i found a lot of posts asking about, in one madshi says to use the test paterns especialy the colours and try different bitdepths, and see what looks best, also i made the procediment to know if my display supports 10 bit (there is a thread about in the forum) i tested milion times 6bit, 7bit and 8bit now i clear see the diference in the patterns in my case bellow 8bit produce banding and above 8bit i can see more banding and seens that the images has no dithering after all of this i calibrated my display with dispcalgui and on iccprofileinfo was showing 8 bitdepth

But I doubt you will see a difference outputting 10-bit on a '8-bit + FRC' panel vs properly dithered madVR output on 8-bit panel. On a side note, did anyone with a '8-bit + FRC' panel make some tests displaying 10-bit with madVR with dithering disabled to compare panel's dithering to that of madVR? And, is madVR's Ordered dithering enough to smooth out the gradients of a dithered 10-bit on a 8-bit panel or is Error Diffusion required? |

i don´t find any specs about my panel searched everywere,i don´t know if has FRC i know that if i go d113d exclusive 10 bit with any dither algo the image is similar to 8bit with dithering disabled on madvr

In your case the file is h264 10bit and madvr gets 10bit color format from the decoder. This is good because it means madvr does the dithering to 8bit before sending it to your display. This gets you higher quality than decoder's dithering. Quote:
Another question is whether the studio used 10bit while mastering the source, which usually isn't the case. Quote:
That said, you should have dither always enabled. To sum this up: when in doubt leave the settings at defaults to get highest quality. 10bit videos on 8bit displays should look so close to 10bit display that you can't notice a difference. Your settings are alright, so don't over-think it, just enjoy the movies |

http://madshi.net/exc-ss3.gif If so, click on "show bug report", then press Ctrl+C. After that you have the crash report in your clipboard. Upload it somewhere for me to look at. If the crash box looks different, it's probably a crash in the media player (or decoder or splitter or ...) and not in madVR. Quote:

The other sharpeners all concentrate on edges, only, and intentionally leave non-edge areas untouched. So the "enhance detail" algorithm basically works on different image regions compared to all other sharpening algorithms. Quote:

Basically this means that we have to take ambient light levels and that kind of stuff into account, too. [QUOTE=Stereodude;1750030]I've come across a few scenes in some NTSC DVDs where the madVR IVTC algorithm freaks out and drops the 3:2 pattern and goes unknown before recovering when the shot changes./QUOTE] Quote:
Quote:
Blu-Rays are usually encoded to BT.709 primaries. NTSC DVDs are usually encoded to SMPTE-C primaries. PAL DVDs are usually encoded to EBU/PAL primaries. In theory, in order to watch all these 3 different sources with correct colors, you'd have to calibrate your display 3 times with 3 different presets, one for each of those gamuts. I don't think anybody is doing that, not even professional calibrators. Most displays these days try to get near to BT.709. Most calibrators aim to achieve BT.709, too. If your display is calibrated to give you correct colors for BT.709, then Blu-Rays will look correct in your setup, regardless of whether you set madVR to "disable calibration control" or "this display is already calibrated". However, if in this situation you play e.g. an NTSC DVD, there will be a difference. With "disable calibration control" disabled, the content will be sent to the display as is, and the colors will be slightly incorrect. When using "this display is already calibrated to BT.709", madVR will convert the NTSC colors to look correct on a BT.709 calibrated display. So basically the recommendation is the following: If your display comes close to BT.709 (either by factory, or by manual calibration), then you should use "this display is already calibrated". If your display is not calibrated at all, then the colors you'll see are likely to be incorrect in any case. In that situation you could just as well use "disable calibration control" because there's no way to achieve correct colors, in any case. The difference between a properly calibrated display and a non-calibrated display is probably much bigger than the difference between BT.709 and SMPTE-C. Quote:

And higher refresh rates are becoming increasingly common. There's an ever-increasing number of TVs which support 120Hz inputs now, and I don't know anyone that's bought a new monitor in the last few years which wasn't 120-144Hz - and the latest models now offer 165-200Hz. (and that 200Hz monitor is a 21:9 "ultrawide", which seems to be gaining popularity) It's less common with higher-end home theater equipment like projectors - though there are some 120Hz DLPs, but there should be 4K120 displays on sale next year. I just hope that LG or Samsung OLEDs are a part of that. |

madVR is more meant for big TVs and projectors. I'm not going to invest time into BFI if it mostly only works on computer monitors. IMHO we need at least 96Hz before madVR BFI can start making sense, ideally 120Hz. The number of users with such TVs is probably very low atm. Furthermore there's no way for me to test this properly without having such a high-refresh-rate TV or monitor myself, which is currently not the case.

I'll take a good look and try to see the difference, but I didn't see at the first time. Quote:
What's your laptop? And what string of the display can you see in madvr under Devices? (I need the full string) Mine is: LG LP156WF1-TLF3, and panellook reports it: http://www.panelook.cn/LP156WF1-TLF3...iew_12274.html

When I play it on another PC and use Quicksync as the HW decoder madVR only finds a 2:2 pattern which AFAIK means it is pure progressive. HW decoding with CUVID also leaves a 3:2 pattern for madVR to find, like SW and the Radeon HW unit. |

Do my calibration settings in dispcalgui i thought the correct was use the already calibrated to bt 709 with pure power curve transfer function but testing the hdr content i only achieve goods resuls if i set the bt 709/601 curve could someone explain the difference between the the two transfer functions? There was a shader in sweetfx that simulated the appearence of HDR, was terrible because even in the minimal seetings the black were so darker e the withe so brighter that vanishes a lot of elements in the darkker/brighter areas tweaking madVR i achieve the same results setting the transfer function calibration to bt 709/601 and setting gamma processing to pure power curves(terrible results, i was only messing the gama to see what happens), so i wondering what the difference of the transfer functions and in what cases should we use then? iits possible to a tv or monitor were calibrated to bt 709 with pure power curve? what should correct? in dispicalgui there´s option to use bt 709 tone curve or gama 2:20, what should the correct transfer function to work properly on madVR color conversions?

I serchead so many time for some information/specs about that, but didn not find anything relevant (i had hard times to do a correct calibration profile for use with madVR, i fid a lot of people in foruns complaining about the colours of this display, some people sayng that is wide gamut, so i searched a lot, but with no results, the colors are a bit saturated but i do know nothing about, found that are different versions of this panel that came with lenovo, acer and hp laptops, but in my case there is no documetation about, so i don´t if is v1, v2, v3,v4,v5 http://www.panelook.cn/rfqs_cn.php?p...2%82%ACB156HW1 tried to search AU Optronics KYYVK-B156HW1 too, because dispcalgui reports that way just not informations at all, if you help me to findi will be very glad edited searched again and found but that are 8 versions on the site, thanks a lot! but i still don´t know what version is my... http://www.panelook.cn/modelsearch.p...umber=B156HW01

if you use this option for HDR than the results are different. it's like madVR wants to take these settings and change it back to normal gamma 2.2. that's why changing to BT 709/bt 601 curve is crushing black or at least rising the gamma and a higher gamma is lowering the gamma. but "color & gamma -> enable gamma processing" does nothing with HDR content. "correct" would be a pure gamma curve of 2.2. if you are using DISPCAL GUI just think about an 3D LUT. |

Edit: Now thinking about it, I can see why "delay playback start until render queue is full" would not fix the problem since it is a decoder queue problem. Would it be possible to add the option of something like "delay playback start under decoder queue is full"? Last edited by Aktan; 19th December 2015 at 17:28. |

I have a computer which I use for amature photo editing at home and it's calibrated with i1 Display pro and basICColor (it generates an icm file which is loaded by Windows at startup) Just today I found out about dispcalGUI and Argyll CMS. Since I also watch movies on this computer, what's the advantage of dispcalGUI over my existing calibration besides the 3D LUT? Is the current movie playback with MadVR using the .icm of the existing calibration?

I'm surprise it finds a 2:2 pattern at all as I thought that is usually used on PAL DVDs. But it is interesting that 1/3 of the time when I force FILM deinterlacing from madVR, I do get a 2:2 pattern as said by the OSD.

Yes, I am using DXVA upscaling, but when I use any other upscaling with this video (using last versions of MPC-HC, XYSubFilter and MadVR) I don't get any image at all. The sound plays fine but the screen is black. With some of the upscaling methods I can see the info when typing Ctr+J, but in most cases I see nothing at all. All the upscaling methods work fine with other videos that I have tried. How I can create the sample? I took a sample with Avidemux but it ignored the subtitles. Then I extracte d the subtitles from the original video and I added them to the sample. But something is wrong. Selecting DXVA upscaling it was possible to reproduce the problem: subtitles not upscaling and appearing in a wrong position, but when I tried Catmul-Rom on the sample the computer crashed. |
