Hi,
Previously, using MadVR with my TV refresh rate set to 23.976hz on a ATI 4550 (with Windows 7) I was getting stuttery playback with Aero enabled, and tearing about a fifth of the way up from the bottom of the screen with Aero disabled. I've just tried the latest MPC build, and using MadVR (with default settings) with Aero enabled I get smooth playback. The first few seconds are stuttery and it drops a few frames, but settles down and the rest of the playback is super smooth with no more dropped frames (with Aero disabled I still get the tearing). Would someone be able to explain to a simpleton like me what exactly Aero does to remove the tearing? And whether something has changed with the latest MPC build to improve smoothness with Aero enabled? |

How is this not the #1 thing to fix? |

@X-Dron: I think your problem is glasses: you have forgotten to put your 3D glasses, that's all !
@somy: I can't really say more things. I have similitudes with iSeries: - tearing if I disable Aero (dual or mono screen, all EVR and madVR); more tearing for 24Hz, just a bottom line in 50Hz - In 24Hz in dual screen, with Aero enable, windows Seven is... lost; cursor is really slow, and even if EVR graph could let me think it's judder free (perfect parallel lines), there are major jerks. Just try to move your mouse, if cursor is not smooth for 24Hz screen, then you'll know you can't use Aero (just right click on mpc-hc.exe and disable desktop composition in properties) - in dual screen, 50 Hz, Aero enable, no more slowness when moving mouse, but you still have judder (not shown by EVR graph, except if you put a 30fps video, you'll see graph freezes) - in dual screen, 50 Hz, madVr + Aero... Same behavior. Judder caused by Aero :/ - in mono screen, it seems to be ok with Aero, even in 24Hz. In conclusion, if you use dual screen, IMO, you have to disable desktop composition (Aero) when launching MPC-HC. You'll have tearing, but we can guess it will be fix by future version of Madshi or ar-jar renderer (when they implement Direct3D) @iSeries: I think nobody really knows exactly what Aero does, but it's sure at 100% it prevents tearing. |

@pirlouy - our experiences are not completely similar. With EVR CP or Sync Renderer and 'disable desktop composition' (i.e Aero disabled) I get perfectly smooth playback at 23.976hz with no tearing. I'm just confused as to why, with the latest MPC build, MadVR works fine with Aero enabled whereas before I was getting terrible playback.

In my setup I have one monitor runs at 60HZ and I play movie on my projector as 2nd monitor which runs at 23.976HZ, EVR and MadVR is completely not watchable, EVR sync looks smooth, but it occasionally produce judder and the green line is not always in parallel with red line, it goes up then goes down then up again...... |

We will gladly switch once 24bit support has been added (its not on their to-do list)

Hi somy,
My TV is set up as a secondary display (set to 23.976hz). Using Sync Renderer with the target sync position at 30ms and 'Disable desktop composition' enabled, the green line is slightly wavy but parallel to the red line and no spikes. Playback appears to be perfectly smooth (I find watching the end credits scrolling a good test of smoothness). A longer test of MadVR with Aero enabled shows every now and then there is a stutter, but with Sync Renderer playback remains smooth throughout (please Madshi, update MadVR to fix the 24p tearing issue when Aero is disbaled ) Have you checked your settings in CCC? Playback can be affected by some of the settings in the 3D and Video configurations. |

i was talking only about libavcodec not support 24bit for the important audio formats.

I'm not aware that I have to set 30ms for 24P content, the default is 12ms I think. Anyway, MPC-HC now support switching refresh rate automatically, so I'd probably keep using Sync renderder for now until Madshi release new MadVR :-) Last week I also found the YUC/RGB conversion of FFDShow is not that bad comparing to MadVR, so I'll live with that for now. My experience with MadVR is completely different from yours though, in my case when Aero is enabled the playback is simply not watchable at all! I'll try to test it again with single monitor aero turned off and see how it looks tonight. Regarding settings in CCC, what shall I do? I know it won't use avivo, so I guess the setting there won't affect the result. However I'm not sure what side effect can be introduced by 3D settings.
