True, just I mainly use my computer exactly for videos and encoding is crucial part of it
wished my GPU was better in handling the HEVC, will see

I have a 2011 MBP 15 with AMD 6770m. I think expecting it to perform well with HEVC is a little out of its shelf life. Considering the codecs (even 8 bit) aren’t supported by the hardware at all.
I also have a 2016 MBP 13 with TB. This comes with 8 bit HEVC support.
I have been able to play HEVC ever since the very first HS Public Beta. Works just fine in Quicktime.
However, you need the right format and container. And to play it well, you need the proper Intel GPU for 4K (6th gen for 8-bit and 7th gen for 10-bit).
I haven't test it yet, but I don't think QuickTime work with MKV, you may have to remux it into MP4.
You are doing it wrong.
If you use the later Handbrake nightlies and encode to hcv1 with the right settings, the HEVC files work just fine in Quicktime on 10.13.
Dunno what the latest release Handbrake version includes, but the files must be hcv1 HEVC, not hev1 HEVC. Older versions of Handbrake were only hev1 HEVC AFAIK.
You were right what? Did it work for you or not?
Like I said, Handbrake nightlies can encode HEVC files that work fine in 10.13 Quicktime.
Handbrake 1.0.7 does not create the files Apple expects, so you need to download the "nightly" versions. Those are not called "betas" but yeah it is a sort of beta. You could wait for a new stable version, but for me they are usually stable enough for my use.
Still no HEVC GPU decoding in High Sierra GM. Apple can go **** themselves. They do this again and again and again with their **** drivers. I'm not buying a machine from them again if they don't want to write drivers to support all the features of the overpriced hardware and I had enough of that Craig Spaghetti goofball and his idiotic presentations and terrible OS leadership. Biggest loser in tech.
So what Mac hardware does support HEVC? Polaris and Coffee Lake? Has Apple disabled the software option from those who don't have a sufficient hardware? If so, only 2016 MBP and 2017 iMac's are capable of running HVEC?

Any Polaris GPU does. In Boot Camp using the Radeon driver Apple provides you can play highest spec HEVC beautifully.
As of Beta 9 (haven't tried GM yet), HEVC 1080p60 content plays admirably in QuickTime Player as far back as my 2012 MacBook Air.
In fact, QuickTime performs even better than VLC. Not sure if Apple's decoder is taking advantage of Metal, which is supported on 2012-and-up Macs, but that would be an interesting thing to investigate.

What HEVC 1080p60 content? For example, it seems that the stuff recorded on the iPhone 7 is a lot easier to decode than a lot of demo videos (even 8-bit ones) out on the internet.
Also, what kind of CPU usage are you seeing, and with what specific equipment? But yeah, I wouldn't worry that much about 1080p60. It's the 4Kp60 stuff that is the killer. My 2009 13" Core 2 Duo 2.26 GHz will choke on some 1080p HEVC content though.

My 2016 15" Pro plays 8-bit 4K HEVC just fine in High Sierra. 10-bit plays but is very stuttery.
(10-bit plays flawlessly in Boot Camp since it uses the GPU's hardware acceleration, but High Sierra does not.)

For h.265 HEVC, a better player than vlc (for files Quicktime doesn't support) is IINA.

I previously said that for some 1080p HEVC my 2009 Core 2 Duo 2.26 GHz has problems. While that may be true, with IINA and High Sierra, it seems to do reasonably well with a lot of 1080p24 or 1080p30 material, albeit with high CPU usage.
I actually should put an asterisk on this!
10-bit HEVC with a modest bitrate and framerate actually plays okay - I tried a 30mbps 24fps file and it played smoothly. I tried an 80mbps 60fps file, however, and it choked. I'd bet the 2016 Pro could probably do, say, an iTunes digitally-downloaded 4K movie as-is.
I've been doing some testings. These are some of them.
If anybody want me to run some other tests on my system, I'll be happy to do it, please let me know.
I'll do the same testings after 25th on High Sierra for comparison and will upload it here too.
4K is ****ing amazing.

Note it would be good also to try this again in High Sierra with QuickTime and IINA.
Also HEVC 4K 8-bit. I noticed all your 4K was 10-bit and all the 4K 8-bit was h.264.
My idea was to check how well my laptop handles ultra high definition media. Most of the HEVC video I found online are 10bit. I thought I should try with 10bit since mine is kaby lake with 10bit hardware decoding support for HEVC. If (when) it has 10bit support, it shouldn't have issue for 8bit at all.
When I get my hands on a 2016 MBP Tb, I'll try with same bitrate HEVC for 10bit vs 8bit to check how it handles - in Sierra and High Sierra.
