I have been trying to clean up my Plex Titles, at the moment the Sort Title drops words like “A” and “The” from the title so it puts the video in the wrong order, in my opinion.
Also some Plex Display Titles have extra characters in like “A.Merry.Christmas” and I have been looking at cleaning that up to be displayed as “A Merry Christmas”
I have looking to do this using scripts to access the SQLLite database with the scripts in the link below
You can configure if/which prefixes of a title should be removed. This is usually done to avoid having 60% of your movies grouped under A and T because they use an article.
The „extra characters“ are probably based on embedded metadata in those files. You can configure Plex to ignore those in the library preferences (especially if you’re using some dubious sources that add garbage to those embedded information).
I used the library options on the Plex Server settings and I altered the Preferences.xml to stop it from storing the Titles without the leading characters
