External Synchronization
When shooting using multiple camcorder
units, the camcorders can be synchronized to
a specific reference signal or timecode via the
genlock connector of the camcorders.
Synchronizing the Phase of the
Video Signals (Genlock)
Set the IN/OUT select switch (page 8) of
the camcorder to the IN position, and supply a
reference signal to the GENLOCK IN/REF OUT
connector (page 8) to enable genlock.
The reference signals that can be used vary
depending on the system frequency of the
selected recording format.

[Notes]
If the reference signal is unstable, genlock cannot be
achieved.
The subcarrier is not synchronized.
Locking the Timecode to Other
Devices
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 (page 90) in the TC/
Media menu as follows.
Mode: Preset
Run: Free Run
2 Press the assignable button (page 41)
assigned with the DURATION/TC/UBIT
function to display the timecode on the
screen.
3 Check that the IN/OUT select switch
(page 8) is set to the IN position, then
supply an HD or SD reference video signal
to the GENLOCK IN/REF OUT connector
and the reference timecode to the TC IN/
OUT connector.
The timecode generator of the camcorder
acquires lock with the reference timecode, and
“EXT-LK” appears 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.
To release external lock
Change the Timecode setting in the TC/Media
menu, or turn the camcorder off.
External synchronization is also released if the
system frequency is changed and when you
start recording in a special recording mode
(Slow & Quick Motion or Interval Rec).
Synchronizing the Timecode of
Another Device with the Timecode
of the Camcorder
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 the timecode of the camcorder using
Timecode (page 90) in the TC/Media
menu.
2 Check that the IN/OUT select switch
(page 8) is set to the OUT position,
and connect the TC IN/OUT connector
and GENLOCK IN/REF OUT connector to
the timecode input and reference signal
input, respectively, of the device you want
to synchronize.
