madVR - high quality video renderer (GPU assisted)

[Cowboydude99]

Hi there,
Can someone help me with my profile rules. I cannot seem to get this right...

If (scrWidth = 1920) "1080p"
Else If (scrWidth = 3840) and (fps > 30) "4K_24fps"
Else "4K_60fps"

The 4k 60 profile is never used, it always uses the settings in 4k 24fps. 1080p seems to work just fine.

hi, thank you for your comment.
The conversion from HDR to SDR was not my initiative. I read that some users who own an OLED or LED TV have given up on converting HDR to HDR to switch to converting HDR to SDR.
At the beginning I was very skeptical too like you .. then I made several tests and I had to change my mind.

Hi there. Thanks, but having the same issue. I just copied and pasted what you entered...

It looks like the 1080p is OK and the 4k 24fps is ok.
4k 60 plays the 4k 24fps profile... so line 2 seems to be catching the 4k60 file...?

When setting up MadVR, I set the HDR to passthrough.
HDR profile does show up on my projector.

If I Control+J the video to see the details, it shows up BT.709 (Best Guess). I'm playing 4k UHD files. I believe they're all BT2020.

Is there a setting I need to adjust? I have the PJ showing in MADVR with calibration of BT.2020.

Also HDR shows "Unknown".

NVIDIA control panel shows 8Bit RGB Full

if     (srcHeight < 1081) and (deintFps < 25) "1080p23"
elseif (srcHeight < 2161) and (deintFps < 25) "2160p23"
elseif (srcHeight < 2161) and (deintFps < 61) "2160p59"

This is a very trimmed down version of mine:

if     (srcHeight < 721)  and (deintFps < 25) "720p23"
elseif (srcHeight < 1081) and (deintFps < 25) "1080p23"
elseif (srcHeight < 2161) and (deintFps < 25) "2160p23"
elseif (srcHeight < 721)  and (deintFps < 26) "720p25"
elseif (srcHeight < 1081) and (deintFps < 26) "1080p25"
elseif (srcHeight < 721)  and (deintFps < 31) "720p29"
elseif (srcHeight < 1081) and (deintFps < 31) "1080p29"
elseif (srcHeight < 2161) and (deintFps < 31) "2160p29"
elseif (srcHeight < 721)  and (deintFps < 51) "720p50"
elseif (srcHeight < 1081) and (deintFps < 51) "1080p50"

Hi, i've dabbled with this myself and i'm doing that at the moment for reasons I wont bore you with but my OLED is only 450 nits max so Its barely capable of HDR, I would say if you have a new OLED with 700+ nits you should probably output to HDR but also have a play with tone mapping in madvr to pull out a bit more highlight detail.

Ah, use deintfps instead of fps, like QBhd did above, perhaps also use 26 instead of 30:

If (scrWidth <= 1920) "1080p"
Else If (scrWidth <= 3840) and (deintfps < 26) "4K_24fps"
Else "4K_60fps"

Ah! That did the trick. I ended up using the following:

if (srcHeight <= 1080) and (FPS < 25) "1080_24fps"
elseif (srcHeight <= 2160) and (FPS < 25) "4K_24fps"
elseif (srcHeight <= 2160) and (FPS < 61) "4K_60fps"

Hi,
Here is a screenshot of the issue with BT.709 (Best Guess).

I have an HDR projector (JVC) and the chain is:

Jriver Media Center + MadVR + SVP4 Pro -- Denon AVR -- Projector.

The PJ turns on the HDR profile.

The files are BT.2020 UDH disks.

Any idea what needs to be changed to ensure BT.2020 color and that HDR is actually in use?

Also, NVIDIA Control Panel = RGB 8Bit Full. 422.74 drivers (Win 10). I am able to change it to YCC422 10bit.

Screenshot below shows RGB 8bit, but I can set it to 422/10bit. It will show in the OSD, but it continues to show BT709.

you have ffdshow or something else installed?
else this file claims to be 8 bit nv12 with no meta data.

Ah, noted!

Yes. Ffdshow I believe is installed with SVP4 Pro. It has solved my stuttering issues.

I removed it for testing and now I see BT.2020 listed in the MADVR OSD.
It doesn't seem to want to switch to FSE mode.

I guess I'll reach out to the dev of SVP4 Pro, but something tells me there is no solution...

Would a TV/Projector play the HDR profile if it wasn't getting 10bit HDR?

[huhn]

yes they will play it if they don't get 10 bit i don't even know why you think this is related.

Are you sure changing to native did not change the way HDR is being handled? You do need copy back to be able to run all the HDR tone mapping features so I suspect the improvement came from not being able to run those anymore, rather than an actual performance improvement from running native.

Is this true about needing copy back to use all the tonemapping features? I’m seeing conflicting information on this.

[Asmodian]

It is for v0.92.17 to be at least, I am not sure about the various beta versions.

[SirMaster]

You do not need copyback for any tone-mapping feature on the betas for last year at least. You only need it for black bar detection and BluRay menu support.

It used to be that highlight detail recovery didn't work with native deciding. But it has for awhile now.

Okay thanks, I don’t use black bar detection and I don’t play blue rays with it so I think I’ll use d3d11 native.

[amayra]

can madvr detect what is my display Color Depth ?

[Asmodian]

Yes, it also reports it as part of the first line in the OSD (ctrl-J).

Also, it defaults to "auto" for the display bit depth and will switch to 10 bit output if the display color depth is 10 bit or higher.

[huhn]

on nvidia only.
