I have the big brother but (no matter what I did) I didn't managed to get 4:4:4 with any combination that I've tried. I have to say I use hdmi-hdmi from my laptop. And this review also says that they couldn't make it work: http://www.hdtvtest.co.uk/news/lg-32...0101120901.htm Quote:
The 23hz vs 60hz is a different matter, just try it out how it looks. Btw: do you know any display device (tv or projector) that can do 4:4:4 via hdmi-hdmi AND 23hz or 24hz???

Help please.
* Reducing GPU buffers reduces the GPU memory footprint which with just 2GB on 4K material is good for my setup especially given the need to run copyback DXVA 2 with madVR. Is there any practical problem with running just 4? * Since I run 64bit builds of LAV, MPC-BE and madVR, and I have ample system ram at 16GB, I see no reason to change cpu decoding buffers from default. Does more of less than default decoding buffers have any practical impact? * Whats with present frames in advance? Why do this? If it is a good thing, how many should be done? Whats the relevant factors with deciding on this setting? Thanks Last edited by Nullack; 23rd December 2015 at 12:06. |

Errr ... What do you mean? He was talking about the Samsumg tv latter on not the LG.

Not sure what part of the chain is the problem here, but the exact same video is being detected as having BT.601 primaries on one opening and BT.709 on the next. I've noticed this bug on other videos too. Whats worse, is that it actually changes the color of the video (mainly in the greens). Is this a video encode bug or an actual bug in madVR/LAV's detection code (also using) xySubFilter and MPC-HC). So far its only on videos were instead of the matrix being 'best guess' its 'upstream' for the matrix and 'bitstream' for the primaries (on videos were in the mediainfo just the matrix has been set as BT.709, leaving the primaries guess to the chain).
http://i.j2.io/9EM0.png http://i.j2.io/8T2O.png (size difference is due to poor screenshot lossless PNG crop, not due to different frame. Color difference is there on madVR itself). Last edited by ShadyCrab; 23rd December 2015 at 12:09. |

It's true that the font size is now allowed to get smaller if your playback window is very small. The purpose of that is to fit more of the stats into the window. If I didn't do that, the font size would be bigger which is easier to read, but a lot of the OSD content would then be cut off. Quote:

It would be good if you could make up your mind if you want support for your specific playback problems in this thread, or in your own thread, because if you ask in both threads, questions and answers might overlap, causing me more support work. Thanks. |

Yep - sample, please! I need to be able to reproduce this on my PC. |

SUBTITLES - HELP
Today I wanted to look into the problem of moving subtitles into black bars not always working as expected. It has been reported to me that e.g. moving SRT subtitles into the black bars stops working if the SRT contains <i>italic</i> subtitles. So I've tried to reproduce that just now, but can't! Does anybody have any sample with which I can reproduce that moving subtitles into the black bars works at first, but then stops working at some point? |

TVs? Almost none, AFAIK (and see IRL). Only monitors - and i use this on monitors (first Samsung 959NF, then Dell 2707WFP) at my primary PC (to view short videos), not theater PC.
Russian(Cyrillic). But - ANSI CP is 1251 (and OEM 866) on my PC - and if you internally use AnsiStrings - it shall not be a problem, i assume. Last edited by SweetLow; 23rd December 2015 at 17:15. |

No problem. I'm glad we have it in madVR though.
Different issue: I'm instantly getting lots of dropped frames when I enable black bar detection for a HEVC 10 bit 4k 50fps video. Neither GPU nor CPU load is at max, so probably performance can be improved? The video plays fine without it (except of some weird high bitrate locations). CPU is a 4770k@4.1Ghz and GPU 780 Ti@1.2Ghz. |

some extra informations. software decoding with IVTC sees 3:2. quiicksync decoding with IVTC sees 2:2 (no repeat flags) and there is no combed file in the whole source. and ffmpegsource uses 23p for it. Last edited by huhn; 23rd December 2015 at 18:13. |

That's just what the decoder reports, but not what madVR actually draws. Try frame stepping again, you should be seeing 24fps not 30fps. |

OSD upscaling works great, however the text is hard to read when height is less then ~630px or within the smallest OSD size range.
Should peak luminance be set to 265nit for a 300nit (measured) display? Last edited by dansrfe; 23rd December 2015 at 18:39. |

Is there some non-linear stretch option with MadVR I'm not finding in the various options ... i.e. like ffdShow warped resize or Cyberlink PanoVision(tm)(r)(c)(wtf)?
If not, would it be possible to implement this - the various tv sets all seem to have a 4:3->16:9 non-linear stretch feature as it's so convenient for watching older content on a newer wide-screen display. The catch with ffdShow is that it's software-only and is stuttering esp. when enabling other post filters.
