Grass Valley DD35 Family v.3.1.5 - Manual (Page 67)

2. Panel Operation DD35 Production Switcher
2 – 33 Operating Instructions – Rev. 16 / 10.2001
Note:
By selecting DVE as transition type it is possible to carry out wipe transitions using
external DVE effects. These effects may also be controlled from the Fader in the
machine control section.
Notes on building an effect for DVE transitions:
A DVE transition on the DD35 uses an effect built on the DVE unit as a transition.
This effect is built from keyframes, in order to obtain the desired result it is important
to note the following points:
D
With timecode based DVEs:
Set the effect duration to
Sony DME, Questech Charisma TEN-X: 2 min (i.e. sequence runtime is
3000/3600 frames for 525/625 standards, respectively) or
Pinnacle DVExtreme: 30sec (i.e. sequence runtime is 600/750 frames for
525/625 standards, respectively)
D
For the initial keyframe, set the image size to full screen size. For the final key-
frame, move the image off the screen, or reduce size to zero, so that it cannot
be seen on the screen.
2.6.3.4 Moving the DVE without doing a transition
The DVE effect can also be moved using the Fader or AUTO with the MiscFunc-
tion facility (to be found in the M/E menu).
The DD35 production switcher has – like most other switchers – visible image com-
ponents (BGD-A, BGD-B, Key1, Key2, (Key3)). Additionally, the DD35 has invis-
ible image components for flexible control purposes. These are called Misc 1 and
Misc 2, and treated logically as if they were Key components i.e. can be mixed in
and out, value is between 0% and 100%. They can also be selected for Next Tran-
sition. The speciality of these components is: for each of these components, the
user can select a function – the MiscFunction – that is controlled by the compo-
nent.
The following example shows how to use this facility to move a DVE:
D
In the M/E menu, use the softkey Misc 1 or Misc 2 to define the DVE as the
function to be controlled by the invisible components Misc 1 or Misc 2.
D
Activate Next Trans for Misc 1 or Misc 2.
D
The DVE will move through its effect when the Fader is moved or AUTO is
pressed. With CUT it will be set to the other end.
Because in this way no transition of a visible component is done, no restriction must
apply to the effects that can be used. The first and last keyframe need not to be at
a special value.
Also, since the FXLoop is not necessary, both DVEs can be moved using the same
Fader.
Of course, the DVE movement can be combined with a transition in any visible
component.
