I have a Samsung phone and I use the default camera to take videos. Then, in my home wifi, I transfer the files to my server using syncthing. The folders where these files are stored is then mounted on a different computer via lan (my main machine). The videos on that machine don’t always have thumbnails and I’m not sure why. How can I track that down? At what stage should the thumbnail be generated?
Technical information (based on questions that I am asked):
- The files are mp4
- I’m using kubuntu 24.10
- I’m using Dolphine file browser
Solution
On dolphin go to settings -> preview -> file size for remote storage.
In this scenario, the thumbnails are going to be generated when you browse the directory. Probably what network filesystem you’re using. Alternately, maybe there is a maximum file size on previews? I know dolphin has that option.

it’s likely this, the mp4s don’t have thumbnail embedded and dolphin is skipping the big ones
Yes! This is it. Thank you!
dumb dolphin thing I forget every couple years, F12 toggles thumbnails on and off
omg thanks for this
Windows 10/11?
These settings don’t do what you want?
What format are the files? What are you using to view the thumbnails?
Important questions, I’ve added this to my original post:
- The files are mp4
- I’m using kubuntu 24.10
- I’m using Dolphine file browser
try installing ffmpegthumbnailer and see if that works after reboot / relogin, if not uninstall and try another method
