Hey Guys, I got a question for your collective wisdom, actually its two  1.) I went to see Transformers in 3D yesterday. Good flick, some of the special effects in 3D were pretty good and "real" but here's my question. It appeared to me that although the effects were "well done", some fidelity was lost in the process. In particular in cross screen motion (e.g. the explosion effects or pan/scan effects). I viewed this at a local theater with Christie 4K projectors so I know they are good. So: Is there fidelity loss in 3D even at the theater? I must say had it not been for these artifacts, I probably would have been wowed instead of left wanting more. Keep in mind that this is only the second 3D flick I have seen at the Theater, I usually just stay home and watch on my HT. 2.) Much shorter lead in I promise. I have a fully calibrated system using RTA at home, but why does reference volume seem so much damn louder in my HT than the typical theater I go to. With a few notable exceptions over the past few years (e.g. Dark Night, Revenge of the Fallen and a couple of others) I would swear the theater is not turning their volume to reference. . .or mine is not properly calibrated. . .which it is I swear! Thanks in advance for your informed replies!!! Chris ;D ;D ;D |

1) There are always artifacts in any digital process no matter how high quality it might be. Sometimes you can see them sometimes you can't.
2) What makes you think the cinema you attended has calibrated their system to reference, that they use that as their playback level, or that it is the same in every seat? Most do not.

Don`t quot me on this but I think it has to do with the 24fp ,3D blu-ray will be much more detailed and less artifacts in the panning

Most do not. Thanks for the reply! These were pretty visible tracer effects for explosions that almost reminded me of old school LCD monitors and fast moving sequences. Other than that it was pretty good. And to your second answer: Why wouldn't they use reference volume? Isn't that the volume at which filmmakers recorded the sound and intended it to be heard? |

It just seemed to me a bit amateurish when the explosions had visible trailing artifacts. I don't have a 3D set and so far my experience at the Theaters tends to make me not want to upgrade. Although I am ready with my Oppo. Overall It just seemed like the video quality wasn't as good in 3D as 2D. Just MHO |

And to your second answer: Why wouldn't they use reference volume? Isn't that the volume at which filmmakers recorded the sound and intended it to be heard? No, not at all. "Reference" volume is simply a calibration standard at which systems are set up so they can properly reproduce a soundtrack. If they can attain reference volume without distortion then they can reproduce whatever it is that is in the soundtrack. But the actual playback volume in your home or in a cinema is whatever you or the exhibitor want it to be. "Reference" (and actually there are several different versions of reference depending on which system you use to set things up) is simply a standard level used literally as a point of reference. |

Cool! Thanks. . .thats what you gotta love about this forum, you learn something new every day! Now it makes me wonder how they (or I should) decide to playback volume. I rarely jack mine up to reference as it is too loud with a little guy sleeping at night (when I watch most of my movies). Thanks again for the great info! Oh and did the dust storm create hell for you in the clean up department? |

Oh and did the dust storm create hell for you in the clean up department? My advice on playback level is, after you have your system all set up, turn the volume knob to whatever makes you happy.  The giant dust storm left a thin layer of brown dirt on everything but other than a visit to the car wash and some time sweeping the porches, no real after-effects for me. People with pools were hating life as they had to have them cleaned and in some cases drained and cleaned. |

It is possible they didn`t have the projector setup right many theaters seldom do

1) 3D filmed with 3D dual lenses cameras is relatively brand new. And there is much more to be done for la-creme-de-la-creme. - Peter Jackson is filming "The Hobbit" with new digital 3D cameras and at a true digital 48fps. - James Cameron is working also on better digital 3D cameras, and should have something for us by 2014. It's a brand new world, and we're just starting! And eventually 4K, 8K, 10K, 16K... >>> And a big point here; you need 144fps or 192fps multiple frame rate for artifact's elimination! 2) Sound in commercial Theaters is all over the place! Some with exaggerated bass and loud unbalanced sound! _________________ *** And don't ever forget this: A camera doesn't see like a human eye! Focus, motion, etc., are done, viewed differently. |

I personally am looking forward not so much to 3D in the home but 4k sets in the home. It would be killer to rock a 120+ inch screen that had killer detail. Till then I am happy with my 65" |
