Next thing is rendering via madvr. Create an empty folder called "ShowRenderSteps" in the madvr folder. Activate madVR OSD (ctrl+j), make a screenshot and post it here.
I have reinstalled to the latest madVR and LAV Filters. I have change to default values both softwares and change LAV Video Decoder to D3D11 - Automatic/Native and now I have frame drops only on the launching of movie file and after few seconds there are no more frame drops. When I set LAV Video Decoder other then D3D11 I have frame drops. When I set D3D11 and other then Automatic/Native let say: NVIDIA 940MX or Intel 620 I have also frame drops, so the only one setting works for me Automatic/Native.

I don't know, why automatic exlusive mode is not working and why there is 8bit stated in madVR statistics.

Sincerely

Hi. I have managed to check on a HDR display today, and I can say for certain that this DOES NOT happen.

There IS indeed an issue with the conversion, or setting somewhere, so I am still looking for help with this as my first post says.

Since you are a long time lurker, do you not think more info from your side would help.

Graphics Card/Driver
Version of MadVR, are you using the latest Beta for HDR to SDR as it is still only Beta testing on it at the moment.

Sounds to me like an "overblown reds" if its an ATI card, but since you don't give any info apart from this is broke, please fix it, with no more input from your side,

There a lots of settings in the later Testing builds here, but as I said, they are still testing it, so there may be issues along the way still.

Using a GTX 970 latest non-beta MadVR ( tried beta too ) in conjunction with PotPlayer.

This issue is also present in MPV Player.

Do shaders work with madVR and HDR? They only starts with EVR CP.

Post 208.

You also say another conversion issue when someone showed you a screenshot of the "Bluray Remaster", you are not reading the posts.

To sum up its the UHD, nothing else.

And as far as Official/Beta/Testing for HDR to SDR, it has always been a work in progress.

They work for me on Windows 7 with MPC-HC/BE + madVR or EVR CP.

Daicon said he was on Windows 10 and needed to install DirectX.

What you select and what is actually being used might differ (software fallback). To check see what LAV Video settings of active instance state as "Active Decoder: [...]" and "Active Hardware Accelerator: [...]". In madVR OSD the decoding queue indicates whether video decoding is fast enough (queue always full or nearly full) or not (queue low/empty).

LAV Video Decoder and...

1. No frames dropped.

Hardware Decoder to use: D3D11
Active Decoder: d3d11 native
Active Hardware Accelerator: Intel(R) HD Graphics 620
Hardware Device to use: Automatic (Native)

2. Frames dropped.

Hardware Decoder to use: D3D11
Active Decoder: d3d11 cb direct
Active Hardware Accelerator: Intel(R) HD Graphics 620
Hardware Device to use: Intel(R) HD Graphics 620

3. Frames dropped.

Hardware Decoder to use: D3D11
Active Decoder: avcodec
Active Hardware Accelerator: <none>
Hardware Device to use: NVIDIA GeForce 940MX

...so what we know more now?

Sincerely

The result is as expected: Kaby Lake can decode the video (fast enough) and with native D3D11 there is no bottleneck copying frames from/to RAM. So with 1. any remaining slowdowns should be because of too demanding madVR processing.

Thank you for your fast reply.

So there should be no problem with Intel NUC 8th Generation either? There is Intel Core i5-8259U with Intel Iris Plus Graphics 655.

With DXVA2 Native or D3D11 Native decoding, and low madVR settings, you can play stuff surprisingly well on NUCs. So yeah, it should be mostly fine. Just don't expect too much from madVR, since the GPU is weak.

I would recommend to wait until Q1 of 2020 for Intel's Elkhart Lake with Gen11 Graphics !!!

Yes thank you.
HDR now looks better, but SDR is oversaturated, even with DCI-P3.
And more trouble - the rendering time has increased 2 times (30->60ms) on my Vega8 (Ryzen 3 2200G)

Try setting calibration to BT.2020. Some AMD drivers do strange things to the color space.

This was posted at the DSPlayer forum. I'm not certain if it works or will bring back functioning stereoscopic 3D playback to Nvidia, but it might be worth a try:
