madVR - high quality video renderer (GPU assisted)

[mclingo]

I perhaps agree that a general driver issue should really be migrated onto a more general thread, perhaps we can once we've flushed it out a bit more. However this is only affecting MADVR and so should remain here for now I feel, regarless of whether it only affects NAVi cards or not. We've had 90% NVIDIA discussion for months now, I feel you need to let us AMD users have this one.

[nevcairiel]

This is not how anything works. Someone else did something wrong, so we get to do more wrong? No.
This is not a competition between NVIDIA and AMD who gets to spam more stuff into the madVR thread.

If you want to get madshi's attention, you should keep this topic as clean as possible, and discuss your driver/card issues elsewhere, and when you collect all the facts and reach a conclusion, you can summarize it here.
Trust me, he is far more likely to gloss over back-and-forth driver discussion and just stamp it away as a "driver issue", and more likely to actually read a succinct summary post.

[mclingo]

where I tend to agree, its MADVR users that we need to engage and this is where most of them reside, not the general AMD user. As youknow I tried creating a general thread for this very purpose but there just isnt enough people monitoring it, so we're back here.

I dont think MADSHI is engaged with this thread at all at the moment do I dont think it matters at all how or what we discuss, for once though we're actually discussing a problem in MADVR instead of comparing green vs red or OLED vs LCD.

I personaly think this is a valid discussion topic for this thread.

If you say so... I think it's more likely that he will not respond in any way, and I'm on nvidia so this question does not concern me directly.

Hi, that shader does the trick, couple of questions,

what does that tell us about the problem, does this mean its definately an API issue and we can take this straight to AMD and have them fix it, has anyone tried this yet?

If this indeed an API problem I dont understand how one owner of a 5700 can have a problem in MADVR and another doesnt.

[DMU]

has anyone tried this yet?
Yes, I tried (https://forum.doom9.org/showthread.php?p=1877100#post1877100). This shader fixed (https://forum.doom9.org/showthread.php?p=1875170#post1875170) the colors.

[mclingo]

i meant has anyone tried logging a fault to AMD based on this fix in that we appear to know exactly what the problem is now?

Sorry, no idea about that. I only identified the problem and it occurred to me how to solve it. It has been said that it happens because some AMD drivers get confused with the gamut flag placed by madVR, but I don't know. But if this doesn't happen with the EVR, then it's an issue with madVR not with the drivers.

The shader can be automated in terms of the resolution of the video, for example to work only with videos with a height greater than 1080.

drivers support for 5700 started a 19.7.1 so it cant be that unfortunately.

I cant log a fault at the moment I cant get to my GFX serial number as I cant take my card out until the weekend at the earliest.

[mclingo]

i submitted the issue to AMD, if they need any more specific info i'll post here or PM you.

[Morgin187]

hey so im trying to match my tv q9fn with the refresh rate of 23.976 or double it with custom resolution utility. but my tv isnt supported at those resolutions. im trying to find a way on mpc hc but it doesnt change when i set it on options>fullscreen>use autochange fullscreen monitor. is there any way to change it in madvr. im changing it in madvr settings>custom trying to get double the video fps 23.976*2 = 47.952 but it tells me my gpu has rejected this

[mclingo]

yeah, fair enough madjock but no real harm done, its just a forum mate :)

i'll report back though if I hear anything from AMD on this.

[Klaus1189]

... gpu has rejected this

Use the timing details of that resolution-refreshrate combo and create it with CRU and check if the TV supports it.

[Siso]

Speaking of refresh rates, which option is better - to overclock your display with higher refresh rate and leave it to be the default example 72 Hz, or make a lower refresh rate like 48 Hz and set madvr to switch it when the playback starts?

[Morgin187]

sorry but timing details from where (control panel, cru, madvr)? Ive managed to set it at 23.975 in cru it wont do double but laso would there be a better experience trying to work out how to get the output to be double 47.952hz?

[Klaus1189]

from madvr suggested timing details. It depends what you like best, I personally want to keep the filmlook like the filmmaker wanted it to look, so I use straight 23 Hz.

[Morgin187]

yeh ive managed to fix it. got it at 23.975 and it switched automatically when playing videos in madvr. thanks alot its made a huge difference matching the refresh to the source. also going to stop looking for things like this and then spending hours trying to solve them lol. thankyou very much for all your help i appreciate it loads

[Asmodian]

I personally want to keep the filmlook like the filmmaker wanted it to look, so I use straight 23 Hz.

24 or 48 Hz are identical as far as the film look goes. There is no frame rate conversion or anything (assuming smooth motion is off, which is should be with a tuned refresh rate). All that happens is that the frame is displayed twice. This is not perceptible, it really is identical to watching at 23 Hz, so there is no downside to using 48 Hz if your display has trouble with 23 Hz or if you simply want your mouse more responsive when watching 23 fps content.

[Klaus1189]

I know but why hassle if the TV can not display special framerates, the native do work at least. Maybe I was not clearly enough, I personally prefer 23 Hz over smooth motion at high refresh rate because this is not like the filmmaker wanted it to look.

I tried already some time ago twice refresh rates but only a very old Monitor did accept such a refresh rate, every TV I tried didn‘t supported it.

[Siso]

I personally prefer 23 Hz over smooth motion at high refresh rate because this is not like the filmmaker wanted it to look.

What do you mean by smooth motion enabled with high refresh rates? Like 72, 96, 120, 144 Hz + smooth motion?

[ryrynz]

I personally prefer 23 Hz over smooth motion at high refresh rate because this is not like the filmmaker wanted it to look.


You can "personally prefer it" that's fine, I prefer it also but it's because the image is noticeably sharper on my current and previous set.

To say it's "Not as the filmmaker intended" is getting confused with the recommendation of filmmakers for disabling motion interpolation which I agree with as it actually presents the film quite differently from intended.

Smooth Motion actually attempts to display it actually as the filmmaker intended. Most purists would agree with matching refresh rates to source frame rates but for some there is not a noticeable difference between the two.

Also recall the calculations done by Asmodian not that long ago that show that the higher the refresh rate the better Smooth Motion performs with less blended frames.

[mclingo]

Hi, just wondering, why does doubling refresh rate make it look sharper?

[Klaus1189]

On some TVs the picture settings can be adjusted according to refresh rates, at least on all my Samsung TVs and there is also in PC the difference that picture looks natural at 50 (0 ... 100) without any additional sharpening, but on 60 Hz in PC mode it has to be adjusted to 0 that no additional sharpening is done.
And why bother with double refresh rates for no benefit at all, despite that it might not work at all on most TVs because it doesn‘t allow weird refresh rates, at least weird for the TV.
I have a socalled 120 Hz panel and everybody tells me that it is much better, but I do not see any benefit at all compared to a good 60 Hz panel. I also don’t know why they call it that way, because these panels display can display 50 Hz also.

I can live with that that I am a „purist“, but if you have a 50fps video and watch it at 60Hz how can this be smooth especially at panning shots. This is another reason for me to use matching refresh rates.

But hey, everybody how he/she likes.

I mean using higher refresh rates which can not be a multiple for all major refresh rates like 23/24/50/59/60.
I dropped 25/29/30 because you loose the intention of interlacing if you use one of these three.

To come back to 144 Hz for example, how can that display all different framerates right without having changed the smear, I don‘t know if this is the right word, but if you do anything to watch it on another multiple than the native refreshrate matching for that framerate, you will change the picture to be clearer or more smeared. I mean for describing the motion speed, the filmmaker can choose the right settings in the cam. But using matching refresh rates doesn’t affect that sort of thing.

Every better hardware player can do it, but I like a software player best, for best future proof.

I bet that every Blu-ray player above 50 Euro does support 24Hz output when the movie starts. My good old ps3 does that also. I am not using it anymore but it did it already 10 years ago.

[Asmodian]

It isn't doubling the refresh rate that makes it look sharper, it is turning off smooth motion at 60 Hz and using a tuned ~24/48/96/120 etc. Hz refresh rate that is sharper (60Hz without smooth motion would be just as sharp but would have terrible judder). Smooth motion blends frames to present the source frame rate as accurately as possible on the display's refresh rate. It does not smooth the motion beyond avoiding terrible judder but the use of blended frames does reduce apparent sharpness to some degree.

At high refresh rates this becomes minimal and the experiance of a tuned 23Hz and smooth motion at 120+ Hz is effectively identical.

Edit: I don't know what issues your TV has but I am confused by your rant. I don't think anyone has ever suggested 50 fps on 60 Hz. That looks bad no matter what. You really want the refresh rate to be at minimum over double the frame rate before smooth motion is a decent option.

Smooth motion for any normal frame rate on a 144 Hz screen works very very well. Motion blur is still exactly as the movie was shot, there is nothing that changed or should be changed about the motion blur when using smooth motion at any refresh rate. madVR's smooth motion is not like your TV's or whatever motion interpolation. We are talking about how often the electronics update, not how often the image actually changes. :p

I am also not saying matching the refresh rate is not ideal, or that using double the frame rate is better; only that it is not worse.

[Morgin187]

I get ghosting when using smooth motion in madvr. So far matching the exact frame rate to the movie frame rate gives a smooth and film like experience with no judder or artefacts. This coupled with 10 judder and 5 smooth on my tv settings gives a almost perfect picture.

[Asmodian]

This coupled with 10 judder and 5 smooth on my tv settings gives a almost perfect picture.

These seem suspect to me. What do they do and does it actually look better with them on? How does smooth motion look if you turn them off? You definitely cannot mix smooth motion with any of those options. Smooth motion is really intended for monitor like displays, displays that do not do any of their own image processing.

Why not just use a matched refresh rate? That or an exact multiple is always the ideal if you can get it.

Edit: Again, smooth motion is not trying to improve anything beyond a matched refresh rate. Smooth motion is for getting an experiance close to a matched refresh rate (assuming a high refresh rate display) without needing matched refresh rates.

[Klaus1189]

Asmodian, are you referring to me with post #58142 (https://forum.doom9.org/showpost.php?p=1892746&postcount=58142)? If so, I cannot see the connection. What did I wrote and must admit don't understand that. Please use easier words for a non-native english speaker :p

I did several tests in the past and the motion isn't that bad, but for example I get some parts of the image in scenes especially with detailed textures are getting flickering, but on native refresh rate it is fine. I stay where I am and all theoretically stuff cannot beat my own perception of the image, that it looks best to use always the matching refresh rate.

Here's an animation (https://de.wikipedia.org/wiki/Zeilensprungverfahren#/media/Datei:Indian_Head_interlace.gif) how I see the flickering, keep it mind, that it only looks that way, and got nothing to to with interlacing because the videos are progressive.

[Asmodian]

I think you misunderstood my entire point.

Nothing is better than a perfectly matched refresh rate, or a perfect multiple of the frame rate. Keep using your settings! :)

[Klaus1189]

I think you misunderstood my entire point.
That is very possible for me :D

Nothing is better than a perfectly matched refresh rate, or a perfect multiple of the frame rate. Keep using your settings! :)
Good to know ;)

[huhn]

I have a socalled 120 Hz panel and everybody tells me that it is much better, but I do not see any benefit at all compared to a good 60 Hz panel. I also don’t know why they call it that way, because these panels display can display 50 Hz also.

they are called 120 hz panel because they display 24p at 120 hz.
displays don't support refreshrate as 24p not even in cinema where 72 and 96 hz or even more are used to display 24p sources on refresh based technology.

a 60 hz panels usually can't do 24p at all they convert it to 60 using a 3:2 pullup which is clearly not the creators intend but what ever...
seem to be the same to you.

To come back to 144 Hz for example, how can that display all different framerates right without having changed the smear, I don‘t know if this is the right word, but if you do anything to watch it on another multiple than the native refreshrate matching for that framerate, you will change the picture to be clearer or more smeared. I mean for describing the motion speed, the filmmaker can choose the right settings in the cam. But using matching refresh rates doesn’t affect that sort of thing.

because an LCD is sample hold so the refreshrate doesn't matter in this cease the smearing is always the same.
to be absolutely clear here an LCD is not displaying content accurate because it takes to long to switch the pixel and OLED is still sample load based to the motion resolution is very low.

I can live with that that I am a „purist“, but if you have a 50fps video and watch it at 60Hz how can this be smooth especially at panning shots. This is another reason for me to use matching refresh rates.

the number of TV that can't do 50 hz is quite big just so you know. pal support is not mandatory in NTSC countries.

good to have smoothmotion still far from optimal situation for it but better then nothing.

Hi, just wondering, why does doubling refresh rate make it look sharper?

is obviously doesn't do that on a sample hold displays like an LCD or OLED. the image displayed on the screen is the same the pixel stay the same time in the same state.

on refreshrate based screens like plasma and CRT it lowers flicker but increases ghosting you have to choice one of them.
for 24p you have the ghosting anyway so higher doesn't hurt for 60 fps content it hurts motion resolution if displayed at 120 hz.
Every better hardware player can do it, but I like a software player best, for best future proof.

I bet that every Blu-ray player above 50 Euro does support 24Hz output when the movie starts. My good old ps3 does that also. I am not using it anymore but it did it already 10 years ago.

who cares if the screen can't do it.
Asmodian, are you referring to me with post #58142 (https://forum.doom9.org/showpost.php?p=1892746&postcount=58142)? If so, I cannot see the connection. What did I wrote and must admit don't understand that. Please use easier words for a non-native english speaker :p

typical result if your screen is motion interpolating with smoothmotion. so much about purist.

smoothmotion exist for device with problem in 24p mode or screens that simply can't do it like PC screens to keep the creators intent.
the motion interpolation on a TV is created to smooth the motion by creating fake frames which has nothing todo with the creators intent.

if you don't have that problem why should you use it?

just to give you an example samsung TV treat 24p source international wrong and create a 3:2 judder unless you set the motion interpolation setting correctly to custom 0 0.
LG usually needs real cinema to be enabled or they also do it intentionally wrong.
sony well i let you guess how they handle this situation to display 23p as the creator intent and what you need to setup to get true 23p.

just to show you how dumb TV brands are.

[Klaus1189]

But on the small TV with 60 Hz panel it does look different when I feed it with a 24fps video in 24Hz and with 60Hz. When 60 Hz is applied I see the judder. I did a blind test and when I checked it with OSD info I got always right. Strange, I think I must buy new eyes.

I disabled "Samsung smooth motion" on all my Samsung TVs. :p

Did you read it carefully what I wrote? Why should a slow pan on 50 fps video be showing at 50 Hz the same flickering like it does when set to 60 Hz while doing madVR to smoothmotion. Download some pan shots and compare for yourself.
I turned on smooth motion in Samsung TV and it got very smooooooooooth, so it was definitely off.

Why are again so challenging :(
This behavior doesn't make it easy for me to come back to help people.

[huhn]

how do you even know if a german TV is 60 hz? i know no one that test them.

and if you are so so sure about that tell that's testing sites and question the existent of these option and why rtings tests this if it it's doing nothing at all.

Why are again so challenging
why are you so ignorant and only read the parts you like and ignore the rest.

Blur reduction at 10 gives smooth image without any ghosting. Judder reduction at 5 stops the skipping look when the scene pans around. I've tried with them off and its just way better with them on. Still keeping the film look and no soap opera effect which i hate personally. Try it

[Klaus1189]

I don't get the question, do you mean displaying a 60 fps video or what exactly?

and if you are so so sure about that tell that's testing sites and question the existent of these option and why rtings tests this if it it's doing nothing at all.
My main TV is a Q9FN and rtings tested it:
24p Judder
Judder-Free 24p <- this one is relevant for my usage
: Yes
Judder-Free 24p via 60p
: Yes
Judder-Free 24p via 60i
: No
Judder-Free 24p via Native Apps <- this one is also relevant for my usage
: Yes

The Q9FN is nearly judder free. When playing 24p content through a 60i source, like from a cable box, the Q9FN was inconsistent in removing judder. In a 24 frame test, there is judder in only 2 of the frames. This probably won't be noticeable to most people. Like other Samsungs we have tested recently, this result is unexpected and we will retest this with future firmware updates.
See full details here:
https://www.rtings.com/tv/reviews/samsung/q9fn-q9-q9f-qled-2018

IMPORTANT:
I think I made a mistake, the second TV, the small one I use with madVR is a UE43KS7590UXZG and I thought it has a 60 Hz panel, but it seems it has also a 120 Hz panel, so please forget the 60 Hz panel thing, because of this wrong info in my head I thought a 60 Hz panel is also capable of doing perfect 24p.
But if you look the the rtings page and hoover the mouse over the "?", there are lots of TVs which are rated "0.0" and if I look them up in the test they all use a 60 Hz called panel and can'T do 24p native.

SORRY for my mistake, but since I use 120 Hz panels there's nothing wrong with refresh rate changing, because on these two displays 24Hz looks good to me.

So if a user has one these TVs it will definitely be better to use smoothmotion at 60 Hz output as best usage with this TV. But if you have a 120Hz pnale in the TV the TV is able to do correct 24p? Correct me if I am wrong.

Is there a way to save the 12bit RGB full color depth setting in nvidia control panel for 4k30hz resolution so that it gets selected during movie playback, even if the rest of the time the resolution is set to 4k60hz 8bit RGB full?
If I set the resolution to 4k30hz 12 bit RGB full and then change the refresh rate to 60hz, the 12bit color depth is selected during movie playback until the next reboot but I'd like a permanent solution for this.
I'm using the 4k30hz 12bit setting because that's the only way I get (almost) no color banding on my LG C9.

Do you really have "easy visible banding" when you let Madvr dither everything to 8bit and send this as RGB to your LG C9 ?
Something must be very wrong in this case !

I'm unable to see any difference related to banding between 8bit dithered RGB and any other 10-12 bit signal on my system.

I'd think that your LG C 9 must be the cause of banding : maybe some internal processing from the panel is causing the banding.

Have you tried "PC" mode on your LG ? Still banding visible ?

[huhn]

I don't get the question, do you mean displaying a 60 fps video or what exactly?
screen in different regions can have different panels making it hard to buy one.

everything on rtings can be wrong just because you have an german version.
The Q9FN is nearly judder free. When playing 24p content through a 60i source, like from a cable box, the Q9FN was inconsistent in removing judder. In a 24 frame test, there is judder in only 2 of the frames. This probably won't be noticeable to most people. Like other Samsungs we have tested recently, this result is unexpected and we will retest this with future firmware updates.
See full details here:]
because this screen is supposed to fail in two test try this:
The Samsung Q90R can remove judder from any source. To remove judder set Auto Motion Plus to 'Custom,' and Blur Reduction and Judder Reduction to '0' (if you don't want motion interpolation).
that's what i mean with motion interpolation 0 0.

and about the 60 hz panel sony found a way there are always exceptions to anything:
https://www.rtings.com/tv/reviews/sony/x800g
2 hard indicator that this is a 60 Hz panel are no frame interpolation to 120 hz and no Judder-Free 24p via 60i which needs a 120 hz panel to do the app thing is an indicator too.

Dear Friends

I would like to build HTPC and use the newest versions of: MPC HC + madVR + LAV Filters.

I would like to use this HTPC in two scenarios:

1. Only .mkv files - remuxes, backups from my physical UHD collection, such as: 3840x2160p @23.976 (almost every movie) and @24.000 (some of them) and @60.000 (only one movie: Billy Lynn's Long Halftime Walk), BT.2020 HDR 10bit YUV 4:2:0 + audio passthrough to my Onkyo TX-NR686 (Dolby Atmos, Dolby TrueHD 7.1, DTS:X, DTS-HD MA 7.1) with display projector: Epson EH-TW7100 4K HDR BT.2020 10bit.

So there will be no upscalling, downscalling needed at all. Only 4K HDR BT.2020 10bit YUV 4:2:0 to 4K HDR BT.2020 10bit YUV 4:2:0.

I will use an option in madVR: HDR passthrough to display.

2. I would like to watch also a YouTube in HDR, which is needed a codec VP9 v2.

So my question is, what is the cheapest PC components to buy, to meet requirements - watch movies in above scenarios without any stutters, judders, problems at all, just smooth playback?

Sincerely

[huhn]

the: https://en.wikichip.org/wiki/amd/ryzen_3/2200g#Graphics

but you should find a user with that APU first to make sure the VP9 profile 2 decoder is working properly. lavfilter fallsback to software on the new navi GPUs pretty much at random files (nearly for sure an GPU driver problem).

it's not recommended to use HDR passthrough with a projector.
even with relative low HDR->SDR settings it's not hard to beat an projector in tone mapping.
but a weak GPU like this VEGA 8 is not the best choice for this.

[DMU]

@VAMET
the: https://en.wikichip.org/wiki/amd/ryzen_3/2200g#Graphics

It would be a better choice if there weren’t the unsaturated (https://drive.google.com/open?id=1WCioSIElyKfg51sn5zFc-oVLwUUA2VPm)/wrong (https://forum.doom9.org/showthread.php?p=1892452#post1892452) colors issue in "hdr passthrough" mode, which was discussed here on the last pages. It seems that this is an issue for all AMD GPUs, so turn your choice in favor of Nvidia.

[VAMET]

Dear DMU

I understand, but what kind of CPU and GPU will be enough for my scenarios 1 and 2? I will be not using this PC for gaming, only movies 4K HDR BT.2020 10bit YUV 4:2:0 and YouTube HDR.

Sincerely

[Devrim]

So I just upgraded to Windows 10 and...I forgot to backup my settings...

Anyways...What is the best hardware decoder (Quality over performance!) to use with madVR on Intel CPU/nVidia GPU? D3D11 (Native or Copy-back) Or DXVA2 (Native or Copy-back?)?

[mclingo]

Sincerely

if you just want a straight 4k playback system with no frills any 4k/HEVC/HDR capable card will do this, you could go as cheap as an NVIDIA 1030.

However if you are planniing to tone map which is highly recommend for projectors spend all you money on your gfx card and go budget on the rest i'd say.
