madVR - high quality video renderer (GPU assisted)

[huhn]

with nvidia in works in older windows version too.

[XTrojan]

Yes, full HDR passthrough in win10. The TV detects HDR. Works perfect on nvidia and I think amd is fixed too now. I prefer the output of madvr over my expensive bluray player.

Ok, gotta test this, do I need to enable/disable Windows HDR since it seems to be bugging on HDR games, where the games handle the HDR themselves

[cyberscott]

Those VP9 HDR YouTube streams definitely play just fine when you download them first, no clue about getting streaming to work.

I’ve gotten HDR to work on VP9 YouTube steaming but it is really hit or miss. Downloading them first is a much better solution currently.

Keep Windows HDR toggle to off. Set madvr to passthrough HDR (enable send HDR metadata to display as well). Enable D3D11 in rendering->general settings.

When madvr detects HDR video it will automatically trigger your HDR capable display. On exit, back to SDR.

I have this working well on latest nvidia drivers + latest madvr. Both on FSE or windowed.

I have not been able to get youtube HDR to trigger my display into HDR (using jdownloader to download offline). The usual demos from uhd3d work fine. Maybe i need to use a different downloader?

Edit: Tried forcing the download to only VP9 HDR variants, but still no autoswitching to HDR. Using MPC-HC+madvr+lav nightly. All latest with nvidia.

[Manni]

i don't see a reason it should not work. are you sure you got the correct VP9 10 bit version?

Thanks guys.

I have no interest in streaming, I'm talking about playing Youtube HDR videos offline.

I'm using 4K Downloader to download the videos, and after checking the files, they are not HDR despite requesting the original 8K or 4K version.

I don't know if other tools are better at selecting the HDR version of the file, it doesn't seem possible with this software.

Please PM me if you can recommend a tool able to download the HDR version of a Youtube HDR video that can then be played with MPC-BE/MadVR/LAV.

Thanks.

Best video downloader tool I've used so far : https://yd.3dyd.com/download/ (same guy who does the youtube ds filter).

[aufkrawall]

To download Youtube HDR video with proper HDR metadata:
-get youtube-dl (http://youtube-dl.org/)
-get ffmpeg build (http://ffmpeg.zeranoe.com/builds/)
-copy both youtube-dl.exe and ffmpeg.exe to the same location
-run via CLI "youtube-dl -f ((bestvideo[vcodec=vp9.2]/bestvideo[vcodec=vp9]/bestvideo)+(bestaudio[acodec=opus]/bestaudio[acodec=vorbis]/bestaudio[acodec=aac]/bestaudio))/best https://youtu.be/tO01J-M3g0U" (without " and change YT URL)

Some players also support directly playing HDR video that way (unfortunately, I don't know any which support madVR).
The command above is not the shortest possible, but it should always download best available formats.

Edit: Should also add that I didn't invent the format line but received help at youtube-dl Github myself.

Youtube has both SDR as well as HDR for all resolutions. So the resolution doesn't tell you anything. Like aufkrawall said you need to download the HDR streams specifically ("vp9.2", VP9 profile 2, VP9 10 bit).

Thanks both, 3Dyd was the easy way. Unlike 4K Downloader, I was able to select the VP9 HDR HFR version (Webm), which was played in HDR perfectly by MPC-BE/LAV/MadVR. Thanks again for all the help. :thanks:

I don't think I am getting hw decoding though. The video drops frames constantly. Is it not supported in gtx 1080? I am using the latest lav nightly and madvr. vp9 is enabled in the list of hw decoders. I have tried cuvid, dxva2 native and dxva2 copyback.

Ive been wondering why for a long time why when I upscale Pal DVDs 720x576 to 4K why they never quite fit the left and right side of my motorised masking when set to 4x3. Top and bottom is fine but the left and right sides are less than the masking....

Is it because the scaling is an odd amount to scale and doesnt double correctly like 1920x1080 to 3840x2160 does?

Since scaling a 4.3 DVD 720x576 > 1920x1080 > 3840x2160 is none of the reasons the images doesnt scale to the same size width as a 1080 BD 4.3, does, should it or should it not scale the same.

If it should be the same, can you give me a clue please why?
I was wondering if madvr was changing the pixel ratio a bit for 720x576 to 4K....

It can happen that they are not the same: picture on DVD is anamorphic.
Check the OSD of madvr for the actual size.

[70MM]

DVD isnt anamorphic. OSD states 720x576.

[nevcairiel]

DVD isnt anamorphic. OSD states 720x576.

720x576 isn't 4:3 though, so if its not anamorphic (which it really should be, though), then that explains why its screwed up.

Could it be because the outer 18 pixels of a 720x576 frame aren't supposed to be seen? That's why, when converted to square pixels, a 720x576 16:9 source ends up being 1050x576. What should happen is the outer 18 pixels get cropped before the conversion, so you'd actually be stretching 702x576 to 1024x576. Obviously no media player will do this, so instead you'll often end up with small black bars at the top and bottom and, often, black bars or dodgy analogue crap at the left and right edges that are part of the original image.

Examples are below, first what you should normally see in a 16:9 frame if the file is tagged with the correct ~1.458 pixel aspect ratio, and second what you'd see with MadVR's black bar detection enabled.

Sadly, many PAL DVDs don't adhere to the standards (particularly films which are just encoded as 720x576 16:9, i.e. pixel aspect ratio of ~1.422), so it's kind of a crapshoot when deciding how to mux the videos properly when ripping them.

P.S. The same thing applies to 4:3 PAL videos: only the centre 702 "lines" are meant to be part of the image stretched to 768, so for a 720x576 original image it should be 788x576 without any cropping.

Does LG Real Cinema effect this ?

it says Optimize display for movies.

What's the difference between 'crop black bars' and 'if there are big black bars'? With the second I can effectively crop the bars away. What about the first?

That is not the way to be using your OLED. If you have a good GFX card you should have the resolution set at 12bit 2160p 23 or 24 fps in windows (and madvr if your using the resolution swapping options). Have madVR set at 10bit or greater for the panel and let madVR do the upscaling for you from 1080p to 2160p. The panel will force the real cinema option on. On my E6 I have an audio delay of 100ms set on my AVR.

[Razoola]

Not that I'm aware of. Look at product release slides, hardware reviews and the "Evaluation of HEVC decoders (SW, Hybrid and HW)" thread of this forum. You can also ask there.

Anyone tried sending HDR metadata through their receiver? I have RX-1040 which has HDMI 2.0, but is said to not support HDR since it doesn't support HDCP 2.2, but madVR has no HDCP. Afaik receivers should just "passthrough" everything to the TV except the audio but does this apply to HDR metadata? I'll test it when I get home unless anyone can enlighten me :D.

Unfortunately NVIDIA didn't change their classification for VP9 10-bit, probably because VDPAU (which this list is based on) doesn't even support it.

HDCP 2.2 has nothing to do with HDR and isn't needed, especially from MadVR.

What's needed for HDR10 is HDMI 2.0a (or HDMI 2.0b, but HDMI 2.0 isn't enough), and no, all AVRs don't pass through BT2020/HDR info. For example, I had to get rid of my X5200W because it wouldn't pass through BT2020 content. I replaced it with a X7200WA which does, but doesn't pass through Dolby Vision until it gets a f/w update in the next few months.

Of course you can always ask MadVR to convert HDR to SDR (which it does very well), and then any AVR/display will work.

Of course you can always ask MadVR to convert HDR to SDR (which it does very well), and then any AVR/display will work.

So the better idea is then to connect to the TV directly and then send the audio to the receiver via ARC? unfortunately this means no DTS-HD or TrueHD :(. Would it be possible to decode TrueHD and then send it via ARC or is the bandwidth not enough via ARC?

Edit: ARC equals S/PDIF, well that sucks, is the only option then buying a soundcard to the PC or buying a new receiver?

Hmm, forgot about that. My AVR does do UHD passthrough but I doubt it'd pass HDR data through. So when I get a UHD HDR TV I'll have to upgrade both my AVR and my GPU. >_>

Or use MadVR's HDR to SDR conversion which is excellent and save on gear.

For me, upgrading the AVR made sense because my source is aa UB900 until we can rip our UHD Blurays.

But if you plan to use a HTPC as a source, there are few reasons to upgrade anything in between.

You have to realise that "HDR" only means applying the correct gamut/gamma. Ultimately, HDR displays convert to SDR. So asking MadVR to convert to SDR and send SDR to the display through the AVR is very similar. Sometimes, you can get more control with the calibration in the display, but MadVR does a great job especially if you're not a HDR calibration expert.

[el Filou]

Ultimately, HDR displays convert to SDR. So asking MadVR to convert to SDR and send SDR to the display through the AVR is very similar.But the display tone-maps to what it can really display, while madVR tone-maps to sRGB, right?

no depends on your settings.

In 24 Hz mode with real cinema enabled it has a very high amount of input lag. I have to set the audio delay in lav filters to around 90ms to get the audio in sync.



Thank you !! I will test it , so 90 ms is the best one ? seems like it .

Back to my 720x576 DVDs that seem to be a bit small on my 16X9 screen when I set the motorised black masking to 4X3 as in this image. It always seems ok on 720x480 DVDs...
OSD states movie 720X576
Scale 0,0,720,576 > 480,0,3360,2160, is this correct?

What does the 480 mean?
and why is the 3360 not 3840 like my 16x9 BDs are?
I just dont understand the scaling...
https://snag.gy/Hvj2CT.jpg

[huhn]

the displayed image is 2880x2160 4/3.

the number 480 is the start where madVR starts drawing the image and the 3360 is the point where madVR stops drawing the image. so yes it is correct.

the problem is your screen is at 4/3 with a 16/9 resolution and you didn't tell madVR that this is the case. but madVR can be setup for this.
you go to devices set your device digital projector and try the screen config settings.

[70MM]

That setting in there is for anamorphic stretch, I dont want that as Im not using a lens in this situation. The only other settings on that page are for cropping, I dont want to crop the image.

That seems perfectly normal to me. At 4K, a 4:3 resolution would be 2880x2160, so you get 480 pixel letterboxing on each side to fill the 3840 width - perfect 4:3.
The numbers there define the display rectangle of the image (the start and end of the image), it starts at left 480, and ends at left 3360 - ie. its 2880 wide and centered, just like it should be for 4:3. Obviously for 16:9 it would fill the entire screen, so the start would be 0 and the end 3840 - but 4:3 doesn't fill the entire screen, so there is letterboxing, which those numbers express.

madVR is doing exactly what it should be doing.

[70MM]

Thanks nevcairiel for that explanation. Im pleased that madvr is doing the right thing, what isnt then is many of the 576 DVDs.
99% of my classic BDs that are 4x3 fit perfectly within the motorised preset side masking I have set for 4.3, 16.9 and scope 2.35.
The presets are setup correctly from the Spears & Munsil test disc.

However may of the 4x3 DVDs I have the left and right edges miss the preset 4.3 side masking, unlike their BD cousins.
I can fix this with the zoom control, but the smallest % any of us can use is 25% zoom.
Using 25% zoom in this scenario is way to big and overshoots the 4x3 masking ratio up to approx 1.66 ratio, whereby cropping the top and bottom of the image too much.

I really wish madshi would make some smaller zoom steps e.g. 5%, 10%, 15%, 20%, 25%, this would fix these incorrect sizings from some DVDs on 4x3 material.
It would be a very simple fix, not important for most who use monitors or TVs, but those with projectors and masking it would be a very welcome bonus!
I did mention this many months ago, as I also use the zoom control for some of the odd scope ratios that arnt 2.35, like Ben Hur and many of the very early Fox scope titles that are wider than todays scope.
The 25% often zooms up too large, having smaller steps would be great for us guys with projectors and motorised masking...wink wink :)

Yes, that does not help with the LG OLEDs, to be honest the LG panels have serious issues with the way they handle ARC and stuff. I found the solution is to have everything go via the AVR first.
