RED 4K-RAW cameras have 4096 horizontal pixels. Since RAW is a Bayer pattern, the actual measured resolution is less. You can use 80% to figure out exactly what the final measured resolution will be. For example, 4K-RAW will end up as roughly 3.2K (4096 x 80% = 3276) measured resolution. 5K RAW (EPIC) will actually measure 4K (5120 x 80% = 4096).
We believe that 4K delivery (4096 x 2160) is the future of cinema, both in theaters and in the home. 4K is roughly 430% more resolution than 1080P. We also believe that it is not a good idea to acquire in 1080P or 2K for a 4K delivery.
A 4K film scan has measured resolution of about 2.8K for fast film (ISO 500) and about 3.2K for slow film (ISO 100). We do believe that 3K of measured resolution will scale to a 4K delivery with no problems. 3K of measured resolution is 256% greater than 1080P (3072 x 1728 = 5308416 vs. 1920 x 1080 = 2073600)
We don’t believe that we are alone in this thinking. Sony, Christie, Barco, Meridian, JVC and Epson have 4K projectors (the newest Sony T Model is incredible). Panasonic has just introduced their 152″ 4K plasma. Samsung, Sony and Sharp have all shown 4K displays. Now all they need is RED 4K (RED Ray) to deliver the content.
