"trade quality for performance" options. This bug can not reproduce by scrshot pic, only when playing video. Any downscale with linear light on and chroma upscale with reconstruction & jinc.

thanks for the new builds, just ran a few tests:
-first time I updated from .4 to .6 I was greeted with major posterizing but I don't seem to be able to reproduce anymore -I don't like the 1.6 gamma thingie as it kills picture depth, I believe I prefer LL enabled but I would need to run more tests -I can't get either SSIM options in .6 to look anywhere near as natural as in .4, I regularly get that stunning "look through a window" feeling with the latter but both options in .6 look way oversharp & aliased(I do run a combination of full SR + NNEDI for luma & RS for chroma so I'm on a tightrope so to speak), one being even worse than the other time for some lighthouse ground truth comparisons I guess? should I use CC AR LL for the original 1080p>720p downscale?

Good to hear.

I guess that's probably not something you like to hear? It does make sense to limit NNEDI3 to be used only for certain upscaling factors, though, especially for chroma (where upscaling quality is much less important than for luma, anyway). E.g. if you upscale chroma by only 5%, using NNEDI3 instead of e.g. Jinc or Lanczos wouldn't really bring any visible benefits. So I gotta define some upscaling factor at which NNEDI3 starts to be used. Quote:

The problem with that is that for downscaling we don't really have an objective groundtruth. You could make comparison screenshots, but with downscaling we're back at subjective "what looks better to your vs my eyes" judgement calls. The only way to judge this objectively would be to display the image in the original resolution on display A, then move display A back until the image has the same size as the downscaled image on display B. Then you can compare whether the downscaled image on display B looks near to the original res image on display A or not. But it will still be difficult to compare because it will be two different focus depths. Should be fixed in the next build. Last edited by madshi; 9th February 2016 at 00:05. |

madVR v0.90.7 released
http://madshi.net/madVR.zip Code:
* fixed: banding when using linear light downscaling (introduced in v0.90.5) * fixed: some problems when moving madVR to a different monitor * fixed: OSD display bug when using different scaling algos for X and Y |

You made clear that soon there will only be one single SSIM button, either of them in .6 are useless to me when .4 looks so great <sigh>. You're the boss and I fullly respect that but how about a "soft" SSIM setting that wouldn't be any sharper than it was in .4 and another one called "sharp"? SSIM is meant to be sharper than CC AR LL but a sharpening downscaler without a single strength knob and when all other options(SR/RS/NNEDI3) are already extremely sharp all together end up next to unusable My point is that bicubic downscaling now comes with as many as six sharpness options so you are effectively allowing us to subjectively pick its sharpness depending on the rest of our post-processing, personal taste and video display but SSIM is meant to go the other way around, with you deciding what looks subjectively best™ to you on your gear and us trying to adapt the rest of our settings to it.....but the only knobs I have access to are SR's and 1 is already VERY sharp for both of them =/ Oh well, talk about a missed opportunity bleh, I'll just bite the bullet and play around with the bicubic sharpness then. A sharper CC AR LL would be right up my alley I guess, hopefully I'll get it to deliver. Last edited by leeperry; 9th February 2016 at 07:19. |

Here is something I don't understand. How do you manage to make sure that >>without clamping<< your RGB (or R'G'B') values are (for example) never negative when they are obtained by a conversion from something like >>destructively compressed<< YCbCr?

Could someone tell me the advantages of turning off 3D in the operating system during playback of 2D or 3D videos?

there is a dude that still thinks his PS4 is the ultimate player for blu ray.
i need to convince him that madvr passes every blu ray player out there for PQ if you starting to make use of the chroma upscaling settings. but of course you need a fast graphics card to get the most out of it. have anyone compared the picture quality from madvr with an PS4? when and with what settings will madvr pass it? it cant be that hard right ? all i know is that i sold my Pioneer BDP-LX58 blu ray player last year after comparing it to madvr. the PS4 must be way behind even that player right?

I've been looking around for a while now but can't find a good answer in regards to madvr, I get quite bad jitter at times with playback even with smoothing enabled, tried reclock and all sorts.
Thinking it might be because GPU limitation, system is running a Intel Pentium g3258 at 4ghz, I do have a gt220 laying around but don't know if it would help. If it's definitely the intel hd graphics limiting my rendering performance then was thinking of getting a gt730 passive (for that sweet silence) Thoughts on this?

I can't imagine that it would be better. There isn't a consumer hardware device available that can best madVR in picture quality or options. For some people a PS4 may be good enough. I wouldn't waste time trying to convince anyone of anything they're not already open to. |

Are the CPU/GPU queues full in madVR's rendering stats (Cntrl + J)? Have you tried a simple audio renderer that is not ReClock? Are the dropped frames and presentation glitches counters staying at zero during playback? If you can answer yes to all of these, it may be your display is at fault or the low frame rate of the content. The GT 730 would allow you to get a lot more out of madVR than integrated graphics. If you can afford it, it would be a wise upgrade.

I reset to defaults and only changed downscale to SSIM detailed and image doubling to quadrupling without touching anything else. It doesn't matter how many neurons are selected, so probably little point in uploading the settings.dat, it can't be related to that. Almost looks like you run out of OSD space when the render steps are shown. http://i.imgur.com/xyzjGlS.jpg I prefer the detail level.. but yes edges do seem a touch over aliased although clean isn't *that* much better. madshi is it possible to slightly lower the sharpness in some way of SSIM so that detailed could be preferred? I like the extra detail throughout the picture but I'm not a huge fan of the extra edge sharpness that comes with it. Last edited by ryrynz; 9th February 2016 at 07:46. |

Windows7 x64 Pro (GeForce GTX 980Ti, 356.04), Zoom Player Max 11.1, latest LAV nightly build and madVR 0.90.7. Using the default d3d9 FSE mode, to reproduce play a DVD and then stop playback (s key), the last frame stays on screen until you exit the player (alt + x). If I enable the option use a seperate device for presentation (Vista and newer) playback works without any problems. Thanks. |

Hi madshi, I have two very similar issues.
1. When I drag mpc-hc window from one display to another the playback pauses and I have to press Play/Pause button twice to resume. It was introduced in the latest .7 version. It happens every time in both D3D9 and D3D11. 2. When the player picks up another file from the playlist and madVR switches to different refresh rate - the playback pauses. What's interesting is that in D3D9 I only need to press Play/Pause once to resume, twice in D3D11. Also, it happens only from time to time, more often in D3D11 than D3D9. This was introduced earlier but I'm not sure in which version exactly. I'm on Windows 10, NVidia GTS 450, driver v361.75. Quote:

Madshi, with 0.90.7, if double a 720p video with NNEDI3 32 then using SSIM for downscaler, the video will be 'greenized' if I didn't use 'double chroma resolution'.
The 'greenized' screen shot: https://www.dropbox.com/s/w4nhags6wh...edPic.png?dl=0 The normal screen shot (not the same frame but it's obvious): https://www.dropbox.com/s/q6o84zhtdl...alPic.png?dl=0 Edit: There's no SuperRes used for both. Super-xBR image doubler does not suffer this issue. Last edited by Anima123; 9th February 2016 at 07:53. |

2. 1.6 linear looks more like Gamma light to me. I prefer the look of 2.2 linear. For the past few years, Catmull Rom AR LL (with 2.2 gamma) has been considered as the best downscaling setting. I would suggest to not replace the 2.2 gamma with 1.6 gamma LL, so that one can always go back to CR AR 2.2LL. Quote:

Well, I seem to like the previous downscaling method especially for 4k to FHD when the chroma was upscaled to 4k and then image was downscaled to FHD. I think the supersampling effect on chroma affects the perception of depth in the images. I am not sure if this can be shown through screenshots. Anyway, I would prefer if you could add a trade quality option to restore the previous downscaling method. |

the trick is to assume the gamma is 2.2 and to change it to 2.4 for a bat cave to get the "correct" gamma of 2.4. because the mastering lightning and the viewing lightning is totally different. so i have no clue why video should be 2.2 while film should be 2.4. at this moment it is assumed the source is gamma 2.2 and altered to 2.4 so if the source was 2.4 in the first place we wouldn't get gamma 2.4 with our gamma 2.4 3D LUTs. the same reason "color & gamma" is increasing the gamma when set to 2.4. because it doesn't know the 3d LUT is already 2.4. |
