So another thread has brought up many topics that got me thinking about the eventual release of the Star Wars films on 4k Blu Ray. Now, for the six films shot on 35mm, this will be straight foward. They can simply pull from the 35mm for the highest possible resolution, just like every other 35mm film released on 4k so far. However, AOTC and ROTS were not shot on 35mm or on film at all. We all know they were shot on HD digital cameras in 1080p. The analog "resolution" of 35mm allows for some pretty amazing clarity even at 4k resolution when properly transferred and restored. However digital resolution is a hard limit. There is ONLY 1080 lines of horizontal resolution stored from AOTC and ROTS. Period. That's Blu Ray quality, for those who wonder. The new "4K" format is 2160p, or double the resolution of HD. Seeing as data cannot be created out of nothing, what will they do to release AOTC and ROTS on 4k Blu Ray? Is there some spectacular new way to line-double and have it look right? Will they simply be presented in HD 1080p instead of 4k? These are the first major films ever shot in HD digital, so this seems like new territory.
