMDB/YouTube based on sources you choose (Now Playing, Upcoming, Popular, Top Rated) and saves them to a folder on your server. When you play a movie, the plugin queues a configurable number of trailers beforehand, optionally matching them to the genre of what you're about to watch e.g. horror trailers before horror films, family trailers before animated movies, and so on.

Trailers rotate automatically: watched trailers are removed and a configurable cap keeps your disk usage in check, so the pool stays fresh without any manual housekeeping.
