Mix and Wipe Transition Type
The [MIX] and [WIPE] buttons determine the appearance of the next
effects automatic or lever arm transition—either a dissolve or a
pattern transition. Only one button may be selected at a time.
Mix
The [MIX] button selects a dissolve transition. Keys dissolve on or
off, and/or Preset video dissolves into and replaces Program
video.
Wipe
The [WIPE] button selects wipe transition mode and delegates the
Pattern and Matte sections to wipe adjustments. In wipe transition
mode, a moving pattern edge wipes keys on or off and/or
replaces Program bus video with Preset bus video.
■ The Pattern controls allow you to select a wipe pattern and
position its starting point. They also allow you to turn the
wipe border on or off, adjust edge or border softness, and
adjust edge or border softness symmetry.
■ The Matte controls allow adjustment of the wipe border
characteristics, including luminance, saturation, hue, and
opacity.
■ A double press of the [WIPE] Transition button brings up the
Wipe menu, giving you access to more pattern adjustments,
including more patterns, aspect, reverse, rotation, and
multiplication.
