SOLVED: Jellyfin not adding new movies to library

[tayfun369]

Hi,
I am running Jellyfin 10.10.7 via docker-compose on a Debian VM for some weeks now.

My media folder is mounted via SMB. Every movie is in its own subfolder with the stadnard radarr naming convention. Until now everything worked flawlessly. Yesterday I downloaded a movie which got picked up by Jellyfin, today 3 movies of which only one got picked up and the other ones won't show up in the library.

What is weird though is that Jellyfin added backdrop/folder.jpg etc. to the folders of the movies. But they are not showing up on the library still.

Here is the logs from today:

Movies that are not added are "ma ma (2015)" and "Memory (2023)", the added one from today was "Sibyl (2019)" and "Conclave (2024)" from yesterday.

I also had an error that a collections (Sammlungen) folder couldn't be found in the configs which failed the library scan, so I manually added that one which fixed that error.

Jellyfin finds the movies and creates trickplay.

Did you changed anything else on library settings like metadata providers?

From home screen, on left menu there's manage metadata, can you find the movies there?

Code:

No changes to the library or metadata providers. I realized it added trickplay and other image files that's why I found it weird.

The tip with the metadata manager was fire. I found them added as wrong movies. Memory is the wrong Memory from 2022 instead of 2023 and ma ma got added as Mad Max. Do you know how can I fix that without manually changing every entry?

Edit: Found out. "Identify" in the 3-dot menu of the movie. Fixed it. Thank you for the idea to check the metadata manager.

You can help jellyfin find the correct metadata adding tmdbid or imdbid to movie folder

Code:

"Film (2018) [tmdbid-65567]

https://jellyfin.org/docs/general/server/media/movies

If you're using a movie manager like Radarr you can set movie folder (enable show advanced)

Code:

{Movie Title} ({Release Year}) [tmdb-{TmdbId}]
