Author Topic: Can 4k Play on 2k? Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 07-19-2013 06:53 PM                        There have been several trailers that only have 4K versions. We haven't had any problem playing them. (GDC server/NEC projector)  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

It is with the silly IMBs that have taken the industry by storm that the possibility of dealing with 2K and 4K has cropped up if the tech didn't set things up properly. Note too, some of the IMB systems didn't have the "force 2K" feature on them in early software versions too.  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

Are Mipmaps not involved?  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 07-20-2013 06:48 AM                     I think MipMap is a 'concept', but does not define a precise method how to store and process the data. Wavelets may be 'one' possible option. Also, MipMaps seem to be used only for texturing. A lot of textures can be compressed more efficiently with e.g. RLL than with wavelets, and still have the MipMap scheme applied. - Carsten  |  IP: Logged Scott Jentsch Phenomenal Film Handler Posts: 1061 From: New Berlin, WI, USA Registered: Apr 2003 posted 07-24-2013 12:14 PM                        Thanks for the info -- I'm impressed with the level of foresight in handling the 2K/4K support!  |  IP: Logged Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 07-28-2013 08:42 PM                        quote: Justin Hamaker Jack, many, but not all of Sony's features are 4K. This is the End, After Earth and Grown Ups 2 were all 4K Thanks for that, Justin. After talking to Deluxe about this, I recall that the DCPs for these movies only had CCAP and OCAP versions... nothing about resolution. Based on that, I happily ingested them and gave them no more thought. In the case of Smurfs 2, my keys specifically state 4K, which is what got me going (again) today. Deluxe says all will be fine. Apparently, it has been and I didn't realize it.  |  IP: Logged
