So I shouldn't be downscaling in linear light if using Spline? |

imho one shouldn't use it at all. There's a reason why usually gamma corrected is considered as the desired result (or better said: gamma correction gives the desired result in the end).
I just played some desktop capture videos and fonts look totally awful with linear light downscaling. |

You should be using photographs or movies. Something that was filmed instead of rendered. With that, linear light downscaling should be better - at least if your display is properly calibrated. http://forum.doom9.org/showpost.php?...ostcount=25427 (note: this is a macro image of a fly) View the comparison images here at 100% in your browser and switch tabs. The image scaled in linear light should look very close to the source, only lower resolution. The image without linear light scaling is quite a bit darker than the source image, and finer details are lost. Quote:
I don't recommend enabling the linear light scaling option with anything else. An old example comparing Catmull-Rom and Lanczos. |

It introduces tons of aliasing. It would be better if the source's resolution would be high enough to have a realistic result in a common native resolution. |

Though fine details are better preserved by using linear light scaling, it is the overall brightness/appearance of the image which is important. Linear light scaling preserves the "silvery" appearance of the eyes, while scaling without that option shifts the tone more towards brown. If you wear glasses, you may even want to take them off when comparing the three if you find the aliasing distracting. Resolution should not be a factor in this comparison. And please ensure that the images are not being scaled at all, they must be displayed at 100% size. |

In general, is there a consent on using higher needi3 neurons vs using SuperRes/ more pass SuperRes?
I have some 480p DVD that is like 0.5% of the content I watch, but I really like those~. My eye test seem to favor more neuron(32->64) compare than more pass, or even activating SR, but then there is the pixel shift which make the comparison kind of weird/hard ?

The effect of SuperRes with madVR is not exactly the same as the one with MPDN for some reason, I don't know why.
I'd prefer the MPDN version, quality speaking. Maybe madshi have some idea to tweak the SuperRes a little bit, or there's some kind of bug when SuperRes and NEDI were included within madVR? |

Does this problem only occur with PotPlayer? Or also with e.g. MPC-HC? I think there is a setting in PotPlayer which causes madVR to rerender frames all the time in paused state, causing rather high GPU consumption in paused state. I'm not very familiar with PotPlayer, though. If you disable that feature (in case you know which it is), does that make the problem go away? Quote:

That said, yes, maybe Shiandow's debanding algorithm could be used as a starting point for a new deblocking algorithm. But there's no room in my time schedule at least for that anytime soon. Quote:

http://madshi.net/madVR8810test5.rar Please activate debug mode first (by double clicking "activate debug mode.bat"), then afterwards drop in the new madVR.ax. If you do it the other way round, but you're replacing the "wrong" madVR.ax file and you're testing with the official v0.88.10 again. I know, it's a bit confusing. Basically, after you dropped the replacement madVR.ax file into the madVR folder, don't double click any batch files, until you've completed testing. Thanks! |

Hi madshi.
I have question for you. How you(what API function use) change resolution/refresh rate ?? In MPC-BE/MPC-HC use ChangeDisplaySettingsEx(). But - after buy new GTX 960 i have some trouble with 24fps mode - after use ChangeDisplaySettingsEx() my TV info that use 24p, but in MPC-BE EVR Custom i see that fps ~23.976(and it's true). If i try use madVR with auto-refresh - i give "true" 24p mode. You do not know what could be wrong ??

Call ChangeDisplaySettingsEx with the new mode and CDS_UPDATEREGISTRY | CDS_NORESET once, and then a second time without a new mode and without the flags (it'll use the new mode you set in the previous call then)

It's not necessary. Even call ChangeDisplaySettingsEx() only with CDS_UPDATEREGISTRY or CDS_FULLSCREEN or 0 - it's work. But something wrong with new mode - TV info that 24p, but in fact - 23.976. All other mode working as it should.

nevcairiel has it right. If you use ChangeDisplaySettingsEx() the normal way, it will switch to 23.976, even if you specify 24.000. You have to call ChangeDisplaySettingsEx() twice, in a very specific way (see nevcairiel's post), to get true 24.000. |

Since the last 2 versions (0.88.9/0.88.10) if I set debanding as high it drops a lot of frames, I'm using 0.88.8 and it plays fine, my graphic card isn't good at all (GT 610), but I can play 720p files fine. This seems to happen since high debanding was modified, can I get a version with all the new changes but without this change specifically?

New versions enabled gradient analyzing for "high" debanding. Go "rendering"->"trade quality for performance" and tick "don't analyze gradient angles for debanding". Then test again. (I don't know if it really needs much performance. Maybe it's just a coincidence and real problem is something else?)
That said, debanding might change again in the very near future according to the user reports here so this might only be a temporary option. Last edited by sneaker_ger; 2nd June 2015 at 16:24. |
