Unless you want to use a specific GPU for decoding, it makes no difference for DXVA2-CopyBack.

Ticking filter madVR in MPC-HC or PotPlayer won't "stick". The option is there on the dropdown menu but it only opens madVR config window. Still can't see any activity? Only get this: Active Decoder: <inactive> Active Hardware Accelerator to use: <none> Well, maybe no need to dig deeper on this, I'm pleased with what my eyes sees so far. |

@sneaker_ger
Thanks, my bad, sorry, didn't tick the right filters, now it's showing correctly in LAV. Looks different though in PotPlayet, I'll fix that. Got LAV showing in PotPlayer. All is good! Last edited by varekai; 14th January 2018 at 17:09. Reason: info |

With cuvid you can get back the deinterlaced frames for further processing (ffdshow, avisynth etc.), but for madVR this is not needed. |

1) The MPC-HC main thread wants to close playback. It asks the graph thread to do the dirty work and waits for that to complete. 2) The MPC-HC graph thread obeys and tries to close playback, starting with trying to close the subtitle renderer. 3) Trying to close the subtitle renderer freezes for some reason. It seems that the subtitle renderer is waiting for the subtitle queue to receive new subtitles, and somehow the queue seems stuck. So you might be able to reduce/fix some of the freezes by using a different subtitle renderer, or maybe by changing the subtitle settings, like queue depth or something. Quote:

But for lossless HDMI transport, 8bit is just fine for HDR/ST2084, as long as you use proper dithering. You won't get *ANY* banding, whatsoever! However, you do get a higher noise floor. So if you can do 10bit, by all means do it. I don't think anybody is recommending to avoid 10bit. The original question we were discussing was whether it's better to use 8bit RGB or chroma subsampled 10bit, and there my vote goes to 8bit RGB. So basically I'd rate: 10bit RGB > 8bit RGB > 10bit 4:2:2 > 10bit 4:2:0 That applies to both HDR and SDR. Quote:

Not yet, but "soon". But then, I've been saying that for a long time now. I hope it will be really soon now. I already have it working, just need to make it available the right way. |

Very important: Do these white dots show up in screenshots? Try disabling FSE mode, do the white dots still show up? If so, press the PrintScreen key and check if the screenshot in the clipboard contains the white does. It doesn't matter that the screenshot will have washed out colors. Only the white dots matter. Usually, random white dots are caused by one of these things: 1) Either faulty GPU RAM (overclocked?). 2) Or faulty GPU chip (overclocked?). 3) Or faulty GPU drivers. 4) Or faulty decoding (hardware?). 5) Or faulty HDMI cable or HDMI output/input ports/chips. It's unlikely to be madVR's fault, unless many many users have exactly the same issue. If only a small part of the users have this problem, it's most likely one of the 5 reasons above. Quote:

However, if you consider that most 1080p Blu-Rays these days are downscaled by the studio from a 4K master, we can consider upscaling as trying to undo the studio downscale to restore the original 4K master. A studio downscale actively destroys information, though. So it's impossible to restore the original 4K master perfectly. However, NGU is able to restore sharp edges very well. But the main thing that gets lost is texture detail, and there's no mathematical way to restore it because the information is simply missing from the downscaled image. In theory it should be possible to build a large database of typical real world textures and try to restore lost texture detail by intelligently interpreting the downscaled image and injecting stored texture detail from the database into the image. (Actually, that's what some neural network algorithms already do.) But this approach has many very big problems, which make it currently impossible to use for video upscaling. Quote:

Basically, for both upscaling and image interpolation, to get best results, you need to use non-linear algorithms, and then signal theory no longer applies. Quote:

It would make sense to do that. But you can also try to find out for yourself why the splitter doesn't seem to report HDR to madVR. Which splitter are you using? |

Nope, that just means that the HDR Metadata says that the movie was mastered with a DCI-P3 display, it doesn't mean madVR is doing any conversion. Quote:

1) I've reported to my Nvidia driver dev contact that Nvidia GPUs generally have a bad pixel clock / refresh rate for any x/1.001 modes. I hope that he can get this fixed. That way even without any custom modes we should get much better refresh rates, which should also help for 3D. But I don't know if this will get fixed, or how quickly. 2) You could try writing down the optimized timing mode data and create an EDID override based on that, using CRU. I've no idea if that will also affect 3D, though. Maybe an EDID override can also have an extra entry for 3D? I don't really know, to be honest. Quote:

For downscaling try SSIM1D 100, or Bicubic 150. For upscaling try NGU Anti-Alias (for very low res aliased sources) or NGU Sharp (for higher quality sources). The different in image quality will be larger if your source has sharp lines/features. With blurry sources you'll barely see a difference. |

I think I asked this before, but I can't remember if I actually did, or I just thought about it, so please forgive me, if I am repeating a previous query.
Is it possible to implement support for other 3D input formats than just MVC? I mean, when I convert my 3D blurays, I usually use a SBS or OU format, and it would be nice, if I was able to make madVR go into "3D-mode" for these, so I get all the same features with that as with "real" MVC-movies, instead of just playing them as 2D and then manually switching my projector to 3D. Optimally, with will read the stereoscopic metadata from LAVFilters, and automatically detect the input format based on this and put madVR into 3D mode, when needed, and besides that, make a keyboard shortcut to manually tell madVR the input format of the video. |

Would the algorithm of madshi can be a a plugin or a DLL library or something for other Picture viewer or Manga viewer to use?
Seems most of photo viewer is still using poor resize algorithm like bicubic or lanczos. But NGU or even JINCS is much better than those resizer. I'd like to enjoy these amazing technologies to view my photo and manga or picture in the future. Is it possible? |
