BluesFanUK, I know, it can be confusing and requires some reading and testing.
Anyway, enhancement seems less resource-hungry than refinement and also is the only option if you want additional sharpening when not upscaling (i.e. 1080p material on 1080p screen). Likewise the new de-ring and the old anti-ringing algorithms are two different things (as has been discussed on previous pages), so they can be used together if needed. Someone else can comment on the particulars of SuperRes but anyway I don't use it on chroma at all because I don't like the additional sharpening effect (I do use AR though with Super-XBR 100, which has a great cost-performance ratio compared to NNEDI3).

Possible bug, "disable calibration controls for this display" still allows use of the enable gamma processing function so it is unclear what the difference would be between disable and "already calibrated".
That said, I observed that brightness 15 appears the same as enable gamma processing pure power curve transfer function 1.95 and brightness 25 is the same as 1.80. |

Hi
Perhaps this is not the first time being discussed but I am curious as to whether I am doing something wrong. I have downloaded a video with hdr, this one in particular: http://demo-uhd3d.com/fiche.php?cat=uhd&id=144 When I use enhanced video renderer it looks fine but when I use madvr it looks wrong: http://imgur.com/XPLQ320 Is there a setting I must change or is this a bug or compatibility issue? I am using mpchc 64 bit and lav filters v0.68.1 and the latest version of madvr (0.90.18) |

I'm guessing you need to adjust the peak luminance value (increase it).

image enhancement is always used. upscale refinement only when image is scaled Quote:
there are exceptions but that's complicated and done to save a lot of performance. Quote:
some filter are better before scaling than after scaling. Quote:
and the anti ringing features for chroma and image scaling are there to remove ringing from scaling or stops them from adding ringing. they are totally different. Quote:

I also tried downloading the latest version of mpchc but this didn't make a difference EDIT: Thanks, this explain it then! Is it possible to force the nits of the file to a custom value? Last edited by phm; 14th May 2016 at 22:23. |

I think what you want is to disable HDR handling for that file instead of overwriting the metadata. That EVR shows the expected image supports this because EVR doesn't support HDR.

Can someone tell me why I can no longer use MadVR in Windows 10 unless I enable DX11? Or rather why it gives a blank screen on default settings. Locks up solid if I try to use Windows overlay and locks up/corrupts when switching between multiple displays??? FSE only works with DX11 too but I tend to have to disable delayed playback.
I asked about this earlier and got NO response whatsoever! I have tried rolling back MadVR, rolling back AMD drivers to Win10 defaults. Various flavors of MPC-HC and setttings. It's only MadVR causing the crashes and not being able to use it like I used to up until the last few weeks. It's got me beat. |

There's a lot of options and you done nothing really other than roll back your drivers. Have you run a SFC? Or tried a system restore? Doesn't sound like it's going to be madVR's problem at all. |

hi~madshi and everyone:
1) I find the issue of 0.90.18 "image doubling activated if the window is smaller than the video" also happened when I play a DVD resolution video. The scale shows "0,0,720,480 -> 0,0,852,480", but the image also unnecessarily doubled "image > super-xbr < Bicubic150 AR". 2) About downscaling, is SSIM 2D 100 the optimal choice ignoring performance? (I'm using Bicubic150 AR now.) 3) I updated from 0.90.10 to 0.90.18, under the same setting, rendering time increases for a few ms. Maybe the reason is: * downscaling anti-ringing filter is now much more aggressive; * added Hyllian's super-xbr anti-ringing (for image doubling); * reworked super-xbr chroma upscaling anti-ringing algorithms; Anyone have the same experience of rendering time with me? 4) I tick the "delay playback start until render queue is full" all the time, but find the queue is not filled when playback start several versions ago(the stutter in playback-start also disappeared compared to very old versions). I don't mind it for the queue will fill quickly until I updated to 0.90.18. Maybe for some reason above, the rendering time comes to a threshold, and the queue struggles and can not fill for 1 or even 2 minutes, during which the dropped frame increases. Does anyone also have this "queue is not filled when playback start" problem or is it a known issue? I have tested on WIN10/XP, D3D11/D3D9, FSE/WINDOWED mode, the problem is the same. Thanks! |

neno,
2) I only use SSIM 2D for UHD -> 1080p downscales. For downscales after doubling/quadrupling, I use SSIM 1D. 2D is more resource hungry/better but I remember madshi saying there's not much (if any?) visible benefit in using 2D for smaller downscales. Anyway, 1D seems to be a little less taxing than Bicubic 150, which is an added bonus. 3) On one of the previous pages madshi confirmed that some (can't remember which) features are more resource hungry now. Also updating to the latest Nvidia drivers cut off a few ms with the previous build for me. There's no escaping regular tweaking... 4) Maybe the queue is struggling to fill up because of increased resource requirements? Has happened to me after madVR updates. Try lowering or disabling some features. |

In any case, when analyzing those 16bit ramps, madVR understands both types of LUTs to be "linear". But when creating a linear 16bit ramp, madVR uses 257. From what I remember, in some OSs and with some GPU drivers, 256 was used and sometimes 257. Quote:

Maybe you could activate supersampling (see image doubling section)? If you do that, upscaling refinement should work as expected. Of course this solution costs quite a bit of extra performance. Quote:

But please try the next build, it has some (smallish) improvements. Maybe it works better for you? It's not perfect, though. And it probably never will. Quote:

The upscaling refinement controls are meant to repair softness that most upscaling algorithms introduce. So these 2 sets of options really have a different purpose, and it may make sense to use both at the same time. That said, this is all a work in progress. I absolutely plan to make the whole settings mess less complicated at some time in the future. Quote:

Issues like this are hard to diagnose from afar. Try reinstalling/updating DirectX. Newer OSs sometimes don't ship with full DX9 support. But the key question is: If this used to work, what has changed to break this? It's almost impossible for me to say with the limited information I have. |

madVR v0.90.19 released
http://madshi.net/madVR.zip Code:
* fixed: image doubling was sometimes activated although it shouldn't * deringing strength was slightly increased * deringing artifacts were slightly reduced * deringing now adds some grain to deringed image areas no deringing - - | - - madVR v0.90.18 - - | - - madVR v0.90.19 |

Unfortunately not. I haven't directly compared it yet, but maybe the old deringing filter even looked better with this particular cartoon even without SuperRes than the new one (which probably is better with filmed content?).
Maybe the grain around the dark lines makes the image look a bit dirty, will do screenshot comparison soon. |

madshi,
Just did a quick test, seems the issue I reported is fixed. It's game 7 for my Raptors and I will be back to watching my shows afterwards and will report any issues, if there are some... But it looks A-Ok after the quick test. QB
