Actually this frame blending is exactly what many studios do when converting natively interlaced NTSC TV series to PAL (60i -> 50i). Motion is perfectly smooth this way. Quote:
I can't tolerate *noticeable* frame drops during a movie, either. I have no problem with frame drops, though, if they're not visible to the naked eye. Last edited by madshi; 17th May 2010 at 12:34. |

I dont think your goal contradicts perfect audio processing in any way.

I'm not after a bit perfect audio playback, instead I'm fine with a bit molested audio stream. So, currently I'm not planning to make the audio renderer perfect in the way that was proposed (I just don't have enough resources and maybe even the skills needed). I think a separate thread would be good since we are drifting away from the madVR into a more common direction. |

I think the only practical solution, other than resampling the audio (a la Reclock), is to fiddle the video timings. Stretch and compress the actual video timings on the card.
Ar-jar did this with gothplayer. He moved away from this method, I never really understood why, as it is one of the two possible solutions. That said, Reclock sounds fine to me. It's all whizzbangy and upsampling now. And Powerstrip is going the way of the dodo. The latest ATi cards don't support it, and I don't think they ever got the last couple of generations of Nvidia cards working properly, both due to insufficient info from the manufacturers. |

Yeah a new thread is possibly best, and as starla suggest, we need to think of scientific ways of measuring audio quality before we can do any coding in that area.
I suggest building a scientifically accurate test-suite for the video renderer too.

If the P-frame is encoded with insufficient bit rate, however, the picture loses its sharpness at all. |

But if refresh rate is tweaked correctly there is no need to drop/repeat for many many hours. Last edited by FoLLgoTT; 17th May 2010 at 18:09. |

I'm not sure how you would do without reclock though, bluray releases are a combination of 23.976, 24.000 and 25.000 fps, with the original source being 24.000. Reclock plays all three back at 24.000 and upsamples audio to 32/192 to minimise quality loss. |

I'm one of those people like starla who would rather have perfect video over audio. I don't like the sound of frame interpoliation no matter how its presented. LCD panel makers have been trying it for years and still havent got it right without artifacts or some form. Its one of the reasons I have gone off of reclock somewhat (though I still use it), the tool used to put video smoothness (judder) over audio. That was the entire point of the tool back in the day of gfx cards with TV out, and I'm not talking about DVI or HDMI. Since it got taken over from Ogg the program has become more turned to audio rather than video, not that its a bad thing but it seems these days the current devs are not intrested in perfect video as much as perfect audio. I just wish more effort was put into bitstreaming with reclock. I don't use reclock resamplers at all, for me the tool is best when bitstreaming, even the odd dropped or repeated audio packet every couple of minutes is no problem against the miniscule CPU usage it requires compared to resampling. Anyway, maybe i'm talking a bit much in the wrong forum about that.
For me the video rendering should be a priority over audio when it comes to watching content. The video renderer should not start adjusting the image to allow audio to be perfect. I feel that could be a slippery slope, espicially when audio is already getting resampled left right and centre. Btw, Im a person who likes the sound from vinyl more than CD |

Remember we are talking packet sizes of only 32ms for dolby and 11ms for DTS. Last edited by Razoola; 17th May 2010 at 21:35. |

sample and more infos needed, or it didn't happen...WMV play fine here. maybe a DRM'ed file?

many ppl who complain about Reclock resampling actually play their movies in DirectSound...which does the exact same thing, as DirectSound cannot be made bit-perfect on Vista/W7(unlike XP when all its sliders are maxed out ): http://www.hydrogenaudio.org/forums/...dpost&p=522247 I'm not trolling or anything, but teh "evil resampling" will most likely occur anyway(except for the bistream/pass-through ppl...but no 25@24fps for them then ), and quite frankly Reclock in its highest libsamplerate SINC mode does a hell of a job...conduct some proper DBT, tell us how it went and I'm quite sure that many ppl who are so proud of their bit-perfect audio don't EQ their room resonances down... terribly OT, but I think this sort of statement boils down to: -unbearable "loudness war" CD mastering...4dB of dynamics, great! http://www.dynamicrange.de/ -cheapo opamps in the CD players they tried , as a 4580/5532 will sound artifacty/agressive/edgy/narrow when two LT1028/AD4627-1/LT1363/OPA827/AD797 will sound as "analog" as can get...and far more detailed than vinyl will ever be able to(50dB crosstalk on vinyl I think?) some high quality mastered CD on a CD player running from a linear regulated PSU w/ high end opamps will sound awfully good...w/o the nasty vinyl crackles and pops at that Last edited by leeperry; 18th May 2010 at 02:41. |

this seems to be a newb question, but have all those chroma and luma up-/downsampling settings any effect when the displayed size of the video and resolution of the output screen is 1:1 ? or is this something entirely different and has nothing to do with that?

you can always use my "Bronzés" sample(the one shown in the OP) and run tests: http://www.mediafire.com/file/zirwxawggmy/Bronz%E9s.mkv Last edited by leeperry; 18th May 2010 at 02:30. |

I'm having problems with some wmv files. Found a small one that won't play:
