When you reduce the resolution to one quarter of the original, information is lost (4:2:0 is one quarter chroma resolution). You need a proper reconstruction of that data, and nearest neighbor resize will just produce 4 pixels of the same color, which is not how the original looked like (probably not even close)

Ok. Can you please check this build to confirm that the problem is gone for you:

Good to hear. To be honest, I don't really understand why the "fix" I implemented now changes anything. It's basically the same as v0.80, just some code sections re-ordered. Makes no sense to me. But well, as long as it works...

About A.I. from a quick test I just did I can't see a difference.So madshi is probably right. In the past I thought it caused slight shimmering but it was placebo probably. |

Tried, but failed. The MSVC++ base classes have some linker magic which require the mediatypes to have a specific name. So basically I can only use one exact list of mediatypes. At least I don't see how I could do this differently in any easy way. And I don't think this is important enough to warrant hours of searching. |

The new build posted averages 22/53. As I said, the dropped frames only seem to be initial numbers within the first few seconds of playback, but it seemed strange, so I thought I should mention it. (presentation glitches keep increasing with the default flush settings) Whatever that small difference is, must be doing something. Using the "framequeue" build which showed the least number of dropped frames & presentation glitches, and changing the flushing to don't/don't/don't/sleep, I was able to watch a 40 minute 30p@60Hz video without any framedrops/presentation glitches past the first minute, where it climbed to 7/43 and then stayed there to the end. I need to do extended testing with this using some longer videos (sometimes problems only show up after an hour or so) and with the "maybe fixed" build, but it may be a solution for people that need to run the latest Nvidia drivers. (0.80 seemed fine with these flush settings until I tried longer videos though) Last edited by 6233638; 14th February 2012 at 20:00. |

EDIT: Enabling the "delay playback start until render queue is full" option eliminates these dropped frames at the start as you would expect—the reason I mentioned them is that clearly something was happening to increase them 3x. More importantly though, this option no longer seems to break DVD playback (off the disc) though presentation glitches still increase for the first minute or so of playback before stopping. Quote:
From that brief test, it did stay at 0 dropped frames and 0 presentation glitches, but I'm wary of leaving the queues so low. I suspect that there will be dropped frames/glitches appearing when watching a long video in that state. I believe you are using a different generation of card though, which is probably why that is the case. (I never had any problems with the new rendering path with my old 9400M based system) Last edited by 6233638; 14th February 2012 at 20:04. |

Hi madshi,
In one earlier post you promised to post details how to drag a freeze report, because I did report you a MPC-HC freeze using madVR refresh rate changer ( happens not always ) - going from native 60Hz to 23Hz ( 1080p23 setting ) on my VT30 plasma. It happens in both windowed and exclusive mode. I would like to prepare such log for you. Or have you tried to reproduce this in between? Thanks Pluto

I have best PQ (my opinion, not scientific) when I set "tv is already calibrated" (set there your specs) and then check gamma prosessing and set there what seems to be the best settings... I have these BT.709 and BT.709/601 curve 2.10. Gamma prosessing is pure power curve 2.10... Black level seems fine and I have much better contrast, so I think it is correct settings... |

Film gamma is 2.40.
Depending on your TV, it's probably not even 2.20 to begin with (or 2.2 if it's got a good film preset/THX mode) so you are further reducing the image contrast by using madVR to lower the gamma. |

I know that. Will try to be fair against the filmmakers as soon I will get my hands on a new TV set, which should be brighter and I wont need any further gamma or brightness adjustments if properly calibrated ( looking at Panna WT50 or VT50 currently ).
