madVR - high quality video renderer (GPU assisted)

[ryrynz]

Just depends on what sharpening you want at the end of the day. Fire up your favorite content and just watch for comparison. You should be able to determine a preference.

I think the benefit is from doing the sharpening at a the higher resolution. SSIM 2D is sharper than SSIM 1D but using bicubic downscaling is probably better than running the sharpening at the native resolution, assuming you do like the sharpening done at higher resolutions. It can look more natural after downscaling but it also ends up being not as strong.

If you don't want to sharpen at the doubled resolution it is pointless to double and then do a 50% downscale anyway.

SSIM 2D is more demanding than SSIM 1D...Can't use it with my 1050 Ti.

you can just go into the nvidia control panel and test what you could do at 1440p by activating DSR x1.5 and setting the windows desktop to ~1440p. not 100 % accurate but close enough if you are careful.

this is obviously bad for image quality but that's not the point here.

I managed to get FSE working without any dropped frames of glitches by disabling v-sync in Madvr and enabling g-sync and v-sync in Nvidia control panel.

Upscaling 1080p....
Using NGU Standard.
Luma doubling is "medium"
Activate doubling is "always"

Someone help me... Luma is the actual grey scale image...? The resolution?
Because my 1080p video is still outputting at 1080p....
Shoukd it not be 2160p with doubling?

[WuNgUn]

Or maybe it isn't...?
Scale 0,0,1920,1080 - 0,0,3840,2160

Small question, how do save your Madvr settings? Is it enough saving the registry at "Computer\HKEY_CURRENT_USER\Software\madshi"?

[ryrynz]

AFAIA absolutely everything that's saved in the settings.bin (if madVR has write permission to it's own directory) is also saved under that location in the registry. I like to have the bin file as well and keep that backed up.
You can export the madVR registry location you specified or you can allow write access to madVR's installed folder and have madVR create the settings.bin which you can then copy.

[mambans]

@ryrynz
Ah oke, I'll also keep both settings.bin and the registry backup.
Thanks for the help.

Hope someone can help with display modes. I currently have madvr display modes set as 2160p23, 2160p24, 2160p25, 2160p29, 2160p30, 2160p50, 2160p59, 2160p60. but still dont get smooth playback changed all the motion controls on tv but cant it perfect. Also tried the smooth motion options in madvr. My question is, is all content tv shows movies in 23/24hz? anything i watch is shown as 24p on my tv. The resolution changes but the frames per second always stays at 24p. Samsung qled Q9fn with gtx1080 i7 7700k. rendering settings under 35ms

[Klaus1189]

2160p23, 2160p24, 2160p50, 2160p59, 2160p60 is enough and better, because 25 fps content can be interlaced and by using 25 Hz mode you drop the advantage of motion resolution of 50 Hz of 25fps interlaced content, same for 29/30 and 59/60.

[Klaus1189]

And you must decide between the two things:
A) You use refresh rate change with 2160p23, 2160p24, 2160p50, 2160p59, 2160p60
OR
B) You enable smooth motion of madvr and stick with 60 Hz

Try both and stay what you like best, and of course diable all smooth motion interpolation crap of your TV, regardless of the manufacturer.

[Morgin187]

Thanx for your reply and help. I'll try using those to see if it makes a difference. Do i need to include other resolutions or do they get included automatically?

[Klaus1189]

You should only use 3840x2160, because then you let madVR do the scaling and you can take whatever scaling method you like and what your GPU can handle. Other refresh rates are not needed.

By the way, one of my TVs is also a Q9FN with thank god still 1270, do not upgrade your firmware to 1290, disable automatic firmware update now, there is an issue, I contacted Samsung already and they made screensots via Remote control and the Developers get the info. A smaller Samsung of me has already the issue, because it made an autoupdate to 1290 and I recognized the issue. In the meantime just stay with the firmware you have and wait for a fix.

[Morgin187]

thanx but too late it automatically updated. i read somewhere else it makes local dimming better. what is the issue your having?

[Klaus1189]

It only affects pc mode, which you must select of Samsung TVs to get 4:4:4/RGB color shown on the screen, 60 Hz is fine, but when using for example 50 Hz mode then the picture is cut off around (Overscan) and you can not change it in PC mode anymore.
To see the issue, you must set the TV to pc mode first then turn it off and after restart the error uccurs, I called Samsung and talked to them about 45 minutes with a very qualified person and I am pretty sure it will get fixed soon. I couldn't believe not a single one reported that to them, so it took quite long. But really nice that they can go on remote to your TV when there is an issue and take screenshots with OSD info of the TV and so on.

[Morgin187]

Buddy your the exact person i need for more info. Im loving the tv and using pc only for gaming and movies/tv shows just trying to get the most out of it. So i use PC mode with rgb full 8bit to get full chroma or 4:4:4. also hdmi level normal or low with one of these settings. With PC mode im losing settings (greyed out) and can only select dynamic or standard. for e.g i like to up the colour a little for more vibrance i'm not able to get it calibrated professionally

[Klaus1189]

I think I don't understand what exactly you want to accomplish, but the "make the image better" crap like motion stuff is already mostly off and you can adjust in advanced options in picture menu some stuff if needed for further stuff. I must admit I don't know how the english menu entries in called, since I am in Germany.

I just hope that users get that there is not a ultimate TV, just look at LG OLEDs and also some SONY OLEDS, they have bad 24p stutter compared to other TVs:

hi,
i found reproducible setup - and postet it in a new thread.

i have a problem with my video-player,
when playing video from resume position i get (black screen).
some resume positions work, some not.
in attachment i have a log for resume pos 00:01:04 which works, and 00:01:07 not working.

debugger reports, a lot of:
Microsoft C++ exception: _com_error at memory location 0x1ACDBA5C.

in madvrlog i can see: copying back buffer failed (new mode)
and log file gets realy huge.
