HEVC/H.265 10-bit hardware encoding - possible with Intel Quick Sync in Premiere Pro/AME?

I've done a lot of searches and reading for the answer to this question, but can't find any concise answers, so I hoping someone in this forum can help.

 

Is there any system configuration + software version on Mac or Windows that allows 10-bit hardware encoding of HEVC/H.265 with Intel Quick Sync from Premiere Pro/AME?

 

There should be plenty of systems that have the CPUs supporting HEVC 10-bit Quick Sync encoding, but from what I've read it doesn't seem to be available, and I can't find anywhere that explains if it is an operating system issue or a Premiere Pro/AME issue, so I would appreciate it if someone can clue me in on if it's possible or not.

 

Cheers,

Gavin

I'd be very interested to hear any thoughts on this too. 

 

As is often the case with Adobe, the chance of hearing anything from them is slim to none, however I can confirm that as it stands (dec 2020) 10 big h265 files from the A7SIII do not utilise quicksync in the current version of premiere pro cc. I won't be buying an A7SIII until it does so I really hope Adobe can implament this soon.

I think some of the newer 10nm mobile CPUs have a better IGPU and a Quick Sync revamp. That being said I don't know if they will support all H.264/265 variations. I imagine all CPUs in 2021 will.

Seventh generation and above Intel processors have Quick Sync H.265 Main10/10-bit encoding/decoding acceleration support, so it should have been possible for the last 5 years or so, unless there is something I'm missing that would prevent Adobe from making use of this in the older processors? Maybe there needs to be better support from Mac/Windows?

It might not support all 10 bit variations (4:1:1, 4:2:2, 4:2:0 etc). I think AVC and HEVC can support 4:4:4 chroma sampling but I am not sure in Intel's Quick Sync can.

Ah right that may be part of the issue then. I just had a read on Wikipedia and apparently 10th gen processors have HEVC 4:2:2 and 4:4:4 Quick Sync encoding/decoding, so probably not that common yet.

Hi Gavin,

I've been told, "anything is possible with software." So, I think it is possible and hopefully Adobe engineering will add that as a feature as soon as possible. You can certainly make a feature request for that here.

I am not aware of what other NLEs can do in this regard. Maybe someone else can chime in. I can also move this post to the hardware forum, if you like. 

Thanks,
Kevin

Yes, from what I've read it "should" be possible, but I don't know enough about that stuff, I'm just assuming that for now it's not popular enough for Adobe to spend time and money on it...
