OSD: http://imgur.com/319PabC I can't even understand if PC Mode is always enabled, or if it's only enabled (or actually disabled) when switching back from WMC. Is here someone with a Samsung TV that can explain me how to see when this PC Mode is enabled? |

Thanks for the responses, found something I was doing wrong, selected LCD and not Plasma for screen type. Also thanks for the link, however I'm using Calman for generating the 3Dlut, which is why we have seen the changes to the APIs lately. Using calman I can generate a 3Dlut directly and using thousands of data points, very cool actually.
I'm going to give it another try right now and see where I get. Thanks, ERIC |

this picture can help
http://madshi.net/madVR/ChromaRes.png watch it unscaled @ 100 % zoom. without PC mode you shouldn't be able to see the 4:4:4. i guess something is blocking madVR from switching to 50 hz. try it without any other program in the background. |

I'm trying to play a 1080i29.97 H.264 video with force film mode and output at 23hz. madVR says cadence is 4:4:4:2 but it's just continuously repeating frames and stuttering. Sometimes if I skip back in the file it will start playing smoothly even though it says frames are repeating. I can IVTC it with tfm().tdecimate() to 23.976 and encode it with x264 and it plays perfect. Any suggestions? Is this a limitation of madVR not being able to play 4:4:4:2 correctly?

did you maybe mean 4:2:2:2 or 2:2:2:4? if yes this is already reported http://bugs.madshi.net/view.php?id=201 Last edited by huhn; 19th January 2015 at 12:37. Reason: wow my math skills today... so bad |

I am trying to set a 3dlut file to correct my display. I added my measurement values in the settings and pressed apply. Madvr asks if I want to downlaod and install yCMS now? I press yes download starts and madvr reports
Downloading yCMS failed. How can I get yCMS installed? (windows 7 32bit) |

you could try argyllCMS when your meter is supported: http://www.avsforum.com/forum/139-di...argyllcms.html
not an answer to your question sorry. |

with Display at 59.9Hz I see only 444, with MPC closed I glimpse 422 but definetely see 444, at 50Hz (using the WMC/madVR bug) is like MPC closed, at 50Hz (directly) like MPC closed, at 23.9Hz like MPC closed. Doesn't this mean with all the above Hz my TV is in PC Mode? And if it's so, why the image become more saturated switching back from WMC which take me from 59.9Hz to 50Hz? Replying to huhn: without any program in background wtv files are still at 59.9Hz. |

Hi.
I want to test different upscaling methods and hardware combinations with 720p content up to 1080p and I'm in the need for some sharpness pattern in native 720p... I just can't find any, it's really odd. My goal is to compare the upscaling results from MadVR with those from my TV. With some high bitrate files I prefer to set the desktop to 720p to lighten CPU workload, but I don't know how much quality I'm losing to this, with movies is very difficult to notice. With a sharpness patterns it would be easier. Does anybody know where can I grab such a test video file? |

(Maybe I'm wrong, but I understand the process as follows)
Because I'm not using the GPU to upscale 720p to 1080p, but the renderer (madVR custom pixels shaders) and if I'm not wrong, that relays on the CPU, hence the sloppy playback and frame dropping that I get when upscaling to 1080p via custom pixels shaders, specially in high bitrate files. So, in other words: 720p to 1080p performed by GPU: Smooth. 720p to 1080p performed by CPS (ie Lanczos 3 taps): Sloppy. 720p with no upscaling (720p desktop fed to TV that TV upscales to 1080 panel): Smooth. Yes, I can get smooth playback with some options, but I would like to test the sharpness with each one of them. |

Pixel Shaders run on the GPU.
And while reducing your resolution will result in less work for the renderer, it'll also cripple your performance, as the screen has to do the upscaling, in questionable quality at best.. You are better off using cheaper upscalers in madVR than letting your TV do it.

madshi: A small feature request. I know why you have done things this way, but please give an option to disable 'on top' for the madVR settings dialog. With it sitting on top of all other windows (and it has no minimise button either), it makes it more difficult to help other people with problems with madVR (for example, you open the options dialog to find the name of an option, and then want to type that name into an email - you can't until you then drag that window out of the way somewhere, and you have to do this each time you open it as it always opens in the middle of the screen).
Thanks! |
