I have the BOXNUC8i5BEK NUC, and I found the iGPU totally unsatisfactory for madVR use. My 4K TV actually does a better job with HDR10 content than the current official build of madVR, and it supports Dolby Vision. Of course, madVR can't be beat for upscaling everything else, so I ended up buying an eGPU enclosure with a Thunderbolt 3 interface (Razer Core X) and installed the GTX 1080 I had in my desktop. I spent more money than I intended, but now I have the best of both worlds in my living room.

Are you talking about the media front-end used or the media player?

The chroma information isn't presented correctly. D3D11 Native is a better choice for that reason.

Hi guys, been lurking for years but I finally have a question to ask so I decided on signing up.
I have been tinkering with MadVR's HDR to SDR for a few days now, and for the most part everything is looking great, but I have noticed a few little issues that I would like to fix if at all possible. A couple of examples; Evil Dead 2. The reds are bleeding into the white area of Ash's teeth and eyeball. Die Hard. The reds in this scene really overblown compared to most other areas in the film. There is patchiness on the right side of Holly's face and neck. This isn't just limited to my PotPlayer/MadVR setup. It also happens with the all-in-one MPV Player. Is this an fixable on my end, or am I expecting too much from HDR to SDR conversion. |

The first screenshot is exactly the same in the SDR version. This kind of thing should be checked before blaming the conversion to SDR. As for the problems of oversaturation, there's not much you can do ATM apart from adjusting the color settings on your TV.

Based on what reference are we to say it's Over-saturated ?

Hi everybody,
after I finally got some UHD HDR content (that I cannot play because no HDR displays) I somehow got into experimenting instead of just using x265 / madVR and tried to implement mastering display coloring volume metadata into x264 (since the H.264 spec supports it). Even with some help from x264dev on freenode I wasn't able since I can't do C. In the end someone else wrote a patch with the missing bits. x264 can do HDR now ... woohoo Sadly madVR doesn't enable tonemapping as it does for x264 HDR content. I guess it's just not enabled for h264 content? |

i'm not a developer for this but the meta data has to reach madVR.
if the source filter needs to repack the meta data for directshow so the renderer can see it you will need the patch. lavfilter may not even look for the meta data for obvious reasons. for VP9 a change in lavfilter was needed to get the meta data to madVR. madVR on the other side didn't care and just worked as soon as it got the meta data. just wait for nev on this he should know. no need to speculate more on this. |

Sorry, absolutely. Here it is https://pastebin.com/nRcBrM3M Here's the output of h264_parse mpeg4ip version 1.5.0.1 of a file (HEVC HDR to x264 HDR) encoded with a patched x264 https://pastebin.com/cKtUbKUm Last edited by an3k; 13th June 2019 at 06:26. |

Dear Friends
I own Lenovo Ideapad 320 i3-7100u with iGPU Intel 620 and GPU GeForce 940MX. I have tried to watch .mkv remux of Gladiator 2160p 23.976 HDR 10bit, but it's not smooth. Rendering is below 41.71ms, but there are lots of dropped frames. Notebook is conntected to my monitor LG 27UK600-W 4K HDR via HDMI cables via Onkyo TX-NR686 (HDMI 2.0b HDCP 2.2). MPC-HC 1.8.6, madVR 0.92.17, LAV Filters 0.74.1 NVIDIA Control Panel set to maximum performance of 940MX, Windows 10 1809 also 940MX. LAV Filters - Video Decoder - D3D11 and 940MX This notebook hardware is to weak to have no frame drops or I am doing something wrong? Thank you in advance for your help and replies. Sincerely |

940MX is used for decoding (see settings window of active LAV Video instance)? According to Wikipedia 940MX is only VP6/Feature Set E, i.e. no good HEVC 10 bit decoding. Or are there more variants? i3-7100u (Kaby Lake) can do it, though.
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. |
