Hi, I will be shooting a spot in a few weeks. The client says it will have a long shelf life and would like to finish in 4K (preparing for new Ultra HD standard--some of their spots have a 10+ year shelf life). It is all night exteriors and lots of storybook pretty pictures---(think Werther's Originals holiday spots). As of now, my plan is to shoot Alexa with a Gemmini to allow me to shoot 2.8K ArriRaw (much less expensive than shooting XT). This would obviously require somewhat of a blow-up to 4K. There is no overcranking. I'm attracted to the Alexa over Red, for example, because of the look, color rendering, etc. My questions are:
1) Do you think we can get away with this blow up?
2) I have Ultra Primes on the job now. Is it worth trying to move up to Master Primes? If I did, how would you characterize the difference we would notice? Sharper? Better performance toward lower f-stops? Worth almost double the cost on lenses? Any other lenses you would recommend for best performance out the Alexa?
3) Not shooting anamorphic, is there any advantage to the 4x3 sensor in the XT?
I am kind of basing the resolution aspect of my camera selection off of the experience of watching many Alexa movies projected at 2K in my local theatres. When they use good glass and are well-shot, I never find myself looking for more sharpness. I'm wondering if I could get away with this blow up from 2.8 K to 4k?
Any other suggestions give the description of this particular job?
I apprecaite your help.
