and in the end the file should run without black boarder detection. for a simple reason what if the file stops using black boarders? that's why i would never recommend someone to use that potential extra processing power that is available when black border detection is cropping the image. |

Usual story that SR@1 is already very sharp so the goal would be to benefit from SSIM without the utter sharpness that comes with 25% in order to make the picture look more detailed than CR AR LL and yet not that sharp. I would myself either need softer SR strengths and/or softer SSIM. Last edited by leeperry; 27th February 2016 at 13:26. |

3) I prefer LL enabled with crispen edges. Previously too, I preferred finesharp with LL enabled before the LL option was dropped. Have you tested Jinc downscaling? I would be interested to know your observations about Catmull Rom vs Jinc vs SSIM downscaling. |

I'll have to check with diffrent types of movies to see if I can notice a difference with LL on or off. So far, I don't see a difference if it's on or off. Regardless of LL, madVR enchancements are making the horrid bluray transfer of Face/Off (1997) look better than a VHS upscale. Once I get coffee going, I'll run some quick tests between the two to see if I see any real world differences.

hi madshi
I'm experiencing an annoying bug with the latest version of madVR (MPC-HC.1.7.10.101.x86.VS2015 + MADV 0.90.12) to reproduce the problem starting with the defaults settings (DX9 fullscreen exclusive) you have to set image double and SSIM1D + antiringing as downscaler then closing mpc with ctrl+c the program remains frozen and then I can just reboot my system I tried on two pc with nvidia and amd and I have the same result so I think that system configuration isn't so important it not happens with dx11 fullscreen exclusive, using SSIM1D without AR, or using any others downscaler with or without AR |

When looking at very detailed/busy images, I'd almost say that you're best to use SoftCubic if your priority is to eliminate aliasing because it basically acts as a low-pass filter for the video. I've had a quick look over the sharpening tools and it seems that you can then sharpen this result to bring back some of the detail without introducing aliasing. However, with a focus on sharpening tools for upscaling and SSIM for downscaling to make the image look very "detailed", I'm guessing that this is not the look most people want. I know that I was very unhappy with how strongly low-pass filtered and then oversharpened so many DVD releases were for example - though you can avoid the over-sharpening with madVR. If you want that pixel-level detail which looks good in a static image, you're going to see aliasing when it moves in a video. You can't really get around that fact. Here's an example from Oblivion which I think shows this off reasonably well. (note: my testing was at 50% scale) Looking at the top-down shot at the chapter marker, if you compare SSIM at 25% to something like SoftCubic80+Sharpen Edges 0.5+Enhance Detail 1.5, there is dramatically lower aliasing in motion with the latter. Of course the image is also lacking that really sharp and detailed look because the high frequency detail has been filtered out. To be clear, those settings are not a recommendation for anyone, just a quick example of what I mean about the balance between aliasing/detail and the need for low-pass filtering (or similar) if you want to eliminate aliasing. I'm not saying that there's anything wrong with SSIM or preferring that image though - it looks good for what it's trying to do, and for the type of content that I actually watch downscaled, it's very possible that I'll switch from Catmull-Rom over to SSIM. I've had a look at the anti-ringing filter using proper test patterns now (such as a high-res star chart) and I'd say that anti-ringing looks great for the cubic scalers. It maybe adds a tiny bit of roughness at the very high frequency details, and Bicubic >60 could look a bit better, but I'd also not be recommending that people use the higher levels of Bicubic anyway. For Lanczos/Spline/Jinc, it could stand to be a little bit more aggressive with linear light enabled. There are still some remnants of the dark ringing that you get with LL downscaling at some angles - though I never found it to be a problem with video. With SSIM, anti-ringing is actually adding aliasing at all levels so that probably needs looked at. I thought I had seen this to some degree with some video clips, but assumed it was just because SSIM was so sharp - which was why I wondered if something like 10% SSIM might be an option. Quote:

I did some tests when it was first introduced but my issue with sharpening has always been that it's not something I would ever want to apply globally. It can help a bad source if you're tweaking it to be specific for that source, but always hurts a good source in my opinion. And generally I find that a disc is either well mastered, or if it's not then it probably has a ton of sharpening already encoded in the video. There aren't many films in my library which just have a soft image. If it was like debanding where I could hit a key to either toggle it on/off or perhaps switch between say three separate sharpening profiles I might be more inclined to use it. That's not a feature request though, as I just don't think that sharpening is something I'd use much even if that were an option. Quote:
At the same time, it's possible that SSIM just isn't what I'm looking for, so I may just be better off using another scaling algorithm instead of a reduced-strength SSIM. Quote:
I'd like to see examples if anyone has found cases where Jinc has made a difference though. |

Anyway, whether it makes sense to setup a special profile to make use of the saved power is a question I don't want to answer. If all else fails, at least the GPU will consume less power, which is better for the environment, for your power bill and for fan noise. Quote:

I've been able to reproduce that somewhat with your star test pattern. Have added that to my to do list for maybe next weekend. My question was not about performance but about image quality. This all heavily depends on which frame rate the decoder/splitter reports to madVR. Usually this is out of my control. madVR makes its refresh rate decisions based on that information. |

madVR v0.90.13 released
http://madshi.net/madVR.zip Code:
* added support for finding the right 3D depth for the active subtitle track * added "use alternative glitch handling mode" option for D3D11 presentation * added a workaround for glitch problems with shaky 3D GPU drivers * fixed: downscaling sometimes crashed, when not using SSIM * fixed: Intel GPU always used DXVA scaling when DXVA deint/decode was active * fixed: SSIM AR eventually left some resources open |

This should be left on the first page as all Optimus laptops will have problems with mpc-hc + madVR.
The solution is quite simple. First, you have to go to where mpc-hc is installed for example C:\Program Files (x86)\MPC-HC and rename your mpc-hc.exe to mpc-hc1.exe. After this you have to go to Nvidia control panel -> Manage 3D settings -> Add, then browse to C:\Program Files (x86)\MPC-HC\mpc-hc1.exe and set to to use High performance Nvidia Processor. I will add photos in here. https://www.dropbox.com/s/khfwwz86cwf3k6v/12.png?dl=0 https://www.dropbox.com/s/7rrf8thbdjnwx9k/10.png?dl=0 https://www.dropbox.com/s/oog8l8150u47uti/11.png?dl=0 This should do the trick. If power is anywhere under maximum performance, I experience -drops in performance. I am running an Acer VN7-791G with GTX860M and the latest Nvidia driver, 361.91.

With the AR filter from Refinements + Crispen Edges, I was able to detect a difference, and it was an improvement. Very subtle in my test though. Edit: I'll have to take back what I said about Crispen edges and linear light. Depending on SR strength, I do see a difference and prefer it to be on with SuperSampling up until I hit SR4.

This has probably been asked before, but i couldnt find the answer.
When choosing super-xbr for chroma, why dont the sliders move when applying AR or choosing different sharpness? Do the changes have effect or dont they? |

In my experience, there was at least one movie ("Gone Girl", 2014) that is 2,35:1 but switching for a couple of secs to 16:9. If set to crop black borders, madVR would simply cut such "non-standard" frames to 2,35:1 (unfortunately I don't have this movie anymore so I can't check myself)?

As I said before, they're massively improved now - to the point that people should be able to use linear light downscaling with any of them based on their preference. |

I've only used crispen edges. The new anti-ringing may be a small improvement with a slight decrease in performance. But I wasn't overly bothered by crispen edges before. I haven't checked sharpen edges.
I don't see any improvement using linear light.

I was browing this: Dolby Vision Whitepaper.
I am wondering what the CPU/GPU cost is of decoding the enhancement/HDR layer (HDR10)? My system can't handle high-bitrate HEVC, so it is difficult to tell what is going on.
