8.4 DVE CONTROL
Operating modes DVE devices that are linked to the DD switchers in terms of signals and control can
be used in various modes.
1. FX Loop
In this mode, the video and key signals to the DVE device are switched automat-
ically and the sequences of the DVE device are controlled with the fader in the
Transition panel. The DVE device permits transitions of the background and of
keyers that are controlled in the same way as wipe transitions.
In this mode, Loop and DVE transition are enabled.
2. FX Loop without fader
In this mode, the video and key signals to the DVE device are switched manu-
ally. The control of the sequences is made with the DVE digipot in the Wipe
panel, which in this mode is switched over to DVE operation.
This mode permits integrating particularly static DVE effects into a picture, e.g.
smaller pictures at a fixed position.
In this mode, Loop is enabled and DVE transition is disabled.
3. DVE effects without FX Loop
In this mode, all signals applied to the switcher as well as the internal signals
from the key levels may be selected as DVE input signals. The DVE sequence
control is made with the DVE digipot in the Wipe panel, which in this mode is
switched over to DVE operation. The DVE effect is faded-in at any key level of
the switcher.
In this mode, Loop and DVE transition are disabled.
4. In modes 2 and 3, the DVE device may also be directly controlled by an external
editor instead of the digipot. For this no control link exists between switcher and
DVE.
