Windows 10: .mp4 thumbnail icons!?

Did the feature update this morning and now I don't get thumbnail previews for .mp4 files only!


Any idea why anyone!? I like my thumbnails!!!


Chuter.


EDIT: To be more specific it seems it's only not going to show me the .mp4 video thumbnails for the videos that came from my MotoZ2 play device which are in 4k. if that may have anything to do with it?

Explorer Thumbnails not displaying movie icon for MP4 files

I'm using Windows 10 and have noticed for a while that a lot of my MP4 files do not display show that a file is an MP4 file in Explorer.

I view the files using Thumbnails, not icons, and usually view as Large Icons or Extra Large icons.

Some MP4 files clearly show that they're a film as they display the movie style thumbnail, but others just display a plain thumbnail so don't look any different from JPG files.

I've now realised that films that I've taken horizontally with my phone show as movie style thumbnails, but films taken vertically with my phone show as ordinary thumbnails. Here's a screenshot of what I mean.

Can anyone help please?

Thanks.

 

Thumbnails no longer generating for .mp4 files

I recently installed and uninstalled a bunch of programs (which I believe caused the issue).

Afterwards, for some reason, only .mp4 files will no longer generate thumbnails in the explorer. Any new .mp4 file I create now shows up as a default blank thumbnail. Existing .mp4 files (before the issue came up) still retained their thumbnails. All other
types of files are showing up fine.

I deleted the thumbnail cache, and all thumbnails regenerated except .mp4 files.

Does anyone know how to fix this issue? Thank you.

 

Icons for PNG files shown in Windows Explorer rather than thumbnails


Hello All,

After uninstalling software which allows the user to view 3D files (as well as most image/movie files), I could not get thumbnails to show in Windows Explorer for PNG and MP4 file types. I figured that since I was going to upgrade to Windows 10, I would allow said upgrade to "fix" the issue for me.

After upgrading to Windows 10, I could see thumbnails of MP4 files, but not PNG.

Things I have done to get back the PNG thumbnail generation:

1. Rebuilt Icon Cache
2. Cleared Thumbnail cache
3. SFC /scannow
4. Scheduling a check disk to run on boot (both options for fixing stuff were checked)
5. Enabled Thumbnail Previews in Folder Options
6. Enabled Thumbnail Previews in Visual Effects
7. Tried every option from here: https://www.tenforums.com/tutorials/5...dows-10-a.html
8. Reinstalled Windows 10 upgrade.

Nothing has helped. Still icons, no thumbnails for PNG files.

Anyone have any insight as to how I might get back PNG thumbnails in Windows Explorer?

Thank you,
