Personally I found SmoothMotion when set to 'always' to significantly soften the image. I still use it on it's basic setting 'only if' but my TVs motion interpolation does a far better job of keeping details whilst providing much of the same benefit as the 'always' setting. SVP is also something you could look at if your TV doesn't offer this functionality. Soft pans are just ew. |

SVP actually interpolates the data between frames and may introduce artifacts. It produces the so-called soap opera effect like what most TV's built-in cinemotion filter does. Tried it before, hated it. |

So if I set Image Doubling to double Luma resolution "always - if upscaling is needed" what is the resolution threshold or perhaps "scaling factor" at which "upscaling is needed" for presenting content at 1080p?

I mean to say, when does MadVR determine scaling is needed? It won't double a 1080p clip, if I'm already at 1920x1080 because scaling is not needed, but it will double a 720p clip.
What about clips larger than 720p, but smaller than 1080p? Some get doubled, and some do not. How does MadVR determine this if set to "always - if scaling is needed"? What is the magic number? |

madVR determines scaling is needed if scaling is needed. There is no magic number, if the video get resized up at all it is supposed to use NNEDI3 (1079 and below with a 1080p display). With samples where this doesn't happen is the horizontal resolution equal to or over 1920?
If you think NNEDI3 is not used sometimes when it should be please post a sample that demonstrates the problem. |

How do you manually activate deinterlacing without changing the file name on a progressive clip? I tried a 720p60 clip I know is 24FPS based with the "disable automatic source type detection" box checked and "force film mode" checked but nothing seemed to be happening.

Mainly so that the LCD can be made cheaply I think - if you use the tiled arrangement, you don't need a new, beefy controller for 4K, just two less complex ones. I don't know much about that area of hardware, but it is possible that at the beginning, there even weren't controllers that would handle a single 4K matrix (or maybe the latency would be too high?). And many LCDs were going to require two connections anyway (HDMI or DVI)...

i just did a test, i set it back to 60hz all is fine, i set madvr to change it to 1080p59 it has the same problem. In previous madvr versions this used to work, not really sure when that was broken, but the reason for trying to use 1080p59 is to remove judder without the blur caused by smooth motion.

I don't see why you would want to use IVTC on true 59/60 fps content like sports, that doesn't even make any sense. It's supposed to be played back at that frame rate because it was filmed that way. Last edited by StinDaWg; 25th April 2014 at 06:25. |

Here's a clip that glitches while seeking and from the start: http://www.mediafire.com/download/5f...int%3Dfilm.mpg it's reproducable most of the time, just jump around. If SM is off it doesn't happen at 60hz. At 48 and 50hz the glitches happen at 72 and 75 the glitches don't happen.
On the fly ivtc is kind of hard I guess. If you don't want to add a setting how about scanning a part of the video, in the middle, before determining what to do with ivtc, refresh rate, sm? I'd surely give up a few seconds of life to get these corrected.

This anime clip (One Piece #444) is 1440x1080i59, obviously 2:2 cadence. When I press Ctrl+Shift+Alt+T twice (or add the tag "deint=ivtc"), the desktop refresh rate changes to 23Hz, resulting in lots of dropped frames. (The list of display modes is "1080p60, 1080p59, 1080p50, 1080p30, 1080p29, 1080p25, 1080p24, 1080p23", all of them are supported in my display.) So I have to add both tags "deint=ivtc" and "refreshRate=29".
Of course leaving ivtc to the graphics driver is the easiest @59Hz (2:2 means no judder). But it seems that NNEDI3 breaks it (I turn it on for 1.2x or higher). Last edited by renethx; 25th April 2014 at 07:53. |

True 60 fps content is 1:1, or more precisely, those things don't apply.
A Telecined PAL video would be 2:2, 50p which should be decimated to 25p.

it simply treate it as Interlaced and check it so a 720p60 is treated as 720i60 120 fields and if this is 2:2 it is not touched and output as 720p60. 720p50 is treated as 720i50 100 fields and if 4:4 is detected it is supposed to decimate it to 25 fps but this is currently not working only 6:4 in 720p60 is decimated to 720p24 at the moment. |

http://forum.doom9.org/showpost.php?p=1678622&postcount=26139 MadVr uses the IVTC cadence detection to see if a 720p60 stream is 24 not 60, the real difference is that all odd field should match the top field in the same frame. so there shouldn't be an uneven number in the cadence. force film mode = MadVR IVTC btw. i was talking to nevcairiel this is what i said to you Quote:
