Windows 10: Photo App Video Editor Only Previews Some Video Thumbnails in Storyboard

Hello,Some of the video clips in the storyboard have previews, displaying the first image in the clip, while some do not, and are just black.How do you ensure all the video clips in the storyboard have previews? It's difficult to work with different video clips when you can't look at what they are by glance.Thanks!

Video Editor

I am using MS Video Editor and am working on a project that has both videos and .jpg pics. When I went to open the editor, the project would load, it shows the pics and videos I have loaded into the project, but the Storyboard wouldn't load. It looks
like the app is trying to load the storyboard, but after a few minutes, the app shuts down. I followed the steps online to repair and reset and have now lost my work, but I want to be sure the app is working properly and there are no issues with it before
I start and rebuild the project. Also, the app autosave my work, where does it put the saved Storyboard file?

Video preview thumbnails

Hello,

System file corruption is one of the possible reasons why thumbnail preview has recently disappeared. To better assist you, please answer the following:

• For clarification, are referring to video preview thumbnails when using File Explorer?
  
• We would like to verify if you are referring to the Fall Creators Update. To see your
  Windows build and version, please follow the steps in this
  article.
  

In the meantime, we suggest creating a Test User Profile. This is to see if the same issue occurs on a different user profile.

To create a Test User Profile, follow these steps:

• On Search, type Settings then hit the
  Enter key.
• On Settings window, select Accounts.
• Select Family & other people.
  
• Select Add someone else to this PC.
• Name the User Profile as TEST.
• Assign a password for TEST user, then select Next.
• Sign in TEST user.

We'll be waiting on the results.
