HDR-to-SDR conversion doesn't work with DmitriRender [DmitriRender bug]

[Toff-kun]

Enabling DmitriRender makes MPCVR's HDR-to-SDR conversion stop working for some reason.

Is it possible to make it compatible somehow? MadVR doesn't have this issue, so I assume it is MPCVR-related.

Your DmitriRender corrupts the properties of the video frame. See Matrix, Primaries, Functions.

Why doesn't it break HDR-to-SDR on MadVR then?

I don't know. Perhaps madVR is doing something to bypass DmitriRender's incorrect behavior. But this is a wrong position that encourages others to do wrong things. We won't do that.

Forgive me if my question sounds ignorant, but could it be that MPCVR simply doesn't have any profile for the "D3D11_P010" input format and defaults to the generic SDR processing as a result? Maybe all that's needed is to apply the same profile / processing to D3D11_P010 as to the regular P010?

You are not right. Open HEVC 10-bit with hardware decoding D3D11 (native) and you will see D3D11_P010.
