madVR - high quality video renderer (GPU assisted)

[webs0r]

My 3c on the UI (I stayed on the v0.91.1 version for now as I was scared of losing the fastest doubler (s-xbr for me)+control - so haven't seen the new).

There are 2 main use cases:
(1) Upscaling

And then the progression is:
(a) upscaling -> (c) downscaling -> (d) refinements

These a-c could be on tabs going horizontally.

For the doubling, I feel a system where there is a blank array initially and the user can add items in corresponding to doubling instructions would be easier to use.
Each entry: trigger scaling factor, algorithm, (any modifers)
A modifier could be the s-xbr sharpness and bloating, or NNEDI32 neurons or NGU quality level.
So 2 entries would give the user quadrupling.

Final sizing would be similar to the 0.91.1 image upscaling but yeah, it could just use drop downs instead. In fact, this could be a mandatory line on the array - with a final resize trigger, and for that one the user can choose from the much wider array of scalers and options.

For chroma, maybe duplicate that?
The interesting thing here is, should the first chroma item be the initial chroma doubling? And then the final resize - could be anything, making it independent to the luma... don't know if its a good thing.
Another option is to combine the two - if user specifies a luma doubler they have to choose whether to double chroma or not at the same time. But then we'll need a separate initial chroma doubling option.

(2) Downscaling
Just the "final" scalers.

This makes more sense as the downscaling tab in the upscaling section only applies when supersampling, and you can have a different downscaler for when final size is <1.0.
I'm not sure this is where people/madshi want it to go - because it preserves the customisability of the old system and just improves the "flow". If simplification is required then options would have to go.
And I don't mean options as in algos - I mean things like - the ability to tailor that you want NGU-high for the first double and then NGU-low for the quadruple step. For example, a user could specify they want doubling, then input a supersampling ratio (1.0 for no supersampling or 2.0 to go to double the screen res) then just choose 1 option like NGU-med and that is applied for all doubling steps that brings it to (or over) the 2.0 ratio.

Not sure what to do about presets and such - I like the simple scripting system. Maybe a link to an external guide will do rather than baking in presets.

Otherwise, somewhere there could be a Fastest, Balanced and Quality. Or 5 options if preferred. These would just pre-populate the above settings dialogs -> allowing scripts to still run. The tricky bit is, like in my situation, when I have a high frame rate video I'll drop to lower power scaling algorithms, but also change the dithering method etc. Gets tricky. Probably not worth it yet?

Sorry, I should have probably installed the latest ver to take a look. Hope there is something useful in my rambling.

what's your problem even a GTX 960 can do FHD -> UHD 23p with NGU high.

Maybe he just doesn't like super sharp scalers.. :3

can't u see got he got issue? majority cards can do it but can it run properly w/o issue is another thing!

opposite here
dont know if plasma motion with PWM works better with super res than it does with LCDs sample and hold.
on screenshots comparisions there is NO difference at all but it is when the movie is running.
with NGU high and SuperRes 4 here picture looks more high res and less messy as i have described.
SuperRes must do something to smooth the frames together in motion as its only there there is a difference.

maybe madshi can confirm whenever superes for chroma upscaling does something to the image in motion or not?

[huhn]

i don't think this is setting related.

he has a problem with madVR PAUSED not in playback.

Hi,

I'm a problem about the video quality when using a video projector.
I set up MadVr using Warner306 recommandations available here

With my 60" 4K TV, the video quality is awesome. When using the same configuration on a 4K video projector (3,5m so 138"), image is not so detailed/sharp and a simple BD player offer a better quality.

What is the problem ?

Regards

[huhn]

what projector?

Asmodian can you clarify something to me?

I do not have any dropped frame or particular problem but looks like is suggested to change from the default optimail power to maximum or at least adaptive, but how? I mean... in the setting page below or you let the application manage the settings or you decide but then there are many other settings to check not only the one about power usage. Am I missing something? If not...what else should I choose or select other then the power settings?

Hope you can help.

[huhn]

just leave the rest of the settings at default and change power management to adaptive.

Another question about graphic card.
I want to outptut all my videos to 4k(24-60) - full RGB - 10 bits

What is the best between Nvidia GTX 1060 and AMD RX 480 ?
No issue with the new AMD cards (like 10 bits dithering) ? I always owned Nvidia till now...

I want to be able to run:

2160p video
Chroma: NGU high quality
Image: Jinc3 + AR
Image doubling: Off
Upscaling refinement: Off
Artifact removal - Debanding: Medium/High
Artifact removal - Deringing: Off
Image enhancements: crispen edges (0.5) + AR
Dithering: Error Diffusion 2

1080p video
Chroma: NGU high quality
Image: Jinc3 + AR
Double Luma: 2.0x or greater - NGU high quality
Double Chroma: Off
Upscaling refinement: soften edges (1)
Artifact removal - Debanding: Medium/High
Artifact removal - Deringing: Off
Image enhancements: Off
Dithering: Error Diffusion 2

The nvidia in full RGB do not support 10-bit but only 8 bits

Nvidia 10x supports 10 bits only at 30Hz and lower (when outputting to 4k).
Is it different with RX480 (Polaris) ?

no card ca output 4:4:4@2160p@60hz@10bit via hdmi 2.0. It is an limitations of said interface

Ok so Nvidia GTX 1060 or AMD RX 480 ?

And what about the problem with an EPSON 9300 (4k,10bits, HDCP 2.2, .. compliant) ?

I can't adjust any settings with the newest version, it only has "create profile" group button that shows me a menu for what to create a profile group for.

Except when I select something and hit OK, now the button is disabled and I still don't have any settings I can change. Any idea how to fix this?

the projector is 1080p it only supports UHD input. for best quality it is most likely better to stick to 1080p

try reset to defaults. but this sounds strange did you update madVR while it was still running?

Try disabling soften edges in upscaling refinement if you find the image too soft.

I wonder if I should recommend soften edges for any profile. I am still undecided on its value.

It is in the advanced settings page, not adjust with preview. As huhn said, leave the other options at their defaults.
