While shooting video the only way to change exposure compensation in for ex. AV mode is to hold the exp. button near the 4 way buttons and scroll the front wheel.
If it is possible the compensation should be able just with scrolling the wheel without holding the second button (this adds shake to recording). Now on itself it does nothing so it's "free".
