Plex Media Server renames movies after customization

Plex Media Server Metadata & Adding Files
6

I see two issues:

  1. the file is a mp4 file. These often do contain nonsensical embedded “Title” meta tags.
    Perform these configuration changes in Plex to make Plex prefer metadata from online sources over embedded ones:
    Go to
  • Settings - Server - Agents - Shows - TheTVDB

In there, grab the line ‘Local Media Assets’ with your mouse and drag it downwards, so it ends up being at the bottom of the stack of active agents.
Repeat the same under

  • Settings - Server - Agents - Shows - TheMovieDatabase
  • Settings - Server - Agents - Movies - Plex Movie
  • Settings - Server - Agents - Movies - TheMovieDatabase

Afterwards, “Refresh Metadata” of the movie.

An alternative would be to remove all embedded meta tags from your file. You can use e.g. mp3tag to do that.
Another upshot of mp3tag: you can use it to also “optimize for streaming” your mp4 file. Since Plex is a “streaming server” this is highly recommended.

  1. I recommend you to create one subfolder per movie, particularly when you are using external subtitles.
    Otherwise, in time, library updates will take longer and longer, the more movies you add.
    So instead of
S:\Películas\
   The.Hobbit.An.Unexpected.Journey.2012.1080p.BRrip.x264.GAZ.YIFY.mp4

you’d use

S:\Películas\
   The Hobbit An Unexpected Journey (2012)\
      The.Hobbit.An.Unexpected.Journey.2012.1080p.BRrip.x264.GAZ.YIFY.mp4
      The.Hobbit.An.Unexpected.Journey.2012.1080p.BRrip.x264.GAZ.YIFY.srt

Tip: if those subtitles are in e.g. Spanish, rename the file to
The.Hobbit.An.Unexpected.Journey.2012.1080p.BRrip.x264.GAZ.YIFY.spa.srt
