Agreed, I use NNEDI3 32 for Chroma but ONLY because I got power to spare on my 980 ti. I tried comparing NNEDI3 16 vs 32 vs Jinc AR and I can't see a difference when it comes to Chroma upscaling on actual content (SD or HD). Maybe with a special test file I could see it.
I'm using NNEDI3 256 (+Jinc AR for the final touch) for "image upscaling" (720p>1440p usually) and I can just change the Chroma upscaling back to Jinc AR for 30fps+ content (for 24, 25fps I don't even need to bother). Last edited by kalston; 19th February 2016 at 13:41. |

Hey Madshi,
I might have discovered a very minor bug in my setup: For some reason NNEDI Luma quadrupling doesn't work on my 640x480 source (to 1080p) if I set it to 2.4x (or higher). It does work if I set it to always. Doubling works as intended. I'm using MPC-HC, an r9 290 with catalyst 15.7.1 on win7 pro x64. Thanks in advance! |

640x480 * 2.25 -> 1440x1080. The factor is below 2.4.

Hi guys, i am having a problem that i think is related with madvr.
Sometimes when i am playing a tv show and i skip to the next episode, it just shows a black screen, and even returning from fullscreen i can't play the episode. i have to close mpc and open the episode again. this do not happen when i am not in fullscreen. Maybe is related to the change in refresh rate, i use the option to change refresh rate in madvr. madvr version 0.89.19. When i am not in fullscreen i can skip all episodes in a season without any problem, but in fullscreen it sometimes give me this blackscreen. Using windows 10. |

Why is there NNEDI3 for Chroma Upscaling and Image Doubling/Quadrupling, but not Image Upscaling?
I am also a bit perplexed about the whole Bicubic thing. Are you saying that all the Image Downscaling options (and perhaps others?) are just renamed version of Bicubic? Catmull-Rom = Bicubic50, SSIM = Bicubic125, Jinc/NNEDI3/others = some other Bicubic??? Last edited by XMonarchY; 19th February 2016 at 18:45. |

NNEDI3 can only scale 2x, chroma is always 2x and image doubling/quadrupling part I leave to you. NNEDI3 can double in both directions X or Y, Super-Xbr for example can only double X and Y. Also, I remembered reading this same question you asked in 'madVR options explained' thread, took me seconds to find it, http://forum.doom9.org/showthread.ph...05#post1710105 Last edited by ibius; 19th February 2016 at 19:23. |

Not "all" are Bicubic, but Catmull Rom and Mitchell Netravali are (and Bicubic and SoftCubic of course). But they are all different variations of the cubic interpolation. That C-R happens to be exactly the same as Bicubic50 is just the way it is.

But if I use MPC-BE with LAV filters the problem goes away. Just tested and it's the same problem also with the latest madVR version. |

You must know what NNEDI3 is -- image doubling, not image upscaling. And of course not all of the downscaling options are Bicubic; they are no different than the image upscaling algorithms. Many probably use very similar approaches to image scaling, with similar math -- but they are not the same.

madshi,
MPC-HC menu > View > Statistics shows the wrong framerate when using madVR. With all other renderers it displays the playback framerate of the video (video framerate * playbackspeed). In case of madVR it shows the screen refresh rate. According to U78 the info is gathered using "get_AvgFrameRate()" method provided by the "IQualProp" interface of the filter graph.

So I wouldn't necessarily call it wrong. If you use a mode that only presents every frame once, ie. D3D9 or Overlay, it shows what you might expect.

I use D3D9. Disabling "present several frames in advance" indeed gives the framerate value I expected.

I've found some setting which I think substantially improves low-res/bitrate sources, but looks good for good sources too:
Image enhancements: Enhance detail 1.0 (pre-resize) Image doubling: NEDI Image upscaling: Lanczos3 AR sigmoidal Upscaling refinement: SuperRes 3 |
