madVR - high quality video renderer (GPU assisted)

[tyrindor]

After updating to Windows 10 Fall update, exclusive fullscreen mode no longers works just black video with audio. I am using MPC-BE. Hardware acceleration is set to DXVA2 (copy-back).

Updated both MadVR and MPC-BE with no results.

Try to pass this file through DXVA Checker's playback benchmark and compare different decode methods (software/CUVID/DXVA).

Note: I don't know if it's a must-have for you, but FYI the 1060 can't decode VP9 10-bit (YouTube HDR) in hardware.

Never heard of a DXVA checker. Going to try it.

Does the 1070 have VP9 10bit hardware decoder?

EDIT: Just tested it and I got 42 fps with 98% GPU use and 40% CPU use. Played with 64bit.
So.. why it's stuttering? Maybe because of HDR to SDR conversion?

DOUBLE EDIT: Tried the 32bit playback benhchmark, it was down to 28fps.
So I guess I need 64bit version of MadVR?

No my findings pretty much echo what you describe. I had one bad video where without DRTD it started weakening artifacts around some letters from strength 1 and they were completely gone at strength 4.

However with DRTD on nothing happened with these particular artifacts until strength 11 where obviously the rest of the picture was ruined at that point.

nope I agree, remove it!

Confirmed. MPC BE bug. DsPlayer working just fine

It's not a MPC-BE bug. Internal EVR-CP perfect working in FSE mode.

there is a crash report here

v0.92.7 & v0.92.6 crash

v0.92.5&v0.92.4&v0.92.3 unknow，not test


crash step：
1、play a movie file
2、full screen
3、pause play back（don’t touch anything，just stop）
4、auto close screen（by power management setting）
5、wait 1 minute more
6、open screen（move mouse or touch any keyboard）
7、you can see crash now

other info：
win10 x64 15063、mpc be x64 v1.5.2、lav x64 v0.70.2、16G ram、i7 4760HQ、iris 5200

there is a crash report and settings.bin

i hope this information is useful for bug fix

And then simply activate HDR -> SDR conversion by using pixel shader math in madVR. That way madVR will first convert HDR to SDR, and then send it through the DCI-P3 SDR 3dlut.

Can you hint more about how to combine 3dluts and HDR -> SDR conversion ? Where is the slot to store a 3dlut ?
Right now I only have 2 choices, either to use HDR -> SDR conversion by using pixel shader math OR by using an external 3DLUT, but not combining both of them.

[Asmodian]

The output of the SDR conversion is run through the standard SDR 3DLUT set for your display. Once it is SDR DCI-P3 the normal DCI-P3 3DLUT is appropriate.

no the 1030, 1050/ti and maybe the 1080 ti are supposed to have a vp9 10 bit decoder.

if your gpus is maxed from decoding how should it use madVR?

only depands on your player. but you are pretty much wasting your time hybrid decoding is in general bad but hybrid decoding and madVR is unlikely to work and the higher the bit deep the slower this decoding is getting.

Well, vanilla RCA@1 looks pretty soft with AB25% SSIM2D and I like what AB25% does to SSIM2D.....if refining is no option, could you please lower the actual strength of @1 then? Some videos call for deblocking but because it can't quite differentiate artifacts and details it definitely oversmooths things on non-hopeless footage IME

Drop 12 add a new 1 and shuffle em up xD

You change color in Resolution tab?

Yes for both.

Yeps, full RGB, 8bit is set in Nvidia CP. I suspect the TV FW, since the colors & switching to/from HDR was working fine before.
When i start playing HDR content, it results in purple video, after turning the TV OFF & ON, it displays proper colors & HDR (see attachments).

Actually i didn't change any settings. I 'clicked' through and when comparing with previous settings, the new settings were a lot brighter.

No, the image is cleaner with it off.

Here is what RCA can do at 4 with grain added to a pretty bad source :

I really like the result in motion, no more disturbing artifacts

Hopefully something positive will come out of it.

Cool. Are you planning to sell it for money?
If you're not a plugin for a free and simple image editor would be far more accessible for people like me who only use these casually.

(I mentioned paint.net, but there might be others. Not sure if there's anything is more widespread or appropriate. I'm certainly not familiar with any.)

[Rexian]

I started having this problem a few weeks ago with no change I could point to. Since then I upgraded to the latest versions of pretty much everything -
madVR 0.92.5 then 0.92.7 today
mpc-hc 1.17.11 then 1.17.13 today
Lav 0.70.2
nvidia 287.92 (updated from 285.xx today)

Both mpc-hc and mpc-be work fine in a window (TV recognizes HDR videos) but the screen goes dark as soon as I press alt+enter (audio continues) and then when the picture comes back after few seconds, it crashes.

Here are the settings -
nvidia


LAV


madVR prop


madVR reder


Also tried disabling FSE. Screen doesn't go dark but crashes right away -


Updating to W10 Build 1709 now... anything else should I try? Thanks for any pointer.

[fedpul]

Hi, quick question. Can I create profiles based on bitrate? Thanks in advance.

Quick Answer: No.

[Anima123]

Madshi,

As we know, there are much more blocky when video is in motion than static views, especially if the video stream is poorly encoded, like constant bitrate for both scenes. Is it possible for some kind of adaptive strength or algorithm been applied to RCA in the future?

I had the same problem. It appeared that the D3D11 setting in madvr (rendering->general settings->Use Direct 3D 11...) was disabled. I enabled it and restarted MPC BE and problem was solved.
