Author Topic: Complaining Cinema Owners... Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 07-29-2011 09:20 PM                     Much of the stuff from Sony is released on 4K. Warners and Paramout also release it from time to time. True Grit was the last big one that comes to mind and was Dream Works. As 3-D fades out somewhat 4K 2-D will become more common as there are quite a few of these projectors going in.

If going to 4K is an increment of cost that is justified by those other aspects, why not? And who knows, maybe the studios will catch on to 4K when they get tired of tooting the 3D horn...  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-01-2011 09:54 PM                     At least with NEC once you are at the NC3200 to go to the 4K 3240 is about 7 grand more give or take. So it would seem foolish for anyone buying an NC3200 not to spend the extra cash for the one that has more future possibility.

Same compression. For a really detailed image, the 2K image could very possibly be of better quality. I suspect any perceived improvement in image quality is a result of improved projector technologies as much as the resolution itself.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 08-02-2011 09:19 PM                     J2k excels at higher signal frequencies, so, 4k at the same bitrate as 2k is not as bad as it may sound. Given the fact that most movies to date do not nearly max out the DCI spec, I wouldn't care about the current limits too much. To me it seems J2k was an excellent choice. You could complain about all possible aspects of DCI projection, but visible codec artifacts? - Carsten  |  IP: Logged Brian Guckian Jedi Master Film Handler Posts: 594 From: Dublin, Ireland Registered: Apr 2003 posted 08-03-2011 10:26 AM                     quote: Mark Gulbrandsen At least with NEC once you are at the NC3200 to go to the 4K 3240 is about 7 grand more give or take.

Just wondering, Mark - what would the additional lens cost be, if one accepts that a lens with a better MTF is a good idea? What is the price differential between say, the two Barco lens ranges that Carsten mentioned earlier, or say, higher-contrast lenses compatible with NEC projectors?  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-03-2011 12:23 PM                     Personally, I didn't have too much to complain about with the standard lensing. The image is fantastic with it. Probably as good as one would get from a Zoom lens with more than a dozen elements in it. As to the difference in lens pricing, I honestly don't know, you'd have to call them or your local dealer and ask. I also don't know if the actual lens used in the studio series has a higher MTF then a standard one does but by simply adding an aperature in the lens it can have that effect as well as increase the apparent contrast range. Personally, I am hoping that Schneider comes out with some lensing for the 4K format and they would probably be primes. The nice thing about the NC-3200 and 3240 is the lens mount that is attached to the lens makes switching lenses very easy. Schneider have a few D-Cinema lenses now but not very many.

Good point re. apertures; although now that I think of it I seem to recall a point made before that the gap between the DMD micromirrors is larger with 4K DLP so perhaps one needs to be careful not to bring about a re-emergence of e.g. the screen door problem through being over-zealous with resolution and contrast.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-03-2011 04:21 PM                     The gap actually has to be much smaller as the chip is only .18" larger diagonally than the 1.2" chips are.  |  IP: Logged Brian Guckian Jedi Master Film Handler Posts: 594 From: Dublin, Ireland Registered: Apr 2003 posted 08-04-2011 07:08 AM                     Many thanks indeed Mark, I'll go back and see how I got that wrong.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-04-2011 02:19 PM                     @ Louis.... No, there have been at least a half dozen per year since Sony released their first 4K projector. A few other studios also release 4K DCP on their big titles. In addition some 70mm classics have been scanned at 8K resolution and are also available to show in 4K. 4K has kinda been put on the back burner because of 3-Dee but now that that is loosing strength and people like Jimmy Cameron are pushing higher quality we will probably see more 4K content per year in the comming years. Of course "back in the filum days" we didn't see but an occasional 70mm title either... and just on big shows. In these digital days 4K would equate to there being a 70nmm release. Best part is you don't have to switch the gate,trap and lens to do it! Give 4K projection a chance... it's only been available in quantity since right after Cinema Con! Mark  |  IP: Logged
