madVR - high quality video renderer (GPU assisted)

[petran79]

tearing problem solved for the time being.
Solution? Had to enter Nvidia Control panel Manage 3D applications and choose "Restore Defaults". Thing is I hadnt tampered with anything at all. Had to reinstall drivers because all of a sudden Nvidia Control Panel would not launch.

Windows 10 and Nvidia are even more screwed up than in the 90s....

Then if the content needs more than 18Gb/s bandwidth in 12bits (say you play 4K60p content), the driver switches automatically to 4K60p RGB Full 8bits 4:4:4, and back to 12bits when the playback is over. There is no need for a script. But it doesn't work the other way around. If you are in 4K60p when you select the bandwidth, then you CAN'T select 12bits, you're limited to 8bits, simply because it's not possible to select more than 8bits in 4K60p 4:4:4.

Does this end up with your desktop running at 23.976Hz?

What AMD card do you have, the RX550 ? Do you upscale 720/1080p to 4k with madVR ?

Only if you select 23p by default. Once this is set, you can set it to 60p if you prefer, but it will be 8bits. It will then switch to 12bits if you launch 23p to 30p content.

I prefer to have my desktop at 23p so that I limit the number of HDMI syncs (15 secs with the JVC!) when I launch content, as 99% of my content is 23p. That way going from MyMovies to content and back is seamless and near instant.

If I was gaming more often or using the HTPC for other things, I would set it to 60p, but it's an almost 100% dedicated HTPC, so it's set to what works best for video playback, and that's 4K23p RGB Full 12bits 4:4:4.

Hi, RX550, it doesnt really have the power to do any high quality upscaling in MADVR so I just let me TV do it.

[HillieSan]

Why not? MadVR is typically used for upscaling. The RX 550 will do fine with Jinc, SuperRes and perhaps also with NGU medium.

The idea is that madvr performs upscaling better than your TV. This is the case for my TV and projector.

[el Filou]

Jinc should be fine but NGU could be tricky, huhn says the Polaris cards have problems with NGU.
OTOH, I also have doubts a TV would upscale better than Jinc.
@mclingo, have you tried comparing your TV's upscaling with madVR's Jinc?

[huhn]

the really important part is the Vram is it a 4 gb or not?
NGU low or med may wotj with 4 GB and it is not like you have to use NGU there are a lot of good alternatives in madVR.

in my personal experience it is not hard to beat a TV in scaling.
my panasonic TV is so bad at scaling that lanczos AR wins hands down. Tv scaler are usually totally over the top try hard scaler.

i tried it a long while back on my RX 480 and it wasnt 100% smooth on higher settings, no point using lower settings as my TV will do just a good a job.

I guess its worth another look though.

what do you have your chroma and image upscaling set too?

The other issue is though what happens with 3D MVC stuff, that will only work in 1080p, I didnt try that last time.

good call, glad I tested it again, seems their drivers have improved, I can set NG sharp medium on image and jinc on chroma and get smooth playback, 3D MVC still works as my TV wont process a 3DMVC signal higher than 1080p.

i'll have a tinker and see what I can push it to.

EDIT - sadly best I an do on 4k HDR material is lanczos on chroma upscale, anything more and i get minor gliching, to my eye is see no difference with my TV upscale with super-res on LOW at this level.

LG OLED 4k upscaling is actually pretty good, it also has a superes option which is also very good.

I also had issues with my RX 480 in the beginning but after updates of madvr and LAV things became stable and faster. Now, I use the RX 480 with NGU Sharp High, RCA (4 medium) and RRN (2).

Compare all scalers for chroma and you will see that Lanczos is just right :-)

Tip: Put dithering on Ordered Dithering to lower the processing time.

1st post. Been lurking quite a while and have learned so much here. Intend to help where I can and continue absorbing what is provided now that I've finally registered. Wanted to thank madshi for providing his creation we all digest and together help him refine. Special thanks also to nevcairiel visits and his Lav filter package as well as the MPC crew pulling all this together. Lastly to the posters, regulars and one-offs alike, who tirelessly endeavor to help others in a thankless task. I just want all of you to know your efforts are not taken lightly and this new member appreciates every single one of you.

@madshi --- I am not sure if you are interested in this but just in case you ever consider implementing BFI for 24fps video on 120Hz display in madVR, this might saves you some annoying moments figuring out this trick I just discovered:

There are several kind of AviSynth scripts floating around on the web which introduce intolerable flicker. Here are the wrong examples:

AssumeFPS(60000,1000)
Interleave(last      , BlankClip(last      ))
AssumeFPS(120000,1000)

Original = last
Black=Original.Blankclip()
Interleave(Original,Black,Original,Black,Original)

Here is the problem with these: FBFBFFBFBFFBFBF (The flicker is similarly annoying if you end up with double black frames in the stream.) The same thing happens if I send 48 fps (repeated "Frame,Blank" sequence) to madVR.

And this is how I got it working "properly":

F = last
B = F.Blankclip()
Interleave(F,B,F,B,F,B,F,B,F,B)
SelectEvery(4, 0,1)

I think you can see the trick. The result is a "rotated" sub-sequence in the stream: FBFBFBFBFBFBFBF (you never get FF or BB which would cause visible flicker).

The last script looks fine on OLED TVs (it achives the same thing on the LG OLED what Panasonic does in firmware on their LG panel based OLED TVs). The flicker is comparable to that of most PDP displays (which have black intervals by nature).

Can someone please help me understand something. I have the 1080Ti card and have always upscaled all my BDs to 4K. Ive always had the card set to RGB but today I was looking at the madvr stats and see no RGB in them. What it states is h264, 8bit, 4:2:0 > NV12, 8bit 4:2:0, Im sure in the past it always stated RGB.

I have tried to change the card to 444 and 422 but the madvr states always show as h264, 8bit, 4:2:0 > NV12, 8bit 4:2:0 regardless of what I change the output color format to on the card. Output colour depth only ever displays 8bpc, is all this right or is something wrong here for me?

[Asmodian]

It did not say RGB anywhere in the past, that is all normal stats. That line in the OSD is only about the INPUT to madVR.

Your example: 8 bit 4:2:0 video encoded as h264 is decoded by LAV and given to madVR as 8 bit 4:2:0 video in the NV12 format.

The output of madVR is always RGB with the line that mentions the DirectX version telling you the bit depth, e.g. D3D11 windowed (8 bit).

[70MM]

Thank you Asmodian for explaining. Where I saw RGB in the stats in the past is when I had my old Lumagen Pro in the chain, I removed it after many here said the Pro degraded my madvr signal. So with the Pro out of the chain and upscalling all my BDs to 4K the stats of h264, 8bit, 4:2:0 > NV12, 8bit 4:2:0 is absolutly correct, correct?

I should leave the 1080Ti card set to the following correct?
Desktop color depth = Highest 32 bit
Output color format = RGB
Output color depth = 8bpc
Output dynamic range = Limited

[Asmodian]

All correct except Output dynamic range is ideally full range, unless your display is better when using limited range (sorry, I don't remember what you had determined after removing the Lumagen).

if you like that "result" fine by me. but if you think LG OLED have special processing compared to the normal TVs. well...
@70mm
you asked that before and the answer didn't change full range RGB is in theory superior.

Everything is better without the Lumagen, Im happy! When I try full range the image is washed out. On limited Im getteing 16 / 235 correctly on my JVC 9900.
