Can anyone explain the use of such high resolutions? I know it could be nice to crop some parts of the movie and still have a nice set of pixels. But in reality you will just shoot the scene again or leave it out. Nowadays everybody is shooting millions of pixels but I never saw someone who used a cropped versions professionally.

Better aliasing performance (things like chain link fences won't look jagged), more sharpness retained after multiple rounds of processing, etc. Try recording a TV show in SD resolution, then record the HD version and resize it to SD. The HD-scaled-to-SD version is much sharper than the SD version.

  Ofcourse the SD TV show will look less sharp then the HD version scaled to SD. But this doesn't have anything to do with my question. Last time I checked HD is around 2Mpx. Why would you need 14Mpx as source material? 7 times oversampling?

    Yes, yes, a thousand times yes.

Ah, I'm totally wrong. 5K (14Mpx) is todays cinema format. http://en.wikipedia.org/wiki/Digital_cinema http://en.wikipedia.org/wiki/Digital_cinema "The marketshare of 2K projection in digital cinemas is over 98%."
