madVR - high quality video renderer (GPU assisted)

[Asmodian]

I have also noticed better performance with small buffers in madVR, I keep the "number of frames presented in advance" at 3 or 4 and GPU buffers at 4 or 6. I noticed this when I switched to Windows 10 but it doesn't seem to be a universal observation (there don't seem to be any universal observations).

It is a good idea to put "strength during fade in/out" on the same level as "default debanding strength" for reduce banding artifacts (if it is enabled) or keep the trade quality for performance option "don't rerender frames when fade in/out is detected" enabled (recommended anyway, in my opinion).

Thanks for advices guys!

Increased buffer size in LAV splitter (up to 512Mb) and tried increasing/decreasing buffer/queue size in madVR and somehow it did increase overall stability but unfortunately didn't fix the issue completely.

Hi to everyone!

I'm trying to use some upscale settings for improving image quality using MPC HC and madvr.

My target is upscale from 720p and 1080p to 2160p.

I used 720p anime and 1080 bluray movie at medium settings and high profile to upscale 2160p but I can't see any changes for image compared to the original.I have a lot of drops frames seems to upscale algoritms working but when i pause and save image as png/bitmap 100% quality (alt+i) at from MPC I don't see any changes.

The screenshots result are identical wich is weird :
source 1920 x 804 (4.2mb) and after uscpale 1920 x 804 (4.2mb);

-1280 x 720 1.88mb (original) and 1280 x 720 1.95mb upscaled.

Another result for 720 source: (print screen)
-3840 x 2160 (720p source) 23.7mb bmp - 3840 x 2160 (720p source) 23.7mb bmp (after upscale)

My setup: Win 10 X64 with last update, latest MPC and madvr;
Intel Skylake i5 6500, 8gb ram, GTX 1050ti 4gb, ssd Samsung 256gb, Samsung TV 55ju7500 2160p resolution 60hz.

regarding the HDR toggle problem with latests AMD drivers, AMD have contacted me and I have provided them my DXDIAG and full Belarc report so it looks like thy are taking it seriously.

I got the same requests, but i have a different feeling.

in the mail they sent me they are asking about app freezing (i never talk about freezing) and performance issue (never wrote about performance)
they ask me to demostrate with a video the issue.
Also seems it's not clear that the issue is happening from many versions of the driver.

I'm not sure that i want to do their job, debugging, starting from update my system to a driver that I already know is broken to send them what ? something that they can reproduce easly (they are amd) with the information that i've sent to them in terms of repro steps and software e Hw versions.

AMD is keeping to piss me off (sorry to be rude), starting from couple of years ago when they removed all video configurations in the drivers , they made me waste a lot of time to provide them all infomations requested and in the end all those useful controls never went back they closed the issue with no issue.

this is my opinion, if you have time to break you pc with broken driver and send them all the infos i say a big thank you to you , but i'm not sure that i will do the same.

Use an image hosting service like imgur, and post the links to your images.

same answer you are still comparing the same image with each other.

I wanna ask why I send original dolby vision HDR mediadata with madVR to my TV set,my tv set doesn't decode the original dolby vision HDR? I'm very confient that there are hardware decoder chipsets on my TV set because i play some demonstration films from dolby co. website with my tv set.Doesn't madVR support to send original dolby vision HDR content to the display?Just support to send HDR10 content to the display?

[Asmodian]

Dolby Vision decoding is not supported by anything free, as far as I can tell.

Playing back Dolby Vision is not simply sending different metadata, it is much more complex and no one has released the specs so no one knows how to do it.

Ah,i get it.Thank you,master,very much.

I think I saw the problem: every time when I take a SS the size depends for screen ratio from MPC. If I take a SS (alt+i) from full screen, all of them will be at same size and resolution: 3840 x 2160 ( my screen resolution).
If a take from half size player the resoltuion will be half of 2160p.
How can I obtain a SS with original video resolution?
How can I "force" to upscale to 2160? except madvr upscale settings.

you are probably right, however this might be a bigger deal than we think as everything is going HDR at the moment so they may want to put some resources into this if netflix isnt work properly either.

I'm hopeful

I agree even I'm still negative, in case I find some spare time to make all things requested, I will send to them.

Have you tried the various settings under rendering -> screenshots in madVR's options?

[SirSwede]

Can someone please recommend settings for:

• Chroma upscaling
• Image upscaling
• Dithering

When playing a 1080p, 50 fps, video to a 1080p, 50 Hz, screen with a GT740 GDDR5 card.

It won't do NGU unfortunately. Can it if I do some trade quality for performance?

[waldnebel]

Do I have to activate or to deactivate that "HDR and WCG" option in the display settings of Windows 10 if madvr is used as a video renderer?

[Asmodian]

No, leave Window's HDR option off when using madVR.

Didn't we already give you a bunch of recommendations?

Jinc for everything since you cannot run NGU. SBR 100 for chroma upscaling is also an option, compare to Jinc and pick the one you like more.

Ordered Dithering.

Trade quality for performance options are not going to help you run NGU.

Yeah, but 50 fps wouldn't accept those recommendations unfortunately.

[Asmodian]

Ah I see, yes the GT740 is a very weak card. Hmm.. you might need to stick to the defaults for 50 fps, maybe try Spline or Lanczos 3 for chroma and image upscaling.
