Oh ok, so If I use NGU Sharp, it'll still use my GPU?
I thought anything other than DXVA2 settings in MadVR was a CPU based algorithm.

Ah, I see how to change chroma scaling - thanks!

Yes, NGU Sharp is run on the GPU, there are no CPU scaling algorithms in madVR.

DXVA2 uses the GPU's hardware scaling, which is very fast, but everything else uses the GPU's FP32 capabilities.

In madVR only black bar detection and IVTC runs on the CPU.

Hio, turned my HTPC on today to find a really odd problem i've not seen before with MADVR and KODI DS, i'm posting here as its only MADVR that has this issue and its happening with all builds of KODI DS, DS and DS BG.

when I play a movie it plays but the movie is shifted to the right and not centered on screen, I also have no focus on the movie and I can see my KODI gui at the bottom and the focus is on that, its like windowed / FSE is all broken on my machine, it was working fine last night and nothing has changed, i've chucked everything at it bar a new windows build.

I've just done a system restore to yesterday which hasnt fixed it either suggesting it may not actually be my PC, its odd though, it only happens with MADVR and KODI DS, if I play the movie in MPC/HC /BE its fine, if a use the standard renderer in KODI DS its fine.

I've also tried wiping MADVR and using base settings, doesnt even work if I use a base MADVR/KODI DS install.

Any ideas?

turned out to be an issue with the test build I was using, when I went back to stock .17 it was ok, very odd, its like MADSHI put a timeout lock in this build, it just stopped working, I thought it was working in MPC/BE and HC but they had both defaulted to standard renderer and MADVR wasnt loading at all, I had been just ignoring the UPDATE MADVR message, it cant be that though I guess, i've been using this 117 build for ages.

i'll try 118

Builds as of 114 have expiration dates.

They will start by popping up a message, and then later stop working.

Latest as of right now is build 128.

madshi said that he will always release a new build well before the previous build expires.

He also said if you want to run an expired build to just change your system clock. There are also ways to just change the system time that an individual program (madVR in this case thinks that it is).

ffs, I didnt know they were going to actually stop working, you'd think there would be a message saying MADVR is now disabled or something, plus he doesnt actually post the updates centrally anywhere, there is nothing on the MADVR website.

Latest test build. Keep that URL and simply check for newer builds every once in a while by changing the last digit.

Here's the thing....they aren't official builds. They are test builds meant to help improve the HDR tone mapping code. That is why they aren't listed anywhere but that particular thread. So while you can use them, they aren't necessarily meant for daily use. The timeout was put in place because madshi was concerned that companies were creating madvr HTPC's that they were selling to customers. That isn't what it was designed for. Please note I'm not arguing for or against, here, simply stating the information.

They are posted in the 1 place they should be.

The HDR tone-mapping development thread as that is all they are meant for.

They are meant only for testing, not for daily use or general public consumption.

Is the latest test version working with Dolby Vision MKV files?
Some samples are available here: https://www.makemkv.com/download/dvtest/

Best and quietest hardware configuration for madVR?

At the moment, I don't have a PC capable of running madVR at anything other than the most basic settings. I can't even use it to activate HDR when playing rips of my Planet Earth II UHD Blu-rays, which rather ruins the picture quality.

I'm now planning to buy a new PC and would appreciate guidance on what configuration would offer the best madVR performance without causing much fan noise. Would a GPU that's more powerful than madVR requires run more quietly than a lower powered GPU that just meets madVR's high end needs?

No doubt such matters have already been discussed in this forum, but I don't have the stamina to wade through 3066 pages

No. And it's not likely to, either.

It works fine with them. It just ignores the DV data and uses the HDR10 data.

DV is not that simple the DV on UHD BD is backward compatible but DV in general doesn't have to be it can even use HLG or even SDR.

here is more "information":

Well, yea, that I very much doubt was the question they were asking.

It's mostly about the cooler, but a more efficient card also will do more work for less heat. If you can get them, a midrange AMD 6000 or Nvidia 3000 should do the trick, but they're extremely hard to get right now. You'll likely be fine with a 1650 Super or something like that, but previous gens don't support HDMI 2.1 so that might be a consideration.

Years ago I used to buy low-mid-range cards (about maybe 70-100W) and replace their coolers with an Accelero S1 so I could run them fanless. After that I just got lazy and the last midrange card I used is a GTX 1650 Super with a pretty basic cooler and it's kinda noisy. Something like an Accelero Mono Plus should work fine for midrange cards. It should still be better than most coolers that come with such cards. You can probably get one with a very nice big cooler included but they're usually more expensive as well.

The thing is that low-midrange cards tend to have low to midrange coolers. I recently could get a 3070 FE and it's silent when running madVR and 4k HDR content because the card is overkill for video, thus its higher TDP cooler doesn't even break a sweat. In fact the fans don't even turn on when playing video at all.

But of course that's a way overkill way to go silent if you're only doing video and not playing games.

Thanks, Andy. That's very useful information. There are two PCs in our main living room (neither of which can cope with any serious use of madVR). One is an Intel NUC that serves as an HTPC and which runs very quietly in a corner away from the seating area. The other is an older Dell Precision Workstation and is my primary computer. It's closer to where we sit, but is normally idle and silent when we are watching the TV. That's the PC I'm intending to replace, so a low fan noise level would be very important to me when using madVR on this new machine.

Do the fans on your 3070 FE start running when madVR is at its highest settings? For example, I'm assuming that using it to upscale HD to 4k would be more demanding than running native 4k with HDR.

I have an issue where HDR videos trigger my display into HDR mode, despite having set a rule to tonemap HDR content... This happens like 50% of times, not always.

Also I've been wondering, there are lots of 1080p content, as it has managed to become a standard for videos now for some years. Meanwhile 4K is now the de facto resolution for Smart TVs, despite lack of 4K content (only a few UHDs and a few non-upscaled games).
2160p being double the size per dimension of 1080p I thought it could be a great idea to have an static option for nearest neighbour as it just takes a single integer scaling. This means less PC resources and power consumption and unadulterated 1080p image quality.
NGU can look nice on digital camera films where there's lack of grain, but films before 2005 where grain is common turn into a grain smear fest, not unlike some FFT based denoisers. Looking forward to set up some rules with nearest neighbour.

if you have "output video in HDR format" unticked in devices settings for your display it should never output in HDR mode and therefore not trigger the TV's HDR mode surely?
