Question about Video Metadata

[gpspam]

I need some help understanding how metadata for videos is scanned/scrapped/generated. I have some videos I downloaded from YouTube that I am adding to my library. When the video gets scanned, a new local metadata file is generated (I set it that way), with a ton of "overview" information. I do not want that overview information to be carried into Jellyfin, but I cannot find a way to get rid of it no matter what I do.

If you look at my attachment, you can see the "overview" information being added to Jellyfin. From what I gather, it is the YouTube video description of the video I downloaded. I can manually delete this information and then lock the metadata, which will prevent it from being re-added. However, if I happen to move the file, or (in the future) migrate my library, this will, once again be generated when I scan the library for new files. I have tried manually creating a local metadata file, but regardless of what I do, it still gets added to the Jellyfin metadata database file on first pull, even when the <plot> portion of the local metadata file is specified as blank.

Screenshot of the auto generated overview metadata:
   

I am almost certain that this information is embedded in the video file itself (though I can't verfiy it). I am, however, almost certain it is not from the internet, as I have unchecked every online metadata scrapping option in an effort to isolate and prevent this from happening. Is there some tool/program that can help me view this information? Also, is there a way to make it so that Jellyfin doesn't read this information by default. Or, while not related to Jellyfin, is there a program/tool that can allow me to wipe this information out? Some of these YouTube descriptions are like essays, which clutters up the episode interface.

Thanks for helping me out.

The metadata lock does not apply to blank metadata fields. It only locks fields that have something filled.

Any piece of metadata that's left blank will be reobtained if possible on the next metadata scan.

Is it possible to edit the metadata file and add something into it so that it thinks there is something there, but looks blank?

Edit: Also do you know where this metadata is being pulled from? I can't for the life of me figure this out. I've already disabled all the metadata scraping options for everything: show, season, episode, etc.

Its stored in the database, unless you are using NFOs. Which it sounds like you aren't. I supposed you could just put a single space? Not sure if Jellyfin will interpret that as "not blank".
