I’m looking for a way to accurately compare two Plex Server Libraries. I’ve build a POC app that connects via API to both libraries.

I can loop through them and do some comparisons but it appears the only thing I can go off of is Title? Is there not a unique ID for the Plex Movie Scanner that would be consistent across Libraries?

the imdb tt # is embedded in the guid field - assuming you can pull that via the API and massage it a bit

guid=“com.plexapp.agents.imdb://tt4972582?lang=en”

You can get it via the API.  
I do that with ExportTools

That’s what I thought too, but I don’t have a value for Guid in any of my movies. (Using Plex Movie Scanner).

Anyone observed this? I even tried re-matching a movie and see if it pulled it in.

Only for home movies, so in short, Nope
