Windows 10: MP4 thumbnail images not showing in Photos

Recent videos in the last few months are not showing thumbnails of the respective video in Photos, just a blank video icon.

:)

 

.MP4 files lose their thumbnails in the Win 10 Photos app, when viewing in "Collection" mode.

First:

Win 10 Home.

Version 1607 (OS Build 14393.576).

Microsoft Photos 16.1118.10000.0.

All available update applied.

Everything, that I know of, works perfectly, except for the following very odd issue with the Photos app.

I power on my pc and then start the Photos app.

I choose the "Collection" option to view all of my files.

Some of my files are .jpg's and some are .mp4's.

Initially, the "Collection" view shows thumbnails for all of my files. Both the .jpg's and the .mp4's.

And this is great.

Most times, I can end the Photos app and restart it several times a day and everything looks good.

But occasionally, when I restart the Photos app, I see thumbnails for all of the .jpg files BUT, instead of having a unique thumbnail for each .mp4 file, I have instead, a grey box, with a round circle in the middle, for each .mp4 file.

I can double click on these boxes and the .mp4 files play just fine.

It's just that my thumbnails have been replaced with these grey boxes.

What always works (to return the .mp4 thumbnails), is to restart the pc.

When the photos app stops showing the thumbnails, if I navigate to the folder that holds the .mp4 files, they all show as little thumbnails in file manager. (As they should.)

It's just the Photos app no longer shows the thumbnails for the .mp4 files.

The thumbnails for the .jpg's do continue to appear in the Photos "Collection" view.

Anyone else have this very odd issue ?

Suggestions would be very much appreciated.

Thanks.

File Explorer not showing thumbnails

Brink,

Many thanks for you reply. I have done all the steps you suggested, but no change,

When I open a folder containing photos, some open correctly but the vast majority open with thumbnails, but they very quickly get overwritten and you can not longer see the thumbnails.

Are there any more suggestions?
