None of those apply. I have turned off the chapter thumbnails and videos previews, nothing is being synced anywhere, and there is nothing set to optimize, and yet this continues to turn using up 95% or more of the CPU on my NAS and making it impossible to play content.

I’ve killed the process, but it restarts within a minute or two.

This sure looks like it’s creating a thumbnail. though why this is taking many hour to complete is a mystery.

Yes, this is a video preview being generated.

Where/How did you turn the preview thumbnails off?

In the Settings => Server => Library => Advanced preferences.

(BTW: I know this is off because every time I update Plex it turns these settings back on, so I am used to disabling them every. single. time.)

It appears that disabling them is not enough, you have to disable them, stop plex, and restart it. At least so far, it has not resumed them.

This is annoying because I like to turn these on manually when I know the server is not going to be used for a long period, and then turn them off. I guess I have to add “stop/restart Plex” to that workflow. And, in the above quoted process, it had been processing that single file for over 2 hours.

There is a second place to disable preview thumbs:
in the properties of each single library, on the ‘Advanced’ tab

Maybe this one “sticks” better.
