It still amazes me how the switches for full range (0-255) and limited range (16-235) sometimes do nothing. It's happened to me with 3 different TVs and 2 different PCs (one with Intel IGP, one with nVidia GPU).

@madshi
does madvr support numpad?? i create shortcut "Ctrl+Alt+1", but if i press 1 in numpad(on my laptop) it doesn't work. i should press 1 located at the top of keyboard for that shortcut.

In particular, madVR uses RGB (only) at either video or PC (and either works fine over HDMI), so it's not as simple as you seem to think. (The difference between DVI and HDMI is only in the connectors and in the fact that HDCP is optional for DVI and mandatory for HDMI.) |

What is quite funny - AVI infoframe provide required information that source output video with Full or Limited Quantization Range and customer shall be not even bothered for such problem - however drivers are written sometimes by people without any HW experience - then you have problem and real headache... Quote:
excerpt from HDMI specification: "6.6 Video Quantization Ranges Black and white levels for video components shall be either “Full Range” or “Limited Range.” YCBCR components shall always be Limited Range while RGB components may be either Full Range or Limited Range. While using RGB, Limited Range shall be used for all video formats defined in CEA-861-D, with the exception of VGA (640x480) format, which requires Full Range." This is quite straightforward definition or i misunderstood meaning of the word "shall" Last edited by pandy; 11th December 2012 at 18:00. |

There are a number of reasons for what you've seen and it depends on the setup at both ends, as well as the test pattern used, to explain it. |

If you try to give advice then you should be sure you understand what is done in the real world and give advice based on that, not just on a spec. Last edited by jmonier; 11th December 2012 at 18:32. |

Yes. E.g. "Ctrl+Alt+Numpad1". Quote:

I strongly believe that the GPUs should offer an option to let the user choose whether to output Limited or Full Range. AMD has such an option. Intel, too, I think, although I've been told that the Intel option doesn't always work as expected (it seems to be reversed or something like that). Only NVidia doesn't offer this functionality. But at least there's a registry hack available to make NVidia output Limited Range RGB over HDMI. |

The majority of new displays now support Full Range over HDMI, and some TVs like my Sony sets, even send the correct information to a PC to enable full range support without needing to change anything. (no driver/registry editing required here, it outputs 0-255 over HDMI automatically) |

I think EVR does the copy as well, because it doesn't really require any extra buffers. But you can always avoid the copy with LAV.

I'll throw in my anecdotal 2 cents.
I recently got an LED LG. I'd been running my Radeon HD 5670 with YCbCr 4:4:4 connected to an old LCD LG. madVR was set to defaults (except scaling). With the new TV, colors were horribly washed out watching US cable TV (Ceton InfiniTV 4, Windows Media Center). I then set the 5760 to use Full RGB and TV viewing improved greatly. But when I played a few videos via MPC-HC, blacks were crushed. I poked around madVR, deleted the display device that was installed with it(?), and set the LG to "expects TV levels (16-235)" et voila! AVIs, mkvs, etc., all looked much better. The effect was similar to setting the LG's Black Level to High (which normally washes them out). But that's a PITA, as it has to be reset to Low for TV viewing. So, in short, I love madVR, esp. running Jinc 3-taps with AR for chroma and image (software decoding in LAV via a Core i5) |

But I'll try your method to see any different anyway. Thanks |

Gotcha! And it also supports "=" for frame rate and movie dimensions automatic profiles conditions so my evil plan is bound to become reality
There's only very slight issue, though...it's that post-scaling PS scripts seem to be processed pre-, that's build 34665 with EVR CP: and now 34821, also with EVR CP: same goes with mVR, but I've notified them about the issue and I'm not entirely sure whether gamut mapping should be processed before or after scaling.......yesgrey told me ages ago that it would be preferable to work on the right colors ASAP but madshi seemed to disagree, and I would guess that in 32fp/16int, it prolly wouldn't matter IRL anyway JanWillem isn't very clear about what scripts would be better used pre- or post- either, so that doesn't really help. PS: they've acknowledged the bug in PotP and it will be fixed PPS: if you want the script to be used in PS 3.0, you need to add this on the very top of it: Quote:

madVR icon not appearing during playback
Hi,
Not sure if this is the right place to post this... but I'm currently trying to configure my videos to playback using madVR. I'm using LAV splitters. I've tried both PotPlayer and MPC. Basically, I can select madVR as the video renderer and play the video with it in both players, but the madVR icon never appears in the taskbar during playback, thus I'm not able to configure any of the madVR settings. The default appears washed out and lacks processing. My OS is Windows 8 Pro. Any ideas about how to fix this? Thanks! Last edited by orangedude; 12th December 2012 at 00:06. |
