madVR - high quality video renderer (GPU assisted)

[huhn]

on a UHD screen quadruple isn't used for 1080 sources.

after reading the profiles more there is no profile for 720p try the HD profiles.

odd sorting for me but it should work perfectly.

I have a question.

Is madVR best upscaling method better than nnedi3/eedi3 upscaling?

Edit: Another question: is madVr deinterlacing method better than QTGMC?

[huhn]

NGU aa replaced nnedi3.

deint depends on your hardware and is generally not better than QTGMC when high settings are used.

[tp4tissue]

I'm not against NGU, but I truly feel it's using way too much electricity to do what it does. At 30* fov, I can barely barely make out the difference between Nearest neighbor and NGU-VeryHigh Sharp, I guessed wrong 50% of the time NGU vs Lanczos. If I wasn't looking for the difference I don't think I'd see it on anything except animated shows. I've tested this on multiple full bitrate blurays.

If anyone's Green Conscious, I highly recommend sticking with Lanczos for Earth's sake. For anyone' that's been near the Oregan fires. sigh.. it's important.

It's not much power really if you're watching a couple of hours every night which I would guess most probably are not..
You're doing it wrong if you're blindly setting things without looking at the results, I've said this many times to those wanting to know "best settings"
Many are limited by what their cards can push anyway and the rest.. they don't care.. they plonk $1500 on a card and set everything to max 'cos they can.

As long as you're happy we're happy, people really shouldn't judge others choices. Lanczos is a solid resizing algo.
My own choices are based on power usage/noise and visual results. Very high settings are overkill, we all know it.

I've compared QTGMC with default settings and CUVID deinterlacing. To my taste, QTGMC flattens the image too much. Also, my Ryzen 3800X could run QTGMC in realtime for SD videos only.

Edge-directed upscaling methods like NGU have their limitations. There will no much difference between NGU Sharp vs Lanczos when upscaling soft SD videos or upscaling with a small coefficient. However, I always use NGU Sharp because it also provides RCA for free.

May I have the present link to the latest madVR beta; I mean I found through search that "madVRhdrMeasure115.zip" is the latest but on avs forums there's some buzz about a hotfix or something. I would like to apologize beforehand if I am not being clear about the same enough. Also, if I may I would like to ask: "madVRhdrMeasure115.zip" file is almost half the size of "madVRhdrMeasure114.zip", is the installation same as beta 114 (install madVR0.92.17 then overwrite with files inside "madVRhdrMeasure114.zip") or (for beta 115) install madVR0.92.17 then overwrite with files inside "madVRhdrMeasure114.zip" and again overwrite with "madVRhdrMeasure115.zip"?
Thank you.

It's easy to rationalize personal use, drop in the ocean, but there are alot of drops, and it makes for a sizable chunk of the ocean.

I'm not against people turning it up, I'm just saying we have to be careful in using these rationalizations.

If you've got half a can of soda left, you can drink it later, you don't just pour it out. It works the same with electricity in the current situation, but it's hard to visualize it that way, because the cost is perceptually distant from point of use.

Tell this to GPU manufacturers who call innovation by putting as many sms into the GPU not caring about power usage, let alone miners with their 24/7 usage... And I could keep continue on-and-on...

Again, just because there exist worse bad guys, is not justification or exemption for our own personal choices.

Just extract into the existing madVR folder. Make sure LAV filters are also updated to at least 0.74.1 https://files.1f0.de/lavf/nightly/?C=M;O=A

[HillieSan]

What does 118 improve or fix?

[VBB]

Nothing, unless you're tone-mapping. All the betas are basically for testing and improving this particular feature.

[crossclass]

Thank you.
But I have to ask:
You said "...extract into the existing madVR folder", but my existing madVR folder is composed of madVR 0.92.17 + Beta 114, extract into it or fresh install madVR 0.92.17 then overwrite with Beta 118?
Thanks again.

[huhn]

doesn't matter. all beta releases replace the same files. just make sure it is 0.92.17 or a beta version where you update over just to be save.

Hi and happy new year!

How does madvr detect hdr and where does it get the essential information?
I want to render a not tone mapped 4k hdr stream from a capture card, but madvr does not detect the video stream as hdr. For matrix, primaries and color range it only does a "(best guess)" with bt.709 and limited. When looking at the pin info, there is only VIDEOINFOHEADER set, but no VIDEOINFOHEADER2 with DWCONTROLFLAGS.
Is it possible to inject this information upstream of madvr or force madvr to do a "best guess" with bt.2020?

Pin info for the capture stream from the capture card:

My monitor isn't wanting to exactly hit 23.976hz, even though it supposedly supports it. Whether I change the refresh rate in Nvidia control panel or add a display mode in madVR for 2560x1440p144, the display settles in around 23.938hz, causing a dropped frame ever 25-26 seconds. Is there a way I can get my refresh closer to 23.976? Or is this just the result of my display being a GAMER(tm) display and not a TV? In the past, I've always used Reclock to get better syncing, but I recently did a full reinstall and am starting from scratch.


For reference:
Monitor - Acer Predator XB271HU (1440p, 144hz)
GPU - RTX 3090
RAM - 32GB
Windows - 2004

EDIT: ah, snap, I missed that it's a live stream and not a file. The shortcuts for the matrix and primaries will work but I don't know how to force HDR without the filename trick.
You can add parameters to the file name itself to force them. "<filename> primaries=bt2020 matrix=bt2020 transfer=hdr.<extension>" will force what you want.
For matrix and primaries you can also use Ctrl+Alt+Shift+M and Ctrl+Alt+Shift+P shortcuts to toggle them.

Not 100% true, AFAIK it's the only one but test build 113 enhanced rendering efficiency to better use the GPU (IIRC "allow a higher percentage of GPU usage before frames start to drop").

So beta build 113 is better than the latest 0.92.17?

The filename parameters work perfect for files. Didn't know that.
Unfortunately i need something that works for the live stream. Is there also a shortcut equivalent to the "transfer=hdr" parameter? Matrix and Primaries toggle don't force the stream to hdr.
