Is 4K a game changer?

The most popular type of digital camera in the professional arena (give or take) is the ARRI Alexa. It has a chip whose resolution is between 2 and 3.4K, depending on how you like to count it. Recently they introduced a mode where you could get a 4K picture out of the camera, using an internal upscaler.

Netflix (rightly so) saw this as a massive cheat, so have banned people from using that on their shows where 4K is a requirement.

Bayer Patterning is too complex to try and explain in a post here, but long story short your TV has a red,green and a blue sub-pixel for every pixel on the screen (if you've never seen them, just walk up very close to it - easier in the SDTV days!). Cameras can only have each pixel red OR blue OR green - so there's a fair bit of guesswork involved in creating colour and resolution suffers. Hence cameras with three chips (one each of red,green,blue).

I'm happy to answer any questions on the camera side of things, but opening a new topic might be wise
