ONCEPTS
Transitions create on-screen effects used when switching from one source to another
(that is, one scene to another). The most basic type of transition is the
cut , where the
first frame from the NEXT source immediately replaces the last frame from the CUR-
RENT source. Cuts produce abrupt changes. Other types of transitions use special
effects to produce a smoother, more artistic change from one source to the next. The
following illustration shows a horizontal wipe transition.
Note
When discussing transitions, we use the letters a and b to differentiate the beginning
scene ( a ) from the ending scene ( b ). These letters often appear in the transition icons to
indicate the direction in which the transition travels. These letter indicators have no
relationship to the A, B, C, and D letters used to differentiate between MXPro
channels.
The following basic steps explain how to run a transition with MXPro. Each step is
described in more detail later in this chapter.
Procedure
To run a transition:
1 Display the CURRENT source on the output screen. For example, press CUT/A to
make A the current source.
2 Select the NEXT source — the one you want to appear on the output following
the transition. For example, press
NEXT/B to make that the next source.
3 Select a transition to use. For example, press the BASIC Transition Category but-
ton, then select a wipe transition from the menu.
4 Prepare the sources (such as VCR’s and camcorders) and let them roll.
5
At the right moment, use either the T-BAR or the PLAY button to run the
transition.
