Not just encoding, but it also depends on a number of things like color depth, chroma subsampling (4:2:2), and so on. It's not uncommon for a single film to approach half a petabyte of raw in a digital world with a "typical" setup (4:2:2, ProRes maybe, 10-bit, etc). To use an example, I think I read somewhere that Gone Girl shot a few hundred TB for a technically straightforward film. Some cameras, particularly when you start getting to digital cinema (which is > "4K"), can shoot as much as a terabyte and a half per hour. There are 8K sensors in common availability now; RED has one that can shoot 75fps 8K at 2.4:1, which I don't even want to calculate, but that I know for a fact it can't write to its own storage at native bitrate. Productions eat storage these days and moving that data around is a challenge.

Hint, hint, to clever founders: hard drives in Hollywood.
