The Norm/Rev button determines the wipe pattern direction. If this key is enabled,
the wipe pattern direction is changed every time the fader is in final position or when
the transition is completed.
If you wish to change the preset wipe direction, press Rev button.
Press Pos in the Wipe panel to enable the trackball. You can now use the trackball
to position the center of the selected wipe pattern within the visible picture area.
Note: Please note that some wipe patterns (e.g. matrix wipe patterns) can-
not be positioned.
If you enable the trackball by pressing Extend Pos in the Wipe panel, you can posi-
tion the center of the selected wipe pattern at any place, even outside the visible
picture area.
Note: Please note that in this mode, the wipe transition may reach its limit
before the wipe pattern fully covers the screen.
Using the modifiers like Mod, Multi, Wipe Comb, Wipe Rot, Bord, Soft and
Aspect the standard wipe patterns can be changed and new patterns can be crea-
ted. For more details see section Menu Operation.
The Modif reset key can be used to turn off all enabled modifiers at once.
If the wipe generator is used for a function other than background transition, the
size of the wipe pattern may be adjusted with the SIZE control in the keyers panel.
The modifiers are switched on and off by actuation of the softkeys in the respective
menu only!
When the user changes over between the individual modifiers, the selected values
are automatically stored and will be available when the modifier is selected again.
Mod The Mod key serves to enable the wipe edge modulation.
The following adjustments are possible:
AMPL modulation amplitude

In addition to these adjustments, the wipe edge modulation may also
be influenced with the following keys:
H Mod key horizontal wipe edge modulation only
V Mod key vertical wipe edge modulation only

run through but produces a stationary picture.
