Wipe Transition
A wipe is a transition from one picture to another in which a
shaped edge moves across the screen revealing the new picture
(see
Figure 3-2 ). A background wipe removes the old Program
Background picture as it wipes on the new Preset Background
picture. A key wipe reveals the key over the existing background
or removes it without affecting the existing background. A wipe
transition can also change the background and the key(s) at the
same time.
Wipes can take the shape of any of the available wipe patterns,
which can be adjusted for position, aspect ratio, multiples,
rotation, modulation, edge width, edge color, and edge softness.
Twenty-four wipe patterns are available from the control panel,
and additional patterns may be selected from the Wipe/Wipe
Pattern Menu.
