super-xbr vs NNEDI3
@madshi, is there a way to compare super-xbr to NNEDI3 settings? Like super-xbr 100 gives the same image quality as NNEDI3 *** neurons?
It would be really nice to have some sort av list that compares the different settings, so people could have a general template to aim for according to the hardware capabilities their computers have.

Where is image enhancing heading? Is anti-aliasing a thing of the past? What I'm saying is as resolution increases the requirements to achieve the best image change when upscaling. If your gaming in a 4k resolution on a 55inch screen is enabling any form of anti-aliasing simply putting uneeded work on the GPU for example? Of course upscaling is a little different but if your upscaling from say 720p to 1080p I feel using the same algo to upscale from 720p to 4k may not give the best result as using a different algo because of our eyes and the target resolution.
For me its all getting quite blurry in the gain some of these algos really bring. Probably mainly because I dont have the best eyesight in the world to be able to see the difference when sitting down to actually watch something at a normal viewing distance. On top of that of course not all content is the same. But I do wonder if it is getting into the realm now where it should be possible for a renderer to look at the source resolution, destination resolution, and color spec. Then examine key frames in the movie and automatically pick the best scaling algo? For me personally I would enable such an option. Even if it required me waiting a minute for a movie to start while madVR calculated the best scaling based on the source material and output resolution etc, I think it would be worth it. I guess a good start to that would be for a renderer to try a detect if the source material is a movie or animation by simply looking at frames of the source material only.

I suspect it's likely not worth the effort to have preset profiles determined by graphics card power, while this has been mentioned a few times I don't think it will happen. Plenty of guides online give you opinions on what to set based on general opinion, you just need to put some time and effort in to following them and determining what you think suits your display, taste & content.

Hi guys,
Really need your help here since I've done all possible things to solve the issue but to no avail. My sytem chain: - TV: Philips 32PFL9632, only accepts 60Hz resolution for PC input, - HTPC: Win 10 x64, GTX 960 4GB, Intel Core I5 3470s, 8GB DDR3 1600, Intel SSD 128Gb - Software: MPC-HC x64 nightly 207, LAV Filter 0.68.1, madVR 0.90.19, SVP 4 Pro As stated above I'm using SVP to interpolate frames to 59.94 for my Blu-Ray rips 23.976 done with eac3to (thanks madshi for another great tool!). In madVR display modes I have input 1080p60, 1080p59 just to be sure. However madVR stats reports display at 59.93760 which is close to 59.94 but not a perfect match (I have another HTPC with an Intel HD4400 and I'm able to achieve 59.94006).I'm guessing this is the reason why I'm seeing "1 frame drop every 19.48 minutes", because otherwise rendering and present stats are more than ok and my rig should be more than capable to handle my madVR settings (chroma-up: Bicubic75AR, image-up: Lanczos 3 Taps + AR, downscalling: SSIM 1D, no doubling, ordered dithering, use D3D11, enable automatic fullscreen, everything unchecked in trade quality for performance). I've also tried to create a custom resolution with NVidia Control Panel of exact 59.94 but it seems that my TV is rejecting it, madVR starts showing 59.94 for 1 sec and than immediately switch back to 59.937 and sometime crashes. Is there anything I can do about it? Is it my TV that only accept a fixed resolution, my NVidia which cannot produce a more accurate 59.94 or both? I have also attached an image with madVR stats in full screen taken with my phone, sorry for the resolution. http://i.imgur.com/IGVLpJS.jpg The image is taken immediately after the movie started and I reset the initial dropped frames but I have also tested the movie for 1 hr and indeed after 20 minutes or so it started to dropped frames 15, 24, etc. Thanks a lot in advance for any help. |

However, having an algorithm pick optimal madVR settings is a far future concept. We don't even have a good way to measure video quality mathematically. Quote:
I suspect madVR interacting with SVP. Those are pretty light settings, is the GPU downclocking after a while? "All possible things" rules out pretty much everything we could suggest... What have you tried?

- custom resolution NVidia / not working on my TV - starts with 59.94 but reverts immediately to 59.937 - lowered the settings in madVR to bare minimum / nothing changed - on x86 chain I have 1 frame drop every 4.xy hours but only with ReClock / obviously not possible in x64 - checked on another system but with Intel HD4400 and there I can get very close to 59.94 --> 59.94006 / probably NVidia 60Hz resolution is in fact fixed at 59.937 ? I do not know what else to try, but again my knowledge is limited and something escapes me ... or as you suggested maybe could be SVP linked meaning that probably I should interpolate to screen rate (much heavier on resources since more calculations needs to be done) instead of a fixed default 59.94 ... Downclocking should be spotted with GPU-Z no? I can watch that to see if it's the case. Any suggestions on what else I should check? |

I know about smooth motion but that is frame blending and not frame interpolation. I kinda like SVP effect but this is a matter of taste. My question towards more skilled people here is how close NVidia can be to 59.94? Because for me is 59.937. If I force everything at 1080p60 only in madVR I get 59.974 so I'm either below or above the target of 59.94. With Intel HD4400 I'm close to perfection 59.94006. |

Although reclock will make madvr report a better framedrop interval the value reported by madVR becomes invalid because reclock is constantly adjusting the audio so the framedrop never actually happens. Pity you are using x64, I keep 32bit just for reclock.

Hi madshi,
First of all thanks for all the good work But could you please fix the bug with italic subs that breaks the 'move subs to bottom of the screen' option? It's the only issue I have with MadVR after months of use Cheers |

if you want to stop repeating/dropping frames you have to match the audio clock. the reason why intel has a "perfect" clock comes most likely from sharing the system clock with the video clock so they may have the same clock generator. in the end it doesn't matter if the audio clock is different. there are 3 clock in a system (maybe a lot more). the system clock, the video clock and the audio clock. the system clock is not really important in this case. the clock deviation in madVR is important not the shown HZ. |

Damn, the new De-Ringer is quite heavy on my GPU. I had to lower SuperRes to 1 in both Image Refinement and in Chroma Upscaling for 21:9 content when using NNEDI3 Image Doubling. Still, I think it is worth it. I assume these specific ringing stuff in mostly in older films that were upscaled from SD to HD?

Are there any other methods except ReClock that would allow me to match the audio clock and still use everything in x64? |

madVR smoothmotion will take care of this too. the sanear audio renderer has a planned feature like reclock. |
