What Is HEVC?
HEVC (H.265) is a video compression standard successor to AVC (H.264) and firstly released in June 2013. Offering better data compression ratio, it delivers improved video quality at the same bit rate yet smaller file size at the same level of video quality than H.264 leading it to support ultra HD resolutions, like 4K and 8K. So far, boatloads of encoders and decoders are published to achieve HEVC encoding and playback. Also, some operation systems, e.g. Windows 10, Android 5.0 or later, start supporting HEVC to play 4K and 8K videos with sharper and clearer images.
Does macOS High Sierra Support HEVC?
High Sierra is the 14th generation of macOS which was announced at WWDC 2017 in June and will be publicly released in the fall. Apple had released several public beta versions empowering users to experience this system.
It is confirmed that HEVC is fully supported on macOS High Sierra helping play and stream 4K/8K videos encoded with HEVC natively. HEVC hardware acceleration is also available but requires a Mac (iMac/MacBook/MacBook Pro) with a 6th generation Intel processor or newer.
How to Play HEVC on macOS High Sierra?
From above-mentioned, we can play HEVC on macOS High Sierra natively without any other 3-rd party HEVC codecs installed. Open QuickTime > drag and drop a HEVC video into it and the video will be automatically played. However, HEVC not playing issue still occurs:
“I am using a MacBook Pro while running the macOS High Sierra public beta. I converted a video to the H.265 codec in HandBrake, and I cannot get QuickTime to recognize the file. Does anyone have a potential fix?”
