What will the aspect ratio be of the new digital IMAX experience? Their 15/70mm screens are 1.44:1. The HDTV digital ratio is 1.78:1 and I believe the digital cinema ratio is closer to 1.85:1. These are the pixel figures I came up with from searching the internet for information:
HD TV (Based on 60p or 30i frames per second) 2K, 1920 x 1080 = 1.78:1 4K, 3840 x 2160 = 1.78:1 (Doesn't exist yet for broadcast TV.)
Digital Cinema (Based on 24 frames per second - 48p? 72? 144p?) 2K, 2040 x 1080 = 1.89:1 (Close to 1.85:1 35mm Cinema Standard) 4K, 4080 x 2160 = 1.89:1 (Close to 1.85:1 35mm Cinema Standard)
Another Digital Cinema Figure I came across: 2k, 1996 x 1080 = 1.85:1
The IMAX screens to be placed in existing multiplex theatres are supposed to be 25% larger. The AMC theatres already have 1.85:1 wall to wall screens--will IMAX Digital screens increase the height of the screens by 25% to achieve that 1.44:1 IMAX standard picture?
Are there DLP chips with a 1.44:1 ratio, or how is this ratio dilemma be solved? Current IMAX DMR 15/70mm releases of Hollywood films often or always letterbox the image to achieve the cinema standard? Grant.
“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”
