For me, ET + ES + AB150 + AR will eliminate aliasing that WAS there.

Here is the trick: If I am rendering to a 1080 screen, I must use either upscaling refinement if the video is under 1080 OR image enhancements if the video is 1080.

Upscaling refinement takes significantly longer to process (rendering time) because I have it set to apply after every 2X step, but produces perfect results.

Same can be said about image enhancements, if used only when video is already the same resolution as display.

At such high values, there will be *small* distortion, but it still better than without those algorithms.

There are anime that are already over-smooth, and those would be distorted. On this same note, I seriously think that the reason I like ET + ES + AR + AB at such high values is that I personally have either bad encodes, or anime that were drawn too fuzzy for these resolutions. I checked with some more, especially new anime, and it works magic for half, while it distorts the other half, inducing aliasing and distorting objects.

@madshi Is there any possibility of inducing an aggressive anti aliasing algorithm?

and why don't you post a screen than?

Wow! With earlier versions of madVR I was unable to force 2x SuperSampling for Luma Doubling NNEDI3 32n + Chroma Upscaling NNEDI3 32n in 1080p videos without severe frame drops, but now I can. However, it only works fine in Exclusive FullScreen mode. In windowed mode, I still get bad frame drops. Why is that? Maybe SuperSampling does not actually work in Exclusive FullScreen mode???

[huhn]

maybe start with an OSD screen?

That option doesn't seem to change the behaviour. If I untick 'automatically detect black bars', upscaling enhancements work fine with supersampling, clear difference to picture and render times shoot up to around 35ms. As soon as I tick 'automatically detect black bars' render times drop dramatically and the upscaling enhancements 'crispen edges' and 'superres' no longer have an effect, even though the image is still being doubled and then downscaled by setting '2x supersampling' in image doubling.

@iSeries

sound like a bug.

do you have steps to reproduce the issue maybe even from default settings?

i will check it out too.

you can backup your settings file if you don't want to lose your current settings.

I think AB is too strong in the new sxbr options, I'm afraid an additional knob would be very much needed there

I got some 720p videos that give a dark pixelated look when NNEDI3 is used for luma only, I'll try to find what triggers it.

Fair enough, I guess we have a choice between the softer 1D with a higher strength and the sharper 2D with a lower one......at this point it boils down to the sharpness of the source material, how sharp your doubler is, how your display reacts and indeed personal preference. Bicubic also hides defects Jinc makes obvious.

But good point, I'd rather get 1D to work at it seems less demanding and as much as my 7850 can do all I want(FRC/SR/RS/SSIM/NNEDI3) on SD that's a no-go on 720p@1080p so I'm gonna have to either cut corners on doubling or downscaling.

madshi, always appreciate your continued development of madVR.

Considering the tons of options you now offer, I hope that sooner or later, when you reach the 1.0 milestone, you'll create complete and proper documentation for madVR. I know that, personally, that would make me extremely happy about buying a commercial release of it.

Thanks again. Keep up the good work.

I can't, most of my vids are shot in 1080p/60fps. If I even attempt x2 Supersamling I get horrendous frame drops, and I have a Palit 980ti Super Jetstream using just a 1080p monitor.

Same when I try to use Reconstruction for Chrome Upscaling. It takes my GPU usage right up to 100% and drops loads of frames to the point it bogs the PC down.

No problem with 2D content, only with 3D.

Does someone have any idea?

There's been a lack of love for Spline, so I thought I'd add some. At least for much of the stuff I watch, it works well, and doesn't use a lot of power.

It's like a slightly less sharp Lanczos or strong Bicubic, but with fewer artifacts and smoother macroblocking/noise. It uses less power than Jinc. I don't recall as I'm typing this, but I think it's sharper than Jinc. And much sharper than SoftCubic.

It uses noticeably less GPU than Jinc. madVR can do impressive things at full throttle, but it's good to also have settings that don't push the GPU and wattage and heat. Spline uses more power than certain settings, but barely more.

I've been going back and forth between Spline, Bilateral, and Reconstruction Soft for chroma. Bilateral and RS tend to win out, but they're all good.

For cranking up the GPU more but still not wanting to go all out, Super-XBR in the upscaling tabs and in image doubling seems to be great most of the time. Turning on image doubling even with Super-XBR basically doubles my GPU usage, but still uses less than power-hungry NNEID3.

Just adding some Spline love so it hopefully stays around.

i did some test for super xbr anti bloat

super xbr 100: https://www.ezphotoshare.com/images/...3/26/TrPdp.png

super xbr anti bloat is less sharp than spline 3 AR. which makes it really soft for upscaling.
the effect of anti bloat is looks useful. it has an very nice anti ringing effect. is it possible to use it with super xbr 125 or even 150 in the future?

[Anima123]

Where's the anti-bloating option for Super-xBR? I couldn't find one.

[huhn]

it's in the drop down menu.

Yeah I do. Anyways problem went away after a clean install of drivers, so probably not madVR related after all

Sorry for wasting your time, and thanks for the good work

In those examples, I don't really like it. super-xbr should be sharp.

Does super-xbr still ring? If not, then the sharper version would be my preference. I am starting to feel the same way about SuperRes. Unless the bloating is obvious and offensive, anti-bloating will take away too much image detail that should be there. I have three image that show this pretty clearly. I'll post them some time in the next two days.

compared to spline 3 ar and super xbr 100, 100 anti bloat has less ringing. line look simply more natural but it is simply not sharp enough.

and 125 and 150 looks forced. and i see potential for anti bloat here. i hope it is at least as sharp as super xbr 100 but with the anti bloat effect.

Yes, I did notice anti-bloating tames ringing, so it may have its place. Using a higher value of super-xbr may be the ideal combination.

The only complaint I ever had about super-xbr was ringing. When combined with SuperRes, it looks so similar to NNEDI3 in test images. I would guess super-xbr is the most popular algorithm because of its price/performance ratio, so I would support improving it in any way.

I am with you. I don't like AB for super-xbr, it takes away all the sharpness and detail, and you end up with an artificially soft image (fhd->uhd). I don't find it useful for SuperRes either.

Initially I very much liked AS 1 (or 1.5) with AB 100% as an upscaling refinement, but after watching a full movie with it, things looked weirdly off. Too sharp, and too soft at the same time. Not sure how to explain. I am trying SharpenEdges 1.0 with AB 100% to see if that combination makes more sense.

[AngelGraves13]

My new settings are...

Chroma: Super-XBR 150 w/ AR + SR 1
Upscaling: Jinc AR
Downscaling: Jinc AR + AB 150
Image Refinement: SR 1 (every 2X) w/ AR + AB 150

I used Futurama for testing as it's easy to spot the differences in animated content. Lines are sharp and smooth. Thanks madshi!

Also, I find anything higher than 1 for Super Res is pointless and introduces ringing.

I didn't watch an entire movie, but sharpen edges (0.5) with anti-bloating 100% looked like an improvement at 1080p -> 1080p. Removing fat lines is an obvious benefit. Taming oversharpened images also works well. But, it I get the sharpening at an acceptable level where it doesn't look oversharpened, it doesn't seem necessary.
