That old saying; "If it ain't broke, don't fix it" comes to mind.

Thanks for the clarification madjock. I thought this is about bitdepth, which would have been more important.

just been having a look again at how MADVR deals with really poorly mastered and heavily compressed material. This clip is horrific on OLED but what is odd is that the only option that does anything at all to mask some of the problems is the debanding filter, random noise and compression artefcts do nothing at all even on 14 with the macro blocking which makes me wonder what these are actually doing, they just seems to blur the entire screen for me.

debanding on high does a reasonable job of masking the major issues that a crush doesnt fix but damages the over all PQ shaprness quite badly.

Does anyone use reduce random noise / compression artefacts, if not then maybe we could scrap these and have something that specifically targets dark low IRE areas and shadow like what was suggested a couple of pages back.

I really think this should be given some dev time by MADSHI when he's got HDR up to scratch as more people are getting OLEDs and there is just so much poorly mastered material out there.

clip:

I know you cant polish a turd but MADSHI could maybe spray some MADVR fairy dust on it and make it smell nice.

Oh yeah a setting for denoising independant of standard denoising for a customizable range would be very nice.

Exactly what I have been thinking and trying lately with madvr and my oled. I was trying all kinds of settings combinations but nothing helps,,, Reduce Random Noise might help but the value "1" is too strong , we need values between 0-1 and it could use a bit fine tunning.

It could be great if there was a high quality noise reduction + option to apply it on near black zones in a scene...

yeah like noise is the problem in this video.

time to write a denoiser for 16x16 macro blocks surrounded by literal nothing this surely will fix the issue...

Hi because I am still on a gtx 960 4g which delivers a great picture via madvr on Lg oled and after tweaking some settings (thx to the feedback of the community) and match refresh rates in madvr it is even more hard to think about a gpu upgrade.
My Favorit will be a gtx 1070ti but I am also looking into the amd section rx 580 up to vega 64
Could be possible but I think more than a vega 56 won't be possible without changing the power supply.
So my question is can some rx 580 user tell me what the highest settings are possible to use within madvr for upscaling DVD and blu-ray to 4k output. I am using an LG oled which is calibrated and 3d lut in madvr.
Price of the rx 580 is nowadays amazing and for the 1070 ti I was to slow to catch them at a good offer. I want also the gpu upgrade not only for madvr but I do some video editing and could also get some benefits on a stronger gpu.

Even given the low prices for the Rx580 now you'd probably still be better off with a 1060 6GB for madVR, if you're doing more than that then sure the RX580 is more worthy of consideration.

I've recently bought a G-Sync monitor and now have a small problem and hope that someone can help me.
Although I'm not using fullscreen exclusive mode I get a short black flicker when I switch between windowed and fullscreen windowed mode. It seems like my monitor is switching G-Sync off when entering fullscreen windowed and switching it on again when leaving it - at least that's what its OSD says. This is especially annoying since it also happens when the seek bar is shown or hidden.

I'm using MPC-BE as player, but the problem does not happen with EVR-CP, so it seems to be madVR specific.

I've already configured the Nvidia driver to not use G-Sync for MPC-BE and this also had an effect (madVR shows the "normal" refresh rates - before they were way different), but doesn't seem to be enough?

My madVR settings:

* Fullscreen exclusive mode off
* D3D11 for presentation
* Native D3D11 decoding with LAV

My Nvidia settings:

* G-Sync globally on for fullscreen and windowed modes (I need this for games - it seems like it's not possible to globally disable it and just enable it for specific games)
* Added MPC-BE for custom application settings and configured it to use fixed refresh rates instead of G-Sync

Anyone an idea how to fix this?
In other words, how do I completely disable G-Sync for MPC-BE/madVR while keeping it active for games?

Curious about how future Dolby Vision could work for HTPCs.

As far as I understand things, I think Profile 5 support is more likely to come. That "fuses" the two layers used on BluRay UHD in a single video stream, for the TV to interpret. That's what Apple TV 4K uses, if I'm not mistaken.
We currently can rip BD UHD and keep Dolby Vision, but it's Profile 4. I guess that would require a change in mkvtoolnix to have mkv handle two video streams concurrently. But then something would need to put the two streams together, right?

My question is: at what stage would this "fusion" need to happen? Decoder? Renderer? So, basically, would it be a job for LAV or madVR?

I see you have a C8, what you may be seeing is the flashing near-black macroblocking these all seem to have.

Hi,

There is a very simple fix for those who want to use a g-sync monitor with madvr but keep g-sync enabled for games (both fullscreen and windowed): add your media player player's .exe to the Window Media Player built-in nvidia profile (can do that through the NV Control Panel but I recommend using nvinspector instead).

Nvidia has done some magic and it works with this profile only (well there's a few others that work like Internet Explorer etc. but yeah). If you try to use a game profile or make your own custom profile it will not work properly and you'll end up with g-sync completely disabled for your games and other weird bugs. You can try adding madvr's .exe to the profile too but I have never had to do that.

Also I recommend not using fullscreen exclusive anymore (in madvr), I've had some weird issues with it on Windows 10 with a g-sync monitor.

kalston, thanks for the suggestion, but how do I add a new exe to the existing Windows Media Player profile? Even when I first select "Windows Media Player" and then add the MPC-BE exe it just creates a new entry in the program list for it.

As I've already written, I'm not using fullscreen exclusive.

It's a bit clunky to do with nvidia's Control Panel, I've basically given up on it and just use nvinspector instead.

Anyway just use this: https://www.techpowerup.com/download/nvidia-inspector/
in the archive you will find "nvidiaProfileInspector.exe": start it and then look up for the Windows Media Player profile in the box on the top left. Then next to the red cross (delete profile button) you will see a "add application to current profile" button. Simply use that and click "Apply changes" when done.

Does anyone know how to fix the brightness issue with external subtitles when HDR is enabled?

I tried lowering white color in xysubfilter, but this causes a new issue in which the subtitle merges with the movie in some scenes.

Edit: Lowering white color does sort of "fix it", the problem is external subtitle placement. If the subtitles are placed inbetween black bars and the movie itself, it will look weird as the subtitle part inside the black bar looks normal but the subtitle part inside the movie will look less bright and a bit weird as if it's mixing itself with the movie. I can post a screenshot tomorrow.

https://imgur.com/a/t8eGSZZ on average it repeats about 900 frames before the video kicks in.

Once the video eventually begins playing I have no other issues for the remainder of playback.

MPC-HC 64 bit (tried both 1.7 and 1.8 builds)
External Lav (latest night build 73.0-1)
MADVR 92.17 (CPU Queue Size 16 and GPU Queue of 12)

If I use EVR custom Presenter instead of madvr I get Instant playback. I've tried uninstalling and reinstalling madvr as well.

- toggling between options for fullscreen exclusive mode and Direct3D 11 for Presentation had no effect.
I'm having this issue too.

I first ran into this issue with the 1803 update. Disabling focus assist solved it then, which I shared my experience here and seemed to help a few other members. Now after updating to 1809, I have the same problem again, and focus assist remains off.

Has anyone found a solution to this? Every solution I've found in this thread has been to revert to an old version of either madVR or windows. I'm hoping for a more permanent or ideal solution. I've tried playing with different settings and updating the drivers etc. to no avail.

I have 3 computers running madVR and two of them have this issue. What I notice is that the two computers experiencing this issue, the composition rate changes from 59.94hz to 60hz. I don't remember this happening prior to 1809. My PC that doesn't experience this issue, the composition rate stays the same between FSE and windowed mode (59.94).

do the kinds of calculations that madvr use for ngu upscaling benefit from the performance improvements in Quadro/Titan video cards versus RTX consumer cards?

just wondering if Quadro cards in general perform these kinds of calculations much better than consumer cards by design because Nvidia does gate off or restrict certain computations or floating-point depths. thank you.

[QUOTE=Ampallang;1856891]Hi Warner that works very well now I will try to set for the sources some fine tuning. But the pas far as I can see it looks as good and better than before and I have the feeling that it take less resources in hdr.

This fixed my issue as well , thanks Warner !

I doubt it, because of the restrictions of double precision it seems rarely used outside of raw computation
