AE & Premiere Pro are two different animals (I have licenses for both @ CS3 level)... AE is more like photoshop with motion, layers - compositing - where PPro is closer to FinalCUT or any application were you are more concerned about transitions and timeline editing, mixing with music, etc.
AE composites can become very sophisticated, with nested compositions, tracking, stabilization and advanced color correction, grading and conforming to mix a few terms.
BTW - I may be confusing perceived gamma issues with neutral picture style experiments. Funny thing is I uploaded a 'hot' test file to the tube and it normalized after processing. Strange.
I'm starting to gather questions and techniques, although I don't think I will be twisting the lens :lmao:
Go to sleep man, tomorrow is another day. -S
