I'm not sure where the article got that 50 Mb/sec figure from, but it sounds a bit low. Uncompressed, it's more like 50 Mb per frame - 1.5 Gb/sec (4096x2160, 3 channels, each channel is 16 bits, up to 30 frames/sec). According to their tech specs page* there are two compression options: 18:1 and 3:1. The former gets it down to about 84 Mb/sec, but it's difficult to know what kind of a quality hit you'll be taking. With the latter it's still 500 Mb/sec. Film-makers generally want to capture source footage at the highest quality possible so I'd guess most will film at the 3:1 compression level. If that assumption holds, 2 hours of footage is approximately 3.5 Tb of data. That is still a fairly manageable amount of data though. For comparison, The Tale of Despereaux - an animated movie which came out in 2008 and started production several years before that - filled up a 192 Tb disk cluster. * http://www.red.com/products/scarlet#product-tech-specs http://www.red.com/products/scarlet#product-tech-specs Edit: I think I might have made some incorrect assumptions about the REDCODE raw format, so my figures above are probably wrong. Sorry for any confusion!
