Advanced, Hidden Server Settings - GenerateBIFFrameInterval

Server Version#: 1.29.2.6364
Player Version#: N/A
I am running Plex in a docker container on Unraid.
I had added GenerateBIFFrameInterval to my preferences.xml file about a month ago and enabled thumbnail generation. I have a large catalog, so I didn’t want it to fill up my cache drive, which has happened before and tanked my database.
I found several threads about adding GenerateBIFFrameInterval to the preferences as a “hidden” option and supposedly this was going to reduce the amount of space used by thumbnails. I also found this option on a page on the plex website: https://support.plex.tv/articles/201105343-advanced-hidden-server-settings/
Yesterday my cache drive was about full, so I disable the thumbnails on my TV Show library and deleted existing thumbnails. I went back into my preferences.xml file and there was no GenerateBIFFrameInterval option there. I thought it was strange, so I added it again (GenerateBIFFrameInterval=“10”) and restarted the container. When I went back in to make sure it was there, it has once again been removed after the restart.
Do the Advanced, Hidden Server settings not work anymore? Am I adding it incorrectly? I added this option at the end like
ButlerStartHour=“1” ButlerEndHour=“5” GenerateBIFFrameInterval=“10”/>
To clarify, the Butler options where there, I added the generate option after them and before the closing tag.
Thanks!

Those options should already exist in the xml file. You shouldn’t need to add them to the end of the long line of variables. Also, verify your quotation marks are correct.

You need to use:
GenerateBIFFrameInterval="10"

This will not work:
GenerateBIFFrameInterval=“10”

Summary

My quotes are correct. This forum (or perhaps when I pasted from notepad++ where I type long stuff out) changed them to the “fancy” quotes.
And no, I have several installs of Plex and the GenerateBIFFrameInterval does not show up in my installs by default.
Thank you though.

Unraid’s File Manager UI looks to have used the incorrect quotation marks. See following post.

Ok maybe you were correct with the quotes.
On Unraid, I can browse to the file using the UI. That’s where I added it this time, so the File Manager in Unraid could have change the quotes.
This time I accessed the file directly and added it with Notepad++ and it seems to have stuck.
However, this is how I added that setting to begin with, using Notepad++ directly. Maybe I mispelled the setting the last time, but I swear I copied/pasted.
I will open a new thread if it disappears again.
Thanks for helping @jasonsansone

I have the problem all the time. Apple (macOS, iPadOS, iOS…) likes to change quotation marks to fancy quotes. It royally screws up any linux coding.

Yeah, I tend to code on Windows for that very reason. I do a lot of coding for work and used to use a Mac. It’s all nice and pretty, but terrible for any kind of coding. I just never thought a server UI would use them lol.

For future ref, there’s also this 3rd. Party tool:
