madVR - high quality video renderer (GPU assisted)

[phm]

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?

[sneaker_ger]

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.

I can only talk about the 720p version (higher is not supported by the downloader I've uses), but the downloaded version of this specific video does not seem to have HDR metadata (resulting in a "flat" look).

This specific one seems to be true HDR apart from the missing metadata, but I've seen others [1] which seem to be delivered as already rendered to SDR (can't check on a HDR display because I don't have one).

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.

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)?

[sneaker_ger]

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?)

[huhn]

go to device -> "your device" -> properties -> the display expects the following RGB output levels: set it so TV level(16-235) and you will get the same nearly for sure wrong and under saturated image as VMR

Thanks guys. That all desired settings (but for faster change them I want possibility to type digits from keyboard in fields directly and may be cusomize one click presets - there is many space in properties and color & gsmma tabs for that). Of course, sometimes 0-255 is better, sometimes 16-235 - depends on played video.

I always turned off any "video enhancements" even if they was turned on by manufacturer as default. So I don't like .NET and so AMD (was ATI) Control Panel I not even installed I turned off all "video enhancements" by watching key {} in HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\VIDEO\Video0 and changing keys like this:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{A104160B-A34F-400E-AC50-C14942E8E718}\0000]
"TRDenoise"="0"
"DXVA_WMV"="0"
And reboot after changes.
Question about HDR: do all see trees "in fire" between green trees from 11 to 21 second in Samsung_HDR_Wonderland.ts http://demo-uhd3d.com/fiche.php?cat=uhd&id=153 especially if compare with EVR? I've never seen so saturated colors in nature so I think the truth between madVR and EVR - am I wrong?

no if the file is correct created madVr knows the levels and will handle them correctly.

a file that is full range without full range flag is broken and nothing else.

[Ver Greeneyes]

If a file is wrongly detected as full range when it should be using TV range, or if it's detected as TV range but it actually needs to be expanded twice, just use the hotkey Ctrl+Shift+Alt+I to adjust the source levels used by madVR.

[sauma144]

I cross my fingers and hope this weekend will be THE weekend.

huhn, Ver Greeneyes
Thanks once more (it's a pity this forum havn't Thanks button).
And what about my question about HDR file?
sauma144
What did you mean? May be you are Formula1 fan as I am? I cross my fingers about Lewis Hamilton but not all in his hands due to broken engines across this season.

[huhn]

with the HDR problem please make a screen with the OSD(control+j).
this file has Bt 2020 colors and no display is able to display them and it is a HDR demo i wouldn't be shocked if the this file was created with wrong colors in mind but i haven't watch it.

edit: and madshi doesn't answer questions right now not until "THE" weekend. which is when it's done

I'll do it after 14:00 GMT+3

I am novice in this thread so can you provide link what is waiting for THE weekend?

[huhn]

people are hyped about the new scaling algorithm "NG1".
which will be released "when it's done".

hello folks, I need some advice you think is best to create a 3d lut with BT2020 BT 709 or use the mad in upscalink 1080p to 4K know that my projector does not have a gammut of BT2020 do you advise me to do?
thank you

[huhn]

what has upscaling to do with colorspaces?

if your devise doesn't have a gamut of BT 2020 (of cause it doesn't) a proper 3D LUT will take care of it.

Thanks. As I assume will be less aliasing with "NG1", don't it?
