I'm trying to make a perfect circle but can't. I hold down the right key [shift] but that only make the shape an irregular shape ratio. The same thing happens with making squares or any other shape. They don't turn out right. It's like there's a "keep ratio" key turned off or something. Can anybody out there help me out?
Are you working in a composition with non-square pixels? Do you have Toggle Pixel Aspect Ratio Correction turned on?
You are working in a non square pixel comp. Simple as that. Unless you specifically have a need to go back to a non square delivery method, and none of the current formats for delivery are, you should be working with square pixel composition presets. Your end result will be better in the long run.
