Could NVIDIA's default optimal power vs adaptive power be causing this reboot on madvr paused + display idle/off?

You cannot do anything like this with madVR running, e.g. sleeping the computer has a similar result.
Actually sleeping the computer (or at least, having the monitors turned off and therefore video as well) doesn't result in that. If there isn't buggy code for the architecture in the driver related to this when you wake it up again you simply have to double-click back to windowed mode and then again back to full screen to reset it. I believe this also works for full screen windowed mode, but I doi t for full screen exclusive mode.

With my R9-280X it worked, when I first got the RX480 it didn't (possibly requiring a cold restart of the computer), but now with 16.12.1 it works again.

I do not find a good setup to see old remastered movies 2k to 4k. They are very noisy. Can somebody help me?

I'm using the latest version of madvr with this configuration:

luma: very high
chroma: let madvr decide
upscaling/downscaling: let madvr decide.

Without any upscaling refinement


I would appreciate any help.

Thks

For old movies I suggest:

NNEDI3 128
luma: doubling: 128 neurons, quadrupling: 32 neurons
chroma: let madVR decide
upscaling/downscaling: let madvr decide

NNEDI3 is great for older video content while NGU is great for native HD content.

Hi,

When looking at HDR (10 bits, HEVC) video on MadVr(Jriver), I get a black screen.
My display is full 4k / HDR / HDCP 2.2 compliant and my graphic card too (Nvidia GTX1070).

Is there any recommanded settings or user guide (MadVr/Nvidia control pannel) for watching a HDR video on my HTPC ?

Thx

I'll try the configuration you recommend. I'll tell you later.

Nnedi3 128 for chroma upscaling, right?

Update

I tried it. It looks a little better. But the render time is high. 40ms. Is a remux file of 30 gb with bit rate 41.6mb/s. I use gtx 1080 g1 oc.

No, I never use over NNEDI3 64 for chroma upscaling, and that is for SD where the performance hit is almost non-existent as any improvement is unnoticable. NNEDI3 32 would be my max for HD, especially remastered content.

I meant NNEDI3 128 for luma doubling to 4K, but of course that depends on which GPU you have. NNEDI3 128 runs at about the same speed as NGU veryHigh for me so I hoped you could run it as well. I can run NNEDI3 256 for 1080p24 -> 2160 so I might be overestimating what is possible.

My gpu is nvidia gtx 1080 gaming g1 (oc 2150mhz) All with the same mkv remux file (30gb bit rate 40mb/s) without compressiono...

Chroma upscaling nnedi3 32
Image upscaling NNEDI3 doubling 256 quadrupling 32
Render time 58 ms
Others option let madvr decide

Chroma upscaling nnedi3 32
Image upscaling NNEDI3 doubling 128 quadrupling 32

Chroma upscaling nnedi3 32

Render time 24 ms
Others option let madvr decide

Chroma upscaling NGU high
Image upscaling NGU high
Render time 19 ms
Others option let madvr decide

Chroma upscaling NGU high
Image upscaling NGU very high
Render time 40 ms
Others option let madvr decide

Render times are very bad. I do not understand why.
This gpu is the fastest I found.

Fired up the 30th anniversary of Transformers the Movie tonight (It looks amazing) and I'm quite happy with super-xbr 150 AR
being used for chroma upscaling for this type of content.

There's a number of scenes like this and they all show similar benefit. NGU doesn't do too good here, thinning lines and being softer than super-xbr 150 AR (even NGU very high SR4!)
Where as super-xbr 150 is keeping the same line thickness but giving it some nice line darkening. Can post more scenes if anyone would like to see them.

Check it out.

I'm interested to see more screenshots. It's a great example to show that chroma does count.

Could you post screenshots of this scene with Jinc or NNEDI3 32/64 neurons just to see the results? I didn't expect that super-xbr was so good actually, I aslo find it better than NGU very high in this example.

Thanks. This isn't just limited to red scenes either, but this scene really does look to be a good test for comparisons of chroma scalers and is a full quality rip of the blu-ray.

As you'd expect based on what I've said previously NNEDI3 32 neurons and 64 neurons are almost identical, 64 is a waste of resources IMO :P
I think NNEDI3 has the edge here but it's slight.

Jinc AR vs NNEDI3 64 neurons.
NNEDI3 32 neurons vs NNEDI3 64 neurons.

Thats useless as it also depends on the display you use.
And they also performs different in motion.
Static screenshots and the image you get when the movie is running is not the same.
Plasma tvs for example has much higher motion resolution than lcds or oleds and so they will show a sharper image.

You are not maximizing madvrs upscaling algorithms on an LCD or OLED lol
300 lines is sub DVD resolution in motion.
Plasma tvs can show all 1080 lines from Blu Ray content

Thanks! I think too that NNEDI3 64 neurons is a waste of resources for chroma, I just wanted to check.

Super-xbr 150 is the sharpest between all these options but I find that Jinc is still a great performer when you consider that it doesn't need much resources. NGU low could be a great deal too.

Super-xbr is much more polyvalent, with values of 100-150.
I use NGU-Med at the moment (or NGU-High on new versions), because it is overall sharper and cleaner... and it is cold now where I live

Example with BilateralSharp / Bicubic60 AR / super-xbr150 / NGU-Low / NGU-Med / NGU-High :



I zoom for you in the right spot :



Now I let you decide which one to use.
But in this scene, I find NGU high a lot better than Super-xbr 150, even NGU low is better. The pearls are more defined with NGU.

In the screens by Neo-XP I actually think BilateralSharp looks best. Compare the red on the neck. All other algorithms seem to bleed the red into the surrounding skin colour. I'd be interested in how reconstruction soft performed in that image.

Those look fine actually, I was hoping NNEDI3 128 would be faster for you but that isn't too far off. I have a Titan X (Pascal), OC 2050 MHz.

Look again...the reds are bleeding together in Bilateral and there is no separation between the bright and dark red beads.

Yes they are. But the red on the neck bleeds into the skin colour (the red part slightly to the left between the two black parts). It is a very noticeable artefact imho.

I'm sure madshi will improve NGU when he adds the luma lookup into it.

Titan x Pascal Is more powerfull. Significantly more render output processors 96 vs 64 and more cuda cores 3,072 vs 2,560...

Gtx 1080 + madvr with new movies, like guardians of the galaxy, NGU It does very well. The colors and details look great on my tv oled 4k tv...

Chroma upscaling NGU high
Image upscaling luma + chroma NGU very high
Crop black bars
Upscaling refinement enhance detail 1.5
Others option let madvr decide
Render time 26 ms
