Selecting your genlock source
Genlock options for DigiSuite LX without the digital
module
When DigiSuite LX is the genlock master (that is, you don’t have the
optional digital module), you can select one of the following genlock
options:
✃
External Broadcast Quality
Genlock to an external sync generator
connected to REF IN on DigiSuite LX. This is the only genlock option
that ensures frame-accurate editing.
✃
External VTR Quality Genlock to your source VTR connected to
REF IN on DigiSuite LX, such as your composite VTR. This option is
preferable to using the internal reference signal on DigiSuite LX if
you don’t have an external sync generator.
✃
Internal Genlock to DigiSuite LX’s internal reference signal. Select
this option only if you don’t have an external sync generator or other
external video sync source.
Genlock options for DigiSuite LX with the digital
module
When the optional digital module is installed for DigiSuite LX, you can
select one of the following genlock options:
✃
Blackburst (REF IN)
Genlock to an external analog sync source
connected to REF IN on the digital module, such as an external sync
generator.
✃
4:2:2 (SDI)
Genlock to your digital input source. Use this option
only if your digital input source is very stable (that is, it has a built-in
TBC).
✃
Internal
Genlock to the digital module’s internal reference signal.
Select this option only if you don’t have an external sync generator or
other reliable external video sync source.
