madVR - high quality video renderer (GPU assisted)

[cork_OS]

If you add "hdr=on" or "transfer=hdr" to the file name you'll get passthrough even using ffdshow. :D

I confirm it. I'm watching 4K HDR movies using MPC-HC+SVP+madVR thanks to this trick.
It would be better if madshi will add a hotkey to force HDR mode passthrough though.

[mclingo]

Yes it is clear. But how then to change the bitdepth of the output of the madVR depending on the HDR? This is necessary for owners of AMD video cards, as their API does not support HDR with 8 bits.

where would you come accross an 8bit HDR movie though?

[DMU]

maybe he will update the AGS which has been updated according to "user" feat back so it may support 8 bit finally.
This is sad. Now there is already the ability to dynamically control the Windows HDR switch using DXGI. So, there is no particular need for the use of the HDR private API's.

where would you come accross an 8bit HDR movie though?
8 bit output needed for SDR content. But profiles for switching between HDR and SDR do not work. I gave the link above (http://bugs.madshi.net/view.php?id=611).

[huhn]

where did you come accross a 10 bit RGB source?

i'm probably just misunderstanding what you are saying. Are you saying that MADVR is failing to recognise and switch to a HDR profile based on bit rate on AMD cards due to an API issue with HDR?

I tried creating a HDR profile ages ago and couldnt not get it work but I decided I didnt need it anyway so I havent looked at it again until now. I'm looking at it again now as I'm trying to get my processing below 30ms with tone mapping and using NGU AA on my RX580.

i'm pretty close now with these settings, can anyone recommend any other tweaks to give me a few exta miliseconds?

[huhn]

the card it self has nothing to do with this it's the bad API from AMD that is related but the bug is in madVR. and the bug is that the properties are ignored in profiles when "HDR" is used for a check but work if bitdepth are used for the check.

if AMD would work with 8 bit he wouldn't need an profile because he would just use 8 bit (which was been proven to be better for consumer TVs over and over again) but that's not possible because the API is super limited.

all this doesn't change that there is a bug in madVR.

[Alucard777]

At some stage madshi was looking to add support for this but it will either happen in 5-10 years or not at all. I asked pinterf about 10bit parsing/support in ffdshow but he's too busy for this. Honestly I hold no hope of this ever being done in the 2020s if at all.

thank you for your replay & hopefully madshi will add it asap

question about HDR tone mapping, for monitor without HDR support, but with DCI-P3

I bought a 32" monitor and found out they just rolled out a newer model (like under same price lol), both no HDR supported, meaning 300cd/m2 max, but the newer added DCI-P3 gamut, they are basically the same panel but the later one has the DCI-P3 option (92%) besdies sRGB etc.

my question: the monitor I bought which is the older one, no DCI-P3 menu

when we enable the tone mapping, what if a monitor that can enable DCI-P3 in the menu (in monitor's own menu), will it get better result, than the old one, bascially the same panel?

[DMU]

the bug is that the properties are ignored in profiles when "HDR" is used for a check but work if bitdepth are used for the check.

Exactly! Thanks for explaining my bad English.
By the way, this bug allows you to set the bitdepth of dithering other than the bitdepth of the madVR output. For example, you can do 8-bit dithering, but transfer the necessary 10 bit stream to AMD API (AGS) for the correct output of HDR, if I'm not mistaken. The statistics window show this.

My SDR 32" monitor might reach 95% DCI-P3 after calibration, and does not have any menu settings.
So I guest you can try to change madVR settings for DCI-P3 in calibration tab to see if it can get some color enhancement.

[Magik Mark]

Can someone share the best way to watch HDR via madvr in LG C9?

What is the optimum setting?

Any solution on too bright subtitle using xysubfilter and asssubfilter? How do we dim this?

There's a reason "best" kind of posts are not generally considered useful. The settings for HDR are subjective. HDR in madvr is a rather complicated topic right now because the last official release is well over a year old now and doesn't have any of the enhancements to HDR that's been done in the test builds since that time. And those changes are nothing short of remarkable. There's a lot to set up and configure because they are test builds that are designed to test various parameters of the new Histogram Tone Mapping algorithm. People have posted screen shots of their various settings for different display types in the madvr test build thread on AVS. Find one that matches your C9 and start there. But this is not a "flip a couple switches and you get the absolute best quality" kind of thing right now. It'll get there, but, everything is in flux with the test builds.

[tyguy]

I have i7 7700k and a geforce 2070 super using the latest game ready drivers and the playback isn't smooth on my lg c9 in madvr despite the low rendering times. I'm using full screen exclusive and I keep vsync activated globally in the nvidia control panel. Is anybody else having issues with rtx cards with the latest game ready drivers?

[Klaus1189]

There was already an issue with LG C9, but not about "smoothness", but about wrong blacks, see also here:
AMD, Intel and Nvidia driver issues and last recommended version (https://forum.doom9.org/showthread.php?t=176013)
click link for more info in line of 441.20.

But there was/is also a stutter issue with RTX cards, for the workaround see the second Note before Nvidia driver history. Hope it helps ;)

Yeah, they fixed the black issues on the latest game ready drivers. I'll try out those settings in nvidia inspector when I get home and report back. thanks!

Someone else suggested using dx 11 native instead of nvenc, which doesn't make much sense to me.

"Set your video decoder to D3D11 Native (Automatic)."

[huhn]

cuvid is not in an optimal state it currently has no real advantages over dxva2 copyback but disadvantages.
nev had some ideas with it that would be really cool but that doesn't mean he will do it.

Okay, ill go back to using dxva2 copyback I was using that with amd, I thought I was suppose to use cuvid with nvidia cards.

[huhn]

What ideas?

kinda like a d3d11 native with cuvid it's been a while and i don't known if he tested it if he still thinks it maybe worth it but that would be the best decoder available with just one major issue.

it's not worth it if i talk about it.

What are the minimum GPUs required from both Nvidia and AMD that can do NGU image upscaling from 1080p to 4K?

[tyguy]

The suggestions helped for smoother playback and even lowered my render time a bit. I still get 1 repeated frame every 8 minutes or so, but I’m getting no dropped frames.

Is repeated frames something we just have to deal with or are we suppose to get 0 repeated and dropped frames for an entire film?

[mclingo]

most if not all 4k HEVC GPUs can do this, it depends on lots of factors, too many to mention. If you want to throw default MADVR settings at a full bluray 1080p remux with NGU AA every card will play the movie but some will run hot and loud.

If you are on a budget i'd reocmmend a used GTX 1060 or a RX580/590.

The GTX 1060 is a better performer in NGU so if you are not playing 3D MVC movies this is probably the better choice.

The new AMD 5700 or XT is the best current choice for AMD users who need 3D but if you are on a budget look for a used RX580, this is what I am used, I can use NGU AA at medium and also do a bit of tone mapping keeping rendering time around 30ms, however I more than often run it at LOW to keep the noise down as my card can be quite loud,

Like gaming, the more you spend the better the card will be, just throw as much as you can at the GPU and then tweak it to get the most out of it.

[ryrynz]

This is normal and not the result of render times. Either you use Smooth Motion or you match the refresh rate of your display as close as possible to your source content using madVR's 'custom modes' menu within 'display modes' under 'devices'

[oldpainlesskodi]

Have to say, looking forward to the next public/official release - Neo-XP's latest curve over at AVS is quite phenomenal.

Isn’t this something variable refresh rate should be able to fix? I’m using a c9 with a GeForce 2070 super, and I have variable refresh rate working through “gsync compatibility.”

Of course my card can only do 60 hz at 4K since no hdmi 2.2 output, but shouldn’t this fix it when we have hdmi 2.1 cards?

[huhn]

madVR doesn't support it(it''s complicated for video).
the VRR ranges is another problem. at a resolution with 120 hz support it should be fine but at UHD 60 is utterly useless because it can't do LFC making it very hard to get a video into the VRR range.

Yeah, the range on my tv is 40-120 hz. Xbox will do lfc at 20-30 fps because that doubles from 40-60 hz.

I dont think nvidia will do that though so I would have to drop to 1440p if I wanted full range (atleast until hdmi 2.1 graphic cards come out).

You would think using dx11 native would just engage variable refresh rate.

This seems like the ultimate solution to the repeated frames problem. This guide I read said your card can only output 8 bit in madvr if you use custom modes... Which seems far from optimal.

[huhn]

Yeah, the range on my tv is 40-120 hz. Xbox will do lfc at 20-30 fps because that doubles from 40-60 hz.
the xbox can't do 120 hz uhd it does it at 1440p or 1080p and then this feature will work.

You would think using dx11 native would just engage variable refresh rate.
it's not that easy in my experience it is blocked and it's planned to be blocked for fixed FPS games too a video is part of this category too. this doesn't make sense to me 144 hz is very common and 60 fps at 144 is just bad but totally fine with g-sync.

and g-sync for video is very complicated it's not a game where A/V sync doesn't exist. audio that "need" sync in games is usually only a couple of secs so it doesn't matter and the sync of BGM is irrelevant. but for movie playback you have to sync an video to an hour or longer audio stream it not build for that.

to properly use that madVR needs to measure the difference between audio and video clock fix this using the system clock. yeah lot of fun.

you mean better for lg oleds.I read somewhere if you set your xbox to 4k 60 it will still do LFC on 30 fps titles that dip below 30 fps since 25-30 doubles into samsungs vrr range. Well, im assuming the 2020 and beyond lineup of tvs will start to feature hdmi 2.1 from every manufacturer. So it wont just benefit lg oled.

Why? On LG's OLEDs 8 bit has less banding than 10 bit when in PC or Game mode. 8 bit is more optimal than 10 bit.

I still think VRR support in madVR would be useful. Playback wouldn't be as good as a tuned fixed refresh rate but we wouldn't need to worry about refresh rates at all. madshi is less interested simply because it is going to be worse. I think the minor judder from imperfect presentation timing would be fine, way better than 23fps at 60 Hz, and audio sync is pretty easy if having all frames presented for the exact same amount of time is not considered too important. Simply adjust the frame times a tiny bit as you go to maintain sync.

madVR is all about quality so spending a bunch of work to get VRR support for gaming monitors to support a slightly worse playback mode was not reasonable. However, now that TVs are getting VRR too it might be more reasonable to look into it? Probably not. :o

[huhn]

the problem is someone has to write the code for this and how do you even say the GPU this frame 0.5 ms later plz?

want to handle everything with chrono?

[tyguy]

I'm only using 8 bit color depth in madvr because im using rgb full 8 bit in my nvidia drivers and nvidia wont switch to 10/12 bit when it drops the refresh rate.

I dont label my hdmi input anything. I just keep it to default hdmi 1. With 8 bit I haven't noticed any banding. I will be getting a new card when 2.1 cards come out though. So ill be running my desktop at 4k 120 hz rgb full 10/12 bit.

Would there be an issues if I set madvr to 8 bit, but im using 10 or 12 bit with my nvidia drivers?

[Asmodian]

I dont label my hdmi input anything. I just keep it to default hdmi 1. With 8 bit I haven't noticed any banding.

Using the default HDMI input the TV will convert to YCbCr 4:2:2 internally. This blurs the color information horizontally. Both color planes are resampled to 1920x2160 by the TV. This does eliminate banding with 8 or 10 bit RGB input but the image is blurred. I hope you are using very low power chroma scaling options because anything better is pointless.

Would there be an issues if I set madvr to 8 bit, but im using 10 or 12 bit with my nvidia drivers?

No issues except being totally pointless, why set Nvidia drivers to anything but 8 bit? There is absolutely zero improvement in quality on an LG 7/8/9 when sending it 10 bit instead of 8 bit when using any HDMI option, and 10 bit is worse quality when using PC or Game mode.

Ideally you want to send an LG C9 8 bit YCbCr limited range using the PC or game HDMI mode. Anything else either has banding or blurs the chroma. If you set the drivers to YCbCr limited set madVr to full range output.

I know 10 bit sounds cool but it really is pointless at best on an LG OLED. I will be using 8 bit YCbCr limited range 3840x2160 @ 120 Hz on my LG C9 when I get an HDMI 2.1 GPU unless I get a new TV that is not so bad with RGB full input. :mad:

[YukonTrooper]

My aspect ratio for HDR files is broken using MadVR in any player. The film area is off-center and stretched. Playback without MadVR OK. Any ideas?

you could start with a screen of the OSD (control+j).

Where did you get the information about the tv internally doing Ycbcr 422? I thought in Windows you always want to use rgb because windows will just convert ycbcr to rgb?

Also, why is my Apple TV able to do 10 bit without banding, but my windows pc can only send it 8 bit dithered or else I get banding?

Finally, why would I set madvr to full if I’m using limited and have my TV set to low hdmi black level?

I’ve seen a lot of conflicting information out there. It’s hard to know what to believe.

[Asmodian]

Where did you get the information about the tv internally doing Ycbcr 422? I thought in Windows you always want to use rgb because windows will just convert ycbcr to rgb?

It is easy to test for yourself. With ChromaRes.png (https://www.mediafire.com/view/40a9jrk3q03s7gk/ChromaRes.png/file) you can test which modes use 4:2:2 or 4:4:4. View this image at 100% scaling, i.e. in a window on a 4K screen, and switch between hdmi and pc modes. With the gradient test patterns I linked above you can verify all of what I have said. :)

Windows will always render in 8 bit RGB but if you set the GPU to YCbCr it converts everything to YCbCr. madVR always outputs RGB too.

Also, why is my Apple TV able to do 10 bit without banding, but my windows pc can only send it 8 bit dithered or else I get banding?

Because you have your HDMI port in the default mode, also the Apple TV is sending subsampled limited range YCbCr so this isn't really a problem. However, madVR with 8 bit output and the GPU converting to 8 bit YCbCr 4:4:4 is higher quality.

Finally, why would I set madvr to full if I’m using limited and have my TV set to low hdmi black level?

Because limited in the GPU drivers means "convert the full range RGB into limited YCbCr." If you set madVR to limited range too you get double limited because the GPU always converts, it has no way to know madVR is sending limited range.

The reason madVR has a setting for limited range is because if you only care about madVR and don't mind if everything else in Windows is wrong you can set madVR to limited and the GPU to full range. This results in the same image but without the GPU converting ranges. I care about everything else too, and the drivers still need to convert the RGB to YCbCr anyway, so I use limited range in the GPU and full in madVR.

Also, what is ideal in principle and what is ideal in real life with an LG 2019 OLED is not the same thing. :(

I actually don’t have my Apple set in default mode. It’s hooked into my receiver which I have labeled “home theatre” in the input section. Maybe that’s the same as default hdmi, but I can always just label that game console or pc as well and see if I can notice banding.

I don’t think you can get wide color gamut from a console or Apple TV without sending the tv 10 bit because they don’t do dithering.

If Windows is converting ycbcr to rgb and madvr only outputs rgb....Why not just use rgb 8 bit limited instead of ycbcr 422?

[el Filou]

Because the LG's processing of RGB input is of lower quality.

hi, this issue with LG OLEDS, its quite confusing,, there is a lot to take on here and some conflicting information to what ive been given in the past. Firstl, does it extend to older models, i have gen 1.0 EF950v, i've never noticed any banding to be honest, my current setup is as follows:

HDMI 1 selected, lleft it named HDMI 1
Expert 1 profile set to HIGH colour space
AMD RX 580 running at 4:4:4 FULL RGB set to 8 bit in graphica settings
MADVR set to 0-255

everything looks fine to me, however I do have an issue if I use the actual "PC" HDMI input setting, SDR is fine but no matter what I do HDR is massively washed out and gamma is all messed up, nothing i do corrects this, I dont use PC mode anyway though as I use a tiny bit of smooth motion which greatly improves bright panning shots without any artefact or soap opera effects.

Are you suggesting I should be runniing my panel in PC mode and at YBCR limted mode, what should I actually see on that chroma res pattern, I see 442 clearly but I can also see 444 albeit fiently.

I dont see any banding in either of those movies, gradients and pretty smooth.

[Stef2]

I would like to hear from madvr users with a projector and an anamorphic lens.

I just bought such a lens and when I enable the anamorphic option in madvr (4/3 vertical stretch in my case) the rendering time goes up quite a lot, increasing from 36ms average to 55+ms average after the stretch...

Of course, that makes my 4K HDR 24p movie unwatchable :(

The only way I gan get the rendering time back to below 40ms is by disabling completely any HDR processing in madvr, but that deteriorates the projected image a lot, of course. Decreasing luma and chroma upsampling quality by a lot is not enough. Decreasing dithering quality is not enough. Enabling every "trade quality for performance" option over all that that is not enough...

My GPU is a GTX 1070. I do not mind upgrading it to a RTX 2080 if this is what I will need.

Is there any anamorphic lens user around here? what do you observe when enabling this option? Any RTX 2080 user can help me by observing the difference in rendering time between no stretch and anamorphic stretch enabled in madvr.

Any input is welcome!
Thank you.

[Asmodian]

I actually don’t have my Apple set in default mode. It’s hooked into my receiver which I have labeled “home theatre” in the input section.

Yes, Home Theatre is the same as the default, it subsamples the chroma.

If Windows is converting ycbcr to rgb and madvr only outputs rgb....Why not just use rgb 8 bit limited instead of ycbcr 422?

Windows is not converting YCbCr to RGB. :confused:

The GPU driver is converting the RGB from both Windows and madVR to YCbCr. Do NOT use YCbCr 422! That would be subsampling the chroma in the GPU driver instead of the TV. :p

If you are asking why the TV uses YCbCr 422 internally it is because TV manufactures are too cheap to get decent video processing chips. YCbCr 422 only takes 2/3 of the bandwidth of YCbCr 444 so they do not need as capable of hardware.

In the Nvidia drivers I cannot set limited range RGB anymore so I did not test limited range RGB (that isn't really a standard either). Better to use YCbCr as always limited and RGB as always full range. The TV is expecting YCbCr limited range input because that is what Apple TV, bluray players, etc. will send it. LG got it working reasonably well for that but they seem to not care about the quality of full range RGB input.

@Asmodian
And the output at 60Hz@RGB@PCMode does not solve the issue's on LG OLED?

The refresh rate does not change the banding with RGB input in PC/Game mode in anyway but it does solve the issue with judder with any non-60Hz input while in PC mode. I always use 60 Hz with smooth motion now. Once in PC mode (so we get full resolution color) these TVs are pretty finicky and only seem to handle 8 bit YCbCr 444 limited range 60 Hz input well. :(

[Asmodian]

the problem is someone has to write the code for this and how do you even say the GPU this frame 0.5 ms later plz?


Yes, of course it is work for madshi that does not improve the quality in any ideal scenarios. This is the best reason for it not to exist.

But it isn't that hard to decide what to do (coding it is another issue), simply wait 0.5 ms and then present the frame. I probably cannot tell if a frame is 0.5 ms early or late anyway and the even smaller inaccuracies due to Windows scheduling are even less important. As long as the player is presenting the frames close to when it should audio sync is a non-issue. If this would be better than smooth motion at 60 Hz I don't know, I am pretty happy with smooth motion already so I am not sure it is worth the effort. However, as it is now I need to manually turn off VRR when I switch from gaming to watching video. :p

HDMI 1 selected, lleft it named HDMI 1

Nothing I said applies if you let the TV subsample chroma (e.g. do not use the PC HDMI setting).

Also, use the banding test patterns to judge banding. I do not see obvious banding with normal content except very rarely. I also don't know about models that old, I have only tested the C7 and C9 myself.

HDR tone mapping is obviously worse quality on my display when in PC/Game mode, I really wish LG did not subsample chroma in their video processor. According to my calibration software the gamut is much smaller, which results in less saturated/washed out video but the gamma is still reasonable, not as good, but reasonable. I do switch to Home Theater when watching HDR (rare for me).

The refresh rate does not change the banding with RGB input in PC/Game mode in anyway
On my Samsung I notice only 1 issue in PC mode: if the frequency of the HDMI input is not 29/30/59/60Hz, then the TV switches to 422 mode.
