I want to leave news here, I have just discovered that reclock has gone open source!!! Now we can hope for a 64 bits version.
There is just a new verison. 1.9.0.0 I got excited when I read a thread that said ReClock GPL'ed Sources but then I realized it was dated at 2010. Last edited by fedpul; 9th November 2016 at 13:31. Reason: I was wrong :( |

I think NG1 is an image doubling algorithm, not a chroma upscaler. IIRC Shiandow was talking about a new experimental chroma upscaler a few pages ago though.

Yes, but an algorithm that can be used for image doubling wouldn't be able to use bilateral or reconstruction type methods. A version specialized for chroma upscaling might, but not the version showed off by madshi.

Hi there,
right now a little off topic from madshis new algo, but here's a little update on my automatic screen masking topic. Madvr is abolute mad awesome! Quite everything I need is already there and right before my eyes. You can easily use profile scripts to detect AR and switch profiles accordingly. There is an option "command line to execute when this profile is activated". Unfortunately there seems to be an issue with this option. I couldn't get a simple command to be executed (e. g. curl command for http get). I also found an old bug ticket: http://bugs.madshi.net/view.php?id=210 which hasn't been resolved. If anyone has experienced the same, do you have a workaround? @madshi: It would be really awesome if you could have a look into this issue. greeting, Stefan |

Youtube now supposedly support HDR and this video is supposed to be HDR https://www.youtube.com/watch?v=tO01J-M3g0U
I downloaded the 1440p and 4k versions and run it with madvr but the video is not detected as HDR. Is the video not truly HDR or does youtube not provide the HDR video if you have an SDR screen? |

Latest MPC-BE supports Youtube-HDR with madVR so I assume it is your player (MPC-HC/LAV?) that doesn't yet support passing the metadata to madVR. Also make sure you are actually downloading the HDR streams.

LAV will learn to read that metadata soon, maybe on the weekend. But it works differently to typical HEVC HDR10 metadata, hence why it doesn't work out-of-the-box.

For HDR upload to youtube you need as bare minimum- Rec.2020 flagging, but ideally use mkvmerge to add all detailed HDR metadata on container level and if you want to make it perfect you can also provide LUT for SDR version:

@fhoech
The metadata is in the webm container for both of those videos but your player might not yet be suited to make use of it (as discussed above). You can use youtube-dl to download the HDR versions ("vp9.2" streams) and mkvinfo to confirm the HDR metadata is present. It's not a madVR issue. |

madshi
I have seen your post http://forum.doom9.org/showthread.ph...10#post1785510 and remembered one simple question I wanted to ask you (I asked many people before - all answered: I don't know) about your great renderer (imho best for 23,976Hz films - never drop frames when set 47,952Hz - and in WinXP too): is there in settings of MadVR easy way to do the picture some less saturated (as EVR or even VMR7w shows)? |

madVR settings->devices->[your display]->color & gamma->saturation
(Not that I think madvr saturation is different from EVR. Both should be neutral by default. You don't have any GPU driver "video enhancements" activated, do you?) Last edited by sneaker_ger; 10th November 2016 at 19:59. |
