Can you add [Language Code] to Movie filenames to avoid manual matching

Plex Media Server Metadata & Adding Files

Server Version#:1.20.3.3483-211702a9f
Player Version#:

I have three libraries for MP4 Movies based on resolution.
Movies-4x3 (PAL movies)
Movies
Movies-HD

All have English as a standard language but contain Movies in other languages.
I know I can create more libraries with different languages, and
I use that for TV-Series but I would like to avoid that for my Movies.

I have a backup NAS and I sync them manually using a hard disk.
I would like to avoid having to manually match the non-English Movies twice.

Is there a way where I can either name the movie file or embed data in the movie
file so that Plex tries matching with the correct language?
Similar to the method used for sub-titles.

Have you looked at the audio track language of the movie files? If the language is labeled on the track, Plex recognizes it.

If you’re on a MAC, I used Subler to fix those files with mislabeled audio track language.

No. Plex will only auto-match using the library you’ve set for the library.

You will need to use multiple libraries if you want Plex to do this automatically.
