Hi madshi, couple of things for you.
1) The option to treat 25p videos as 24p works fine, trouble is it also treats 25i videos as 24p. This is a bit annoying because 25i material is usually TV material and therefore does need to be slowed down. 2) Do your decoders are assisted by the gpu? I use LAV Cuvid specifically for that reason. I'd rather not ask my CPU to decode video frames when my gpu can do it better. 3) For some stupid reason neither my TV nor my graphic card remember when I set them to "no overscan". If I want no overscan I have to set it manually everytime I switch my TV input to HDMI, so I just gave up (overscan isn't so bad anyway). Problem is overscan means the exclusive mode seek bar is barely visible (just the top of it, not even the bar itself), and the OSD is partially hidden. Any chance you could add the option to move up the seek bar and increase the margin between the border of the frame and the OSD? The weird thing is even for 2:35 videos the seek bar is at the bottom of the screen, instead of the bottom of the frame... Personally i'd rather have it the other way. |

I'd suggest trying different MPC-HC builds, because the problem only seems to occur with MPC-HC. |

I also reported a problem with Zoom feature of Zoom Player and madVR exclusive mode in 0.66. The crash was fixed in 0.67 but madVR quits exclusive mode as soon as I try to zoom with "exclusive mode failed" OSD message. |

(1) Someone who is working in a mastering house (Mr.D)? (2) Someone involved with ISF and consumer electronics (Joe Kane)? Both are knowledgable persons, IMHO, but I think in this specific case Mr.D knows better. Real world experiments? I'm not really the color guy. I can see differences in sharpness, detail, grain etc very quickly. I can usually tell you whether a master is an old 2K master or a new 2K master or a 4K master, just by looking at it. But ask me which colors are correct? I don't know. IMHO the differences between BT.601 and BT.709 primaries are not *that* big. But everyone is different. I care much about detail and lack of edge enhancement. I don't care as much about color. I still want madVR to be as accurate as possible, though, of course. madVR auto switches to EBU primaries for content with a height of 576 pixels and to SMPTE C for all other SD content. That should cover most DVDs. Anyway, I already said that profiles and rules are on my to do list. But we can continue to discuss this for days, it won't change the priority of profiles and rules in my to do list. Last edited by madshi; 24th July 2011 at 20:12. |

Well yeah that's kinda what I meant. I'm using a laptop, not really a week laptop but I try to save as much calculating power as possible. Not that I wanna play Crysis 2 while watching a video at the same time but I'd rather my movie not lag whenever I'm being contacted on MSN. Which is why I prefer hardware assisted decoders. |

The only pattern that I've found for this problem seems to be the application that has been used for coding the movie. I mean, every file that freezes the player has been coded with mkvmerge v4.4.0 or higer. Also, another movie that gives the freeze error has been codec with virtualdubmod. All the other movies have been codec with versions of mkvmerge lower than 4.4.0, and all of them play perfectly fine. Does this make any sense to you? |

There are many naysayers on audiophile forums that like to call bs on anything they haven't tried, just for fun...all I've read so far about this gamut matter here on doom9 is ppl who haven't done any real world experiments. Someone said "talking about music is like dancing about architecture"...that's the exact same story as w/ this gamut mumbo jumbo, depending on who you ask you'll be told that most/some mastering houses do their job properly, and that some/most others don't. How about trying it for yourself, and see what your brain has to say about it? Quote:
Either way, I'm glad to hear that some automatic gamut mapping rules will be in the works at some point, as that will make a lot of colorimetry freaks happy fosho! How about upscaled EU DVD then? Last edited by leeperry; 24th July 2011 at 21:47. |

The problem with these "real-world experiments" that you seem to value above all is that you don't have the actual source to compare to. The only way this could work is if you bring your system to the mastering house, then play the BD side-by-side with the mastering monitors. Then the comparison would be valid. But of course this isn't gonna happen.
Right now all you're doing is switching gamuts on some BDs and declaring "oh, that's much better". Which is purely subjective. And no, you can't say "oh, that's much closer to the source", because you don't have the source to compare it with, so you honestly can't make that statement. One thing I learned when calibrating audio equipment (I'm developing audio calibration software) is that you can't trust people's judgments when it comes to fidelity. Including my own. Remember that the goal here is fidelity. I'm perfectly fine seeing purple lemons on my screen as long as I'm sure that they were purple on the screen of the mastering engineer.

Good news, tried the problematic video and reloaded it 50 times with resume last position and no crash on load. Bad news, switching MadVR between fullscreen on monitor #1 and windowed mode on monitor #2 causes several issues: The video will freeze with audio playing requiring a pause+play (graph stop+play) for the image to continue playing. On the second attempt, the video blacks out, requiring a pause+play for the audio to play and several seconds for the video to return, but when the video does return, the entire player interface becomes unresponsive, forcing a task kill. This happens even with fullscreen exclusive mode disabled... I can't create a debug log, as the latest test version didn't include a debug build. |

Fact is, the experts do *not* agree on this one. And subjective impressions of what might look more correct to your eyes are just that: subjective impressions. I'm not saying you're wrong. But I'm also not saying you're right. I consider this matter undecided. Maybe some Blu-Rays are encoded to SMPTE C primaries, maybe some are encoded to BT.709 primaries, maybe some are encoded to EBU primaries. Maybe things will change fluidly, as new mastering monitors are bought (studio CRTs are out of production). I believe the best solution for madVR is to stick to the standards. Already works, too, if you upscale in realtime somewhere in the DirectShow processing chain. madVR will detect the dimensions of the original video before upscaling and use that for primaries auto switching. Give it a try! Quote:

Many audio equipment manufacters will throw amazing SNR/THD/IMD specs at you, but that doesn't prove anything whatsoever. It can measure like crazy and sound like crap...the subjective judgment and the end-user satisfaction are what truly matter here, and the only way to find out who's right or wrong on a case to case basis is to run real world experiments. There's a good chance that you'll be seeing the light, or maybe not...but at least you will have tried. Your real world experience will give weight to your opinion. Quote:
But a proper 0-255 YV12 pipeline would be great, for when I don't have enough CPU horse power to run ddcc(). |

There's another problem with real world experience: Not all Blu-Rays are equal. Actually far from it. Just look at how FOTR suddenly got a teal tint. The difference between the TE and EE editions of FOTR alone are much *much* bigger than the difference between SMPTE C and BT.709. And many newly remastered movies (e.g. Aliens) seem to have that teal tint. Also many movies were intentionally regraded to look unnatural. Probably that applies more to fantasy, science fiction, action etc movies, and less to dramas. But well, the former is the movie type I prefer. Anyway, what I'm trying to say is that I doubt that subjective impressions can have any say in which is the "right" gamut. Furthermore: Our eyes/brain adjust very quickly to different white points (that's why FOTR EE doesn't look nearly as tinted during actual movie watching compared to looking at screenshots). That's another big problem in subjective impressions...

1) Is it possible to change the OSD shortcut from Ctrl+J to some other combination? 2) Using KMPlayer, madVR's seekbar never shows. If you move the cursor at the bottom, it shows the KMPlayer's seekbar, so switching to windowed mode. |
