If DVE is used as background transition, it is possible to select whether the signal is
to be switched to the DVE from the Background or the Preset bus. This selection
permits a determination of the type of transition.
Key Preset ON: new picture comes in
Key BGD* ON: old picture goes out
* With some devices this key is designated PGM.
If the function (key) Loop is disabled, only the DVE key signal is switched to the
DVE, not the video signal. This way, a DVE effect may also be used as wipe effect
without manipulating the video signal.
In this mode 1 (FX Loop), the DVE is only switched into the signal path during the
transition.
Note: It is possible to deviate from the automatically switched video and
key signals and to switch other signals. However, this may result in
partly peculiar pictures.

Select the DVE key (DVE1 or DVE2 in case of DD20; DD30) on the Aux bus delega-
tion bank.
Disable DVE transition in the Transition panel (if enabled).
Select the picture component to be switched to the DVE (Key 1, Key 2).
Enable Loop, i.e. switch DVE into the video path.
Note: For DD20, DD30:
In exceptional operating states the keys in the ”to DVE only” field may
fail to respond. For the selection of a picture component, one of the
keys ME1, ME2 or PP must be held down.
The DVE digipot in the Wipe panel permits running the DVE effect. As it is difficult
to achieve a continuous sequence with the digipot, this operation can only be
recommended for a static DVE positioning. A uniform movement can, however, be
realized with an EXTRA timeline. The picture component manipulated with the
DVE can be faded with Wipe or Mix in the Transition panel.
Note: Function Loop ON DVE in video path for the picture component
Function Loop OFF DVE not in video path for the picture component
