madVR - high quality video renderer (GPU assisted)

I'm quite liking the new GUI so far.

I don't think there is a way with profiles to override the forced algorithms used after image doubling unfortunately.

For instance, to use Catmull-Rom AR LL for downscaling after 720p to 1080p doubling.

I recommend that everyone who wants a particular option available post a screenshot showing the improvement with your content. madshi has always been responsive to suggestions when shown real benefits.

most content is 23p (24000/1001 hz) and 25/50 content will judder at 120 hz.
smoothmotion is very useful for 120 HZ screen and like said before audio clock issue are fixed too.

It doesn't work. not at 120 or 144hz, it simply doesn't switch on itself unless you force it
it works only for very rare 30 fps on 144hz, it doesn't work on 120

Can you post a screenshot please? Maybe i'm testing on wrong SD content, just curious.

Please post comparisons, personally i'm simply curious what I can't see you can.

And you can actually use lanczos for upscaling luma/chroma but without doubling. But didn't it do the same job before?
ngu double->lanczos upscaling of doubled image if resolution was still too low pretty much negating ngu double?

I tried, anyway. NGU does have nice detail, and it's still fast. sXBR is softer overall and doesn't introduce any patterns even on higher sharpness.

Look at Deacon's hand or the windowblinds for example. There's a fuzzyness that you can spot in the cereal lettering. Look at the second house from the right, as well as the brick fence. NGU turns lines into jaggies. On the plus side it curbs ringing better than sXBR. These shots are without any further enhancements, just chroma, doubling and scaling.

Also when watching this SD stuff with compression artifacts in it, NGU makes these much more obvious in the moving picture, while sXBR tends to gloss over them. Stills don't really show this too well.

Anyway.. I don't expect you to agree with this. I like the soft-to-medium scalers the most so on that point I'm probably the odd man out.

I think NGU wins in all of the above images... I also detest softness, so that may be why I think NGU wins

Yeah, I don't really understand that, I hate blur, I have enough of that in real life. I think you can lower those artifacts on NGU a bit with thin edges and sharpen edges 0.5(or even lower) with AR and optional AB. Image enchantments tab, they are not resource hungry.
LumaSharpen sometimes helps, but not with every source.
You probably tried that already, works for me, maybe will for someone else.

Oh and also do not forget about soften edges in refinement.

I need your advice I have a nvidia 1070 GTX video card do you think it's worth having a GTX 1080 to make better use madVR?

Upgrading from 1070 to 1080 is not worth it. Maybe upgrading to 1080Ti in january, or wait for Volta.

[Mistery 73]

thank you Betroz

if you use two 1070 GTX graphics cards in SLI get excellent results with madVR?

No, MadVr do not support SLI.

no, for one it doesn't support it
how fast do you want it to be? 1070 already crashes most ridiculous madvr settings

I can have the same thing or even better (6.3 min for frame repeated) if I create custom resolution with 119.88hz (exact multiple of 23.976).

With 119.88 or 120hz or reclock, I have never seen the difference. Have you a recording to see the difference?

of cause a custom resolution or reclock can fix this issue. obviously it can fix this issue.

a custom resolution is complicated to use.
reclock is resampling audio which isn't perfect.
smoothmotion is blending frame which isn't perfect but save at 120 hz and very easy to use. at least for people that read the smooth motion options...

i'm not even starting about 144 hz and that the most common refresh rate is 59p (TV broad cast) followed by 50p (broadcast) and they will judder at?

try option two in smoothmotion.

I use a GTX 1070 for MadVR on my HTPC for upscaling to a 65" 4k TV. I don't see that I'm limited by the GPU in any way regarding the settings for maximum quality as long as choices are kept reasonable (as in actually making a difference in quality instead of trying to max out everything).

I think the new settings dialogues are quite good and very closely correspond to the settings I would use anyway. They are much more friendly to new users. If possible, I think chroma upscaling should still be merged into the same settings menu since new users probably don't even know what the difference is. Then the settings UI would be streamlined with either simple Upscaling or Downscaling menus.

I think the problems some users are having with the new settings could be alleviated by making the use of profiles much easier with an UI. For example the workflow of adding a profile could be as such: "add new profile button" -> next up checkboxes with different content (SD, 720p23, 1080p23, 1080p60, custom etc) - select one - then enter your target monitor resolution. After that MadVR would show what scaling factor needs to be used and their respective scaling steps. For each step there would be a dropdown with selectable algos for chroma/luma (either similar auto selections for quality like now or user-selectable). If no profile is created for said content type, madVR would use the algos selected in the current menu.

Also, I agree with previous commenters that if you think a certain pre-selected algo does not produce close to the quality that your favourite choice does, why not grab a screenshot or two showing the difference on actual content? If the difference is so apparent that you can easily see it, then prove it and I'm quite sure the madshi will consider making changes The human mind really easily plays tricks on you so it's always best to actually confirm what you think you are seeing.

With my old PC (I7 920, HD 7770, PCIe 2.0), super-xbr is less hungry than NNEDI and NGU even if I can use NGU low or med , ,depending original size of the video.

720p to UHD, can't use only image doubling + Lanczos3 AR anymore.

Which setting should I use with an onboard Intel HD4600?

I didn't know reclock resamples audio, one more reason(besides x64) not to use it, MPCHC WASAPI support is great.

I can't tell with 24fps content if smooth motion does anything at all at 120/144hz even if I force it.

But 0.91.3 looks better. More detail. It's just too slow? I see your problem then, it was a better compromise before.

if you don't see the repeated frame every ~42 secs fine but it is still there.

and you said you don't see a difference with smooth motion so it is not doing anything bad for your eyes too. so you can use it to stop repeated/dropped frames from sync issues.
