Wipe Operations
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.
