If no hardware acceleration method is used like CUVID or DXVA, would that free up more of the GPU processing power and allow it to better handle JINC scaling?
Does it make sense to use the GPU as a pure scaler with the CPU handling whatever else is needed to decode? Could JINC or better scaling be handle in software (by processor) to do away with needing a powerful GPU? What kind of processor would be needed to do that? |

Zoomplayer 5.02 HD4770 Catalyst 12.4 Madshi,excellent build.The rendering times with Spline 4 taps have gone down dramatically.No frame drops,no glitches anymore.Quite a huge difference compared to 85.7,I must say. Is 85.8 heavily optimized? You mentioned a change in madvr's logic...Please keep it this way because the performance increase is really tangible. THANK YOU ! |

The regular 3:2 repeated frame method for 23.976 fps (anime contents) to 60 fps has an issue on my interlaced PDP TV (Hitachi P42A01A). It could show some content's vertical flicks with object's motion in the vertical direction. The video output mode is set to 1920x1080i60. I seldom use 1920x1080p60 mode since it degrades the visual quality on this TV --- obviously anti-flicking filter is applied. If I set the video signal to 1920x1080p23 (23.976 fps), the issue is gone. Since this TV's panel driving is still 1024x1080i60 for 1920x1080p24 input signal, I guess it does some tricks to prevent 24 fps content's presentation from showing such flicks --- without any visual quality degradation. |

Does anyone know how to calibrate correctly Black to Black and White to White levels?
I have a couple of test patterns, but Madvr info is detecting the range as "limited" and not "full" like it should be, so I cannot calibrate. |

Test patterns for Black and White Level always are marked as Limited Range, because thats whats the majority of all consumer video is. Wouldn't make sense to calibrate against something else, would it?
The only difference there is that the test pattern then contain BTB and WTW values, so you can calibrate your playback chain that you see 16-235, and not BTB/WTW.

Brightness: Disable any auto contrast options. Put up an all-black pattern and adjust the brightness control until the display stops getting any darker. You have found the correct setting when +1 brightness will visibly brighten the screen, and -1 will not go any darker. Contrast can really be set wherever you like. Modern displays shouldn't clip highlights when adjusting the contrast control, and blooming is no longer a concern. I recommend the default position or lower. (often 90/100 on LCDs) |

Sorry for the newb question, but I can't get the madVR control panel to launch on my machine in any player. I always get a message along the lines of "Make sure your firewall isn't blocking madVR". I'm on Win 7 64 bit using mostly MPC-HC 32-bit and Zoom Player MAX. I've registered madVR.ax as Admin, but Windows just can't find the file. Is there a hot key combination to open the control panel?

I'd recommend it as a good starter. The best way to build up some knowledge is reading a lot about it And let Google be your friend ! |

Of course, this was the ""easy" part : now some indication of all kinds of "judder" for the OSD .. Last edited by Pat357; 26th January 2013 at 22:00. |

For those that have the problem with the fading/stuck windows. Has anyone noticed this happen even more with recent releases?
I upgraded to the latest Madvr and Lav, and now the stuck windows happen even more! Sometimes my other monitor goes completely black even. *Edit I am also receiving a lot of crashes in MPC-BE related to madvr. Anyone had similar? Last edited by Dodgexander; 26th January 2013 at 22:24. |

I have similar problems when using dxva2 decoding. If I open a new file while playing a video in fullscreen exclusive mode on my secondary display, I often get a black screen or a MPC HC (or BE) crash. With software decoding everything works flawlessly.
