I've been using ArgyllCMS for quite some time now.
What is the benefits of using madTPG over the built in one? P.S Over a long email exchange sending back and forth huge Verbose calibration reports, and receiving new fixed beta versions. Graeme Gill managed to fix the Black Input Offset problems when calibrating to BT.1886 standard (in fact anything with the -f0 command). Expect new version soon.

dispcal -P 0.5,0.5,2,2 -v -yl -t6500 -f0 -G2.4 -qm bla I'm pulling the trigger on a 2GB HD7850, hard to refuse for 110€ shipped with some serious cooling too It's only barely slower than a 660 so that should be the bee's knees with mVR for quite a while, I'll reconfirm |

http://madshi.net/madVRdeband.rar You can toggle it by pressing Ctrl+Alt+D, or by using the file name tag "deband=low/high". Not available in the settings dialog yet. FWIW, this test build also has a nice improvement for FSE mode, where rendering times don't decrease, anymore, when the backbuffer queue is full. In older versions a full backbuffer queue somewhat slowed rendering down. Not anymore (only Vista+). Quote:

You'll need to have D3D9 installed and updated to the latest version. IIRC it's not installed by default, at least not with all helper dlls etc. Quote:

(2) You run everything through the same pipeline you later use for video playback. This way there's no potential difference (in colors, levels, whatever) between the test pattern generator pipeline and the video rendering pipeline. (3) You can run ArgyllCMS on one PC (e.g. your laptop) and madTPG on another (e.g. your HTPC). Such a remote calibration works automatically with madTPG, if you allow the network communication to pass eventual firewalls. With ArgyllCMS' built in test pattern generator you must run ArgyllCMS and the test pattern generator on the same PC, which can be bothersome, depending on your setup. Quote:

As I have already mentioned, I am not a fan of BT.1886 (on my IPS 870:1 monitor). I can see compression artifacts on black steps 0 to 3 (out of 255), on the purest blu-rays like The Hobbit. Looks like random noise or squares. For me BT.1886 is much too aggressive on my Dell U2410 poor Contrast Ratio. On the other end, The better the monitor contrast ratio, the better and closer BT.1886 calibrated "Flatpanel" will look like a good CRT. IMO™, anything below 1000:1, stick with Power law + BLC. Cheers. Last edited by James Freeman; 3rd October 2013 at 19:02. |

The problem was the -f0 raised my native blacks from 0.23 to 0.29 (after calibration) thus destroying the contrast ratio (same with L*). Now my contrast ratio stays native like the values I see on the "Report Uncalibrated Display" log. I'll quote one of the mails: Quote:

For now I'm doing test on Windows 8, so I suppose D3D9 is up to date on this platform... |

I got a new laptop with a GTX 760m, but I found out that I cannot change the graphics processor to NVIDIA for media player classic, because that option is greyed out (whql 327.23). how can I solve this issue?
edit: managed to change it with nvidia inspector, I had to change the "enable application for Optimus" setting to Value "SHIM_RENDERING_MODE_ENABLE". Now I can change all the sub-settings as well.

regarding the nvidia settigs. its been said that leaving everything to default should be recommended. but what about the setting texture filtering quality? shouldnt that affect the image quality of movies as well? its set to high as default/global, but can be set to very high.
does this indeed improve anything? in combination with this trilinear optimization can also set to off for best image quality. also, something I noticed is that when I use CUVID in LAV Video as Hardware Acceleration, then my GPU and my CPU usage both is lower (according to task manager and nvidia inspector) than when using no hardware acceleration at all. Can this be right? Shouldnt at the GPU load be higher, because the NVIDIA card is being utilized with LAV Video and madvr at the same time then?

Deband works well here with some quick tests is there a way for it to save it's state?
What is F2 save icon when toggling deband? Speaking of keys ctrl+j conflicts with a hardcoded potplayer key (open webcam), ctrl+alt+j has no conflicts.

so definitely worth keeping active even on 10bit content which may not suffer as much from banding but still has encoding artifacts that will be improved with having this enabled. I find the high setting is a little strong for my tastes, is it worthwhile to implement the improved (more demanding) algorithm option with the low setting as well? Quote:
I too would really like a build where this setting could be saved we'll just have to use the filename tags for now. Last edited by ryrynz; 4th October 2013 at 10:57. |

Not sure: Is that irony, or did you really expect better? Comparable to your favorite f3kdb() settings? Or better/worse? Well, for good quality content it is probably too strong. But it can be useful for really bad content, especially for Anime. With Anime usually image edges are very sharp while non-edges are usually rather flat. So even in "high" setting there won't be much (if any) detail loss. I could probably even add a "ultra" setting for Anime with even stronger debanding. But I guess "high" should do the trick for most situations already. The improved algorithm consists of 5 checks instead of 1 check. The "high" setting has all 5 checks in it. The "low" setting still has 4 checks in it. So it's still improved over the original f3kdb() algorithm. But I've removed the 1 check which consumes most of the performance. That cut the rendering time in half. With the test images I can't really see a difference between having this 1 check on/off for the "low" setting, so I believe cutting the rendering times in half is the better solution. |

I guess with a GPU upgrade coming soon, I wouldn't mind chucking extra GPU at even a small increase in PQ. Would you entertain me a build with the fifth check enabled on the low setting? I'd understand if you'd dismiss it.. Maybe one that includes the ultra setting too? BTW your low setting isn't that far off the detail retention of my flash3kyuu settings. It's a bit softer but it does a better job overall.. I can honestly say I'll be moving flash3kyuu out of the Avisynth chain. I like that a lot because now I can deband 10bit content without dropping down to 8bit. Pretty cool.. I'm going to watch my first MadVR debanded episodes tonight. |

As I wrote above, sometimes madVR incorrectly changes or, on the contrary, doesn't change monitor refresh rate. Is it possible to add the possibility to change refresh rate from madVR's tray icon menu manually?

Also, the debanding works well here, but I think I'm getting some kind of spike in rendering times (default: ~14ms, spike ~154ms) every time it is activated from its disabled state or increased from low to high... I suppose that is expected? Just to be clear, I get maybe 1 or two dropped frames because of this, if at all, and the rendering times do go down again relatively fast, I just want to make sure it's not a bug. |
