If the video appears smoother in 60Hz+SM then an actual 24Hz mode, then I would draw the conclusion that your TVs 24Hz mode isn't quite perfect (which unfortunately a bunch of TVs get wrong).
As others have said, SM isn't a replacement for the interpolation TVs perform, or SVP, its just a way to avoid motion judder from mis-matched refresh rates.

Im sure everyone here says that SM will never work on any of its settings if the framerate is set to 23/24Hz and everything in between. Its easy to see, by checking in the onscreen log, it will state Smooth Motion is off, even though you have "only if there is judder ticked". |

None of those options change the behavior of smooth motion, only when it turns on or off. On a 24Hz display and smooth motion set to "only if there would be judder without it..." the output is the same as disabling smooth motion entirely.

When watching 4K HDR movie, does it suppose to be 8 bit or 10 bit ?
http://imgur.com/GWabH4f I'm using Nvidia 382.53 drivers with HDR in windows disabled. When I enable it, it's become 10 bit Everytime I enable HDR and run the movie my screen turn black, the sound keep playing but I can't see anything, changing the nvidia settings from the Default color settings to nvidia Color settings and using HDR in windows YCbCr 422 12 bit limited works fine. but if it's on default it causes black screen . is it a issue with the 382.53 ?

Is this a bug in 8.1? Can anyone suggest a workaround - it's hard to read anything if I drop the scaling down. |

damn i love madVR
i have two specific questions, my tv support 4:2:2 chroma subsampling, due to the fact that half of the pixel averages the color value, do i still benefit from higher chroma upscaling algorithms for the original video size and/or doubling the video size? dithering.. if there are dither patterns the "reduce banding artefact" does its magic, if i see noise it doesn't get better of worse with any dither option, i don't see any difference while switching options or disabling dithering, is there something i can do about it? (no noise reduction is set in my drivers or TV) |

Use control-J to toggle madVR's OSD to see what it is doing and trust your eyes when judging quality. Quote:
"reduce banding artifacts" happens before dithering, everything in madVR happens before it dithers. Any changes noticed due to it are not changing the dithering as done by madVR. Dithering is pretty subtle, you hopefully wouldn't notice it with a display at 8 bit or higher. However, if your display or GPU is doing a conversion (such as to converting to 4:2:2 internally) it will mask any changes in madVR's dithering. Stick to ordered dithering if you don't notice a difference, it is fast and good quality. There is no reason to use error diffusion if you cannot see an improvement but disabling dithering is always a bad idea. You can also temporarily set your display to 4-bit or even lower, to see what changes in the dither pattern but make sure the "trade quality for performance" option "don’t use linear light for dithering" is unchecked. This is mostly for curiosity as optimal at 4-bit might not be optimal at 8-bit.

Only D3D9, no D3D11
I have been looking through the forum, but haven't found any solution yet: when using madVR, I always only get D3D9, not D3D11.
Zoom Player 13 with madVR 0.91.11 LAV 0.70.2 Windows 7 64bit Nvidia GTX980 with driver 384.76 Windowed, I get: D3D9 old path With FSE, I get: D3D9 new path I think I have chosen all relevant configurations for D3D11, but I am not 100% sure. Anything I should test/check/change? |

I had already enabled this setting. Somehow it doesn't work. Is there a debug log or any other way to check why D3D11 doesn't kick in? |

Do any of madVR's settings work?
