3.14.5.9 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 want to use superblack also for the more channel effects, you can overwrite
it here AFTER you have set your architecture
