So I upgraded my Mac to high Sierra and I was about the H.265 video encoding standard but when I encode a H.264 video to H.265 standard and then when I attempt to open the video using quick time player it shows "Quick Time player does not support these kind of videos"

So is this a problem that only I am experiencing or is this expected. I am running latest version of High Sierra by the way.

“All iOS devices running iOS 11 and all Macs on High Sierra will support HEVC playback” https://www.macrumors.com/guide/hevc-video-macos-high-sierra-ios-11

Use QuickTime to encode the video to HEVC/H.265 so you can ensure it is encoded to the correct standards. https://developer.apple.com/library/content/documentation/General/Reference/HLSAuthoringSpec/Requirements.html

I’m guessing you were encoding using Handbrake.
