Some MP4 thumbnails are black

Some MP4 thumbnails are black what do I need to do to show them all?

Are they also black in File Explorer?

I'm having the exact same issue.

They are normal in Explorer and SearchEverything.

Iv'e tried installing icaros and clearing the cache in Windows, Icaros and Directory Opus.

I notice that the thumb nails don't change to settings adjustments like trying to remove the film reel effect around the outside or changing from square to landscape. I read it might have something to do with some people cache amount in Directory Opus but I wasnt that lucky. Please let me know of a fix soon I work in Multimedia and im going insane.

No. In the same folder 3 of them are black

Since they're working in File Explorer, you should be able to fix them in Opus as follows:

Fantastic! TRhanks
