Sorry if this has been covered before but the thread is huuge, the search found nothing.

I'm using HDR->SDR conversion via MadVR to a measured 180 nit monitor with cca 2.2 gamma...I have measured the post-MadVR gamma curve for it with a colorimeter, with "compress highlights" turned on...comparing it to the BT2084 curve, I find that the rolloff starts way too early, as low as 30% (10 nits) input while it should start at around 50% (or around 100 nits) since that's what color grading aims at as diffuse white. I know 200 nits peak brightness of an average monitor is not exactly HDR, but what I propose, there would still be 100 nits to do the rolloff and achieve more of the HDR effect...just a note: changing current options except turning off "compress highlights" made no difference...

I'd like to encourage the Great Madshi to look into this and hopefully adapt the behaviour of the conversion. Thanks.

be awaree that windows 10 pretty much hates FSE and it has changed alot in term of FSE and depending on the windows 10 version you are using you may have more or less problems.
MPC-HC clearly is crashing when:

"use Direct3D 11 for presentation..." is enabled
or when "automatic fullscreen exclusive mode" is enabled
in case of any source I have but "frame-packed" 3D sources.

and of course frame-packed 3D rendering is only working as it expected when:

"use Direct3D 11 for presentation..."is enabled
and when "automatic fullscreen exclusive mode" is enabled, too.

So for a stable workflow I need to create separate profile for 3D sources and everything else currently. I have to give up with 10-bit processing as well due to lack of feature Direct3D 11.

Does anyone have some solution? Going back to a previous Nvidia driver would help? Or should I wait for a win10 repair/new driver from Nvidia?

madshi, there's a few UHD titles that madvr doesn't correctly recognize the HDR properties. One such title is Planet Earth II UHD Blu-ray. It says "HDR, unknown properties." Another title I encountered this with is Terminator 2: Judgment Day. Maybe it's just a cosmetic thing, but it does correctly measure the peak values.

There is no HDR metadata for these titles. They have all fields set to zero. Nothing to do with MadVR, which is correctly reporting the absence of information.

Same for Life of Pi and the UK version of Dunkirk.

Good catch. Didn't notice that at first.

I don't know about "quickly", but you can use something like AutoHotkey to issue the "next frame" key in the media player followed by the screenshot key. Decent players auto-increment the screenshot filename, and so long as you add enough delay between frames (or pixel peak the timeline/framecounter for perfect control) it should work fine for small clips.

You may need to check MadVRs screenshot options to make sure it's outputting the expected results (I believe there are options to use pre/post resize for example).

In case of "frame-packed" 3D source, is it the correct behaviour of madVR not to double the source to 4K, even though the display is 4K with the refresh rates and resolution and a "3D" profile's doubling algorithm set properly? I expected 2 pcs of 4K image being sent to the display.

Any help would be appreciated.

3D is capped at 1080p that's the maximum HDMI supports there is no UHD 3D spec.

HDR10 conundrum

A happy New Year to everyone here and a conundrum regarding HDR10 for the new year…:
  • I have a couple of HDR10 demos, which let my Sony TV switch automatically into HDR mode using Zoom Player and madVR
  • I have a couple of supposedly HDR movies, which DON’T let my Sony TV switch automatically into HDR mode using Zoom Player and madVR, but when playing them through the TV built-in video app, the TV switches automatically into HDR mode

My setup:
Windows 10 Enterprise 1709 64bit
Zoom Player 14
madVR v0.92.10 -> set to 10bit and 0-255 and HDR metadata passthrough
Nvidia GTX 980 385.69 -> set to 12bit and RGB Full
Sony XD9305 TV (HDR ready)

Test scenario A:
Playing HDR10 demos (Exodus trailer and LG Colors of Journey demo) through madVR -> TV switches to HDR mode -> ok
Playing HDR10 demos (Exodus trailer and LG Colors of Journey demo) through TV built-in video app -> TV switches to HDR mode -> ok
CTRL+J shows the following information for both files:
D3D11 10bit windowed
Matrix/Primaries BT.2020
P010 10bit 4:2:0
Test scenario B:
Playing HDR10 movies (HDR10 according to their file names) through madVR -> TV doesn’t switch to HDR mode -> not ok
Playing HDR10 movies (HDR10 according to their file names) through TV built-in video app -> TV switches to HDR mode -> ok
CTRL+J shows the following information for both files:
D3D11 10bit windowed
Matrix/Primaries BT.709
YV12 8bit 4:2:0
The movies first look washed out when playing through madVR. But when switching the TV manually to HDR, the colours seem to be fine (they look the same as when playing throug the built-in video app).

Now to the conundrum (I hope you are still with me…):
  • According to their file names, the movies are supposed to be in 4K HDR10.
  • The movies are from different release groups, but they behave all the same.
  • When playing them through the TV built-in video app, the TV automatically switches into HDR mode.

Could it be that madVR somehow misinterprets the movies’ video data? Is there any other explanation for this behaviour? How can I tell whether the movie files are really HDR 10bit?

@Goeggel: you could post here the report generated from running your trouble files through Mediainfo software...we need to see what metadata are there in the file in order to help...just please omit the title of the movie from the report

@goeggel: all seems correct...except I've never seen a feature film encoded with ATEME Titan KFE

@mytbyte: As the metadata seems ok, why does madVR show "Matrix/Primaries BT.709 / YV12 8bit 4:2:0" for this movie and seemingly not passthrough the HDR info to the TV? Does madVR do SDR conversion in this case?

The Sony TV video app seems to be able to read the metadata correctly as it automatically switches to HDR.

Thanks for the quick replies by the way!

Dolby Vision requires A LOT more than a "passthrough". Please, try keep these reminders down to once every half a year, at most.

When MadVR does the HDR->SDR conversion it still reports what metadata say in the file...next to matrix BT.709 and primaries BT.709, does it say "(says upstream)" or "(best guess)"?
