COMBINER INDEX CARD
Index card with two pages:
Page General
Opacity
Opacity for local channel.
Z–Offset
Z–offset for this channel. Only effective if the priority for
this channel is set to Z–key in the Priority index card.
Page Background Blacklevel
Chan 1 ... 4
black / superblack
Every time you change the architecture for your effect (single, pair1/2, pair3/4, tri-
ple, quadruple), the background blacklevels for the according channels are set au-
tomatically:
D
For single to superblack (allowing to work with just one output without a key
channel).
D
For pair1/2, pair3/4, triple, quadruple to black (using 2 outputs – video+key)
If you have a fully equipped FX processor without RAM output option – that means
only DVX1 ... 4 as outputs available – you can have e.g. two pairs with superblack
on DVX1 and DVX3, using DVX2 and DVX4 as RAM recorder outputs at the same
time. Overwrite chan1 and chan3 to superblack AFTER you have set your architec-
ture.
