Luma Key Quick Set Up - Datavideo SE-3000 Instruction Manual

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.
