After updating to High Sierra I see no change in how H.265 videos play. Apple Promised hardware support on 2016 MacBook Pros in their Keynote. Does anyone know have any info on this issue? I have a fully loaded MBP 2016 15"
 
Some, but not all, 8-bit h.265 4K hcv1 mp4 HVEC should work fine in QuickTime on that machine.

hev1 flagged mp4 HVEC files won't work.
10-bit files will stutter.
mkv files won't work

If you're trying to play a 10-bit file, you're out of luck, because your machine is not supported by Apple for 10-bit 4K HEVC hardware playback.

Yes, I was trying to play 10bit Files. Didn't the keynote specifically say H.265 10bit?

They said that 10-bit HEVC hardware playback requires 7th gen - 2017 MacBook or MacBook Pro. I can play them just fine with my 2017 MacBook Core m3 with under 25% CPU usage.

However, the 2016 (6th gen) MacBook Pros are out of luck. Software only for 10-bit. Yes, the 2016 would get hardware acceleration, but only for 8-bit.

This was laid out all very clearly by Apple. So, that AppleInsider article is pretty misleading.

Thanks for clearing it up. If my display was 10bit and I had a 10bit work flow I would be very upset. Since everything is still 8bit it’s not that big of a deal yet.

Whats the usual bit that 4K comes out in?

iPhones video is 8-bit.

Streaming video is 10-bit or can be 8-bit. However, it should be noted that there is no streaming 4K at all for Macs. And if it does come out for Macs, my expectation is that regardless if it's 10-bit or 8-bit, it will require a 2017 or later Mac anyway, for DRM reasons.

Sorry for asking the same question in another post.

The HDCP 2.2 right? That is also quite a stir.
The 2016 MBP is kind of like in the middle of a transition period isn't it? A mistake to buy!
