Sony XDCA-FX9 Extension Unit for PXW-FX9 Camera - Manual (Page 80)

When multiple units of the camcorder are used in
the same shooting location, recording can be
synchronized with a specific reference signal, and
the timecode can be matched among all the units.
Synchronizing the phase of the video
signals (genlock)
Genlock operation is enabled by supplying a
reference signal to the GENLOCK IN/VIDEO
OUT connector
(page 9) of the camcorder.
The reference signals that can be used vary
depending on the system frequency of the
selected recording format.
Notes
• Both video signal and timecode signal need to be input
when the selected recording format is 1280×720 60P.
• If the reference signal is unstable, genlock cannot be
achieved.
• The subcarrier is not synchronized.
Locking to the timecode of another
device
Set the unit that supplies the timecode to a mode
in which the timecode output keeps running (such
as Free Run or Clock).
1
Set Timecode in the TC/UB menu as
follows:
Mode: Preset
Run: Free Run
2
Press the DURATION/TC/U-BIT
button
(page 11) so that the timecode is
displayed on the screen.
3
Confirm that the IN/OUT switch
(page 9) is set to IN, then supply an HD
or SD reference video signal to the
GENLOCK IN/VIDEO OUT connector
and the reference timecode to the TC
connector.
The built-in timecode generator of your
camcorder locks to the reference timecode, and
“Ext LK” is displayed on the screen.
Once about ten seconds have elapsed after the
timecode locks, the external lock state is
maintained even if the external reference
timecode source is disconnected.
Notes
• Check that the supplied reference timecode and the
reference video signal are in a phase relationship that
complies with the SMPTE timecode standard.
• When operating with external lock, the timecode
instantly acquires lock with the external timecode and
the external timecode value appears in the data display
area. However, do not start recording immediately.
Wait for a few seconds until the timecode generator
stabilizes before recording.
• If the frequency of the reference video signal and the
frame frequency on the camcorder are not the same,
lock cannot be acquired and the camcorder will not
operate properly. If this occurs, the timecode will not
acquire successful lock with the external timecode.
• If the external timecode source is disconnected, the
timecode may shift by one frame per hour with respect
to the reference timecode.
