But I still prefer how the "four way" look compared to "circular". Jinc is too smooth. Last edited by James Freeman; 2nd November 2013 at 11:25. |

I'm not a fan of noise/grain reduction at all. So that will probably be the very last algorithm I'll ever look into (if ever at all). If you think that debanding kills detail then what does noise reduction do? It's a hundred times more destructive to detail than (proper) debanding is, IMHO. Quote:

Yes, unless you activate the old FSE rendering path ("present several frames in advance" unchecked), then I have to use IDirect3DDevice9, because the old path doesn't work with IDirect3DDevice9Ex. I can understand if you like the small sharpness advantage Lanczos has over Jinc. But there's really no such thing as "too smooth". Nature is smooth. You won't find aliasing in nature. Aliasing is an artifact of digital video / image processing, and there's no good side to it. Last edited by madshi; 2nd November 2013 at 11:30. |

I've found a few denoising PS scripts but all they really do is blur the picture, no more noise heh. I would entirely be willing to compromise small details for MPEG deblocking or VHS noise suppression. Sammy and especially Hitachi TV's do it really well IMHO but of course it's all 4:2:2. I'm colorblind so judging on deposterizing is not an easy task for me and I'll give you that I've only looked at the worst case scenario screenshots posted in this thread, I'm sure the optimal settings you'll all agree upon will be well worth playing around with Quote:
There are indeed cases when you can find valuable data in the BTB/WTW but this can also end up being bogus padding and ffdshow works in 8bit anyway. Quote:
I think MPC can open JPG's so I could force the sRGB gamut in mVR et voilą. I'll try to get it to open PNG, GIF, RAR and ZIP. All I would need is a way to go between "1:1 scale" and "shrink to fit", which is not currently possible I think.. Last edited by leeperry; 2nd November 2013 at 12:20. |

Another Chroma Upsampling test video to test which upsampler does a better job.
There are 2 versions inside. 1. 4:4:4, no chroma samplig at all (perfect RGB). 2. 4:2:0, a typical video chroma subsampling (BR/DVD). For the 1080p Version: Set MPC like so to keep 1:1 pixel ratio: View -> Video Frame -> Normal Size. For the DVD, set to Default "Touch Window From Inside" and stretch the window to fullscreen. Play the 4:2:0 video and pause it anywhere. Now play with the "Chroma Upscaling" options. Tell me what difference you see with Jinc, Lanczos, Bilinear, and Nearest Neighbor.

please for advice, what is the best options for Exclusive Mode Settings - ( how many video frames shall be presented in advance 1-16 ? ) when is disabled Smooth Motion !
or when i use 24hz for my TV no matters what is Smooth Motion on or off is not functional when is play movie ? Last edited by LilScrappy; 2nd November 2013 at 19:12. |

I was able to come up with a solution with very little to no security risk with a batch file: Code:
DisplaySwitch.exe /internal ::or /external for TV runasspc /cryptfile:"dwm.stop.spc" /quiet runasspc /cryptfile:"dwm.start.spc" /quiet

Although not the place, but I am happy to announce that the latest MPC-HC Nighty (LAV Filters 58.2.105) supports HEVC/H.265 & VP9 and works perfectly with MadVR.
A new era has began. EDIT: LAV 0.59 is out few minutes ago. Last edited by James Freeman; 3rd November 2013 at 17:22. |

I'm using FluxSmooth for the moment and with a good combination of spatial (value = 2) and temporal (value = 4) denoising, it doesn't destroy details and can be very useful with DVD, bad videos and even some mkv. It's like all postprocessing filters, it needs to be well configured. FluxSmooth has also the advantage to try to preserve the grain and just reduce the noise. I'd really like that one day you make a good denoising filter. I don't like AviSynth it's very buggy sometimes. Quote:
I was wondering, why does your video in 4:4:4 crash all the times with Ffdshow? It doesn't support 4:4:4? I use it only for some postprocessing filters. Last edited by Werewolfy; 3rd November 2013 at 14:50. |

2. Don't change default settings unless you have problems like dropped or delayed frames. |

Anything above Bicubic+AR (or even Bilinear) for chroma upscaling is an overkill. Although I still use Lanczos3+AR. EDIT: I added a more comprehensive Resolution Upscaling test in this post: http://forum.doom9.org/showpost.php?...ostcount=20688 As you can see the difference is small to indistinguishable, except when the pixels are aligned in a perfect diagonal (pixel by pixel), only then I see Jinc is doing something positive. In all other diagonals Jinc just blurring them. Quote:
I used the most basic settings in x264 for converting: "x264.exe -o output.mkv input.mp4" Last edited by James Freeman; 3rd November 2013 at 15:40. |

bilinear http://i46.img-up.net/bilineare1fb.png jinc 3 ar http://v87.img-up.net/jinc3ara146.png just have a look at the red 29 in the top right is better to read with jinc 3 ar and the red border in the middle bottom is way better too |

No problem with that sample here.
Radeon HD5850, Cat 13.11 Beta 8, Win7 x64 Laczos 3 Chroma Upscaling(AR), Catmull-Rom Downscaling(AR, LL) to 1920x1080 rectangle, dithering on Last edited by sneaker_ger; 3rd November 2013 at 18:27. |

It does look better compared to Bilinear. But I still can't see difference between Bicubic and Jinc in Chroma Upscaling. IMO, Jinc for Image Upscaling is way too soft and hogs too much resources, Bicubic will do just fine and nothing beyond is visible OR needed. For Chroma, again nothing beyond Bicubic is needed.

This only happens when image upscaling/downscaling are set to use any of the options under processing done by custom pixel shader code (unaffected by chroma upscaling setting). Once I set these to use an options under either processing done by GPU texture units or processing done by GPU video logic windowed mode works fine. My laptop uses an nVIDIA GeForce GT 635M with the latest 331.65 driver. Not sure if this is a driver issue or not.

From what I've heard a lot of people have reported problems with shaders and recent drivers on Nvidia cards (not madVR specific), so that might be related. Haven't seen any problems with madVR on my GeForce GTX 580 though.

Try lowering GPU queue, going from 8 to 4 with 1GB vram worked for me.
