Grass Valley DD35 Family v.3.1.5 - Manual (Page 66)

2. Panel Operation DD35 Production Switcher
2 – 32 Operating Instructions – Rev. 16 / 10.2001
D
In the M/E menu, use the softkey DVE Trans to select the desired DVE. This
setting remains until changed.
This setting is necessary. Otherwise the switcher does not know which DVE to
use. It is possible to select the same DVE for DVE Trans in more than one M/E.
But only one DVE transition can be performed at a time.
D
Optionally configure what is the default when using the DVE transition in back-
ground.
Use the softkey BGD DVE to define whether the DVE flies the PGM out or the
PST in.
D
In the Transition Panel, select the Transition Type button DVE. This will se-
lect DVE transition for the component that is currently activated for Next Tran-
sition. This will be indicated in the transition type displays (DVE). For a back-
ground transition, it will also be indicated whether the transition is done with the
PGM or the PST.
DVE Transition for PGM: ––– DVE
DVE Transition for PST: DVE –––
D
The indicator Loop will light up for this component.
D
The switcher has automatically changed the FXLoop setting in the M/E menu
to use the same device for the FXLoop
t
as for the DVE transition.
D
Optionally change DVE Transition.
E.g. to change the DVE transition from PGM to PST: Press and hold DVE, press
BGD-B, release both buttons.
To change the DVE transition from PST to PGM: Press and hold DVE, press
BGD-A, release both buttons.
D
Perform the transition using the Fader or the AUTO transition.
During the transition, the switcher automatically routes the signals to and from the
DVE (makes the FXLoop
t
). When the transition is finished, the loop is automati-
cally switched off and the switcher uses the direct input.
To use a DVE effect for DVE transition it must be programmed in a special way, so
that a complete transition is the result.
D
The first keyframe must be a complete, untransformed image.
D
On the last keyframe, the image must be invisible.
Note: The DD35 switcher provides an application setup, so that this logic
can be reversed on a effect basis.
When contents of the image that is used for the transition has quick motion, it may
be noticeable that the motion is slightly distorted on start and end of the transition.
That is due to the 1 frame delay through the DVE.
It can be avoided when – additionally to Transition Type DVE – the Loop function
is activated. Then, as long as Loop is On, the signal looped through the DVE is
used.
It is possible but not recommended to overwrite the selections made in the Transi-
tion Panel by making selections in the Pre-Processed Signal selection group of the
AUX Buses Panel. The resulting image may look peculiar.
