I'm not sure any type of generated scanlines (like done in emulators) would be wanted in madVR unless there is video content out there that would look better on an old Low Khz arcade game type monitor than todays panels. Last edited by Razoola; 29th October 2017 at 19:03. |

Concerning "reduce random noise", strength 1 is a good choice now if you want to remove a little bit the noise without the details destruction of higher strengths. But it's still not my cup of tea, too much details are blurred during the process. RRN off vs RRN 1 Look at the writing on the sheet of paper. I suppose there's nothing you can do with this type of algo. I hope that someday you will bring multi-frame noise filter, that would be awesome Quote:
Terraria TowerFall Ascension Hyper Light Drifter Shovel Knight I could show you a lot more videogames like that, that's just some examples. Their aliased look are clearly made on purpose and any upscalings other than Nearest-Neighbor alters the developper's intention. I'm a big fan of NGU for movies and animes but I will never use any "real" upscaling on pixel arts. I hate what they do on this type of content. I hope that someday you will bring back Nearest-Neighbor into the GUI, it's the way these games are meant to be played and obviously watched.

so let's compare lanczos with NGU sharp. while NGU sharp is i guess generally better than lanczos is looks like it is getting out of focus because soem part get really sharp and other not. so i'm just choicing an lesser evil that's not a general increase in image quality in my book. do the good out weight the bads i'm pretty sure it is still just a trade in my book. i was just disagreeing that upscaling is generally better. i have to upscale it anyway so... |

Well, you probably won't want to constantly use nearest neighbor upscaling, so using a keyboard shortcut to activate it on demand should do the trick, shouldn't it? Quote:

Maybe I didn't explain well. In order to shoot the "unscaled" image, I displayed your DVD image in MPC-HC with 100% view (called "normal size" in MPC-HC, resulting in 1024x576), using a display mode which matches the physical resolution of my LCD monitor. So every DVD pixel was displayed by one LCD pixel. Well, not really, because of Aspect Ratio correction. But if we ignore AR correction, it was a 1:1 pixel match. Then I took my digicam, used optical (!) zoom to shoot the image. So (other than AR correction) no digital zoom/scaling was applied by anyone. Not by madVR, not by the display, not by the digicam, not by the photo editor, by no one. In order to shoot the "upscaled" image I simply switched MPC-HC from "normal size" to "touch from inside", changed the optical zoom in my digicam and shot the image again. This way we have 2 images which very fairly compare unscaled vs upscaled, using the optical zoom in my digicam to get the same viewing angle. Got it? Apart from AR correction, we absolutely can do it properly. See above. Quote:

madVR Stats issue
After applying the Windows 10 Fall Creators Update 1709, madVR display rate switching appears to be working with MPC-HC 1.7.13 64 bit, but stats appear to indicate an incorrect refresh rate. For example 23.976 fps source material is showing a refresh rate of 29.97. I have the same issue with both madVR v91.11 and v92.8.
Can someone point me to what is causing this, and suggest a solution? I haven't seen anything obviously wrong in the madVR setup. Display rate switching is set for 1920x1080 resolution. TIA. Edit: The issue appears to be a result of Intel HD Graphics Iris 640 driver v4749 installed by Microsoft's implementation of the Windows 10 Fall Creators Update 1709. While at some point this driver version may have been available for download from Intel I could find no trace of it there today. Reverting to an earlier driver version that I knew was working well with Windows 10 v1703 has resolved the stats issue. N.B. from what I could establish from the Intel HD Graphics control panel the madVR refresh rate switching was working correctly with the Iris 640 driver v4749, and it was the stats display that was not.

Gimme a Spatial-Temporal Denoiser though and I'm all over it because those results are godly. |

I did a fresh windows install but i still have some problems.
Using the option "Use D3D11..." solves the black screen, but when i leave fullscreen the player just shows the last image before it went fullscreen, but the audio is still playing. Also when i hover the mouse on the seek bar the video starts dropping frames. Is there a solution or any setting to solve this? EDIT: Did some testing here. When i put mouse pointer at seek bar on fullscreen the present queue goes from 6-7/8 to 1-2/2, there is no dropped frames on stats but the video is clearly stuttering. Also when i disable switch to matching display mode, the video plays normally on fullscreen or windowed, but if i enable the switch to match display mode, when i leave fullscreen at 24hz it just shows a static image on video player.

We fixed the issue where if you RDP into a PC running this build with certain GPU configurations, when you go to sign in to the PC locally it will appear stuck at a black screen with only the cursor available We fixed an issue where toggling some DX9/DX10/DX11 games between windowed and fullscreen (for example using Alt + Tab) could result in the game window become black on certain PCs. |

and don't worry i watched them just taking the image without AR correction and 2x NN and x2 NGU sharp should be better than this i guess. even with NGU sharp i can see the gaps between the pixels. Quote:
so i'm just choicing an lesser evil that's not a general increase in image quality in my book. do the good out weight the bads i'm pretty sure it is still just a trade in my book. and just to be sure you used add grain for NGU didn't you? the image looks a lot more details and that's something a scaler can't do. there is a reason i ask you if you could add add grain for other scaler. not the creators intend but what ever doesn't look unnatural on an old DVD. EDIT: if add grain was really used plz don't redo the screens that looks time consuming. Last edited by huhn; 30th October 2017 at 13:09. |

My two cents about nearest neighbor. If it's still in madVR and accessile through a programmable key, why not getting it back in order to use it for profiles? Maybe with a (useful for pixelart and old videogames) note beside it?
It's still there for image downscaling (where I don't see how and when it could make sense). I couldn't care less, personally, about it. But if I watched, for whatever reason, lots of stuff like that, not having it available for profiles would irritate me. |

the image upscale page is pretty much full and AFAIK this stuff is time consuming.
before something like this is added i would prefer a scaler like RAVU or something like that. pretty sure there are more user that find this scaler useful than NN. |

Also, which GPU and driver version is this? If Nvidia, DON'T use 387.xx or 388.xx, use 385.xx, please. Only in X direction. Y res stays the same. So it's much less than 42%. If you say an image was upscaled by 42%, usually people mean both X and Y. Quote:
Why would 2x NN have been better, though? This whole discussion is about whether upscaling helps or harms image quality. So if I want to create digicam shots to prove my point, I *have* to create shots that show unscaled vs upscaled. If I had upscaled both (with NN vs NGU) I would have only compared NN vs NGU, I would not have compared unscaled to upscaled! If you want to compare NN vs NGU, we can do that very easily and directly in madVR without using a digicam. Yes. Which is a good thing because it proves that my digicam isn't half bad. The photos faithfully show what my LCD monitor does, when displaying your DVD image unscaled vs upscaled. The photos show that displaying the content unscaled suffers more from the (sub)pixel grid of my LCD monitor than when using upscaling. The same effect exists when comparing 1080p content on a 1080p vs 4K display. It's an important argument that displaying 1080p content untouched on a 1080p display doesn't faithfully represent the 1080p content, because many displays don't have perfectly rectangular pixels with 100% fillrate, and even more importantly, many displays have RGB subpixels that are positioned next to each other, so they don't cover the same area. This subpixel positioning can introduce additional aliasing/combing artifacts that aren't even in the source image, as seen in my digicam shots! So when showing a 1080p frame on a 1080p display, actually image quality gets lost due to the gaps between the pixels and the placement of the RGB subpixels. These problems of imperfect display technology are nicely reduced by upscaling the 1080p image to a higher resolution. And my digicam photos show that quite nicely. Quote:

we could argue about that forever because it never really fair to compare to different image sizes. maybe with 2 CRT next to each other but i'm pretty sure we will still find issues in that setup. Quote:

supersampling isn't indicating it is doing it in one way only so we can't really call that image unscaled anymore. and add grain clearly benefits from a higher resolution. with is a clear plus for your argument. Quote:
