Just bought a max, most likely I will be returning it as it is too buggy. The Gopro Player wont pick the camera up because windows cant find a driver for the camera, and I cant download a driver for the camera because there isnt one on the website. And when it did kind of work, I needed to install the HEVC codec from Microsoft to play the content. BUT GUESS WHAT, you cant download the codec because you need to have a redemption code. So basically I have a $500 camera that to me is a useless brick. It records but I have to use a cell phone application to view the footage and to edit which is just not acceptable.
Your computer is missing HEVC hardware decoder to read this file. These typically are provided by your computer manufacturer, please contact them to redeem or download the HEVC decoder otherwise you can purchase it from Microsoft Store directly.
