Re: QuickSync on Ice Lake laptop (i7-1065G7)

mbbrc is very useful for Gen9 and a must have for VBR bitrate mode, you should try it. QVBR is VBR with a target quality level. If there is no option in Staxrip you could try --qvbr and --qvbr-q in the custom field. --qvbr <int> set bitrate in Quality VBR mode. Requires --qvbr-q option to be set as ...

Re: QuickSync on Ice Lake laptop (i7-1065G7)

It seems to work regardless of the feature check which is a good news. On a further note QVBR is supported for HEVC acording to the check which is not supported on Gen9 graphics, this could be interesting. VBR has some flaws and QVBR might bring improvements in this regards. Are you using MBBRC (per...

Re: QuickSync on Ice Lake laptop (i7-1065G7)

Also, when I encode in StaxRip using QSVEnc, mediainfo shows the video to be 10bit on the output file. Interesting. You should convert a sample with 8 bit and another run with 10 bit. If the encoding time is higher with 10 bit and the output differs then it looks like that the feature check is wron...

Re: QuickSync on Ice Lake laptop (i7-1065G7)

Yes it is. Ok there is no 10 bit HEVC for you in QSVEnc says the feature check. Do you get 10 bit in Handbrake? You have to look in the log for this:

H.265 encoder: yes (8bit: yes, 10bit: yes)

Ideally it says yes for 10 bit.

Re: QuickSync on Ice Lake laptop (i7-1065G7)

QSV is not all about speed, it's a combination of speed, quality and low resource usage. Usually Intel improves their QSV in both speed and quality with every new GPU generation. If QSV was all about speed they wouldn't have to improve on quality and would rather focus only on speed which is not the...

Re: QuickSync on Ice Lake laptop (i7-1065G7)

Perhaps in a few more generations, QSV will be on a par with CPU encoding. But then, of course, CPUs are getting faster. This i7 10th gen I have runs about 3x faster than my i5 7th gen for CPU encoding. I'm getting about 30 fps using x265 medium setting. So in a few years, that will probably be aro...

Might also want to make sure you have a monitor attacked to the Intel UHD ports as the QS implementation is still D3D9 for decode, which doesn't allow for inactive devices to be used.

Intel UHD is my secondary graphics at the moment, I'm surprised QSV decoding isn't D3D11 in Handbrake.

Re: NVIDIA Decoding

One big advantage for the hardware encoding is the low CPU utilization, especially for notebooks and slower machines. Without hardware decoding support the CPU utilization will go up, hardware encoding without hardware decoding support is poor. The thing is QS decoding isn't working either for me in...

Re: QuickSync on Ice Lake laptop (i7-1065G7)

Other than the minor performance improvement you note, the Ice Lake changes are for VP9 and YUV formats that HB doesn't support. It's a different HEVC encoder, so the output is different. Intel claims it's faster and higher quality. I wonder if Icelake QS is supported in Handbrake. It needs at leas...

I don't have this issue, HEVC encode is working on my HD 630 with the UWP driver. Hardware decoding doesn't seem to work but this is a different matter.

Re: Having issues enable H265 Quicksync

You have to use another software that supports QS H265 because Handbrake suffers from too many freeze and performance issues. It's known since ages, they don't fix it, any further reports will be useless. And by the way HEVC suffers from a poor scene change performance because of the missing Lookahe...
