While if you're into serious 3D rendering, CAD, you're probably using a workstation with better GPU, not a laptop. So the graphics card on Macbook Pro/Air, Mac Pro is relatively in low-end. Apple is not offering gaming machines, or even trying to. And MPlayerX does much better job for this particular video, which plays 4K at 22-25FPS, but still not 30, not to mention the 60FPS 4K video recorded by iPhone X, iPhone 8/8 Plus.Ĥ. As you play the 4K video on IINA with this setting, the 4K video player only needs about 300% CPU to decode, other than the above mentioned 700%. Anything above that is just a waste of storage and space on your Macbook Pro/Air, Mac Pro. I find that 1 pass VBR 12Mbps good preset (medium setting) in Adobe ME is very good in general. The GPU is not doing the work, the CPU is.ģ. For example, for the initial question, according to the publisher, when playing 1080p uses about 130% CPU usage, where these 4k h265 files use about 700% on a QuadCore. If the CPU usage is too high, you will fail to play 4K video as well. Even if you've updated to the HEVC compatible High Sierra, the 4K video won't be played smoothly.Ģ. But you know what? HEVC is a hard codec to decode and only the new CPUs are acclerated for it. An increasing number of people encode 4K videos with HEVC codec for saving up to 50% storage space compared to H.264. Check the possible reasons of 4K video playback failure.ġ. Other hardware and video itself are also critical. But it doesn't mean that you definitely can watch Ultra High-definition videos with the 4K external displays. Firstly, except the new 4K Retina 21.5-inch iMac and the 5K Retina 27 inch iMac, no Mac can play 4K 2160p videos without the help of 4K external displays using either the built-in HDMI port and/or using Mini DisplayPort adapters via Thunderbolt.
