madshi, for ~24fps on ~60Hz (fixed panel), I am still experiencing an issue where the video can look perfectly smooth, but if I seek and re-play the same part, it will be juddery (always a constant pattern) looking.
Is there be anything that I can do? Last edited by namaiki; 8th August 2010 at 11:37. |

1. As I said before we have a prove (DVBViewer's exclusive mode) that there is way to be "on top" of everything and no other window can show up over the rendered picture. And there is absolutely no flickering in this case. 2. Personally if I have to live with any kind of flickering I'd prefer the flickering to be in a small part of the screen than the whole screen as that's the case when going out and into exclusive mode. Usually the offending windows are some notifications (mail, instant messengers, volume OSD (OS's not player's)) that pop up during playback and disappear quickly afterward. I think ... if possible at all ... it will be great if you can distinguish between player's windows and windows from other applications and wait ... let's say 5 seconds ... before madVR goes out of exclusive mode if the offending window is not from the player. |

Like, in my case, the problem that i canīt get rid of is that after setting a custom timing, the NVIDIA control panel simply refuses to show the just configured timing (after I hit apply in the custom mode window) in the "Resolution" list, which means i cannot select it and "apply" it afterwards. It only shows the defaults, which are 59Hz or 60Hz, which is completely useless, since there already are PC modes with exactly those timings. Also, the NVIDIA control panel has some annoying bugs, e.g. on the "Adjust desktop size and position" tab, when switching to something lower than your native resolution, the NVIDIA driver panel just ignores what you just set it to and resets either to "Use NVIDIA scaling" or "Use my displayīs built in scaling", instead of "Do not scale" (which is my prefered setting). On the other hand, with PowerStrip, I can select every timing available for my display, ranging from 23.75-30.5 Hz to 47.5-61 Hz, I can set every resolution (non-native, unscaled) and it works perfectly and reliably in combination with madVR and every NVIDIA driver I have updated to in the last months. With PowerStrip, you are completely independant of the provided drivers, when it comes to these adjustments, and with madVR, you are also completely independant of driver bugs, when it comes to image quality in videos/movies. Hopefully, with coming madVR revisions, there is a way to read out the EDID data (DVI and HDMI) of the monitor and let madVR also have e.g. an "inf", where you can set your prefered timing according to the supplied "source fps". If this would be the case, madVR could also be completely independant of third party tools, but Iīm just thinking out loud. |

I don't think it's possible to get 24/1.001 out of a PC video card. Even if you use the correct CEA timings you won't get it or 24.000000. (the timings are the same) Quote:

Out of interest, what kind of display are you using? I think it might be an issue with HDMI devices that are not 100% compliant. |

EDIT: After further testing, the control panel wonīt accept e.g. 29.970 or 23.976 ("Test failed. The mode "xxx" is not supported by your monitor."), even tough I can set both modes using PowerStrip. Currently Iīm using an EIZO CG243W, which is connected through the supplied DVI-D cable to an NVIDIA GTX 260īs first DVI-port. The NVIDIA control panel also shows up my monitor name correctly "EIZO CG243W", but I cannot get it to switch custom modes through the panel directly, no matter what I tried.

Hello, everyone!
Have some questions, mostly quality-based... First of all, would like to report in about my DVD@madVR@win 7 experience. It's possible to watch DVDs if you install DScaler MPEG2 decoder+it's IVTC mod. As I was trying to open DVD, it (DScaler...) loaded up by accident (do not ask ) alongside ffdshow and the DVDs are working flawlessly with madVR! Also, seems to me that 0.25 has the smoothest playback of all renderers. Could that be because of the 'exclusive fullscreen mode'? The madVR's seek bar is not working for me though (I have MPC-HC's D3D mode turned on - may that be the reason?) But here are my questions... 1) Will there be implemented native DVD (problems with DVD Navigator@win7 mentioned earlier in this thread) support in madVR? That would be great because then it would be possible to use just ffdshow. Cuz, I'm worried if 'DScaler+ffdshow' doesn't somehow degrade the quality, because there is one more color space conversion (I'm unable to configure DScaler MPEG2 decoder - it outputs YUY and then ffdshow has to convert it to YV12). 2) Do I need to turn on or off the 3dlut option? (I don't use/don't know how to use gamut/gamma correction - so do I need 3dlut?) 3) Can you somehow easily explain differences between the timing models? 'Normal' is the only one working for me. It works great, but the other two gives me a big video/audio asynchronization (video too late/too soon) 4) Can you recommend anything on quality purpose. What I mean, is, madVR is with no doubts the best renderer there is. But what about other stuff? Like, decoders - is there any difference between, for example, ffdshow and CoreAVC or mpc-hc implemented filters other than performance? Color space conversions, deblocking, IVTC, etc. And what about players? I really don't understand much about how the video is becoming from a file to a picture on my monitor, but I'm all about quality, so I'm asking for your help. P.S. My config MPC-HC x32 + ffdshow + madVR (always the newest builds) + temporarily (<--- I hope so) also DScaler with it's IVTC mod (avsforum) Win7 Ultimate x64 Aero on ATI 4650 CRT@60Hz madVR - 3dlut on, exclusive fullscreen mode on, upload frames in render thread, show seek bar, timing model - normal, 8 backbuffers, don't flush anything, all resizing set to lanzcos8 Looks great on my oldschool CRT Last edited by desert.katz; 8th August 2010 at 14:09. |

You are going to have to expand on this. With Powerstrip there should be no problem getting 23.976hz, or a multiple thereof (I use 95.904hz). Last edited by Mark_A_W; 8th August 2010 at 14:36. Reason: Typo.. |

Luma upsampling: SoftCubic 50 Luma downsampling: Lanczos. I use 4, 8 is too slow. Not sure which is better. Chroma upsampling: Bicubic 75 Lanczos only looks good for downsampling, it is horrible for upsampling. Lanczos 3 is best if you insist on using it to upsample. If you want one of the sharper upsamplers, I would use Spline32/64 instead. SoftCubic50 looks best from my own testing though. It does not bring out compression artifacts like other upsampling does, and keeps aliasing to a minimum. Quote:
Here are the correct timings to use: http://forum.doom9.org/showthread.ph...66#post1318766 Edit: I am not meaning that it is an issue for smooth playback, but I would not recommend disabling resampling in reclock and forcing it to run at the original sample rate because the clock will not be perfect. Don't use its v-sync correction, but let it resample the audio. (preferably upsampled too) Some bluray is 24.000 on the disc anyway, its not all 24/1.001. Resampling everything to the proper 24.000, especially if you have PAL content, makes more sense. Last edited by 6233638; 8th August 2010 at 14:58. |

Most content better fits to the 59 refresh rate. It's not really 59.000Hz, it's actually 60.000Hz / 1.001, which is about 59.940. It's just named "59" because the names usually don't use floating point and 59.940 is lower than 60.000. Quote:

madVR v0.26 released
http://madshi.net/madVR.zip Code:
* fixed: windows on primary monitor were seen as covering secondary playback * fixed: when starting in fullscreen mode, madVR's seek bar didn't work * fixed: starting ZoomPlayer in fullscreen exclusive mode made problems * when "maximizing" the media player, exclusive mode is activated at once now * exclusive mode switch is now done after 3 seconds instead of 1 second * while exclusive mode is active, media player window is made topmost now * windowed tweak "timing model" is now used for exclusive mode, too * changed Aero timing mode once again * added forced OSD display "windowed" vs. "exclusive" when switching * new interface allows media players to ask whether madVR is in exclusive mode (1) Loading the video file on primary monitor, then moving the window to the secondary monitor confuses the automatic fullscreen exclusive mode. Requests: (1) Please report if there are any problems left, especially with automatic fullscreen exclusive mode. If you do still have problems, please report your GPU, OS, monitor setup (1 or 2 screens, playback on primary/secondary etc) and media player. (2) Does anybody absolutely need the "aero" or "high refresh rate" timing models? If nobody says yes, I'll remove them next week and always use the "normal" refresh rate. |

Yup. I have Aero enabled, so I use the "aero" setting. And it seems to work fine for me...

Ok, but do you actually *need* it? Could you please try if the "normal" timing model maybe works just as fine? I'd really like to get rid of the timing model option to make the settings dialog easier. |

Or are there problems reported with Aero enabled + Aero model? (Didn't read the entire thread, it's just too long)

I just saw that the problem is only in Windows 7 - it doesn't show file version for .ax files !?!? What are they thinking in Microsoft? Why do they have to break such simple things that work perfectly well in XP Quote:

No, that's far from what I'm saying. If suppose it's not possible to prevent other windows to go on top of madVR in case of a temporary pop up window I'd prefer to have a small flickering for up to 5 seconds (an exemplary timeout I mentioned in my previous post) than a whole screen blinking in both transitions out of exclusive and back to exclusive if the other window disappeared. And after that time if the window didn't disappear and is still trying to be visible madVR should go out of exclusive mode. If it disappeared then everything should continue as it was - just with a small glitch. Last edited by pankov; 8th August 2010 at 20:52. |

ZoomPlayer's main window is not "topmost", while MPC HC's main window is, when they go (windowed) fullscreen. Maybe that's why you've seen many windows covering ZP. But that's not really madVR's fault. Anyway, madVR v0.26 now hacks the media player to be "topmost", as long as exclusive mode is active. That may improve the situation for you. Quote:
