Luma Key Quick Set Up
For this example we will be supplying the SE-3000 with a HD-SDI background feed on
input 10
. We will
select the
STILL
button on the
Aux Bus row
and this will be used for Luma keying a static white shape over
the video from input 10. We have already assigned a still with a black/dark background and white or light
coloured text to the
STILL1
buffer – see
Loading an existing still from memory
on page 28
.
Step 1:
Choose the Keyer channel that
you want to use. For our example we
will press the
Key 2 button
in the
Aux
Bus Delegates
button group.
Step 2:
Choose the type of Keyer you
want to use. In our example we will
press the
Luma button
in the Keyer
Controls button group.
Step 3:
Select the foreground video source to be keyed. In our example we want to use the
STILL 1
source
to overlay some text. So we would press
STILL
on the
Aux Bus Row
so it is
backlit Green
. We have also
chosen button 10 on the Program row as our background video.
Step 4:
Turn the keying effect on.
Press the
On button
so it is backlit
green. In our example you will now see
the selected source button
STILL
, on
the
Aux Bus Row
change so it
is now
backlit Red
.
Step 5
: Make some adjustments to the
Luma key. Press the
Keyer button in
the Menus button group
and look at
the Touch Screen Menu Panel.
The options along the bottom of the
Touch Screen will now allow you
to
calibrate for a white or black key
using the
F1~F3 Function Dials or
the Touch Screen.
The following section will explain the
effects of
Lift
,
Gain
,
Opacity
and
Invert.
