madVR - high quality video renderer (GPU assisted)

[huhn]

the number of "cores" is only comparable in the same architecture at the same clock. nvidia turing and pascal card reach easily 1800 mhz out of the box a vega 56 or 64 can't do that.

the new turing cards can do a lot of "maths" types a lot faster we talk about stuff like x128 faster here then older generation GPUs.
if stuff liek this get's utilized the newer turing cards will run exclusive stuff only they can do and/or do it faster.

so there is a simple solution to this problem. if you don't need a new card don't get one and wait when this "stuff" gets used.

I use this to change 3dlut with the TV device, note the lowercase names:

if (HDR) "hdr"
else "sdr"


I could not get madVR to detect content properly based on (HDR) or (hdr). With (bitDepth), it will differentiate between 8-bit and 10-bit content, which in return will switch the TV into proper HDR mode when playing HDR content. Another workaround ;)

I'm wondering why you use (HDR) to swap LUTs, though. You have a non-HDR display, so wouldn't having a separate LUT for each color space do the trick? I use DisplayCAL to create LUTs for each SDR slot in madVR, and madVR picks the appropriate one depending on the source.

The variable is capital HDR. :) It works for me (OSD reads the filename of the used 3dlut). Which madVR version do you use?

Not because of that but because HDR pixelshader needs gamma 2.2 3dlut all the time (with current madvr test builds), as I was told :) , otherwise I use gamma 2.4 during the evening with sdr content.

I thought that's why you did it that way. You really need to upgrade your old LG. I had the 60" 550 from 2011 - 2013 :D *Just checked the old AVS thread, and I bought it back in 2010 LOL

I use the latest available test version of madVR. Same for LAV, MPC-HC, etc.

Thank you so much.. This makes complete sense.. Maybe it's time I gave nividia another chance

Currently I don't need a new GPU, however the reason I am making enquiries is because I can return my RX 580 to amazon until the 17th march for a full refund.. After that I'm stuck with it until I want to really upgrade..

I'm happy with it but I was wondering if its would be wise to get a refund and replace with a rtx 2060? That's what I was wondering.. And if so.. Is there a specific 2060 model that is recommended? Asus Strix comes to mind but I may be wrong.. Thanks

[blackjack12]

In my experience, the D3D11 hardware decoder is much more efficient when used correctly. Especially with internal Intel GPU's (like the 7 series and up). It allows 4K, HDR material to be played with no issues where any other setting does not.

madVR has produced the best video and color quality across the board when used with MPC-HC and MPC-BE as tested ...

madVR currently does not support interlaced formats with the D3D11 decoder ... deinterlacing with madVR and DXVA2 works very well.

Apologize if this has been addressed earlier, but have not had time to search the entire madVR site.

Any idea when/if interlaced formats will be supported by madVR with the D3D11 decoder?

Hello,

Is it possible to use DXVA resizing for chroma when LAV is in software mode ?

I explain in MadVR (scaling algo/chroma upscal) I can not select DXVA, it works if LAV is in DXVA/DXVA Copy-Back mode but not in software mode.
The problem is that in H265 my card is not able to decode more than 1920x1080 (and not all) so for 1440p or 2160p this is not possible ... no problem the CPU gets there ... But no algo for chroma (in scaling algo/chroma upscal) does work so I can not look at native resolution !

For example a film in 1440p x265 10bit HDR seen on my screen (in 2560x1440) even in Bilinear Chroma resizing, there are lost frames (MPC HC x64) :
https://i.goopics.net/GQpr3.jpg (https://i.goopics.net/djLWO.jpg)
https://i.goopics.net/djLWO.jpg

On the other hand the same film 1440p works perfectly on my screen (in 2944x1656) but resizing chroma and image DXVA (MPC HC x64) :
https://i.goopics.net/VxoWZ.jpg
(https://i.goopics.net/wEv2y.jpg)https://i.goopics.net/wEv2y.jpg

When there is an upscale or downscale of the image (luma) then DXVA is also used for chroma (LAV in DXVA or Software). On the other hand, when there is no resizing of the image (luma) and LAV is in Software mode the Chroma does not use DXVA ...

Even a movie 3840x1606 x265 10bit HDR seen on my screen (in 3104x1756) with DXVA (chroma and image) resizing work well (MPC HC x86 + Reeclock) :
https://i.goopics.net/a2pWe.jpg (https://i.goopics.net/eP7WP.jpg)
https://i.goopics.net/eP7WP.jpg

But impossible to put in MPC Video Frame/Normal Size ... Chroma upscaling is texture unit or pixel shader ...


Is there a solution ?

I would. I'd probably pick the first card from ASUS, MSI or Gigabyte that a user says has little to zero coil whine.

@vanden
if you set upscale and downscale to DXVA and chroma to bilinear you should get DXVA for everything.

known limitation but no kown ETA at all.

Can someone please tell me if I calculated the nits for my screen correctly please for using the target in madvr dynamic tone mapping.
My screen is a Studiotek curved microperf 145" diag with a gain of 1.2

I took a reading at the screen using 100% white, meter facing the JVC NX9 which was on half lamp.
The reading was in F.C. result 17.5 average over the scope screen with Isco IIIL lens in place.
I then converted FC to FL by multiplying by the screen gain 17.5 FL x 1.2 gain = 21 FL

Then converted FL to nits 1FL = 3.4263 nits
Result 21FL = 71.95 nits

Have I dont this correctly. so I use say 71nits for my target in madvr tone mapping?

I dont need to use the size of the screen in the calculations???

Well after you load your 3D lut, just go by eye, because a number doesn't really help here, it's a To-Taste situation.

Freeze frame at scenes with HDR highlights, and tune it up or down until YOU like it.

Then try a few other scenes.


NX9 looks expensive. are you planning to buy a spectro to go with it ?

[chros]

You really need to upgrade your old LG. I had the 60" 550 from 2011 - 2013 :D *Just checked the old AVS thread, and I bought it back in 2010 LOL
I also bought mine in 2010 :) The HDMI chip on its mainboard (the "only" thing that I use :) ) died 2 years ago (others had the same issue at that time!), I baked the mainboard in an electric oven and it was good for 2 months, after it died again :D I found only 1 mainboard in 1 online shop out of 30 worldwide, I bought it, replaced it and it works again. :)
I had been playing a bit with the thought of replacing my TV but after I learned more about current HDR implementation I decided not to. I'll use this TV until it lasts and I spend my money on anything else! :D

I use the latest available test version of madVR. Same for LAV, MPC-HC, etc.
Strange, then I don't know why HDR variable doesn't work for you with that setting.

Maybe Madshi goes AMD in the future because Vega 7 has some sort of advantage given its HBM ram. Or some other feature set.

We can't buy a graphics card , "betting" that madshi will implement some use for it in the future.. Because no one knows if that will happen, not even madshi..

If you need a card, at this very moment, 1070/1080 gtx seems to be the performance lvl necessary for NGU chroma + HDR tonemapping

If you're not NGU obsessed 1050ti and 1060 will be fine.

I saw used 1050ti from evga for ~$90

used 1060 is tough, because there are lots of bad models, but good models usually go for $170-180. it got more expensive recently after the amd announcement of no competition for that bracket.

I agree with you in this, especially with these insane GPU prices. It's not just about the money for me but principles.
And that's the good thing about HTPC that you don't have to be future proof but only buy a new (used) card when it's absolutely needed.

Then I hope my current TV will last another 10 years! :D

@vanden
if you set upscale and downscale to DXVA and chroma to bilinear you should get DXVA for everything.

Alas not at all !

See my screenshot : I can read a video 2560x1440 420 resized by DXVA (chroma and luma / resize in 2944x1656 / GPU @ 65-75%).
But I can not play a video 2560x1440 420 in native resolution (resized in 2560x1440 only chroma Bilinear / GPU @ 90-100%) ...
Ditto : I can read a video 3840x1606 420 resized by DXVA (chroma and luma / resize in 3104x1522 / GPU @ 60-70%).

Sounds about right, provided the screen gain is actual and not advertised. My advertised screen gain is 1.3 (Carada BW), actual is just above 1. I think you only need screen size to calculate lumens.

So yes, 71nits for the target in HDR pixel shader is what you can use, but there are other settings that have a strong impact on the picture brightness.

At present time your statement is just wishful thinking. I would accept bets that all this year independent shootouts will be won by an OLED TV.
Now, considering that discussion of competing TV technologies is kinda off topic here, would you please refrain from similar comments in the future? They're pretty much useless.

I wish I could use in MadVR DXVA resizing for chroma upscaling ... just to be able to play my movies in native resolution (ie to be able to watch a 1440p movie on a 1440p screen or a movie 2160p on a 2160p screen)

I saw your posts about it on AVS :) I used to be very active in that thread. My mainboard broke shortly after I had replaced the 550 and given it to in-laws. Those models were notorious for doing that. At the time, I would not have thought I'd buy another LG anytime soon, but here I am with my OLED :p Great to hear that yours still works. Was a good TV at the time, unlike anything non-OLED from LG right now :D

[el Filou]

@vanden Workaround for you: in the settings of LAV Video, uncheck all the 4:2:0 and 4:2:2 output formats. This will force LAV to do the chroma upscaling itself in software. It will also convert to RGB, it won't output 4:4:4 YCC.
Of course this will probably be lower quality than madVR's own processing, but your GPU is in way over its head with madVR's HDR tonemapping.
Also for HDR10 with that setup, LAV will still output RGB32 unless you uncheck it and force RGB48 but I don't know which of those is the best for madVR.

Unfortunately I'm not sure it's even possible to use DXVA only for chroma upscaling if you're not also using it for decoding, deinterlacing, or image scaling (maybe madshi can give more information on this).

[ryrynz]

Its a Mid-2019 screen without HDMI 2.1, so better to pass anyway.
Maybe next year we'll finally get complete screens without tech shortcomings like that.They saw no real need for it. They said you can add the 2.1 featureset to 2.0b anyway.
Just a shame we still haven't got 120hz display refresh.

[nevcairiel]

They saw no real need for it. They said you can add the 2.1 featureset to 2.0b anyway

I see a need for it, specifically when running a HTPC, because the bandwidth of HDMI 2.0 is just too low - and thats not something you can add without a HDMI 2.1 transceiver.

I want to be able to run at 4K 10/12-bit no matter the refresh rate, which is not something I can do with HDMI 2.0, because 60Hz exceeds the available bandwidth.

Also, eARC, with streaming services also introducing better audio, and many clients for such services being baked into the TV itself.

[ryrynz]

I see a need for it

Yeah same, although we are in the minority of their customers.
LG got you sorted this year.

[nevcairiel]

LG got you sorted this year.

Indeed, and I applaud them for commiting to it.
Although I'll probably only start seriously considering a new TV next year. Finally the tech has caught up, both with HDMI 2.1 and HDR performance, and next year we'll hopefully also see widespread DV and HDR10+ support like that Panasonic has.

[ryrynz]

Would love to see a shootout of madshi's HDR box vs any other TV's Dynamic Tone Mapping, madshi may I suggest providing Vincent Teoh from HDTVTest a review sample once it's available?

[Warner306]

It wouldn't really be a fair comparison because the TV can control its internal PQ scaling and madVR can't. It can only send rescaled PQ values to the display and it is up to the display as to what it does with these values. There would be have to be some sort of mode in the display and some controls to guarantee that the output is displayed 1:1 and not displayed at a different luminance or with any other unwanted color space conversions.

It would make more sense to compare directly with an external processor such as the Lumagen Radiance Pro. Seems like a guarantee that Kris Deering of Sound & Vision/AVS Forum will make this comparison because he is always reading the madVR thread while simultaneously selling Radiance Pro's.

[Warner306]

FYI, Soulnight at AVS Forum started a thread about the Envy. I just saw it today and found some interesting tidbits about people's expectations for this thing:

madVR ENVY: Anticipation thread! (https://www.avsforum.com/forum/37-video-processors/3053602-madvr-envy-anticipation-thread.html)

One limitation not mentioned versus a HTPC is that madVR doesn't have access to the decoded frames. If you used a Nvidia Shield as the source, for example, you would still have to live with the Shield's flawed video output. Devices like the Shield do let you choose different output resolutions for different content, and there are obvious advantages such as accessing a few 4K HDR movies that will never be ported to UHD Blu-ray or 4K HDR Netflix and Amazon TV content.

@ el Filou
Thank you, this is a track until madshi statu on this problem.


For all the tests following LAV is in SOFTWARE Decoding Mode, File 1440p 10bit HDR (MPCHC x64).

If I uncheck P010 in LAV : LAV makes the converssion 10bit->16bit and in madVR I enter in 16 bit 420 (P016) and madVR makes a chroma upscaling in DXVA Mode !!!
I guess the HDR ton mapping is done in 16bit in this case ? but it does not have to be really embarrassing.
it works well GPU stable @ 58% CPU @ 15% :
https://imagizer.imageshack.com/img921/6238/o79YuP.jpg

If I uncheck P010 and P016 in LAV : LAV makes the convention 10bit->8bit in madVR I enter in 8bit 420 (NV12) and madVR makes a chroma upscaling in DXVA Mode !!!
I guess the HDR ton mapping is done in 8bit in this case ? Not ideal if that's the case.
it works well GPU stable @ 55% CPU @ 12% :
https://imagizer.imageshack.com/img923/9442/UcpGTF.jpg

If I uncheck all 420 (NV12, YV12, P010 and P016) and 422 (YuY2, UyUV, P210, v210 and P216) in LAV : In madVR I enter in RGB32 (LAV does chroma upscaling with I do not know what algorithm + convention YUV to RGB).
I guess the HDR ton mapping is done in 8bit in this case ? Not ideal if that's the case.
it does not work well, some presentation glitches GPU @ 79% CPU @ 19% :
https://imagizer.imageshack.com/img922/3079/WpxyNY.jpg

If I have everything checked in LAV : in madVR I enter in 10bit 420 (P010) and madVR does a chroma upscaling using TextureUnits/PixelShader (Bilinear, Cubic ...) and it does not work GPU @ 92% CPU @ 17% :
https://imagizer.imageshack.com/img924/3286/fv9OiE.jpg

If I have everything checked in LAV and screen set @ 2944x1656 : in madVR I enter in 10bit 420 (P010) and madVR makes a chroma+Luma upscaling (2560x1440->2944x1656) in DXVA Mode.
it works well GPU stable @ 71% CPU @ 16%
https://i.goopics.net/wEv2y.jpg


So madVR can use DXVA for chroma upscaling in 8bit (NV12 and RGB32) and in 16bit (P016) but not in 10bit (P010) ! it's very weird anyway !



@ tp4tissue
Yes it is greedy in electricity ...
For noise I modify the system that manages the speed of the fans ... it's really much less noisy.
For the screen it's a LaCie electronblue IV 22" CRT screen.
Support :
2880x2160 @49-50Hz (4/3)
3104x1746 @49-50Hz (16/9)
2944x1656 @49-60Hz (16/9)
2560x1600 @49-60Hz (16/10)
2560x1440 @49-72Hz (16/9)
2240x1680 @49-75Hz (4/3)
1920x1080 @49-120Hz (16/9)
1600x900 @49-144Hz (16/9)
Etc …


Edit :
For all tests following LAV is in SOFTWARE Decode Mode, File 3840x1606 10bit HDR (MPCHC x86 + Reclock). Screen in 3104x1756 and in MPCHC : Video Frame/Normal Size.

All the tests by modifying LAV does not work (NV12, P016, RGB32), example in NV12 :

On the other hand If everything is ticked in LAV (P010) and I put -2% on the zoom in MPCHC (the image is resized in 3766x1576 / via DXVA chroma+Luma upscaling) it goes :

[tp4tissue]

@ vanden.

Even if you get it to play with the lav-tweaks you're doing. We can not easily verify that everything is rendering correctly.

What you can do is, use SDR test patterns, look for banding (gradient), black lvl and white lvl.

If those 3 elements checks out, on whatever setting you've gotten it to play smoothly with, That's as far as can be gotten, without madshi chkn' it out personally, which he's probably too busy for.


The other easier way of course, is Buy a used 1060 6gb, 1070 or a new 2060..

Is your crt calibrated ?

[vanden]

The best solution would be that DXVA chroma upscaling works with 10bit file.

Unable to use a geforce 10 with vga and the adapter DP->VGA are limited to a RAMDAC of 330Mhz ... 2880x2160 @ 50 HZ = 439.6 Mhz ...
For non-probe calibration it is limited...

Does the 650 ti use a 600mhz ramdac ?

Have you tried this Sunix adapter.

SUNIX DPU3000 <allegedly can do pixel clock 500mhz>

You don't need 2880x2160 for movies. use a 16:9 res, and you can do it in <400mhz envelope, The mask probably won't resolve that resolution anyway, it'll just look blurry, I guess some vga enthusiasts argue For the vaseline look @ higher res, buh, clearly the manufacturers don't think that way, otherwise they'd slap the higher native res sticker on the box..

Why does this even matter? Or any of your questions/posts for this issue? :rolleyes:

@vanden described his problem very well and I think for some system dxva scaling for chroma only could be useful. So its up to madshi to change it if he agrees.

The whole point of madvr is to be more accurate, by keeping the unstable/imprecise dxva @ bay.

I don't object to the feature of dxva chroma, but pushing hard for it is going in the opposite direction of quality, madshi is 1 guy, m0ar Ngu development or m0ar dxva chroma ?

Do you guys think this will be a custom asic or fpga ?

Well, the name (eNVY) and the font/color used gave me an idea that if it is a processing box for non-HTPC use, then it might be software running on Tegra hardware - Shield TV (does it have HDMI in tho?) or more likely the newer Tegra modules. They have some GPU power and also lots of neural network acceleration for upscaling use. Not a cheap hardware though, similarly to FPGAs. (What do I win if true? :D )

I don't object to the feature of dxva chroma, but pushing hard for it is going in the opposite direction of qualityvanden has to use DXVA chroma/scaling because he's using madVR for the (very) high quality HDR tonemapping and with his GPU he has to make a choice. I think it's valid., madshi is 1 guy, m0ar Ngu development or m0ar dxva chroma ?That is a false dilemma as the work required to implement/develop those two is very different.

Not exactly. DXVA isn't quite as bad as you make out in many situations.
Sometimes sacrificing chroma quality is actually a worthwhile trade off.

I'm aware of why he's doing what he's doing, and I never said it's invalid.

I did suggest, that the whole chain would have to receive Validation, and that could be quite a while, if it happens at all.

An easier and faster solution is to buy a slightly stronger card with full decode, using a known working process chain.

There's a difference between Not ideal, Not always, and Why.

If the possibility betrays the original intention to --a certain-- degree, we usually solve it some other way. and That's what I'm trying to highlight.

For example, why even use Madvr, why not use custom presenter, it's faster, and you get an image with lower chroma quality lower luma quality, etc.

We use madvr because we want to get the most quality out of the thing, but then now, we hold back the minimal amount of resources that madvr needs to work properly. What was the point ?

SOMETIMES, throwing money at something, IS the best solution, (not the only solution, just the fastest, known/tested and reliable)

lol.
In the exact same post you first say you understand vanden's need:
I'm aware of why he's doing what he's doing, and I never said it's invalid.but then just two sentences later you ask again why bother to use madVR if it's to sacrifice quality here or there:For example, why even use Madvr, why not use custom presenter, it's faster, and you get an image with lower chroma quality lower luma quality, etc.
We use madvr because we want to get the most quality out of the thing, but then now, we hold back the minimal amount of resources that madvr needs to work properly. What was the point ?The point is to benefit from madVR's unique HDR tonemapping, which MPC's custom presenter cannot do.SOMETIMES, throwing money at something, IS the best solution, (not the only solution, just the fastest, known/tested and reliable)Tbh, if he's using a CRT with UHD sources, I'm not sure he's gonna see the difference between DXVA chroma upscaling and a higher quality one by madVR. Are you suggesting he also throws money to change his display?
