YouTube-Agent.bundle VS WebTools-NG

This is the way to go. I don't know the exact specifics, but there are some good Plex Agents for Youtube, including https://github.com/ZeroQI/YouTube-Agent.bundle and https://github.com/benkle-libs/YTDL-Agent.bundle

Ah, some assumptions go out the window when you start using third-party agents/scanners, since they don't need to (and usually don't) follow Plex's normal naming conventions. That said, I'm not sure what's going wrong on your end, since I just followed the setup instructions here, copied your file names above, and that seemed to work (minus the name of the show getting set to the file path for some reason): https://i.imgur.com/hivSzYl.png

It's the Youtube video IDs. The YouTubeSeries agent uses that to grab the metadata from Youtube.

First, You need a working Metadata Agent that you can get from here this works perfectly fine. Personally, I use the Movies Library type but it should also work with the TV-Shows library type but the following workflow is built around the Movie Library.

I have Plex linked to ZeroQI's YouTube-Agent.bundle and ZeroQI's Absolute Series Scanner.

I personally had issues using these, on plex's end, but hopefully you will have better luck. https://github.com/JordyAlkema/Youtube-DL-Agent.bundle https://github.com/ZeroQI/YouTube-Agent.bundle

I set up the youtube add-on for plex so that it can use my API key to get the video information.

For example, when you have youtube videos you could create a dedicated youtube library and then use the Youtube-Metadata Agent.

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).
