iMovie for Mac update H.265/HEVC support

Following the release of the macOS High Sierra software update which, enables High-Efficiency Video Coding (HEVC) on supported Macs, the Apple has issued an update to iMovie for Mac bringing the ability to import HEVC videos. iMovie version 10.1.7 for Mac adds support for importing HEVC video on macOS High Sierra.

Tips: A fairly modern system is required to do so with hardware acceleration that provides stutter-free playback and optimized battery consumption. If you have a 2017 Mac or later, you can play back 4K HEVC video with hardware acceleration. Mac models from mid 2015 or earlier work with HEVC video that was captured at no greater than 1080p at 240 fps.

From above information and tips, we can conclude that to get the best workflow of H.265 video with iMovie for Mac, there are several strict requirements:
– Make sure that you’ve installed the latest macOS High Sierra OS
– Update your iMovie to the latest 10.1.7 version
– Prepare a modern Mac computer such as 2017 Mac or later to handle 4K HEVC with hardware acceleration
– Old Mac models can only handle HEVC video no greater than 1080p at 240fps
