Madshi, I was looking over your anti-ringing thread because of Sp00kyFox's enquiry about the availability of your anti-ringing algo and noticed Tritical mentioning NNEDI4.
Did you ever evaluate it? I'd be interested in seeing the results of the modified prescreener. I guess it be fairly trivial to add given there's no major changes to NNEDI3. Tritical preferred the results of his newer version. Never mind, I see he never released it. Last edited by ryrynz; 4th December 2016 at 06:07. |

I'm not a fan of bicubic. I like "soft" downscaling, but it seems you're going for a sharp downscaler with aliasing which then requires softening of edges. I guess everyone has their own taste.
Maybe for downscaling from NGU, you can add a "Soft" option which uses Jinc or something similar. |

All these years with the "Judge it with your own eyes" isn't compatible with what looks like "Don't worry about your eyes, I already did the judging". Sane defaults produce indefinite value to any software, but they can't replace my individual preferences, that I have picked up over the years. If you wish to tone down the settings, fine. Please just let us keep the advanced version of madVR in some form. I would be fine with hidden advanced settings ala ShowRenderSteps. Without it you could present as simplified UI as you like. With it you would get the current one. It would require the user to come out and seek knowledge before they could start poking with the settings. I don't think the developer has any more responsibility to protect the user from themselves, if they wish to use some sort of harmful settings. I would even rather have no UI for these advanced settings and use a plain text config file, than not have these advanced settings at all. What sort of UI you decide to use in madVR 1.0 is up to you. I trust that you figure it all out by then. I just don't want to wait until madVR 1.0 to get the advanced settings back. -EDIT: One idea for making madVR more newbie friendly: Tooltips. They are great for giving concentrated information for a new user without blowing up the UI. There is a currently a huge cliff between blindly staring at the settings with no explanation and googling a Madvr-guide. And trying to judge which guide to choose and trust. Or starting to browse a 2000 page thread on doom9 for information with even more opinions to choose from. -EDIT2:More random thoughts for more newbie friendly madVR: Easy mode (=No learning required) Few presets (~3?) to choose from. Nothing to learn, nothing to ask. Services new users. Completely NGU-based + performance option(s) for when NGU won't do. Advanced mode (=Current mode) What's new? Well, it's hidden, for starters. You can't stab yourself with a knife you can't find. Trying to make learning madVR easy, instead of taking out the need to learn. -tooltips. Provides information without ever leaving the madVR UI. Possibly clickable, taking you to madVR Options Explained or equivalent. -About madVR-tab: Clickable links to officially sanctioned (not necessarily made my madshi)documentation. *madVR Options Explained *madVR guide *madVR bug tracker *this thread *wiki (to be written, by users, to users) *button for activating profiles with a few premade ones (SD/720p/1080p) Last edited by wiFFy; 4th December 2016 at 01:15. |

It's soft because it has no aliasing and minimal ringing. It doesn't need a lot of adjustments. And no, I don't think anyone here would consider Jinc to be sharp.

Madshi
Experimented with NGU Med in chroma upscaling in 422 video. It took twice the processing power compared to 420. Is this expected? Big jump! Sent from my iPhone using Tapatalk

Serious question... what type of video content are some of you guys using where you see such a difference between the different chroma algorithms?
I see zero difference between Bicubic 60AR and NGU Very High. I don't even know what I'm supposed to be looking for because the picture doesn't change at all. IMO it's a complete waste of gpu resources and I just use Bicubic 60AR on everything. Pretty sure madshi has said the same thing before. I just don't get it because I don't see any difference (unlike with luma upscaling where the difference is obvious). Is there only a difference when you zoom in 1000%? If so, then it's just placebo and who cares? |

Well on my very old Plasma ("720p" which is 1024x768 rectangular pixels) different chroma algo's produce very noticeable differences in image sharpness and clarity. I like a sharp image and I can clearly see the difference between NNEDI3 32 and NNDEI3 64 in chroma upscaling... The chroma in image doubling is also noticeable, but to a lesser extant. Bicubic 60 in this context is far to soft. I don't know if it is a Plasma thing, or a rectangular pixel thing, but either way, control of chroma algo's is very important to me.

DX11 crash & 80070005 error
I recently updated both MadVR and Nvidia drivers to v0.91.3 and v376.09 respectively. It's brought about 2 issues. The first is the media player crashes if DX11 is used, and the second is the error - creating Direct3D device failed (80070005).
The 80070005 error only affects a small % of files. All my videos are 1080p mkv (AVC). Initially I thought it might be related to frame rate, but I found some that have the same 25fps frame rate and they work fine. I noticed a while ago that these videos that are now freezing take @7 seconds to render an image and begin playing. I completely reset MadVR, to no avail. I did eventually manage to stop the error by enabling 'Use a separate device for presentation'. I never had to do this before though. Since it's not a crash I can't send you a bug report. I tried ctrl+alt+shift+pause break as suggested when someone else had the same error in 2012, but nothing happens and I can't see a log. Let me know what you need me to do to help you. |

Nothing touches Recon-Soft+chroma SR@2 on my 3500:1 AMVA UE32F5000@60Hz with BFI enabled and FRC in mVR from a 80 cm viewing distance, I mostly use 24p Hollywood movies and picture looks much more natural such as faces or landscapes. Last time I checked worst offender to my eyes was NNEDI3 for chroma, picture looked digital and artificial as can be.

I've done the comparisons myself and the pixel changes are.. basically impossible to notice. Please send me five samples of your favorite content, whatever you like, I'll upscale a number of shots and we'll put your world class sight and equipment to the test. As a plasma owner, it's actually harder to differentiate the differences due to the pixel noise. Last edited by ryrynz; 4th December 2016 at 09:20. |

It's an odd one. Things are fine so long as 'use a separate device for presentation' is checked. I still get an initial delay of @7 seconds before playback, but that's been the case for a while. It's only with specific rips, so I may not have noticed it for a while if not for these few. I checked my Sonarr history and it's a group and source I don't recall grabbing before. Humans.S02E01.PROPER.1080p.AMZN.WEBRip.DD2.0.x264-KiNGS. Since I've found a workaround this is mostly for Madshis' benefit if it's of consequence to him. I am curious to know the reason though. It's a shame MadVR doesn't crash so I can just send a report. I sent one a long time ago and he was really helpful. He seems to properly care about MadVR. I respect that. |

Generally, NGU handles soft images fine. However, blocking artifacts and especially mosquito noise throws it off. Quote:

Probably caused by the driver upgrade. Maybe you can downgrade the driver? |

madVR v0.91.4 released
http://madshi.net/madVR.zip Code:
* redesigned "image upscaling" settings page once more * super-xbr image doubling is available again * fixed: downscaling anti-ringing checkbox was sometimes disabled I've dropped the option to let you choose with which exact scaling factor doubling gets activated. madVR now makes that decision itself. For NGU, doubling is activated as soon as any upscaling is needed, because NGU has some nice properties (e.g. removes ringing) which can be beneficial even when upscaling only by a very small factor. NNEDI3 and super-xbr are only activated if the scaling factor is 1.2x or higher. Of course you can use profiles to force any doubler to activate or deactivate in specific situations. If you've selected any of the doublers and they don't get activated, madVR now falls back to JincAR upscaling. |

I wonder, when does the "<-- upscaling" option for NGU apply?
As far as I understand, NGU doubling is now always enabled when upscaling is needed (even for small factors). So, when upscaling is needed, we always get NGU doubling, possibly (usually) followed by "<-- downscaling". But in what case is NGU "<-- upscaling" used?
