    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?

        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

            Do a test: copy a bunch of videos directly from your phone to a test folder separate from the current one you use. See if all of the files get thumbnails.

              These settings don't do what you want?

                  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 the file manager is skipping the big ones
