madVR - high quality video renderer (GPU assisted)

[Blackwalker]

i'd like to thx el Filou and who give me some tips!
Now it's not perfect, but now i can play without shuttering hdr 4k movie!

I have to test more and more for better result but i wanna say thx!

reducing decode CPU and GPU at 4 (both) helped and set also bilinear and dvxa everywhere in madvr settings helped too.

Continue with testing!

The 550 is like the 450. The 550 is more suitable for overclocking. Try to overclock the 550.

BTW 480 is like the 580. The 580 is just a little bit faster and lesser heat production than the 480.

The 480 is now faster than when it hit the market. Thanks to the driver improvements. This applies to games, not to MadVR.

I thought that LAV supports deinterlacing.

Have you checked Kodi dsplayer 17.4?

With games it is not so terrible.


yep, i'm already using dx11 for lav and madvr. Weak performance is with PAL broadcast 1080i e 578p 50hz, honestly about movies I don't see any big difference using DXVA upscaling or NGU or whaterver watching BD disks.
Anyway i'm going to try the other proposed tweaks.

DXVA is hardware acceleration while madvr work is mostly done by gpu shaders. A Rx 460 has only 896 shaders.
In comparison, the much older r9 290x that I have has 2816.

A video content playing back at 50fps on a 50hz screen has a maximum limit of 20ms to render before frames are dropped.
What is your rendering stats, when you fully switch to using madvr, for full-hd to 4k 50hz upscaling?

ngu is at best 30/40

I got the 550 as I worked out my always on PC bill was about £800 a year to run, trying to get my idle power consumption down so I dont really want to overclock.

Ultimately changing to the 550 was a mistake.

changing from PC levels to Tv makes an image less bright and it losses a lot of contrast compared to the PC level screen.

so first of all you should make sure the levels are correctly setup for your screen.
you can start here: http://www.avsforum.com/forum/139-di...libration.html
the black clipping file is all you need. 16 has to be black if anything below 16 is visible you are most likely running TV level where it should be Pc levels.

a file can be full range and that no problem as long as the file is correctly created with a full range flag if not it can only manuelly be fixed and the file could be considered broken.

Messing around for 2 hours again.
Cant get it to work correctly

Thats what it looks like:

Full range (0-255)

HD ok:



HDR to dark/details missing:




Limited (16-236)

HDR ok:



HD to bright/to much contrast/grey vail:





How can i fix this?

@madshi

So it seems to me that the "3D" test doesn't actually work. Can anybody confirm that? madVR does show "3D" in the Ctrl+J OSD, right?

Ctrl+J OSD when playing 3D.ISO MVC content as follows:

I hate mosquito noise, which is grew up due to UI changes in 7.00 Dota. It's great that thanks to madVR, now there is a choice between sharpness and a less dirty picture.

RCA is less effective on blocking artifacts than on mosquito noise etc., so a touch of RRN is useful for sources with blocking.
I assume that dedicated deblocking algorithm would be better and could preserve some more detail, but 1-4 drtd / 5-12 or 1-5 rrtd / 6-12 is good compromise for RCA in my opinion.

@Madshi @Nevcairiel

Did you get a chance to look at the DVD playback issue with the Klute sample?

As far as I can see the issue is still there with the latest LAV+MadVR.

Thanks!

Disable XySubfilter. Its conflicting with all the things.

I tried the internal subtitles or no subtitles, that doesn't seem to make any difference here, the problem is still there (using MPC-BE and restarting the player after each change).

Also why would there be a problem only with a few titles?

[nevcairiel]

Who knows. Plays perfectly for me in MPC-HC without XySubfilter installed (uninstalling may be required to ensure its not interfering, just unselecting it for subs isn't enough). madshi could reproduce troubles with XySubfilter as it tried to force itself in there, went away without it.

Sorry but even uninstalling yxsubfilter doesn't change anything.

It doesn't make sense anyway, because whether xysubfilter is installed or not, if I select EVR-CP as the renderer in MPC-BE the problem goes away and the menus are absolutely fine, so that suggests a MadVR issue (or a MadVR configuration issue).

Installing/uninstalling xysubfilter = no difference
Selecting MadVR / EVR-CP = issue / no issue

[mclingo]

trying to understand why my CPU is getting hammered by MADVR, thought the processing happened on the GPU.

CPU us halved why I choose DXVA NATIVE instead of COPYBACK, is this because this is essentially turning the MADVR scaling tweaks as COPYBACK is required?

EVR-CP doesn't support the special XySubfilter interface, so that comparison is quite mood, since it doesn't enter the picture anyway.

Anyway, it plays perfectly for me, and XySubfilter was never installed on my system. madshi could only reproduce it with XySubfilter installed, once he removed it, it was fine. So either you didn't really remove it, or your setup is screwed up even further then that.

it also happended when I switch my desktop from 1080p to 2160p manually so it may in fact be a windows 10 or ATI problem, I might roll back some GFX drivers this weekend.

if this happen without madVR i don't see a reason why this is an issue with madVR.

i told you that before and it is confirmed by other user.

so it is not an mem issue.

sorry i don't understand what do you mean

it means debanding is supposed to be "free" maybe ~2 ms.

DXVA upscaling is doing his job perfectly (5 ms) , I'm not interested in crappy low low res videos to upscale,I'm curious and i want just to try something different from DXVA, but seems pretty strange (for me that i don't know anything about GPu code developing ) that it is so awful even with simple upscaling algoritms or processing filters. With games it is not so terrible.

5 ms for DXVA scaling ok there has to be something totally wrong.

can you create a folder in the madVR folder called showrendersteps and make me a screen of the OSD.

do you have a sample. and what level setting is correct the test?

it supports software deinterlancing which is not cheap at 1080p and stops you from using madVR IVTC so it is not an ideal solution.

Still the case with latest drivers? I have an RX560 4Gb here, scaling DVD NGU 4x (Med)/SSIM LL Down (NGU AA Chroma) with RCA 1/Deband Low to 1080P, with headroom. Is this a reasonable test or would 4K be the real test? I don't have 4K screen yet to test with.

[huhn]

you can test it by supersampling 1080p23.
an 960 takes 26-28 ms for NGU sharp high with chroma set to high (NGU low). shown with ShowRenderSteps.

maybe it is limited by the comparable slow pixel fill rate of polaris. fp16 texel rates are slow on polaris too maybe this counts for int16 too.
it has to be something computer games clearly don't care about.
