There has been a lot of talk about the thumbnail issue on network shares. To re-cap; when a .jpg file with the same file name as the video exists (excluding the file extension) in the same directory then 2 (two) thumbnail images appear. Yes this is (WAS) frustrating to me, until I tried something new, last night. I don’t take credit for the idea, I got it from reading one of the other posts here on this forum.
Here’s the solution (that worked for my setup)
Given that the thumbnail image file matches the video file…
the above would generate 2 (two) thumbnail images, one for the actual .jpg file and one for the move.
Simple putting a PERIOD (.) at the very beginning of the .jpg file name causes the thumbnail for the .jpg to disappear while leaving the correct thumbnail for the video file. The PERIOD (.) at the beginning of the file name, in Linux, marks that file as a “hidden” file.
… results in the correct appearance on the screen.
Hopefully this will work for others…
