Re: [HELP/REQ] 2-pass QSV a

Can you post your logs as it would be nice to see what the bitrates are when you compare x265 to QSV. I made several tests 1 year ago. Overall I would say CQP FF is a bit under x265 medium and CQP GPU a bit over x265 medium at the same bitrate, fully cranked up CQP of course and this is a rough est...

Re: [HELP/REQ] 2-pass QSV a

In the past time I've been busy with QSV and searched all forums for information. Finally I arrived at my goal and encoded different samples with different hardware. I have tried every possibility with a UHD 630 in every respect and in the end you will not achieve good quality with this hardware wi...

Re: [Nightly] Low Power QuickSync Hardware encoder

low power means fixed function, so it only uses the fixed function unit for encoding which uses less power. Without FF/lower power it's a hybrid, it can use some GPU resources like execution units, in this mode there is more flexibility/quality but also uses more power. Up to Gen9 graphics (Skylake-...

Re: H.265 QSV Encoder Fails with v. 1.3.2

Low power H265 encoding is not supported for Skylake or Haswell, this is only supported for H264. Icelake is the first generation with support for H265 low power encoding.

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

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 ...

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...

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

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...

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...
