With the Understitial format, it is recommended not to animate several slides/scenes in Creative, since only a maximum 250px high section is always visible and otherwise only fractions of the advertising message reach the user.
ATTENTION: Please mark the advertising material on the left or right bottom edge with a clearly visible -w-. Please do not use the top right corner, because there is an adserver info button.
