Note that you can also do this by changing a few lines in your profile's .ini. I wasn't aware that Overdrive could affect 2D clocks.

First of all, treat 25fps as 23,976 option in madVR will not work in my setup. This is because I ONLY bitstream and if I am correct this function only works when you let the decoding by done by the HTPC. I ll explain exacly what I want to do so you can tell me if this is possible or not: 80% of the content I play is 1080p@23,976. That why my standard ATI setup is 1080P23 (ATI 23=23,976). 15% of the content I play is 1080p@25,000fps so what I want is that with this content madVR let s my output switch to 1080p@25Hz. The rest of my content (5%) is tv-shows material and movie trailers. These can be anything like 59, 29, 24Hz. For this content I would also like that madVR tells my videocard to switch to the best compatible output res.+freq. What i DONT want (and which I ve read on some pages) is that madVR switches my video output to 1080p@24 for 23,976 material or 1080p60 for 25fps material. Pitty that MPC-HCs own changer does not work with madVR because this is very finetuned. |

Have you actually tried it yet for your various sources? Does your monitor actually support 25Hz? Remember, do not set a refresh rate in madVR that your monitor will not support.
Why don't you just try it and report back what you can't get working? |

I had set it to present 10 frames in advance and that worked. 8 didn't work, and the render queue still dropped a bit, and the present queue slowly to zero again. At 10, present stays 7-9/9 for the most part. But then I just noticed that playing 24p content when switching to exclusive mode, the damn silent stream bug hits and I have to wait 1-2 seconds to hear sound again... Not so when presenting lower number of frames in advance, like the default 4. So just to see what would happen, I decided to make it 2, and surprisingly the render queue stays solidly at 5-7/8, and present queue at 1-2/2 without dropping to zero at all. I then tried 3, and it also works, at 5-7/8 and 2-3/3 respectively. After that, so far so good. |

I`ve recently upgraded from my old GTX260 (which served me very well and madVR ran great with it) to a shiny new GTX570 which is almost silent. (ASUS Direct CUII cooling, I am quite impressed). What is surprising for me is that madVR still runs great with the same settings I used for my old card and even the same drivers (newest quadro or geforce beta 285.38, both run great).
I didn´t expect this since I was getting the impression from reading this thread that newer cards have some unusual problems. madshi: Like you already wrote in this thread, the D3D11 path also works best for me (23.976fps or 24fps@24Hz). However, it would be great if you could improve it to the point where going out of FSE mode to windowed draws the desktop each time. Currently, after you start playback of a file, switching usually works 2-3 times but stops working for no reason and then starts to work again, etc. It is quite random. Switching works in every other mode or path I´ve tested, so there must be something weird going on specifically when you enable D3D11. A workaround is to pause the file and switch when in pause and then start playback again. Other than that madVR is smooth as butter and I wouldn´t trade it for anything else.

Can someone tell me the advantages of using DX11 and/or Exclusive mode in madVRs options?
I get very choppy playback (but no difference in CPU/GPU load) when I enable exclusive mode. Using LAV Filters with CUDA and GTX460 together with MPC-HC.

1. The projector is hard calibrated in such a way that the gamma, gamut and white point are adjusted correctly. In this case, just choose “this monitor is already calibrated”. 2. The projector is hard calibrated in such a way that the gamma and gamut are adjusted, but the white point is not. In this case, determine your projector's white point and calculate a chromatic adaptation matrix, then load that (as .3dlut). 3. The projector is hard calibrated in such a way that the gamma is adjusted, but the gamut is not - in this case, the gamut will be profiled (eg. as ICC profile), and gamut correction has to be calculated manually (eg. with a 3dlut or the built in yCMS option) 4. The projector is not hard calibrated at all, but contains a soft calibrated gamma (CLUTs) along with an ICC profile (the two are usually combined into the same file). In this case, you will need to fix both gamut *and* gamma using a 3dlut. I don't know which of these is the case for you as they're all valid solutions in practice, and all just as common. Personally, I use option 4 because my projector/monitor does not support hard calibration (well, it does - but it only includes a few hard calibrated options - in particular sRGB, for which it is option 2). Edit: It sounds like the ISF calibration just fixes the white point to be at precisely 6500K (which is also incorrect, incidentally, but I trust that the “professional” doing your calibration knows this) - I don't know how well and to what standard your gamma is calibrated and I don't know anything at all about your gamut. Do you know if your calibration has performed this additional task and how well? Is there something like a calibration report that he gave you? I'll have to do some research on your projector. Edit 2: It sounds like you have at least a “THX Mode” which is supposed to be (in theory) calibrated to 2.2 PPC, D65 and BT.709. Can you confirm how many color “modes” you have, and which one you are using?

Why is 6500k incorrect?
BTW, I've tried to use madVR/yCMS for my setup (running a CRT projector, measuring with HCFR) and the results are not good. There seems to be a bug in the system somewhere, the whites are fluro green. Options 2, 3 and 4 are not for the faint hearted/newbie..... |

Input: 8 bit integer, channel order: BGR, color space is the tagged input primaries (the ones in the meta data), gamma is 2.2 pure power curve, limited range, with chromatic adaption to D65. Output: 16 bit integer, channel order: BGR, color space is your monitor's, gamma is your monitor's, limited range, with chromatic adaptation to the display's white point. Edit: Forgot to answer your question, D65 is in fact approximately 6504K, not 6500K.

It's possible I made a mistake (there was one mistake I have corrected), as the direction of rows and columns is different - it's a painful process. What I am really trying to say, is this is not easy, and frankly I'm not aware of anyone getting it working properly (correct me if I'm wrong.....PLEASE!!). Oh, and 6504k vs 6500k....um....really? Even 6600k or 6400k are basically invisible to the naked eye without a reference....unless you are leeperry My CRT projector's response is messy (even with hours spent tweaking the colours with HCFR and Gamma on the PC...it's...old..) and it still looks fantastic. |

What do you mean by that? My HCFR was calibrated against a calibrated Colorfacts with the expensive Eye One sensor. It gave basically identical results - certainly good enough for me, and fantastic for $100. |

That is, at 16-bit scales, 65544.7254082441436595 / 65533.967607934659915 / 65516.5643188505533428, a difference of 1-20. Regardless of whether or not you can see it, it's a notable enough margin when calibrating a 16-bit gamma curve.

But its error is larger than +-4K at 6500K, it isn't a super accurate sensor. Sensors that are that accurate are very expensive. I am pretty sure the Eye One isn't. I am sure the HCFR is great for video watching and normal use but you don't need to worry about (and cannot differentiate) the difference between D65 and 6500K.

It was about A$5k. He is a professional calibrator, one of two in Australia (both my mates). Greytag Macbeth Eye One Pro or somesuch, I forget the exact name. The one you have to take black readings with constantly - it has a little shutter you close to do that. |

Short-term repeatability: x,y: +/- 0.002 typical (CRT 5000°K, 80 cd/m2) I am sure it is a great calibration system, certainly better than anything I have access to, but that is a very small difference. |
