benja007 If you mean by "view" is the ability to play them. Then be sure you have HEVC Codec installed on your Windows 10/ 11 PC. You can get it from Microsoft Store.
Don't buy the Microsoft's 1 USD garbage one that doesn't even work. Just search the Microsoft Store for : HEVC Video Extensions from Device Manufacturer
Once you find it, Install it and you're good to go, and don't forget to restart the PC after you install it so it can be integrated with web browsers and media players properly.
Hope this helps.
