madVR - high quality video renderer (GPU assisted)

[Sunset1982]

It was not due to the Windows 1803 update. It was due to the Nvidia drivers returning poor quality when using HDR + Windowed 10 bit at the same time, so madshi disabled Windowed 10 bit as a quick and dirty "fix".

So do the latest divers work?

[Asmodian]

I don't know how the fix worked, perhaps madshi simply changed it to only disable Windowed 10 bit for HDR (where the problem is)? :o

[tony359]

You were right, thanks. It's strange because Focus Assist was supposedly disabled, but problem went away only after unticking all options.

THANK YOU! I had set Focus Assist to OFF but it was still causing issues. I did not realise I had to "untick all the options" as you said!!

Cheers! :thanks:

Hi fellows,

I'm sure I am not the only one following progress over on the AVS forum....waiting patiently.

Can anyone else with a HDR set confirm at this stage that madVRhdrTestFinalColor4.zip is producing a picture with far more depth, contrast, and better tone mapping than the latest version (today)? Maybe I am misunderstanding the latest builds in terms of what it is trying to achieve - are the latest builds purely about trying to restore detail, or is Madshi, using the results of Color test builds, and now on to restore details?

Forgive me if it's a stupid question, but on a HDR set, madVRhdrTestFinalColor4.zip is producing the best image of all test HDR to SDR builds to date (100, 100, 100, 75, 50, 25, off, off)

Hi, you made me try the beta / testing build and is it me or i find the colors to be less good than the official build ??

http://screenshotcomparison.com/comparison/118503

in HDR passthrough , the colors look a lot more like the official build.

[foobar2000]

newer cards, better picture qulity?
folks, there's a question confuses me for years...

well, if my AMD card doesn't support 4k/HEVC/x265 hardware decode, like hd7000, but it did supports 4k output, means you gotta do software decode, which is ok, and it's GCN1 and UVD4

what if
if I buy the latest Vega, vega is CGN5 and UVD7, supports hardware decode (hevc etc), what if compare them both under the same setup to do software decode (dxva turn off), should I get better P Qulity with the more advanced Vega? UVD7 man

https://en.wikipedia.org/wiki/Template:AMD_GPU_features

[Asmodian]

No, how you decode it has no effect on quality.

Yep, madVRhdrTestFinalColor4.zip is similar but slightly tweaked and is ok with the settings I posted, but the latest test builds certainly seem to have lost their punch.

Hello, there's a qay to change color/dim the brightness of external subtitle while playing hdr file?

[foobar2000]

madvr high qulity setting for down and up scaling requires tons of memory of video card ain't it? I press Tab in potplayer showing that my card's memory been eaten up 100%, 24fps drops to 6 (after choosing inferior options makes everything smooth), all in all madvr is a "GPU"-need program, depiste being dxva-off, but still needs tons of GPU power

should upgrade to 4GB card, or even 4GB isn't enough

[Megalith]

Is smooth framerate conversion the most CPU-intensive feature?

CPU-intensives are fine, greatly fine:)

depends on the output resolution it has been over and over repeated to use 4 GB for UHD.
even 1 GB can be fine for FHD and 2 are totally fine as long as you are not changing the queue for what ever reason.

madVR SM doesn't use the CPU.
i guess the most CPU depend feature is either HDR peak brightness measurement or IVTC.

Hello, there's a qay to change color/dim the brightness of external subtitle while playing hdr file?
madshi ask about HDR subtitles in the github of libass and well... he was shutdown hard by one of the mpv developer that clearly doesn't want to have anything todo with HDR. so HDR subtitle handling is currently in a bad spot. so you have to hope that the ISR in MPC-BE will have a fix one day or cyberbeing is saving subtitles yet again.

There's some known issue with ryzen 5 2400g?
I can't get proper hdr on my lg b7 :(

[mclingo]

what do you mean by "proper", explain your problem in detail, also where does the CPU come into this, are you not using GPU decoding?

[foobar2000]

actually my first impression was that madvr almost doesn't use CPU at all, it's so GPU-esque, we gotta go straight to 11GB memory card

[Bl4ze87]

Color are not so "vivid" like when i play the same video trough usb directly on the tv, or using plex.

It is definitely improved. I wouldn't confuse high saturation with HDR. That is not the intent of HDR. The old algorithm was oversaturated and overall hue accuracy is better in the screenshots I've compared against other HDR and SDR references.

Pop in the colors doesn't tell me that it is accurate. New OLEDs like the models from Sony and Panasonic render HDR images with less saturation compared to LG OLEDs because they were tuned by colorists to be color accurate. The most common complaint with the previous tone mapping was that it was too saturated.

[Warner306]

The extra punch with HDR highlights in that build was causing artifacts and a loss of detail, so it was toned down considerably. It was maybe too much image pumping.

[Warner306]

I think it could be an issue with current AMD drivers after the troubleshooting you've done. Does changing the color gamut in calibration change anything? It shouldn't do anything, but some AMD users find changing this setting changes the output of madVR.

Did you confirm in the madVR OSD and through the information on the TV that you are in fact playing an HDR source? Does madVR report the mastering display peak brightness in its stats?

Hi, yes, as Warner states, There is a bug with all drivers drivers since 16.8.1 which overblow the colours in movies when playing SDR content at 23hz, this isnt appearent at 60hz or HDR material or if you , is this what you are fining, is everything red and overblown?

This may only affect RX cards I cant speak for none HDR cards or Vega.

EDIT - i've logged the issue with AMD a few weeks back at the same time I logged an issue with HDR failing to toggel after 18.3.4, the fixed the HDR toggle with the latest driver, hope to see the colour issue fixed at some point.

What i'm not sure about though is whether upgrading to WIN10 1803 will fix that or not, but i'm not going anywhere near that :)

With color gamut you men the color depth in radeon sw or there's an option in madvr?

Sorry english isn't my first language and i can't understand the meaning of the word overblow ^^'
I don't have problem in sdr, only in hdr. Color are normal, there's no red tint or strange dominant, the global iamge is only less vivid, strong, like when i play the same file with the tv internal player.

OK, so your problem is with HDR material, is it all washed out, do you have a HDR TV or are you doing a HDR to SDR conversion in MADVR?

[Bl4ze87]

Exactly!
The odd thing is taht when i go in fse the tv switch to hdr

[mclingo]

so you are getting washed out colours but your TV is definitely switching to HDR mode, are you sure?

Press contrl+J when playing a movie and post a screen shot of your OSD

Hmm. I know most of the audience on AVS are projector owners, so they may have different requirements to people that own high nits/brightness HDR capable TV sets that prefer to let Madvr handle the tone mapping.

I have been and will continue to follow the AVS thread (lurker), but, I may end up keeping madVRhdrTestFinalColor4.zip

What does the TV information say while playing this file? Does it also report HDR?

It looks like an HDR source, although it has an odd mastering peak (1200 nits) and framerate (24 fps).

I assume you tried other files?

Try setting chroma upscaling to something besides DXVA. This is hardware scaling and could be interfering somehow.

You could check if there is anything unusual in the file by downloading MediaInfo and looking at the file contents (right click -> MediaInfo -> Text View). There is a link to the MediaInfo utility at the end of this post (https://forum.kodi.tv/showthread.php?tid=223175&pid=2735833#pid2735833) and a sample to show what a proper HDR source should report. It might be missing MaxCLL and MaxFALL if these values are set to 0,0, but that is not uncommon.

There is a calibration section in madVR. This only applies to SDR content, but you can try setting it to BT.2020 in off chance it fixes the colors. The code is probably unrelated, but I don't know what else would be producing the wrong colors. Improper tone mapping due to incorrect or missing metadata would be the most likely cause.

Try some other content. HDR demo material is often mastered with incorrect metadata.

The tv info also show 2160p HDR.
Yes, i ve tried lot of different file, that image was only the last one i ve used.
Chroma upscaling is NGU for all the profiles.
Mediainfo looks good
Last but not the least, yes i've tried different option in calibration, but always without change.
During all my attempt i ve also changed lot of hdmi cable, used a dp->hdmi, but always the same result

[foobar2000]

madvr's being GPU-heavy is a bit crazy, like gaming but only requires memory

EVR CP usually eats up 50MB max of card's memory while madvr uses 100% and wants more, a lot more, so hungry

[huhn]

with default setting madVR uses about the same if not less than EVR-CP.

actually madVR doesn't really care much about Vram without NGU you are close to 2Gb with to 2-3.7 GB when using UHD.

I did enable the NGU (the famous NGU), no wonder it spends so much vram

[strumf666]

With madVR you at least have options ;)

[zaemon]

Really excited to see the new RTX GPU and evaluate what can be achieved with madVR. With a GTX 1080, I can’t use a better scaler than Jinc for UHD to 4K upscaling.

[ryrynz]

Aye? surely it's your other settings like chroma, postprocessing, quality for perfomance options holding you back here... Someone else with a 1080 comment on this, 60fps content perhaps?

[Zaoshi]

I have GTX 1070. For my 1080p content I use NGU Anti-Alias (high) < Bicubic150 LL AR (my monitor is only 1440p) + Remove Compression Artifacts High. Content is only 24 fps though.

[oldpainlesskodi]

@ zaemon - I have a 1080 oc and have no problems with virtually any scaler for 4k material (with pre and post processing) for 23.976 material.

As ryrynz asked, if its 60fps, you will need to dial back on processing options.

What are your settings? Are you using supersampling?

[ryrynz]

Are you using supersampling?

Can't do that with Jinc, just from whatever UHD res -> 4K.

[oldpainlesskodi]

Can't do that with Jinc, just from whatever UHD res -> 4K.

Ah I see - learnt something new.

[ryrynz]

It's a great upscaler though, if you can pick it (it's expensive performance wise) you really can't go wrong with it, It's my preferred scaler for any extra upscaling. Also it does a damn fine job as part of SSIM2D, but my lord is it expensive.
I only just manage to get away with using it on my 1060 6GB on Full HD content after NGU sharp has doubled it. I think by the time I have a 4K TV I'll have enough GPU power to do it justice.

[oldpainlesskodi]

@ ryrynz - same here

NGU Sharp very high>Jinc when needed.

[Razoola]

Only thing Im intrested in at the moment is what hardware decoding the RTX 2080 / 2080ti will have. Hopefully nvidia have given it totally up to date decoding ability.

[foobar2000]

why high setting downscaling is much less "hard-on-your-gear" than high setting upscaling?

what do you even want to add they can already do pretty much everything...

[nevcairiel]

Indeed, the decoder on the 1050/1050Ti/1080Ti leaves very little to be desired. I don't expect AV1 to be ready quite yet, so it may see performance improvements but what new features would they add to a decoder?

[mi3gai4rui4]

Hi,
Sorry if this is documented somewhere but I couldn't find it. Is HDR auto-switching supported on the latest Intel GPUs with the latest drivers?

[Razoola]

what do you even want to add they can already do pretty much everything...

I'm on a 980 so I would like to make sure they support 10 bit decoding etc.

[nussman]

Off topic ... really dislike this stuff in madVR thread!

[Asmodian]

Is HDR auto-switching supported on the latest Intel GPUs with the latest drivers?

No, madVR only supports the AMD and Nvidia APIs for HDR switching. I am not sure if Intel does not have one or if madVR simply does not support it.

[huhn]

I'm on a 980 so I would like to make sure they support 10 bit decoding etc.

every nvidia card since the 960 release date can do HEVC 10 bit.

so you ask for something that's a given for over 3.5 years.
