Hello. I'm a little bit new to film processing (motion pictures). I have a small job at hand, in which I have to create a short (30 seconds), made out of graphics and text. I'll use Motion for this. I know that the most used resolution is 2K for film projection: 2048x1556. What I want to know is, what colour depth I have to use, what colour space (RGB, LAB, ...), what pixel aspect ratio, as 2048x1556 is obviously nearly 4:3 and not 1:2.39 or 1:1.85. Can anyone put me in the right direction (other fora, articles, .....) or give me some hints what else I have to consider doing this job? Thanks in advance.
