madVR - high quality video renderer (GPU assisted)

[Dreamland]

freeze videos (all formats) and player when this is in pause and after, move the seekbar when using D3D11.Works perfectly with native / copy-back

MadVR 0.92.3
LavFilters 0.70.2.74
MPC-BE x64 v 1.5.1 built 2939
Graphic Card R9380
Windows 10 CU X64

Is the display native bit depth set to 10 or more so that you display HDR10 properly at less than 50/60p?
Is MadVR HDR set to passthrough and sending metadata?

It might be display specific otherwise, but still it's only with MadVR.

Also if I launch Teamviewer from another PC, the HTPC output seems fine (no magenta), so the internal composition is not corrupted, it's the GPU output that is wrong at 4K60p RGB 8bits (only).

d3d11 is not enabled in the 1080p profile.

Yes, madVR is set to passthrough and sending metadata. My TV switches to HDR10 mode and everything looks correct. My GPU is outputting 4K60p 8-bit RGB full but the bit depth field is blank because I have 12-bit RGB enabled at lower refresh rates.

Your TV may be assuming a higher bit depth when in HDR mode but is only receiving 8-bit so looks really weird. I had a similar issue when I was able to force Mass Effect Andromeda to enable Dolby Vision while only outputting 8-bit RGB. My TV is fine with 8-bit input for HDR10 but not Dolby Vision.

In all your other working tests with 4K60p does your display ever enable its HDR mode?

As I said, my projector displays 4K60p HDR 8bits fine with the UB900. There is nothing wrong with the projector. This problem only occurs with MadVR.

As I also said, I switch to HDR manually on the display (I disable the manufacturer's mode because it's poor and I apply my own BT2020/ST2084 calibration), so it's not "expecting" anything. As far as it's concerned, it's receiving SDR. And this works fine with everything except 4K60p 8bits from MadVR.

I have tried to force the GPU to 8bits as I also reported, so that the bit depth isn't blank, and that doesn't make any difference. It is definitely 8bits that comes out in both cases, and the display interprets it as 8bits.

The issue occurs when MadVR is passing through HDR, but the display doesn't know/care whether it's SDR or HDR. There is no metadata sent to the display anyway, so that it doesn't switch to HDR automatically and applies its buggy implementation.

So we can safely take the display's HDR out of the equation.

I think MadVR does something in that case that corrupts the picture. It's not an SDR/HDR, full/limited, RGB/YCC, or a wrong calibration issue. It's a completely corrupted picture over the whole desktop, not only the player's window (the two only colors are magenta and black).

I wish madVR wouldn't hang every program I use it with. But that's too much to wish for.

Both ProgDVB and Potplayer hang regularly.

Have you tried MPC-BE? I use the x64 version for LAV/MPC-BE/MadVR and it NEVER hangs.

Is it good to use anti-bloating filter (100%) on image downscaling?

Again, it's not the display, HDR works fine in all modes at all refresh rates with the UB900, so it's not the display or the AVR or anything in between.

However it's not MadVR, I tried to switch HDR on manually in the Win10 display setting and I have the same issue.

So I guess it must be an nVidia driver issue. Which driver version are you using? I reverted to .28 as .41 had issues with 12bits in custom modes, maybe that's the difference. Also what's your OS?

[Manni]

Re above, I tried 385.69 released today, it doesn't make any difference re the 4K60p8bits issue and 12bits is still not selectable for custom modes, so I'm reverting back to 385.28

I have enabled it, but when the movie starts at 1080p .D3D11 disables itself, why?

[nevcairiel]

Including "rendering -> general settings" in profiles is really not recommended, as it can result in odd behavior all around.

[huhn]

and it is not check in rendering for 1080p

I am using 385.41 and Windows 10 1703, 15063.608.

You are sure the UB900 can output 4k60 8-bit RGB with HDR signals? The manual talks about them separately all the time, e.g. "4K/60p (4:4:4) and HDR signals that meet Ultra HD Blu-ray standards". It would surprise me, I expected it to use >8-bit for HDR content (switching to 4:2:2 to enable 60p at >8-bit). It would be great news though, I was worried Dolby Vision on my TV wouldn't work correctly if given 8-bit 4K60p but if it is a GPU driver issue instead there is still hope.

I'm trying to let madvr measure video playback. But it is still displaying "not measured yet" in this video mode. I followed the four steps. What am I doing wrong?

Thanks for the OS and driver version, we have the same Windows build.
I don't think .41 will be any different to .69 or .28 regarding this so I'm staying with .28.

I am 100% sure that the UB900 can display HDR signals in 4K60p RGB 8bits, I just double checked with Billy Lynn (all confirmed with the Vertex).

If you set the UB900 to RGB, it has to go to 8bits at 4K60p because it can't use 4:2:2 (RGB is always 4:4:4).

I normally use YCB 4:4:4 12bits because then the UB900 switches automatically to 4:2:2 and keeps 12bits at 60p, which is preferable (no banding).

So it's 100% an OS/GPU issue, it's not the display or the AVR or anything in between.

However as it's not a MadVR issue I'll stop posting about it so as not to clutter the thread, feel free to PM me if you'd like to discuss this further.

It would be great if madvr had a setting to "let madvr decide" for Chroma upscaling, if you happen to play a file and it begins dropping frames or losing sync, to lower the setting until it stops. Not very useful for me, but I can't use certain settings with 4K files like NGU Very High.

[dvd1]

it is now active



starting a 1080p disables D3D11 and the 1080p always starts in D3D9

[Asmodian]

Re-create all your profiles without "general settings" in them.

[dvd1]

done but now it all goes to D3D9
did I do something wrong?
