XBMCnfoMoviesImporter.bundle VS XBMCnfoTVImporter.bundle

Unfortunately, Plex does not support NFO files, at least not with the new Metadata Agents. You would need to use 3rd Party Metadata Agents for Movies and TV-Shows and then use a separate library to use them since 3rd Party Agents don't work anymore in tandem with the new Plex official Agents.

You can use the XBMCnfoMoviesImporter which reads the NFO file that you can create with some other application.

While Plex normally doesn't read nfo files, you can install XBMCnfoMoviesImporter and XBMCnfoTVImporter agents to make it possible.

I use tinyMediaManager to add .nfo files, artwork etc. to all my movies and tv shows. To prevent Plex from using its automatic metadata retrieval (which in my experience sucks for more obscure stuff) and use my manually curated local metadata instead I had to install 3rd party plugins from github and while they work for now there's no guarantee that they will continue to do so.

To utilize NFO files you would need the NFO importer Metadata Agent for Movies and TV-Shows.

I use Adult Media Manager in conjunction with XBMCnfoMoviesImporter

For example, you could create NFO files to store the metadata next to the video files and then use the NFO Movies Importer or NFO TV-Show Importer to read those NFO files that you can create with tinyMediaManager. You could also look into Plex-Meta-Manager but either of those solutions would require that you already have those files or create them, nothing really to get them out of plex in an easy way.

The first one would be to use a different metadata Agent there NFO importer for TV-Shows and Movies. They will read the NFO files and add them to your Library item. AFAIK you can create those NFO files with TinyMediaManager This would give you total control over the metadata being added.

Tried Phoenix but I prefer to have a bit more granular control over this stuff so I use AdultMediaManager to scrape metadata and generate NFO files then use XBMCnfoMoviesImpprter as a library agent to get that displayed in Plex properly.

Download this agent. Follow instructions under "Manual Installation." Now you have a new importing agent for plex.

Fourth: Using a different Agent. There is an NFO Importer that can read NFO files that you would need to create. This would make the metadata completely local and "refreshing" it would mean that you have to change it manually. Unfortunately, those "type" of agents are 3rd Party and rely on an old dependency in plex. While they still work, there is no official statement yet when those metadata agents will stop working. Plex has deprecated plugins for 4-5 years now which Metadata agents are technically a part of. That also means that you wouldn't be able to mix those agents together. Unfortunately, you cannot select a 3rd Party agent to retrieve metadata for a library that is mainly using the new and official plex metadata agents.

For example, you could create NFO files to store the metadata next to the video files and then use the NFO Movies Importer or NFO TV-Show Importer to read those NFO files that you can create with tinyMediaManager.
