Wipe Operations

The wipe usually signals the end of one scene and the beginning
of another. A wipe is a transition between two video signals that
takes the shape of a pattern. The effect is that of one picture
pushing the other off the screen.

Background Wipe

A background wipe (

Figure 4-5

) uses a pattern to transition from

one picture to another. To wipe between M/E 1 A and B bus
sources:

1.

Select Source 1 on the A bus background

crosspoint

row.

2.

Select Source 2 on the B bus background

crosspoint

row.

3.

Select the

BKGD A

Transition button. (The Preset scene will

appear on the Preview monitor.)

4.

Select the

WIPE

Transition button. This selects the wipe mode

as the next transition and delegates the wipe pattern selector
to M/E 1’s primary wipe.

5.

Select any

pattern

button in the Pattern section. (If you want to

select a menu pattern, double press the

MENU

button in the

Pattern section and select a pattern from the display menu
that appears with the soft knob.)

6.

To do a wipe transition with the selected pattern, move the

lever arm

between limits. The B bus scene will wipe on air as

the A bus scene wipes off, and the A and B bus crosspoint
selections will flip-flop (swap) at the end of each transition.
