WebTools-NG VS plugins

You can use WebTools-NG's FindMedia tool to find what's missing between what Plex lists and what's on your filesystem.

In that case then I don't think there will be an easy way to transfer the metadata unfortunately (outside of some user-created script). One option that would at least help with the manual re-entry would be to use Tautulli's export feature or WebTools-NG's ExportTools to create a spreadsheet that has all the information in one place, and should be easier to copy/paste.

The good thing is, you'll still have all of your media sorted and organized on whatever hardware was hosting Plex, so you'll just need to install new software to host it. Make sure you're using something like Web Tools or Soundiiz to keep records of any playlists or collections and you'll be fine.

take a look at the Webtools-NG project you can extract different "info-levels" from your library as CSV and then import them into Excel or other Spreadsheet Applications and then create a table out of that and filter it based on what row you want and extracted. That way you could specifically search for that resolution and at least know which one it is.

Look at the Find Media tool in WebTools-NG ("latest" on right hand side to download).
