Ok, here's one last build, after this I'll probably not have time to do madVR development for 2-3 days. So there will probably be no more test builds in the next 2-3 days at least.
http://madshi.net/madVRadaptive4.rar This build is a slight modification of the A1 build, in the same way that A3 was a slight modification of the A2 build. So basically A1 -> A4. And A2 -> A3. For the scientific crowd: The modification is that I'm applying a minimum random factor of 0.625f (identical to NL6). The max random factor is 1.0f, and depends on the exact gray level. The difference between A1/4 vs. A2/3 is that the exact random factor is calculated differently. I think that A3/4 should hopefully combine the positive aspects of NL6 with the adaptive approach. At least I hope so. Whether A3 or A4 is better might be a matter of taste. I think A3 has a slightly more random look. Which could be positive or negative, depending on taste.

Adaptive 3 looks really good. Seems to maintain rich deep colors with good blacks and shadow detail. Clarity/realism is amazing.
Needi3 64 with doubling set to 32/16 always with lancos4 and jinc3. No problem running 720p/1080p movies. All quality settings unticked. Thanks everyone looks better everyday. Sent from my iPhone using Tapatalk

Mathias: I am pretty sure I have shown these schemes to you before. The "new" thing (hopefully) is pointing out they are reasonably antialiased for pixel art type objects given how sharp they are. I am not suggesting that they be used for upsampling "standard" video content: Jinc3 AR is about as good as this family of schemes gets.

I would like to verify a MadVR setting for viewing the various MadVR*.ax variants. It's been mentioned that dithering should be disabled in MadVR however I see no such setting. Under "Trade quality for performance" I can either select use random dithering.. or not. In that case OpenCL error diffusion has been selected. If so then "Use random dithering instead of OpenCL error diffusion" should not be selected. Correct?

A1 felt a bit like unfinished business, I mean there was less noise but it still felt a bit out of control. With A4, the sensation of depth is back with a vengeance, there's even less noise visible and the picture is much clearer. You are setting new benchmarks everytime, GG so how am I gonna live without my daily drastic PQ improvement then? Last edited by leeperry; 16th February 2014 at 23:38. |

If you disable OpenCL dithering in the various MadVR*.ax variants than there is no point to using the variants. We are testing different dithering techniques. To test the various new dithering methods UNcheck all dither related "Trade quality for performance" options. Quote:

I will have to back leeperry for my vote when deciding on which adaptive build to go for. Last edited by Asmodian; 17th February 2014 at 05:22. |

Sorry if this question has been asked before. If you're using LAV decoder are you using Ordered Dithering or Random Dithering? I.e. is random dithering redundant and just raising the noise floor or is it dithering something else?

madr supports ll colorspaces lv can output and this option is only used when a yCbCr colorspace is change to rgb and this is not going to happen. except you are playing around with settings just leave it as it is and it fine and not used. |

A4 looks good in terms of randomness but its also the brightest and has the most abrupt transition to black.
A1 looks good but it lacks dithering in the darkest shades, good gamma curve. A2 It has the smoothest transition between shades and looks like A1 in terms of gamma. A3 is a tad brighter than A2. A4 is even brighter than A3, but it also fixes A1 "holes" lack of dithering. For me its still A2. P.S The Adaptive builds are a HUGE improvement over the NL builds (from what I see).

Comparison of all the NL1-8 and AD1-4, Grey & Color: ED Builds Test.zip
* Ver Greeneyes's 16-bit videos are used (Color & Grey). * Organized in folders according to frame. * "NL Tests" are frame 88 of Color. IMO, You should look for smoothness in transition and no abrupt changes or big brightness (gamma) changes. Also, the dithering pattern should look even and without "holes"** in the dithering pattern. **(I'm not talking about the undithered places which should be undithered). Now more than 3 people can decide the future of MadVR.

At this point, I'll only say that the A4 is a major improvement over the A1 build on linear gradients. I won't know my preference among all the adaptive builds, until I expand my tests to examine the dithering behavior on real-world videos.

Bottom Line is that I have spent the whole day attempting to find a combination which yields screen shots demonstrating the effects of the various MadVR*.ax files and have not succeeded. In the past simply deselecting random dithering, capturing the screen with MadVR or Printscreen has worked. Now for an unknown reason(s) no combination of NV12, YV12, adaptive4, linearlight, MadVR image capture or printscreen (with and without FSE) shows any indication that dithering (error diffusion) is changing. Based on past experience with the MP4-2c gray scale-ramps and test files provided here they have never looked better - while utilizing whatever method they are using (or not) Shared folder @Mediafire I'm stumped and this doesn't happen all that often when it comes to 'pixel peeping'. I'm open to all specific suggestions relating to MadVR/LAV settings (I disabled ffdshow and associated AVIsynth scripts right up front). |

MistahBonzai,
Everything is fine, ED is changing. The difference is so refined between the latest builds, that its almost invisible with the naked eye (without software intervention). Its not the big difference we had between, DC3, Noisy & NL builds. We are at the top of the pyramid (so to speak) now.

All I'm saying is that subjective contrast is amazing with A4(Oblivion looks so darn good, yay!) so this might very well match your findings, 0.2 cents territory here so don't throw rocks at me just yet Quote:

Subjective contrast can mean Enhanced Contrast and that's not a good thing for video purists or what MadVR is trying to achieve. I think we should go for accuracy instead of subjective perception. What do you think? Quote:
You seem to be the only one... On my hardware calibrated (i1 Display Pro) monitor, I can't see the difference with my naked eyes. On what hardware do you compare the builds? Are you sure your TV/Monitor doesn't do some funky enhancements or something? Maybe you have the Brightness (TV) set too high so you can clearly see what supposed to be very dark (where the dithering is most prominent)? Wait, don't tell me you're sitting a foot from a 100" TV?
