Madshi: Any chance that you would ever consider defaulting MadVR to a spline or lanczos scaler? Though I would guess, not without a good reason.. Last edited by namaiki; 7th May 2010 at 23:59. |

What I don't like about Lanczos is probably the result of ringing (I find it rings quite badly on luma, 4/8 are even worse) but it looks different when it's being done on the chroma. You can almost see it in that example actually - the red circle almost looks like it has a beveled edge when it's just supposed to be a flat red circle. And I agree that Bicubic 75 causes too much ringing for luma. I've only set it to that for now so that luma/chroma upsampling 'matched' but I plan on changing it. Then again I always watch content at its native (luma) resolution anyway so it's not really an issue for me. From the limited testing I did some time last year, I decided mitchell-netravali looked best for luma, but it was too taxing for my system and it was nearly impossible to do a comparison on the exact same frame. Now it should be much easier to evaluate because you can change the rendering on a paused frame. I haven't really seen any problems with Bicubic 75 on chroma so far at least, and it definitely produced the best results in 0.11 which surprised me as I tend not to like bicubic. What I can say though is that I actually like softcubic less than bilinear; that was also surprising, considering it's often recommended here, but it just blurs things too much. |

Is it possible that when refresh rate and frame rate are "compatible" (e.g. exact multiple) and depending on where in the cycle frames become available for presentation (random after each seek and drifting slowly over time, depending on how "exact" the mutiple is) this flush code might sometimes push availability one side or other of vsync? |

I'm only telling you what I see, and I can confirm that seeking with Reclock in 0.12 is still a major hit or miss, as it was in 0.11 |

hey, first ! I would like to thank madshi for his work.
On my config there's some points : I don't know why when I use Madvr there's so much cpu usage ? When I use Madvr with an h.264 file I have a cpu occupation of about 70% While with haali renderer I have a cpu occupation of 30% Why Madvr causes so much cpu usage ? He's supposed to do all the work with my graphic card ? The result is that I must overclock my little pentium dual core (2ghz) to about 2.5ghz to play the video without stutters. The other point is simply the stability when I start my video. Sometimes media player classic doesn't respond. Sometimes It does.... I've got a gt240 and I'm running seven. |

However, there is a very good chance the Reclock method should work too. I guess it depends on how much of your valuable time it would take to offer the option. I admit I have not done extensive testing with Aero, but certainly in exclusive mode Reclock should be able to set the point of presentation very dependably. With EVR sync, start of presentation is normally fixed +/-1.5ms. On XP occasional spikes due to delayed presentation of say 7ms are seen, but if av. point of presentation is set ~17ms for 50Hz and 12ms for 60Hz it is very rare, on a well configured PC, this actually causes a drop (mostly not even one per movie). On W7, with its improved scheduling even these spikes are not seen. So I'd say even if Aero needs more margin it is still likely to be fine. Reclock vsync control is really very reliable in a multitude of players including PDVD and TMT when using an overlay surface, as they do for Blu-ray playback. Here you do not even have exclusive mode to help you. Offering this advanced option would get around the possible current synchronised judder problem madVR may have, but more importantly it would let people like me who use Reclock vsync correction in PDVD/TMT for Blu-ray disc playback use it also for madVR. Alternatively, we have to use a .reg file to change Reclock settings before using each player to manually turn on or off vsync correction. But I understand it does depend on how hard this would be to implement! Last edited by Jong; 8th May 2010 at 11:43. |

please, do write an Aero solution, and if possible do it before the exclusive one. I'm begging you for this because the player that I use (ZoomPlayer) doesn't work good in exclusive (no OSD) ... and I think some other players will be affected in the same way too. |

Sorry, I mean for upscaling the defaults are very soft.
Thing is after you scale up a certain amount using the default scaler settings, blocks can be seen, but that of course depends on the content as well. default: http://img34.imageshack.us/img34/2494/defa43t.png something else: http://img263.imageshack.us/img263/3039/bicubic60.png Last edited by namaiki; 8th May 2010 at 12:46. |

Did you already try what 6233638 suggested? Does that make any difference whatsoever? Because he is also using reclock and has smooth playback with 0.12. @madshi: Iīm not sure if this is helpful but from experience (having had a CRT until recently before I got the LCD) there is one thing (consider it rather subjective, since 0.12 wasnīt released when I still had my CRT) that I cam across, too. With 0.11 I _never_ could get smooth playback on my CRT on any files, even when playing around a lot with my refresh rates. madVR dropped frames constantly. I have tested 0.11 again with my LCD and it seems that it behaves completely different than my CRT did (I had it connected via BNC, not D-SUB) re: a stable display refresh rate. Because when Iīm looking at madVRīs OSD my LCD only ever fluctuates at the very last 2 digits while my CRT had a hard time of keeping itīs refresh rate constant at all, it fluctuated like crazy. 0.11 even sometimes reported my display refresh completely wrong, at least thatīs what the OSD showed, so Iīm under the assumption that madVR could not calculate some things that it needs to display a smooth image. Just wanted to share that with you, not sure if that helps anything. |

Btw. here a picture with madVR stats from my system - tearing at 23.976hz. Its *always* in the same postion (i marked it red, because i can not screenshot the tearing), no matter if i restart the player, system, use pause, or whatsoever - madVR tears at this position for me and no where else. My system is a Q9550 + ATi 4770, on WinXP SP3, output on a JVC DLA-HD100 (RS2 named in the US) - btw my timings (with powerstrip) are very very tight - i get not a single Repeat/Drop (apart from the starting ones) while bitstreaming AC3/dts in 13+ hours constant playing. With other renderers i can adjust the vsync with reclock to not tear, with madVR its not possible, and after reading your conversation with jong i understand why reclock is not working the way i am used to be. I cross my fingers that the exclusive mode will fix it, it is a it strange that the tearing is always at the same position or ? |

I get exactly the same tearing as you at 23/24Hz with 0.12. I'm also on XP SP3 with an Nvidia 8600GT.
This seems to have been present for me since 0.10. Versions 0.9 and earlier were ok. If there was tearing then it was when play was started and a quick pause / play would fix it, similar to when I use VMR-9. |

I don't understand why people think aero is a good thing. In my experiance aero (on win7 x64) is only good in a single display set up, as soon as you have two active displays everything goes wrong with aero enabled.
I have found that aero requires refresh rates of both displays to be good multiples of each other, if not you'll get judder caused by aero thats not seen by the video renderer. For example if you play a 25fps media on a secondary display with 50hz refresh rate you will not get smooth playback unless the primary display also has a refresh rate at a multiple of 25hz. I have this problem with all renderers tried (haali,vmr9, madvr). |
