In answer of your second question, you can resize the Production frame manually, it's just that you got to be precise when you select the dots in the corners . You can also grab it from its center, but you'll end with some distorted image . No, not a bug, just something we can't do with real world cameras, that's why it looks weird at first . Anyway, changing the production frame size affects the focal angle of the lens, so do it only when you're sure ! Hum, by the way, how do you resize it numerically ... :?
