Check if thumbnail preview supported view is turned on
Before doing anything else, make sure that you have turned on the thumbnail preview supported view for the folder where you have your videos or photos. Note that every folder can have its own view setting, and when you change the view, it won’t be applied to all the folders on your PC.
To turn on thumbnail preview supported view, click on the View tab, and then click on one of the following views:
# Extra large icons
# Large icons
# Medium icons
All the above mentioned views support thumbnail previews. Select on one of the above mentioned views to turn on thumbnail view.

Check if thumbnails are disabled
Even if the thumbnail preview supported view is turned on for a particular folder, thumbnails for files won’t be displayed if the File Explorer is configured to show icons instead of thumbnails. When thumbnails are turned off, the File Explorer displays icons of the default program for the file type instead of the thumbnail preview.
Here is how to turn on Thumbnails in Windows 10:
Step 1: Open up File Explorer. Click the File menu and then click Change folder and search options to open Folder Options. If a file is selected in the particular folder, you might see just Options instead of Change folder and search options. Clicking Options will also open Folder Options.
Step 2: Switch to the View tab. Under Advanced settings section, uncheck the option labelled Always show icons, never thumbnails, and then click Apply button to enable thumbnails in Windows Explorer.
