Ah, ok, that makes sense. Maybe it should be reported to x264 as a bug. If x264 isn't able to subsample chroma correctly then it should error out with RGB input. Producing incorrect results is a bad idea, IMHO.

that's what i don't get he inputs rgb but it encodes YCbCr 4:2:0. and what conversion is used for rgb -> yua bt601, bt709 or nothing?? like nevcairiel said avisynth and add the right tags to it. |

It always does that, unless you actually tell it to encode in 4:4:4 or RGB directly. I assume thats done to produce the most compatible files.

I haven't seen 4:2:2 telecined source either. It would be nice if madvr could work around conversion to 4:2:2 though.
While I don't interpolate myself, I do occasionally decimate with avisynth because madvr's ivtc doesn't handle some situations such as this simple one which is telecined material that was deinterlaced so every fifth frame is a duplicate. It would be nice if this would work without disabling display changer and smoothmotion. I would think MadVR would be able to handle this. I suppose I could ask in the ffdshow thread, resizing avisynth works fine with player and madvr, is this being passed from ffdshow or is it calculated by player/madvr? On bigger screens a lot of grain can be unbearable. NCIS: LA has a lot of grain, I'll try to remember to cut a sample of it when it airs again in a few weeks. I haven't messed with any avisynth filters for it but will do, after seeing madvr's deband vs avsiynth methods, it would be interesting to see what madshi could do when/if he finds time for something like this though. One thing about madvr's deband is it doesn't add grain, at least not much, while avisynth deband filters do, but in most cases the no added grain is desirable imo. I really don't get dynamic contrast, it's become very common feature on lcd's but it looks horrible imo, lcd's need to work on getting deeper blacks, not brighter. I don't think still pictures do nnedi3 much justice, while there are definitely some pros and a few cons of the still picture castle comparison to bicubic. At 24fps those cons pretty much disappear IME.

I have dug dipper into the chroma analysis, and....
Yes, the actual chroma on a blu-ray is shifted 1 pixel to the right. And when selecting a Chroma Upscaler in MadVR this moves the chroma 1 pixel to the left where it should be. (yes I feel stupid right now) I also included a nice video of my reference blu ray to show you guys how bad (low-res) a blu-ray chroma really is, And how of a good job MadVR Chroma Upsampling really does. Please download this clip and bask you eyes in amazement of: The Ugliness of Blu Ray Chroma Well.. you learn something new every day.. only I do it loudly. |

On LCD, the other dynamic contrast called "dynamic contrast" is a problem, and at least on my TV, he can't be disabled. I suspect it of causing flickering. |

I don't like the idea of these enhancements (IFC, DCE etc). My panel has many options like this and I have them all turned off.
I must admit the idea of an upscaler that takes a few frames of information into account when up scaling sounds interesting. I also would also be interested in experimentation of forcing a panel that supports 3D at 120hz to display a normal 2D picture at that rate. Its just not possible to put a 3D panel into a 120hz refresh rate via windows unless its a dedicated PC monitor. I think most only go to 120hz when they have 3d material sent down the HDMI. So what Im suggesting there is to send a standard 2D 24fps frame to the panel as 3D (make the frame the same for both the left and right eye). I think that would be intresting because plasmas at least do not have options to watch 2D at 120hz unless you activate IFC but that sucks. I guess it may allow for picture improvement (esp in motion scenes) but then again it might be worse. |

It is badly encoded and a bit much to expect madvr to find and remove dupes by default but using deint=ivtc I'd expect to handle it, the pattern doesn't get any simpler. Instead madvr does an unnecessary deinterlace and chooses the wrong frames to remove.

Anyway I figured the best option as of now is to turn off all 3d related options in nvidia when I'm not playing games. Last edited by magus; 31st December 2013 at 02:07. |

This thing can run in realtime apparently, too bad vReveal might very well have gone belly up as their domain name is a 404 now. This woulda killed in mVR |

ivtc is not simply removing duplicates if it does this terrible thinks will hppen anime is from time to time 5 fps or even lower that'S not how ivtc works. ivtc removes duplicates from filedmatching but how to field match a progressive source? use it on interlaced videos and nothing else. |

I agree. Hopefully madshi won't waste time on stuff like that.

It depends of how would be the result with new algorithms from madshi... It is turned off on your TV because you are not happy with the results... Me, I would be happy of each new option that could improve the picture quality of my movies

We have those turned off because we want our picture to match how the director of the movie wanted them to be. Once you start changing settings adding dynamic contrast etc you begin to ruin the experience of getting lost in the film experience. This is because the atmosphere the director is trying to create with lighting is lost.
