Debian 12: how do I get Gnome Files to display preview thumbnails/icons for large video files? Right now it just shows generic icons

Roughly how big are these files, and are they stored locally on your machine or mounted over the network (using FUSE, GVFS, or a kernel-based one like NFS?)

I've noticed a few linux file managers are quite cautious loading multimedia thumbnails for networked filesystems mounted with GVFS, not sure of a fix for that aside from looking for a command line utility to mount using FUSE instead
- These files are anywhere between 600 MB to 1.5 GB in size and thet are stored locally on my PC.
  
  Make sure you have all the free and non-free video codecs installed
  
  Look for preview size in the settings for your file manager and increase it.
Something similar happened to me once and installing tumblerd fixed it.
There should be an option in the setting to choose the max file size for which to generate the thumbnails.
- This is what I see when I open Gnome Files, click on the icon with three lines, and select Preferences (there's no option for choosing the max size):
Through the power of interpretative dance.
