This regex is ultimately used by a Plex Media Server Agent to parse various information from a filename when Plex is scanning a media directory.
The regex uses named groups studio and clip_name to store the information that is parses so that it can be easily referred to pragmatically by Plex.
The following examples show how the regex parses the filename passed to it by Plex. Note that Plex passed the filename only and removes the file extension and directory.
Filename;
[Studio Name] - Movie Titleparses into: studio:Studio Nameclip_name:Movie Title
The regex accommodates for several variations in the filename:
Filename:
[Studio Name] Movie Title
Filename:(Studio Name) - Movie Title
Filename:(Studio Name) Movie TitleFilename:Studio Name - Movie TitleFilename:{Studio Name} - Movie TitleFilename:{Studio Name} Movie Title
will all parse the same and have the same result as the first example.
