Hello,
how to convert 4k HDR movies with NVencC and preserve the HDR metadata ?
thanks for help me

Hello

Can someone help me please ?

thank

Hello

Can someone help me please ?

Hi, i don't have HDR sources nor the display needed for HDR and don't use Nvencc either but last test version of Staxrip added an option to keep HDR metaData :

new: option added to the options dialog on the video tab to import VUI metadata like HDR from the source file to the video encoder, this is applied when the source loads like before and since this build additionally everytime a video encoder profile is loaded

This 1.7.0.4 test version of Staxrip can be found here : https://github.com/stax76/staxrip/blob/master/changelog.md

Can't help more than this sorry :/

[foxace]

thanks for you answer, but this do not work on NvenCc.

[Yanak]

Arg :/
Not using HDR or having Nvidia GPU i could not even test, Stax is probably the only one that could answer this then, he did not login since a couple of weeks i think, hope he's fine tho.

how to enable this demux option on newest version?

Hi, Not sure if it's what you want but should be this, in Options :

https://s14.postimg.org/lmflo9tch/76565420171109193126.png

(tied to each templates so you will need to save the template after setting this option to be set for the next times too I think)

this work very well

how to get HDR metadata?

[foxace]

with media info

[ircopdd]

with media info

MasteringDisplay_ColorPrimaries :

R: x=0.680000 y=0.320000, G: x=0.265000 y=0.690000, B: x=0.150000 y=0.060000, White point: x=0.312700 y=0.329000

I do not know what to do

G(0.265000,0.690000) ???

[sneaker_ger]

You have to multiply with specific factors to get from one value to the other. You can find them in the x265 documentation along with an example:
http://x265.readthedocs.io/en/default/cli.html#cmdoption-master-display

0.265 / 0.00002 = 13250
0.69 / 0.00002 = 34500

BTW:
1.7.0.4 unstable test build

thanks you

but VUI metadata no work for nvenc

[Magik Mark]

Hi Stax!

Any update on HDR -> SDR conversion script?

[Zetti]

eac3to v3.33 is released.

MKVToolNix v18.0.0 is released.

[Zetti]

eac3to v3.34 is released.

[Cyberavater]

@stax76 Replace ur f3kdb plugin with this one

the one u added doesn't work check it if ya like.
Also Plz add FineDehalo filter I'm having problem adding it manually.

[craigpro]

hi all, been offline for a while due to my chipset 1155 motherboard failing and couldn't afford a replacement for a while.. anyways - is there still the issue with the recent nvidia driver and nvencc encoding? If yes, which previous nvidia driver should I downgrade to please? thank you.

[daberti]

I'm using StaxRip 1.7 and I'm investigating Intel H264 VBR encoding, with max size being assigned.
On the GUI appear Quality and Compressibility, both at 0, point is: how to run compressibility check?

TIA

Pascal = weighted-P is not working with driver 387.92 and current 388.13

Get drivers older than 387.92 if you want weighted-P for HEVC encoding.

thanks JohnLai! I'll try 385.69

from memory the weighted option resulted in a lot smaller file size but I've been without a PC for a month so I've forgotten what I was testing.

EDIT: yes 385.69 works fine. I'd need to do testing to see the file difference with the weighted-p option but from memory it was about 10%?

Don't forget to enable adaptive quantization and lookahead too.

Another thing about NVENC Weight.P..........if you turn it on for H264 encoding, B-Frame will be disabled. Not a good idea.

Only enable W.P. for HEVC encoding because NVENC doesn't support B-Frame for HEVC.

[Malphie]

Hi,

this is a support thread for StaxRip, when I'm active it's OK to post bugs and feature requests here, sometimes I'm offline for weeks or even months, in that case it's better to use the github issue tracker to ensure things don't get lost.

The official website of StaxRip is on GitHub: https://github.com/stax76/staxrip

Are there any merge code for stax? Merge files option doesn't work for me.

[ENiGMA59]

Hi Stax76 help me please the solution ? thanx in advance :p

yeah I'm encoding with HEVC - I did some testing and with AQ enabled the file size was between 5-10% larger than AQ disabled.

WP is enabled and my command line is like this:

--cqp 18:20:22 --codec h265 --preset quality --output-depth 10 --weightp --lookahead 16 --transfer auto

[sneaker_ger]

That doesn't really tell you much. File size might can be 5%-10% bigger but quality may be 10%-15% better (or not). You need to compare same file size with your eyes.

[JohnLai]

WP is enabled and my command line is like this:

Just enable AQ, the quality improvement and extra file size is worth it.

I noticed you use CQP mode, why not pseudo CRF mode? (It is VBR-Target Quality mode, but I have difficulty in explaining it)

Take a look on the setting here
https://i.imgur.com/k9Shlwr.png

You will notice there is less "banding" or blockiness on scene with dark background compared to CQP mode.
Trust me on this. :D or.....test it yourself.


Edit: Because many people complained about weight-p being broken with latest nvidia driver........rigaya@nvencc developer decided to disable weightp option temporary. https://github.com/rigaya/NVEnc/releases/tag/3.25 Thus...stick with version 3.24........

will give your suggested settings a try, I use the staxrip compare function - save a few frames from the same timeframe in source and output file, then do a direct pixel comparison between the two to see how much noise / error / garbage is in the output file.

I'm re-encoding my NAS x264 collection anyways, purpose was to maintain similar 720p quality for much smaller file size.

yes, I know. I am the devil.

EDIT: cannot try your settings as I get an error when processing:

Hmm? You didn't follow the settings exactly.
-.- Where is Initial QP = 1 ? (This one is mandatory as we don't dont want set min QP contraint at default 20)
Nvencc max bitrate for L4.1 is 17500kbps.
For L5.1, max bitrate is 38400kbps

EDIT: You should get something like below. Let us modify it a bit to L5.1 as per BD-ROM-AV-WhitePaper_HEVC.
NVEncC64.exe --vbr 38400 --codec h265 --preset quality --level 5.1 --output-depth 10 --weightp --ref 5 --lookahead 32 --qp-init 1 --max-bitrate 38400 --vbr-quality 27 --aq --sar 12:11 -i -o %source_dir%%source_name%_temp\_out.h265

Many thanks JohnLai!! I haven't had time to conduct in-depth tests as yet but your settings result in about another 10% file size saving over my settings.

Both your and my settings however result in a slight loss of red, particularly noticeable in skin tones WITH static images side by side for comparison. I doubt very much it'd be noticed on a tv watching the show.. at worst the video may look a little ''cool''.

I'm hoping to have time this weekend to do some frame by frame comparisons (staxrip video comparison tool is awesome!) and report back.

Chroma subsampling issue ~.~
Generation loss = can't do much about this.

EDIT: Consider using "--profile main444" to minimize chroma subsampling generation loss. But your output file size gonna...be a trouble....~.~

I need some help I've been searching but I'm not sure exactly what I'm looking for or if it's even possible to do, so i hope there is some smart people here who can help me:)

What I'm trying to do is when i'm muxing I want to have a name on
the audio track with the type of audio it is and channels has and what language it is so I know which one is what.

Normally I see it like this http://prntscr.com/hgypb8

But I wanted more like this
Example

TrueHD 5.1 [Language]
DTS-HD MA 6.1 [Language]
DTS 5.1 [Language]
AC3 2.0 [Language]
and so on

I want to hear if this possible to do it automatically instead of typing it manually
if it is possible how do I do it.

Any help is appreciated

x265 v2.6 is out.

[VincAlastor]

By setting DGSourceNV as Source and hardware cropping filter staxrip's auto crop borders feature uses the wrong values when source is codes in 1088p but displayed in 1080p. This also deactivates the forcing output mod 4 rule for DGDecNV.

How can I fix this? :thanks:

HDR to SDR is very bad, something make it wrong.

http://fs5.directupload.net/images/171204/gyfvj6r7.jpg (http://www.directupload.net)

is it right?

[sneaker_ger]

Those options do not convert HDR to SDR. They only tell x264 what flags to set in the bitstream (players read the flags in order to know how to interpret/display the content). The HDR->SDR conversion has to be done in VapourSynth/AviSynth.

[Marban]

ok, thanks.

How does it work with VapourSynth/AviSynth?

Hey guys. What settings would you recommend using for nvenc hevc for max quality? There are so many and when I try to experiment (like enabling deband, for instance) I usually get errors ;)

So I was wondering if someone would be kind enough to post them .

I've got gtx 1060.

Thanx in advance

PS Should I use these?

https://imgur.com/k9Shlwr

Should I select VBR HQ instead of VBR? What about cabac?

PPS It seems --weightp is still broken in the latest nvidia drivers ;( It makes my encoding process stop at random %

I'm using JohnLai's settings and I needed to downgrade my nvidia drivers to version 385.69 for -weightp option to work. I also have a GTX 1060 6GB GPU (intel I5-2500K CPU).

Dont select VBR HQ with the CQ mode setting, otherwise, you will get full 17500kbps or 38400kbps all the way and ended up with huge file size.

CQ mode only work with standard VBR.


edit: CABAC is the only entropy encoder method that is allowed in HEVC per standard. What with the question? For H264 encoding, nvenc will use CABAC as default

I use the settings like on the image I posted above (found it in this thread), only with VBR HQ instead of VBR and so far it's been working fine.No huge files\bitrates.

Using Staxrip and NVenc and it says my Video Engine is at 97% load on my GTX 1060 but my fans aren't spinning on my video card! Is this normal??

Max temps in the low 60's. Also like the last few you asked what are your 2500 bps quality settings? Staxrip doesn't have a 2-pass mode?

Thanks

I got a feeling that your Initial QP ain't set to 1.........

=.= Let just say NVENCC two pass isn't what you think it is........

MSI GTX 1060? I read it only start to spin the fan once it reach 62'C. There is one manufacturer who set the fan to spin at 65'C too, but I can't remember which. To be sure, try manually adjust the fan speed to verify if it is fan hardware issue. Can't discount the possibility.

Because nvenc chip (pascal) doesn't support B-Frame, depending on resolution/framerate/scene, 2500kbps might be a bad or good idea.....

2500kbps with DVD resolution is fine.
720p 30fps is still acceptable.
1080p 30fps with 2500kbps? Unless it is animation or the content has a lot of static scene......don't bother.

General rule: Follow https://support.google.com/youtube/answer/1722171?hl=en youtube bitrate recommendation, but with a bit twist. Youtube bitrate recommendation is for H264. Since you are using HEVC, well, divide those values by 2? However, since Nvenc chip doesn't support b-frame, so....better set 60-70% of youtube recommended bitrates/resolution/framerate.

Yup...didn't I type that version in the screenshot? As far as nvidia concerned, it is fixed in their bug report database. I kinda lazy to report/inform the issue still exists. Anyone wanna inform nvidia instead?

How is it different than x264 two pass?

Copy paste from afterdawn and Nvidia documentation

x265/x264 multi-pass
The video encoder analyzes the video many times from the beginning to the end before the actual encoding process.

Nvenc
In 2-pass rate control modes, NVENC estimates the complexity of the frame to be encoded and determines bit distribution across the frame in the first pass. In the second pass, NVENC actually encodes macroblocks in the frame using the distribution determined in the first pass.

The video engine chip inside the GPU, is a very small piece of hardware compared to the whole GPU chip.

So, even after using that chip to 100% for hours, don't expect to push GPU Temps high enough to trigger the spinning of fans, especially in winter and inside a cool case.

The behavior of your card is normal.

NVEncC supports only 8 bit for AVS input. If you must use DGSource then you can use VPY input.

Also, it would be worth asking Rigaya if he can support full depth for AVS input.

Yes, I must use DGSource
