| Posted: | | | | If you vote NO, please give a reason for not wanting any expansion of details, if you vote YES, please give what is the most important for you or give additional ideas.Things are not as simple anymore, concerning "Video", as it was during the heydays (the sole existence) of DVD(-Videos)'s. DVD's were rather 'simple', they had a (then unnamed) "standard definition", coded in MPEG-2, PAL/NTSC, had a specific aspect ratio, were anamorphic or non-anamorphic. These were about the only "factors that defined the image"; the one could be suspected, the other could be defined under the “Video”-field. I think with HD media (Blu-ray Disc and HD-DVD) times are (getting totally) different, and that combined with the sheer dedication that crept in detailing the technical specification of audio tracks, the same care is justified for "Video". The lack of details for HD media concerning Video is staggering I want to outline some of the details I would like to see under "Video", because I think they are useful and will be a great help choosing the "ultimate edition" of a movie, since every aspect details the technical presentation on screen. HD media are "high definition media", but they can also be employed as "high capacity media” with SD content as main feature, which makes discerning means even more appropriate. These HD media have so many technical possibilities that details are not just “something fancy”, but as needed as the details we give to every Audio track. I would connect the needed fields to a few questions we can ask here. * SD or HD content? * What resolution, if HD (720p/i, 1080p/i, and in the future: 4K, 8K, …)? Also, has there been upscaled? * What codec has been used (MPEG-2, H.264/MPEG-4 AVC, SMPTE VC-1)? * Is the Feature Film 2D/3D ( Anaglyphic or Stereoscopic)? And can you choose the way to see the movie (by means of inclusion on the same disc, or extra disc)? *Something I’d like to see optionally: the inclusion of the OAR (Original Aspect Ratio), and the option to note whether the Feature Film solely contains color shots, monochromatic (black-and-white and tinted), colorized or mixed shots (for example: red dressed little girl in Schindler’s List). Some may have been posed as Feature Requests before, the fact that I re-iterate them underlines my opinion of evaluating and thoroughly considering them for inclusion. Note that these are just shimmering ideas, but the main lines I would like to see included are here. What would you think? Please see this as a beginning to a larger debate as what REALLY should be included under Video, and how to do it. | | | Last edited: by MatrixTom |

cya, Mithi While non-1080p titles may not be common they do exist. Have a look at 5051561000591 (Doctor Who Complete Specials). The first episode is also listed as being upscaled. |

| Posted: | | | | Codecs and resolutions can be verified easily with the disc, but things like OAR would be a nightmare when sometimes even the director and DOP can't agree on the matter (or should that be IAR, intended aspect ratio? Maybe we need one DIAR and one DOPIAR) And nowadays we also have films released in multiple formats at the same time, like IMAX. | | | First registered: February 15, 2002 | | | Last edited: by Nexus the Sixth |

The first episode is also listed as being upscaled. That is because the idiots who designed the specification for Blu-ray had their collective heads up their butts and didn't include 1080p25. So, material that is sourced 1080p25 has be be converted to 1080i25 before it can be placed onto Blu-ray. The stupid thing is that 25p is only one frame away from 23.976/24p. BTW, 720i doesn't exist. | | | Mr Video Productions If it isn't Unix, it isn't an OS :-) |

Antichrist Blu Ray 1080i. And there are many more. I really think at least this has to be in the profiler. |

Just as 1080p25 doesn't exist, 1080p29.97/30 doesn't exist either. Even if video was shot at a faster 60p and converted to 30p for Blu-ray, the format is not supported. The only 1080 progressive speeds supportsed deal with film rates (23.976 and 24). IMHO, dumb, real dumb. | | | Mr Video Productions If it isn't Unix, it isn't an OS :-) |

| Posted: | | | | I think it was a good decision not to include 25p because then we would have even more cheaply converted PAL broadcast sources with the 4% speed-up in Europe. Now if they want progressive they are forced to use 24p sources. | | | First registered: February 15, 2002 | | | Last edited: by Nexus the Sixth |

Now if they want progressive they are forced to use 24p sources. Ah, the speed-up could still be there in that the conversion would be to 1080i25. Besides, you really don't want/need PAL material bumped up to 1080i. Because HD TVs/monitors are supposed to support all of the international rates, in theory a movie should be released as 1080p24 in the UK and all HD sets would be able to display it. But, because I suspect that studios will be cheap, they'll only make a 23.976 HD Blu-ray master and use that worldwide. My objection is because of programs like Doctor Who, which I believe are produced in 25p, but forced to be placed on Blu-ray as interlaced. IMHO, 25p source material should be able to be authored at 25p. Since I can't take Doctor Who Blu-ray video and place it on my computer, I can't really tell if indeed the material is sourced at 25p. | | | Mr Video Productions If it isn't Unix, it isn't an OS :-) |

| Posted: | | | | I want this, too. I wish Blu-ray had supported basically any framerate and converted as necessary. Material shot at 25 fps or 30 has to be interlaced and 16 fps, which was a common silent speed, can't bee done correctly. | | | Last edited: by Ace_of_Sevens |

But, because I suspect that studios will be cheap, they'll only make a 23.976 HD Blu-ray master and use that worldwide. HDTV sets existed long before Blu-ray and 24p became the general norm and broadcast HDTV is still either 50 or 60 Hz interlaced, never 24p. I agree it's not ideal but companies will take cheap short cuts and use old broadcast transfers when they can get away with it. So at least now they will have to advertise it as 1080i/50 and not real progressive HD. So people will call them out and demand new transfers in 24p, hopefully. | | | First registered: February 15, 2002 |

I really think the HD resolutions are a big fu**ing white whale and should have highest priority. |
