madVR - high quality video renderer (GPU assisted)

[Sparktank]

+1 for "add grain" as separate feature instead of being "upscale refinement".

When I use SVP, I don't know how to hack the scripts to include AddGrain for FFDShow. And FFDShow's own filter is nowhere near nice enough as AVS AddGrain.

Even at 4, it doesn't seem to do as much as what AddGrain AVS can do.

HDR is working again with nVidia 416.34 drivers

Indeed it is. To clarify this means in windowed mode not just FSE.

[brazen1]

I can confirm nVidia 416.34 are switching HDR in FSW and FSE again. Same with 3D which is a first for my system.

[ajp_anton]

100% view is the screen as it appear in the media player. The encoded video size is the original pixel count of the source. I haven't tried the second option, but I think that is what it means.Nope, for me xxx% view always creates a screenshot that is xxx% of the encoded video, no matter how much I've zoomed. So "100% view" is always identical to "encoded video size".

[huhn]

did you try an anamorphic video. the view and encoded size should be different on these.

[famasfilms]

Latest Nvidia drivers have fixed HDR, but now the madvr display mode switching doesn't toggle my LG OLED from "PC" mode to "Home Theatre" and my calibrated picture settings.

Ever since I got the TV and the calibration done it's been set to PC mode (because I use it for other stuff), and madvr has been setup to switch display modes - the change of display mode would automatically change the TV to "home theatre" which is where the calibrated "night" setting was

[mkohman]

Hey guys thanks to @Onkyoman, I have now created two profiles for HDR and SDR within madVR for slight saturation boost for HDR content..

On my JVC projector I have also created 2 profiles.. First one is HDR to SDR and the second one is just SDR..

Is there anyway that when I am playing a bluray (1080p) upscaled to 4K via madVR using REC709 on the JVC's SDR custom setting I created, is there any way to get madVR to get the projector to detect that it's playing an SDR movie and to change it to the SDR profile on the JVC and visa versa? rather than me doing it via the projectors remote control? Thank you guys in advance..

try the send bt 2020 option under calibration.
not sure how your device exsactly handles this but if you have it by default in bt 709 mode and add this bt 2020 option to the HDR profile it should switch if it understand this setting.

[blaubart]

Wow Nvidia was listening to my laments! :) 416.34 (still in W10 1809) and madVR switching HDR again. AND switching it to correct black/white clipping, yeah!

During all my posts I had to switch HDR manually through Windows Display settings -> aha and if I do that now madVR still shows wrong black/white clipping. So seems to be a Windows>Display settings>HDR bug or bad YCbCr cooperation with madVR.

[pantagruel68]

Hey Guys.
Can someone explain me why when I watch a movie when chosing 1080p resolution I get very close To 23.976 ( about 23.9758) with my gtx 1060 but when selecting 2160p I get 23.978?
Thanks

Actually, he may not even need the profiles in the PJ. Here's what I do for Panasonic UHD SDR TV:

In calibration section, I set colorspace to BT.2020 and select "report BT.2020 to display. MadVR should remap BT.709 HD bluray to BT.2020 , and the switch should put the PJ into BT.2020 mode automatically. With HDR content, if set to "tone map HDR", the passthorugh of BT2020 should also be automatic.

HI Madshi,

i just replaced my old ati 5770 with a gtx 1060 (3gb) , but i have major dropped frames in madvr when playing video since i installed this card (about 10/sec). this is even with default madvr settings, and using mpc-hc (64 bit).
pc = i7-4770k cpu, 32 gb ram, ssd 500 gb, and new 1060 3gb gfx card on a win7 64 bit system

other video players work fine, eg cyberlink powerdvd, vlc, mplayer without madvr is also ok, etc
i have tried several gfx drivers (latest whql, version on the install dvd, best recommended by other users for similar video card etc..), all no solution. also checked for mb driver & bios updates etc (all are up to date). gfx card has no alternative bios release to try.
i did search for other users w madvr reporting similar problems but the main suggestions (from yourself earlier in this thread for ex) was to turn flux off and not use gpu-z, didnt seem to help in my case

https://ibb.co/eQ0VZU
https://ibb.co/eQ0VZU

when i first installed the new 1060 gfx card i thought it was working correctly, even was able to play some 4k HEVC files smoothly(downscaled to my 1080 tv over hdmi) and was really impressed with the quality of the video image (as i was expecting from madvr from my old ati card use in previous yrs), but then further testing with 1080p and 720p files (mp4 and HEVC) over the following days all started to have similar severe dropped frames (tried lots of settings in madvr options, but now even default settings with all enhancements off now cause dropped frames 10/sec approx)

i have reset madvr to defaults, uninstalled and reinstalled mpc-ht etc, sadly no solution found so far. cpu usage stays low @ 30% approx, and gpu load is also low @ approx 30% with only 900 mb of the 3 gb vram used (as reported by gpu-z)

any idea what i should look at ?

your presentation times are terrible try windows 7 overlay.

i have tried the win7 overlay you suggested, no real improvement regretfully

thx for pointing to the poor "presentation time" as an indication of my poor video play, i can monitor that variable also now when searching for solutions

when i switch users on my win 7 install to admin user and play the same video files everything seems to run fine (using default mpc-ht and default madvr settings) see image
https://ibb.co/fFq7m9 this would at least suggest there is no hardware issues (ram etc ) or bios setup problems etc, also the current win7 install works ok when run from another user account to.

anybody know what else i can look at to find the cause of my high frame drops and poor render times? (as seen here https://ibb.co/eQ0VZU)

to me the current poor video play seems to behave as if some crumbs from a previous madvr installation might still be interfering somehow with my fresh madvr and mpc-ht re-install and their default setup

any ideas why the picture changes to black and white for me as soon as I set "highlight recovery strength" to anything else than 'none'?

Same here,, happens with 92.15 too.
GTX660, software decoding.

Probably DirectCompute related.

Exactly same problem here !

MPC-HC 1.7.13 (x86&x64)
MADVR 0.92.17
Geforce 650Ti
DL580G5 (4xXeonX7460)
Win10 1803

it worked fine before (DirectCompute ?)
And it possible to be able to choose the old algo ?

Guys, who doesn't have laptop (Optimus)? I do, unfortunately.
It's definitely DirectCompute related.

Edit: it's fixed in madVRhdrMeasure10, just wait for the new release. (Although my laptop doesn't have enough juice to use both "compromise tone & gamut mapping ..." unchecked and "highlight recovery" at the same time :) )

Hello!

I am soon to be an owner of a Inno3D GeForce GTX 1050 Ti 1-Slot Edition HDMI DP 4GB. How do I want to be scaling 540p, 720p and 1080p, respectively, to a LG OLED55C8?

:thanks:

[brazen1]

Khaled, use FSE Full Screen Exclusive.

[ryrynz]

How do I want to be scaling 540p, 720p and 1080p, respectively, to a LG OLED55C8?


The answer is, however you want. Most would use NGU (any variant) for their luma/chroma upscaling and SSIM 1D/2D for downscaling.

[Crimson Wolf]

Khaled, if you have anything open like right-click mouse and menu, it will be 8-bit until that menu is closed. If nothing is open, and it's still 8-bit, try rebooting. If you still have issues, try reinstalling the video drivers.

while you may not need that.
sending bt 2020 to a screen that is not bt 2020 is not ideal in my book. the screen needs to do heavy processing.

this is totally different if you run a screen in native mode and 3D LUT correct the image.

on projector it's an even bigger problem.

[SirSwede]

Okay. Does it matter that it is an old processor and old ram? All that Madvr needs is a good graphics card, right?

Also, someone told me that the TV is better at scaling these resolutions to 4K, than Madvr, which is not the case, right?

[blu3wh0]

So I spent some time testing the dynamic tone mapping on my LG B7 OLED and the latest pixel shaders for HDR in the test version 9 (with saturation boost +15, peak 750 nits, output in HDR, and measure peak). Overall, both the dynamic tone mapping and the pixel shader attempt to do the same thing, except for one key difference. The dynamic tone mapping appears to affect the whole image, while the shaders mostly impact only the highlights or sources of peak brightness. I'm not sure if this is the way it's supposed to work, but it's what I see. This is even more effective where working with a 4000 nit master, which the dynamic tone mapping helps with, but no where near as accurately as the shaders. An example of this is the bright green spear cut that is one of the test shots. For 1000 nit masters, the impact on the highlights between the two is very similar. I did see some instances of color tone changes with the shaders, but again I can't tell what was supposed to be correct in the image. Regardless, either would look normal if you didn't switch between passthough and shaders. I've only tested a few movies, but so far this is very promising and enough for now to try using the HDR pixel shaders for general usage.

[Anima123]

Do you guys know since when madVR requires DirectX 11 for advanced dithering method? As I remembered, it does not have that requirement during the testing of Diffusion methods.

[ryrynz]

Okay. Does it matter that it is an old processor and old ram?


If you're using a dedicated gpu then that can matter for file decoding performance but not for madVR but it can depend on age and core count.


All that Madvr needs is a good graphics card, right?


I used a gtx 960 for a good long time and it did well. I'd recommend anything similar or greater performance to get the most out of MadVR.


Also, someone told me that the TV is better at scaling these resolutions to 4K, than Madvr


There are good quality scalers used today on the latest 4k tvs but nothing that can match madVR's NGU in real time built in to any consumer display or readily available device.

Hmm...my line of thinking is this: no display is natively BT.2020, even the ones with the widest of gamuts need to remap from native gamut to a stabdard gamut ...even plasmas were not strictly rec.709, they had wider gamuts than rec.709 natively, there is always a 3D LUT or some other processing involved to get the colors in place (especially if a display has user-accessible CMS system) and these things should be optimized to run without hickups in all circumstances...

[blaubart]

I can't live without LG's "active HDR". It tries to mimic HDR10+/Dolby Vision by analyzing the whole scene and adjusting brightness and tone mapping per frame. I don't know if this is something madshi is working on or is even possible with madVR, but until/if this happens I'm sticking with LG's implementation.

It really helps with shadow detail in dark scenes. Often times madVR is simply too dark compared to LG with active HDR turned on.

You can use madVR for tone mapping and still turn on LG active HDR, but then you've got kind of a double tonemapping situation where the tv is trying to dynamically adjust brightness and highlights after madVR has already tone mapped. It doesn't quite look right IMO. Often times it will just make the highlights even darker.

[blaubart]

It really helps with shadow detail in dark scenes. Often times madVR is simply too dark compared to LG with active HDR turned on.

Switching HDR through Windows Display settings results here in madVR too dark black clipping. Since NV 416.34 madVR is able to switch HDR by himself again (Windows>Display settings>HDR off) - black/white clipping ok now.

I agree, however I can also clearly see the benefit of the pixel shaders in reeling in the highlights into the brightness range of the TV. The dynamic tone mapping on my LG clearly fails to do this accurately enough to recover the details, especially in the extreme regions. I've been testing out a higher peak nit value of 1000 to bring in the highlights more accurately towards something that dynamic tone mapping won't over darken or screw up.

I thought that madVR does do dynamic tone mapping to adjust brightness to the whole image, but I think this only seems to work in SDR. It should be able to do this since it does know peak brightness of each scene. However, for most of the range when output in HDR, brightness seems to be unchanged. Is this due to the static metadata that is sent for HDR? Are our TVs only relying on the HDR nits mastering in the metadata to scale brightness? Maybe if the metadata can be manipulated to send peak brightness of the scene as mastering metadata, it may change the brightness range dynamically. I don't know.

[HDR]

That's not the issue. I'm using NV for HDR output.

LG's active HDR dynamically adjusts the brightness of the entire image per frame. madVR does not. Because of this the madVR image appears too dark on most low/mid lit scenes compared to LG's implementation.

Anyone who has an oled can clearly see the difference between the two.

https://media.flixcar.com/f360cdn/LG_Electronics-2407895202-Calibration_Notes_for_2017_LG_OLED_TVs.pdf

*LG’s ‘Active HDR’ function analyses content on a frame by frame basis in real time, to
determine metadata for the scene. This information is then used to adjust the HDR tone-curve
to match the content, on a frame by frame basis.
Control of the ‘Active HDR’ feature is found in the ‘Dynamic Contrast’ setting in the Expert
Picture Settings menu. In HDR mode, the Dynamic Contrast settings are defined as follows:
•
Off - Active HDR Disabled / Contrast Enhancement Disabled
•
Low - Active HDR Enabled / Contrast Enhancement Disabled
•
Medium - Active HDR Enabled / Contrast Enhancement Low
•
High - Active HDR Enabled / Contrast Enhancement High
The default setting of ‘Low’ is recommended for accurate content reproduction.

I agree, however I can also clearly see the benefit of the pixel shaders in reeling in the highlights into the brightness range of the TV. The dynamic tone mapping on my LG clearly fails to do this accurately enough to recover the details, especially in the extreme regions. I've been testing out a higher peak nit value of 1000 to bring in the highlights more accurately towards something that dynamic tone mapping won't over darken or screw up.
Ya, madVR is clearly better at restoring detail in extremely bright regions than the tv, but only if "highlight recovery" is turned on, and the higher setting the better, (are you insane?) is my preference.

[ryrynz]

It's 'are you nuts!?' considering this is madVR, maybe this should be expected?

I'd like to put forward some new setting names.
None - remove
low - Pretty mad
medium, Right mad
High - Extremely mad
Very high - Super mad
Are you nuts!? - Chris Brown mad.

[j82k]

LG's dynamic tonemapping will literally brighten up any scene that isn't super bright already. I guess they implemented it for those watching in a bright room or for those that always complain about HDR being too dark. Personally I don't like it, it's like compressing the dynamic range of an audio track so that every scene has the same volume. With madVR dark scenes will stay dark unless you use a very low target nit peaks value.
Brighter isn't always better even if a lot of people seem to think that way...

[blaubart]

That's not the issue. I'm using NV for HDR output.

?? Also Windows is using NV (Nvidia) for HDR output. To bypass the GPU you had to stream the video to the TV (or per USB). I do that often to see what Windows/madVR actually are doing wrong.. :)

[huhn]

windows is not using nvidia API to accept an HDR image from software.

we currently have 3 different HDR APIs.
windows own API.
nvidias API
and AMD API.

but you are just making conclusion without even known this.

Hmm...my line of thinking is this: no display is natively BT.2020, even the ones with the widest of gamuts need to remap from native gamut to a stabdard gamut ...even plasmas were not strictly rec.709, they had wider gamuts than rec.709 natively, there is always a 3D LUT or some other processing involved to get the colors in place (especially if a display has user-accessible CMS system) and these things should be optimized to run without hickups in all circumstances...
you can not use an Tvs CMs change red to red -1 and it will create a new 3D LUT. and that'S not the point with bt2020 you send the display a ton of useless data or a lot of data that can be corrected beforehand .sending DCI P3 would be far better for the time been.

[blaubart]

..angry huhn again - do you feel better now? My above conclusions in the end were right. Having wrong black/white clipping is in the end as easy as having a buggy driver version. No theories needed for that.

It accomplishes the same thing that HDR10+ and Dolby Vision does.

If you enjoy watching crushed blacks and a dim picture be my guest.

[nevcairiel]

It accomplishes the same thing that HDR10+ and Dolby Vision does.

Not really, its just "fake".

Actual dynamic HDR has mastering engineers controlling the parameters of every scene, so that intentional brightness differences are fully maintained, which can give a movie much more depth.
Those automatic algorithms have no clue about the creative intent of a movie and they just "unify" everything, which can take away a lot of depth.

For me, its in a similar boat to the extremely cranked up brightness and color vibrance, or those fake HDR encodes you can find online made from consumer SDR sources. It makes for good show floor presentation, but its far from the creative intent of a movie. If you are into that sort of thing, go nuts. But don't claim your subjective preference is the only valid way to watch anything, because thats just silly.

[vanden]

Edit: it's fixed in madVRhdrMeasure10, just wait for the new release. (Although my laptop doesn't have enough juice to use both "compromise tone & gamut mapping ..." unchecked and "highlight recovery" at the same time :) )
Yes it works properly with "madVRhdrMeasure10"

[el Filou]

I am personally suspicious of someone whose account name is 'HDR' and whose very first actions on this forum consist of coming to madVR's thread just after the release of the best HDR processing featureset in a renderer, to say LG's TVs are doing a better job. :rolleyes:

Exactly :)

[zapatista]

a general question for the video experten here:

is it possible with madvr to use the GPU (for ex from a gtx 1060) to play mp4 video files instead of it being processed by the cpu ?

my haswell i7 cpu seems to do most of the work , and i am hoping to offload it to the more modern GPU that might be more efficient (fine for mp4 @ 2k, but the cpu maxes out on 4k mp4 files while the GPU is only @ 10% load). with HEVC files of same resolution, the GPU does most of the work and the cpu stays @ 20 % for ex, this is much more hardware cpu/gpu efficient (i know hevc is a much more efficient file format, but am hoping the gpu can be used more for mp4 decoding now to)

[sneaker_ger]

Madvr doesn't do video decoding by itself, other components need to handle that. Usually, players/decoders that allow HEVC hardware decoding also allow H.264/AVC hardware decoding (H.264/AVC is the most common codec in mp4 files, but there are others). For example LAV Video/MPC-HC can do that.

[kostik]

Anyone else have a pinkish-magentish screen if you choose YCbCr 4:2:0 when watching HDR content (MADVR shows NV HDR...) ?

Working fine with ycbcr 4:2:2/4:4:4 and RGB … only happens with ycbcr 4:2:0 when the screen switches to HDR mode (NV HDR not Windows HDR which works fine)…
