2-4 Setting Reference Video Signals
This section explains how reference video signals for
synchronization of video output and servo lock are
selected according to settings made with this unit.
Reference video signal for video output
Output video signals are synchronized with the signal
generated by this unit’s internal reference video signal
generator. The internal reference video signal
generator can be synchronized with an external
reference video signal or with an input video signal
(SDI or composite video).
Reference video signal for servo lock
synchronization
Servo lock can be synchronized with an external
reference video signal, with an input video signal (SDI
or composite video), or with the signal generated by
this unit’s internal reference video signal generator.
As shown in the table below, a signal for
synchronization of the internal reference video signal
generator and a reference video signal for
synchronization of servo lock are selected according to
the setting of setup menu item 309, the setting of the
OUT REF in the submenu, and the operating mode of
the unit.
For more information about setup menu item 309, see page
6-11. For more information about the OUT REF, see page
2-22.

Reference video signals in editing
When the OUT REF is set to REF, the signal shown in
the table below is selected, depending on whether
setup menu item 309 is set to AUTO1 or AUTO2.
Note
Normally select AUTO1 and synchronize the external
reference video signal with the input video signal.
Select AUTO2 when the external reference video
signal is not synchronized with the input video signal.
If you select AUTO1 under these conditions, noise
may enter the video and audio signals, making editing
difficult.
