I have the trial version of adobe premeire pro cs5. When working on a practice project the sequence window is 4:3 (720x480) aspect ration while the source window shows a full 16:9 1920x1080 pixel ratio. When I try to change it by clicking on the sequence tab on the top of the window the settings are grayed out (meaning I cant change the aspect ratio). I am wondering if this is because its a trial version or is this some other issue. Any help please.
Thank you so much
