Author Topic: "Dunkirk" - BD has been panned and scanned! Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 01-10-2019 07:36 AM                     We are in an age where most disc releases have multiple copies inside...why not release it the IMAX form and the 5/70 form and be done with it. Those that want the full composition...have at it and those that one a steady state 2.2 have at it? As for aspect ratio changes during a movie that work: "Brainstorm." Too bad the brainstorm sequences weren't ShowScan too.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

Could this be done with a menu selection? I don't know much about Blu-Ray authoring, but maybe someone else here does. Or is there such a thing as a double-sided Blu-Ray? I have some DVDs like that, with the 4x3 version on one side and the wide screen version of the same movie on the other side. A two-disk version is fine, too, but I suspect that it would just give the manufacturer a reason to justify a price increase. The changing-aspect-ratios thing would be annoying enough on a television set, but would be truly maddening for anyone who went to the trouble of installing a projection system and masking at home.  |  IP: Logged Scott Jentsch Phenomenal Film Handler Posts: 1061 From: New Berlin, WI, USA Registered: Apr 2003 posted 01-10-2019 10:14 AM                        Blu-rays have the ability to feature seamless branching, which allows for different scenes to be played, based on a setting that can be chosen in advance. It hasn't been used in a lot of titles, but it is a feature that could be used exactly how you mention. I'm not sure if 4K Ultra HD Blu-rays have that feature. My guess is that it would be much simpler to provide another disc, but the most likely scenario is that the status quo will be maintained. The lazy attitude of catering to the lowest common denominator is very prevalent, so streaming services are going to show things in full screen on the device on which it is playing and/or what is easiest/cheapest to provide. I hate forced IMAX aspect ratio changes, because I have a constant image height setup. If it's part of the movie, like Cape Fear or The Horse Whisperer or The Right Stuff, that's not a problem, but so many are the "ooo, let's go to full screen so that someone can see more image filling his 65" flat screen in his living room, connected to that $100 sound bar he bought at Bed Bath and Beyond." One day, when I'm able to upgrade my projector, I'll be able to have it mask off those changes and be done with them.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 01-11-2019 01:00 PM                        It is theoretically possible to make a double-sided BD, though I've never seen any. I do have a few DVD/BD combos (DVD on one side, BD on the other). The issue is the data capacity. There is a hard limit of 50GB for a regular BD (dual layer), or 100 for a UHD (2160p) BD. You're not going to get two copies of a two-hour movie onto a single disc, therefore, unless you use a pretty low bitrate. As the cost of disc pressing is negligible for a mass-production release, I see no reason not to use multiple discs. This is what umpteen "special edition" versions do, anyway. As I mentioned above, I do have some examples of different technical versions on a multiple disc set, Oklahoma! (Todd-AO 2.20 and CinemaScope 2.55) and The Big Trail (70mm Fox Grandeur 2.0:1 and 35mm Movietone 1.19:1), so there is a precedent for going this route.  |  IP: Logged
