Plex Naming Convention: Movies, TV Shows and Artwork

Wrong posters, misplaced episodes or TV shows detected as movies in Plex usually come down to naming. This guide covers Plex's official conventions for movies, episodes, local artwork and subtitles.

Where Plex's conventions come from

Plex scanners inherit the Kodi / XBMC convention: the folder hierarchy says what something is, the filename says which episode it is. Both live in the naming itself — Plex has no extra database mapping.

Movie naming

  • The standard form is title (year) with straight parentheses
  • Local artwork: poster.jpg for the cover, fanart.jpg for the backdrop
  • Subtitles as video-name.language.srt so Plex lists them as language tracks

├── Blade Runner 2049 (2017)/
│   ├── Blade Runner 2049 (2017).mkv
│   ├── Blade Runner 2049 (2017).zh.srt
│   └── poster.jpg
└── Whiplash (2014).mp4
                    

TV show naming

  • show (year)/Season xx/show.SxxExx is the most compatible combination
  • Extensions matter: .mkv, .mp4 and .ts are all recognized
  • Multi-episode files as S01E01-E02, specials as S00Exx

Naming that Plex gets wrong

Avoid

                      Game of Thrones Episode 1.mkv      ← no SxxExx, no episode number
GOT.1x01.mkv                       ← 1x01 is non-standard
Some.Movie.2019.1080p.BluRay.x264.mkv  ← release tags interfere with matching
                    

Normalizing a library for Plex with VRenamer

  • Add the media folder as an SMB / WebDAV file source
  • After scanning, VRenamer separates movies from shows and groups episodes by season
  • It scrapes TMDB and outputs name (year)/Season xx/SxxExx
  • Subtitles and local images are renamed to match their video, preserving Plex sidecar pairing
  • Run Scan Library Files in Plex when you are done

FAQ

Plex thinks a TV show is a movie.

Check the library type. Shows must live in a TV Shows library — no amount of correct naming fixes a library created as Movies.

Do local artwork filenames matter?

They do. poster.jpg is the cover, background.jpg / fanart.jpg the backdrop, and Season01-poster.jpg the season cover. Plex prefers local images when the names match.

Can Plex match Chinese titles?

Yes, provided a localized title exists on TMDB / TVDB. If it cannot match, keep the original title too or match manually once in Plex.
