madVR - high quality video renderer (GPU assisted)

I wish Oleds would just dither the near-blacks by default like plasmas did. This would solve alot of problems and only cause a bit of noise.

edit: madshi should implement some algorithm to madVR for Oled owners that does heavy dithering to near-blacks and less and less on brighter parts of the picture.

Madshi, if this is something you could implement, there's a bunch of oled owners who'd be forever grateful! I know you don't have an oled but we could test for you. On my C8, I have to have madVR dither to 5bit to get acceptable near-black gradation.

Hi there,
I'm using DisplayCAL and MadVR's test pattern generator to profile my display. I've just updated everything to the latest version, including video driver (GTX 1050Ti). MadVR's patterns are constantly flashing on screen, there is a double flash every three seconds. I have never seen this before. Is this intentional/known/am I doing something wrong?
Thanks!

How's performance on Vega 64 compared to GTX 1080?

[huhn]

there are not a lot of vega cards out there is considered an all over pretty bad card for consumer use.

even the 56 can spike to ~600 watt for an relative long time. and it is unclear if AMD makes any money with them.

so not that easy to find a user with it. it could be much faster for madVR use than a 1080.

Super-xbr 100 is a nice light weight option and my previous favorite but at 100 I feel is a tad sharp which you may notice as I did, at 75 however it should look fairly similar to NGU AA low.

Much bigger difference. I used xbr-100 for the longest time too. You can see here it's a bit too juiced up and in certain areas of cloth it feels like the colour is clipping. Thanks!

Does madVR support using DCIP3 as colour gamut instead of Rec709?

[tony359]

I'd like to update my last post

I found that the flashing only happens when FSE is enabled. I've now disabled it and all is good. Which takes me to the following question: is FSE still a good idea these days? I believe I read comments suggesting it's not really needed anymore.
Thanks

madVR supports all kinds of gamuts DCI P3 is one of them.

it depends on your system but you are usually fine without it.

Hey guys!
I have got an issue with the “automatically detect hard coded black bars” option. It won’t work when using D3D11 automatic (Native) Mode in LAV Filters. I know that it doesn’t work with DXVA2 native mode, but what about D3D11?
The option works when I use copy back mode, but rendering times are getting insane then. Is there any fix for that?

[sneaker_ger]

No fix. Black bar detection is simply not supported for D3D11 native and DXVA2 native.

[OnkelB]

That’s what I thought, but I couldn’t find that info anywhere. Thank you for verifying!

Thanks.
How do I find out if I am within the "usual" systems?

If you have no problems with HDR, high bit-depth and custom refresh rates, you don't need FSE.

we've discussed this before, it isnt that OLEDS are particularly bad at near black, I keep hearing this but I dont see it. I have a first gen OLED and I can tell you that it you feed it a good image you get one right back if its setup right.

Where they struggle is poorly mastered compressed material where there is macro blocking at near black. An LCD will have exactly the same problems if they could do perfect black, LCD just masks these areas as its all just a grey mush. My OLED cant fix this, Later panels added a black crush and some extra processing to hide some of this but mine has none of this so I use MADVR, I guess you could say i'm seeing the picture as it is, warts and all.

I do agree however some extra dithering patterns near black would be very useful, especially for TV rips. Some of the netflix, amazon and particularly sky stuff has been so bad over the years even though I was paying for it I sometimes had to download the episode so you I can run it through MADVR and apply some image processing.

BBC are the worst offenders IMHO, there compression is horrific, Peaky blinders has been completely unwatchable at times due to streaming compression artifacts.

Trust me, it's different with 2018 OLEDs. For some reason they are pumping brightness through near black and causing near black artifacts to flash brightly. Pause the video and the flashing stops, press play again and the crazy flashing starts again. This does seem to be a bug because sending the same content as bt.2020 instead of bt.709 and this flashing does not occur. That isn't a viable solution but luckily dithering to 5bit also solves the issue (no flashing). This also was not an issue with the two C7s I had. Or any other TV i've had lol.

No HDR involved but never managed to get custom refresh rates to work - it's on my to do list to investigate better.
What do you mean with "high bit depth" - I mean, I know what that is but how does it apply here?

Thanks

If that is the solution, the panel manufacturer really ought to have a look at the problem tbh.

'Solves' is the wrong word. Effectively reduces the effect would be a better way of saying it. And sending bt.709 content as bt.2020 also effectively reduces the effect...I mean, how does that make sense, other than a processing bug in the TV? But yeah, not great for a so-called 10bit panel. Some dark content is downright ugly on this. Thank the lord madshi for madVR though!

[ryrynz]

What about changing the range a bit at the black end? Does that affect it much?
