File Explorer MP4 Icons: Why do some display 'cine-film' edging while others do not?

[NatalieHill]

The photo illustrates my point clearly. The 'cinematic film border' is only applied to icons in landscape orientation, not to those in portrait orientation. I wonder why Windows doesn't add the border around the outside of portrait icons or simply not display it at all, even for landscape icons.

Although I primarily use VLC media player, I believe this issue is related to Windows/File Explorer. It may be a legacy feature from the past that hasn't been addressed yet.

I'm interested to know if others have noticed the same behavior. It's not a critical issue, just something that piqued my curiosity.

Different types of media files are often represented differently in Windows due to their content. It’s possible that Microsoft designed the film border specifically for landscape videos because it resonates more with how most users visualize movies and cinematic content. For portrait videos (often seen in social media formats), the lack of a border could reflect a different classification or intended use.
