4K video streaming and playback on Mac turn to be a reality for the support of HEVC (H.265) in the new macOS High Sierra. Smaller size (with up to 40% compression more than H.264) lets HEVC videos take up less space on Mac and stream better over internet, while fantastic quality can bring a great visual experience.
It’s great to enjoy a 4K movie on iMac with 4K display running on macOS High Sierra, but if we want to transfer 4K videos from Mac to iPhone, iPad or other devices which can’t accept HEVC for removable playback or compress 4K to lower resolution (1080P) for later editing in iMovie/Final Cut Pro, a 4K video converter is badly needed.
