I am not a very heavy user of Jellyfin, there are weeks when I not add any new movie or series to my server.
However recently, and I mean the past 2-3 months for that, it feels like Jellyfin is getting worse at correctly recognizing media, especially movies as such.
Not sure I can give much examples here, as I also didn’t write down which movies caused issues. But I make sure the files are named as outlined in the documentation, with “title (year).extension”, I have not added any media IDs to filenames yet because well, it used to work really nicely.
The mismatched movies don’t really follow any pattern, they usually do not even include parts of the original title or year defined in the filename.
One thing I changed recently, but I am sure the issues started well before that, is that I have movies in an additional subfolder to sort for the starting letter, in order to unclutter my folders. E.g. before it went into /movies, now it would go into /movies/a if the name starts with a. I could try next time moving the file to the main folder and test if that works better, but I doubt it.
Any suggestions or is it just getting worse? When I use the identify option I can always find the correct movie, and with the frequency I add movies it is really just a small annoyance, but still…


In your movie media library make sure that “the movie db” is the top Metadata service. I once had another service at the top after an update and it made things strange.
I’ll have a look at that, thanks!
