madVR - high quality video renderer (GPU assisted)

[SamuriHL]

I do it all the time. 1080i, 720p....both upscale nicely to 4k. I want to go a little more nuts with my settings for 720p which is why I'm excited for the new cards, but, you can get very good results for both on pretty much any modern card if you play around with the settings. Set up profiles for sure if you're going to do that.

[CZ Eddie]

Where can I find a collection of MKV clips or something for various torture testing so I can eek out MadVR performance?
Like, a video for testing motion blur that is 480p, 720p, 1080p and 4k.
Or another video for testing background noise.
And other for testing detail.
Etc.

Anyone?

I could seriously use a 1080i/60 demo MKV right now.
The only 1080i/60 material I can find is live TV and it's not doing what I want it to do.

[CZ Eddie]

This is how 1080i live TV is showing up.
And it's using my 1080P profile as a result.
I can't figure out how to make it use my 1080i profile.

else if (srcInterlaced) and ((srcHeight > 720) and (srcHeight <= 1080)) "1080i60"
else if (srcInterlaced) and ((srcWidth > 1280) and (srcWidth <= 1920)) "1080i60"

"Deinterlacing on (says source)"
Ignore my frames, I have not tweaked upscale algorithms yet.

a file is 60i or not so it it is a different "mkv" doesn't change that.

why would you even need a i profile madVR doesn't really care is a file is P or i to does mostly the same processing.

and is the 1080p condition true and checked before?

[mclingo]

@mclingo - I'm running RGB.

can you post your controlJ screen running that clip so i can compare, ta

[oldpainlesskodi]

Sure, here you go: https://ibb.co/xfNd4jN

Like i said, i have reverted back to madVR09209.zip, but it's the same with the latest beta build.

And just for completeness, here it is using 113 beta : https://ibb.co/wyprDCG

[mclingo]

cheers, cant see anything of note, cant work this out at all, it works if I force FPS to 23,976 or leave it at 23fps but set my AMD driver to YBCR 422 suggesting its a bandwidth issue, could be my ageing 2015 OLED, its had an issue before your also didnt have which was solved by a recent driver though.

I'm not really too fussed about this but i'd still like to know whats causing this I guess.


edit... it does seem to be MAVR though as windows player plays it fine all the way up tp 60 hz

[oldpainlesskodi]

No problem.

[CZ Eddie]

why would you even need a i profile madVR doesn't really care is a file is P or i to does mostly the same processing.

Because 1080P MVK files run beautiful on certain MadVR settings but JRiver Media Center live OTA TV 1080i is having massive issues with those settings and keeps locking up. It seems to require very easy/lightweight settings or it will not play properly.

So I want a known-good 1080i MKV file to test with.
Something not created by JRiver.


and is the 1080p condition true and checked before?

I don't understand this question?

[Andy o]

So now that finally proper HDMI 2.1 cards will be here, anyone heard anything about QMS support, either from the cards, or from any software like madVR? Has madshi said anything recently about this topic?

[chros]

That shaved about 5ms off the render time. It doesn't seem to like pausing and resuming though.

I just checked it with dxva2-copyback as well, there's only the usual 10% difference on nvidia 1060 (between d3d11-natvie), otherwise the 2160p@59p is flawless, even with madvr tonemapping.
That means that either Win8 is weird or you have a big issue with your setup.
Try it out just using MPC-HC/BE if you use some frontend.

[CZ Eddie]

1080i sample found here.
It is listed as 1080i 29 instead of 1080i 60. Which is accurate, just not what some people might expect.
https://kodi.wiki/view/Samples

Okay, I think I figured out how to tell between 1080i and 1080p in the CTRL-J info.

The 1080i CTRL+J info says "deinterlacing on" which is taking 29.970 and showing it twice.
While the 1080p info says "deinterlacing off" which is taking 59.940 and showing it once.

The wording was confusing but I think I understand now.
Still not sure how to create profiles for each though. But now I have learned more so learning to create a profile specific to 1080i might be easier to figure out now.

Please don't be unhelpful and tell me it does not matter. I'm getting tired of hearing people tell me not to worry about it, instead of just giving me the answer to my question.
If you don't have an answer then please move on.

https://i.ibb.co/Qjcq4BV/Untitled.jpg

[CZ Eddie]

Here are my profile boolean rules.
The first is 1080P.
The remaining three were different tries to get 1080i to work.
Can someone help me figure out how to change the 1080i rules so that the 1080i in the post above uses the 1080i profile?

1080P BOOLEAN RULE:

else if (deintFps > 25) and ((srcHeight > 720) and (srcHeight <= 1080)) "1080p60"
else if (deintFps > 25) and ((srcWidth > 1280) and (srcWidth <= 1920)) "1080p60"

----------

THREE VARIOUS 1080I TRIES THAT DID NOT WORK:

else if (srcInterlaced) and ((srcHeight > 720) and (srcHeight <= 1080)) "1080i60"
else if (srcInterlaced) and ((srcWidth > 1280) and (srcWidth <= 1920)) "1080i60"
----------
else if (srcInterlaced == true) and ((srcHeight > 720) and (srcHeight <= 1080)) "1080i60"
else if (srcInterlaced == true) and ((srcWidth > 1280) and (srcWidth <= 1920)) "1080i60"
----------
else if (srcInterlaced == false) and ((srcHeight > 720) and (srcHeight <= 1080)) "1080i60"
else if (srcInterlaced == false) and ((srcWidth > 1280) and (srcWidth <= 1920)) "1080i60"

[thighhighs]

Hm.. Try this for "1080i60" and "1080p60" profiles:
if (srcInterlaced) and (srcWidth > 1280) "1080i60"
else if (srcInterlaced) and ((srcWidth <= 1280) and (srcHeight > 720)) "1080i60"
else if (deintfps >31) and (srcWidth > 1280) "1080p60"
else if (deintfps >31) and ((srcWidth <= 1280) and (srcHeight > 720)) "1080p60"
If not work check simple rules:
if (srcInterlaced) "1080i60"
else "1080p60"

[chros]

Just to provide a bit of additional context, NVIDIA SMs before Turing (or was it Pascal?) were already capable of 32 FP32 instructions per clock. Turing just traded this capability for the ability to execute 16xFP32 and 16xInt32 simultaneously.

Ampere is just restoring the old functionality (because I guess games don't really use INT32 a lot) while keeping the concurrent INT32 execution. (See page 34 of the Ampere whitepaper. It doesn't seem to mention if it's 32xFP32 and 32xINT32 or 32xFP32 and 16xINT32.)

To try and bring this back to MADVR, does it use ints for stuff or is it all floating-point?

Pretty sure all madvr math internally is FP. It's those rounding errors using INT that cause problems and why madvr is a better solution for rendering.
This is a reoccurring question that I'm not sure about either, along with whether madvr does 16bit or 32bit processing.
From the features section of the 1st post:
- full 16bit processing queue
- final 16bit processing result is dithered down to RGB output bitdepth

@nevcairiel, don't you know the answers for this by any chance once and for all? :)

60i and 60p is the "same" workload for madVR. the difference is that madVR gets a "30p"(60i is practically 30p) signal which first get's deinterlaced to 60p at that point is doing the same thing and deint is not really done by shader so it doesn't add a lot if any overhead.

else if (deintFps > 25) and ((srcHeight > 720) and (srcHeight <= 1080)) "1080p60"

else if (srcInterlaced) and ((srcWidth > 1280) and (srcWidth <= 1920)) "1080i60"

if you use that 1080i60 will never trigger because 1080p60 is true.
you could fix this by checking if the content is interlaced.

I appreciate the feedback but I didn't really understand this, sorry.
I'm slowly learning though.

[CZ Eddie]

So this is driving me nuts.
I was able to separate 1080i60 from 1080p60 and start troubleshooting an issue with live OTA HD programming on JRiver Media Center.
Why? Because JRiver kept crashing when using my custom settings for 1080p60.

But even with lightweight settings for 1080i60 profile, such as Lanczos 3 taps for image & chroma, JRiver still keeps crapping out.
Anyone else have this issue with JRMC?
It will start playing, then it'll start locking up. Maybe continue playing audio while video has halted/frozen.
This only happens with OTA.
If I record OTA and play it back later, then JRMC does better. Much fewer lockups.

I tried asking for help at the JRMC forums but they referred me to the Doom9 MadVR thread for help.

[chros]

I was using just MPC-HC, not a frontend.
What's the spec of you system? (including everything)

[jkauff]

I tried asking for help at the JRMC forums but they referred me to the Doom9 MadVR thread for help.
I'm guessing the problem is that JRMC runs its own version of madVR, which is located in c:\Users\[username]\AppData\Roaming\J River\Media Center 26\Plugins\madVR\. Are you creating your settings there, or in an external installation of madVR? If the latter, JRMC isn't picking up your scripts.

You can copy your external madVR files into the JRMC folder, overwriting all of the files, and JRMC will use your settings.

Are you sure about that?
I mean, yes there is a MadVR at the JRiver file path in addition to the original MadVR I have in the root of my C:\ drive.

But as a test, I played a video in JRiver and edited the MadVR config so my display device was named "JRiver".
Then I closed it all and played a file using MPC-BE and the MadVR it uses came up with the name "JRiver".
So both appear to use the same MadVR?

[jkauff]

Which location did you use to install the .ax file? Both JRMC and MPC-BE will use the location where the .ax file was installed.

I'm completely ignorant of what settings get stored where, but my c:\madVR settings.bin file is always different from the one in JRMC.

You could run a test. Rename the JRMC settings.bin file to something else (so you can recover it later) and copy your c:\madVR settings.bin file to the JRMC folder.

[Bryanhoop]

Or even easier, just use a custom external filter in MC for madVR. You can also right click any playing movie and edit the madVR settings for the instance that is running.

[el Filou]

But even with lightweight settings for 1080i60 profile, [...] JRiver still keeps crapping out. [...] It will start playing, then it'll start locking up. Maybe continue playing audio while video has halted/frozen. This only happens with OTA.
If I record OTA and play it back later, then JRMC does better. Much fewer lockups.And the TV recordings play without any issues in MPC-HC using exactly the same settings?
If yes, try changing the decoder queue setting in madVR, maybe making it bigger or smaller, maybe it's a buffering issue.
Does JRiver have a setting for how much to buffer TS before playback (this introduces a delay to Live TV, but sometimes can fix problems)?
Are you using DXVA2 native or copyback? If copyback, try native to see if it works better. I see the deinterlacing time in one of your MPC screenshots is 31 ms which is unbelievably high and not normal.
Could you please post a screenshot of the OSD during playback in JRiver, not in pause mode (which your MPC screenshots were).So now that finally proper HDMI 2.1 cards will be here, anyone heard anything about QMS support, either from the cards, or from any software like madVR? Has madshi said anything recently about this topic?Oh yes, I want that feature so much too, it would solve all the problems of refresh rate mode changes, not only delay and black screens but also audio cutting and HDMI chain resetting, and it would work for "fixed-timing" apps like madVR whereas using standard VRR for video was too complicated to use as madshi explained.
The thing is QMS uses VRR as the underlying mechanism to achieve its goals, so:
- You need a source and repeater/sink that support VRR so they can also support QMS. (do any review sites already test QMS support?)
- VRR mode must be enabled in the OS and driver
- I don't know if application support for QMS can be handled by the current display mode change functions of the OS, or if would need another API function.

Many conditions that have to be met for this to work.

[chros]

As VBB said, take a look at the Lav screenshot (https://www.avsforum.com/threads/guide-building-a-4k-htpc-for-madvr.2364113/page-142#post-58165252) here. I can update that post during the weekend with my current settings if you like.
I've updated my old madvr config (https://www.avsforum.com/threads/improving-madvr-hdr-to-sdr-mapping-for-projector.2954506/post-59228954) posts, if somebody is interested. Enjoy!

.

Yeah, when I made changes to the MadVR in C:/MadVR, it also changed the settings in the JRiver user path for MadVR.
Or at least I think it did. Maybe JRiver was smart enough to be using the original MadVR in C:/madvr instead of its own MadVR in the username path.
It's all confusing now.
I shotgunned troubleshooting by just formatting and reinstalling OS and just installing JRiver.
Then I restored my troublesome MadVR settings to JRRiver's MadVR and live TV worked pretty good with them finally.

I haven't done much troubleshooting since because as good as JRiver is, I am way more comfortable using MPC-BE as a video player and I think I will go that direction and just leave JRiver for live TV + music play.

[CZ Eddie]

Folks, I currently have a Quadro 2000 full height GPU via PCIe hardware passthrough to my ESXi 6.7 Windows VM.
This GPU was free for me and was used just to ensure that my Win7 Windows Media Center VM could playback its recorded TV from live OTA and CableCard programming.

I now want to build a MadVR VM for Live TV + Live Streaming upscaling to 1080P.
Does anyone know of a MadVR compatible graphics card that would work for low-midrange video settings?
I'll be mostly interested in clearing up the picture defects.

I had a heck of a hard time finding a GPU that was compatible with PCIe hardware passthrough in ESXi 6.7.
Most cards I tried did not work!
So just naming off your favorite budget graphics card for MadVR won't be helpful.
Please don't suggest anything unless you know for sure it's ESXi PCIE passthrough compatible and has HDMI output. :)

[CZ Eddie]

Oh hey, Wikipedia actually tells me which GTX models are similar to Quadro models.
https://en.wikipedia.org/wiki/Quadro

It says the Quadro P2000 (not what I mentioned above) is very similar to GTX 1060.
I think this list will be a big help because Quadro cards are more likely to be supported for ESXi 6.7 passthrough.

It says my current Quadro 2000 (non-P) is similar to a GeForce GTS 450. lol

I actually found this about the 450, posted four years ago:

I'd consider an overclocked GTS 450 the minimum GPU required to run madVR. I am currently using this card at the moment with the core clock boosted to 925 Mhz and the memory clock boosted to 1900 Mhz with MSI Afterburner. This is considered a light overclock, but the card likely can't handle much more.

These are the settings I'm able to use: http://forum.kodi.tv/showthread.php?tid=259188&pid=2238974#pid2238974.

I have to reduce chroma upscaling to Catmull-Rom for 25-29.97 fps content with a couple of the trade quality for performance boxes checked. Those are the only compromises required with the settings posted.

[SamuriHL]

This is the tricky part. The settings get stored in the registry as well as a settings.bin. And that's all good. HOWEVER, unless you go in and actually TELL Jriver to use the currently installed (i.e. the one you've run the install.bat on) version of madvr, it will always use the private copy. Now, you may think, ok so? If they're sharing the settings in the registry, I'm good to go....right? Well, maybe. :) That all depends on if your C:\madvr version matches the private copy that JRiver installs. And I can tell you that if you're using any of the betas, it won't be. Personally I overwrite the JRiver private copy with the beta files and run the install.bat in that directory so that there's only ONE copy of madvr on my system, both registered and used as the private JRiver copy.

What a great idea!:thanks:

[el Filou]

I think this list will be a big help because Quadro cards are more likely to be supported for ESXi 6.7 passthrough.I don't have first-hand experience, but from I've read over the years in the virtualisation community, it's another feature NVIDIA uses to segment its portfolio, and GeForce cards are pretty useless if you want advanced features. Many people hope this will change with the 3000 series, but there's no way to be sure except testing.

Question about bitdepth in madVR and in general.

If one has a new TV it's specs most likely say 10 bit panel, but actually most if not all are still just 8 bit and uses FRC because native 10 bit panel looks the same as 8 bit+FRC. So how should we set the bitdepth in Radeon Adneralin and madVR? If the TV is "10 bit" (8bit+frc) should we set the output in PC or some other external device as 10 bit or 8 bit? I mean if "10 bit" TV uses FRC in that end isn't it then pointless to send 10 bit signal into it? Most of the content is 8 bit, UHD does support 10 bit 4:2:0, but if our TV's have 8 bit panels with FRC? I've never really understood how the bitdepth should be set.

[Pastol]

Hi.

What is the alternative to madvr on the latest nvidia drivers for hdr material on mpc be/hc?

[huhn]

there is none.
if you want HDR output it's madVR.
the next nvidia driver should make madVR work again it is most likely coming tomorrow.

[chros]

In theory, it's better to send 10 bit signal in this case as well.
But a lot depends on the actual models, e.g. LG Oleds are pretty bad with full RGB 10/12 bit signals in PC mode (especially with HDR10). So at the end you have to test your display for defects when using a given signal.

[SamuriHL]

Envy extreme has chosen the 3080 as the replacement for 2080s to provide hdmi 2.1 support. I really hope I can grab a 3080 tomorrow.

HI, my first gen 4k HDR OLED is only about 400-450 nits, i'm going to have this for a while so i'm having a look again at how to get the most out of it. Usung beta 113, I'm finding that tone mapping to SDR looks better to my eye than sending HDR data to my TV, regardless of what values I choose, does tone map to SDR still leave the full extended colour range and gamut untouched or does it drop this to SDR too?

Note, when I say SDR is better, in HDR the skin tones are all wrong, they are sort of grey and under saturated.

These are my current settings, any recommendations for my Ageing OLED?

https://1drv.ms/u/s!AgvFafeelEBilI5a4iySXRKJbfxUCA?e=mX7OsF

i'd log on the other thread but there are a lot of grumpy people on there who dont like answering questions like this.

[huhn]

if you set your device to gamut bt 2020/DCI P3 and madVR to output bt2020/DCI P3 then the gamut shouldn't be any different from sending HDR.

[Alexkral]

These are my current settings, any recommendations for my Ageing OLED?

My LG has the same peak nits and I also prefer tone mapping to SDR. What I find wrong in your settings is the real display peak nits, setting it to a higher value will give you a darker image than it should be, this shouldn't be done except in rare cases. In theory it should be the same, but in most cases there is nothing wrong with reducing it to even 100 to get a brighter image. This is especially true for HDR10 content.

I can't help you with the other settings because I don't use them.

Take a look at the link in my signature, all you have to do is to modify the real display nits from 700 to e. g. 450.
There's a huge difference here between HDR10 and SDR output where HDR10 easily wins, e.g. the image is way more sharper due to the increased contrast.
No color issues here, maybe amd driver is the cause? (I use nvidia here)
Good luck, ask anything if it's not amd related :)

@SamuriHL: good luck to you as well :)

[mclingo]

thanks all, got a few things to look at now, much appreciated.

[mclingo]

no luck i'm afraid, tone map to SDR still looks loads better, more contrast and better skin tones, looks nearly as bad if I send HDR to my TV so I think this is just a bad HDR TV full stop, it was LG's first attempt at 4k HDR as it hasnt had any update for years so i'm probably better off just remaing with SDR, my TV is uncalibrated too so HDR profile could be way off and probably is.

[chros]

Hm, sad to hear it. Note that there's no real HDR calibration exists today. Then replace it with the cheapest LG you can afford, it's truly amazing experience. Take a look at one of your friends place at first though :)

[mclingo]

from my cold deads hands ill let this go tbh, oled 3d is stupid good on this, given the choice i'd still buy this over a c10 :)

[Nikolausr]

I don't know what manners are for asking a question in a 3000 post thread, the answers may be in there already if I dig enough, but it would probably be easier to just ask now.

Is madvr open source? If not, is there any documentation about what is going on under the hood for some of these image quality options? Some of them seem to work very well, and I'd like to transcode bad sources with several of these options even if I can't process it in real time.

Are they just avisyth plugins? Any documentation you can provide would be helpful.

[Alexkral]

There's a huge difference here between HDR10 and SDR output where HDR10 easily wins, e.g. the image is way more sharper due to the increased contrast.

The HDR mode on your TV is quite a bit brighter than the SDR mode, so that's normal. In mine they are quite similar.

Same here. Now I'm reencoding some of my BD3Ds after upscaling them to UHD with my app (I'm using FRIMSource to decode them to 1920x2160 OU and then I just need to double the width with VDSR), and the image quality is much better than direct BD playback.

In theory, it's better to send 10 bit signal in this case as well.
But a lot depends on the actual models, e.g. LG Oleds are pretty bad with full RGB 10/12 bit signals in PC mode (especially with HDR10). So at the end you have to test your display for defects when using a given signal.

Yeah I guess you are right.

I saw somewhere that all the Samsung 2020 models are still 8-bit + FRC so I assumed it's the same with Sony but it seems that this has a native 10-bit panel after all.

Anyway after some testing on this TV I can't seem to see any difference on Sony 10bit HDR demos when I send it as 8bit or 10bit from HTPC, with my eyes atleast.
