External Synchronization - Sony PXW-FS7 Operating Instructions Manual

External Synchronization

When shooting using multiple camcorder units,
the camcorders can be synchronized to a specific
reference signal or timecodes synchronized via
the Genlock connector of the XDCA-FS7 units
(page 12) attached to the camcorders.
Note
The camcorder battery pack cannot be used when an
XDCA-FS7 unit is attached to the camcorder. You must
attach a battery pack to the XDCA-FS7 or connect an
external power supply.
Synchronizing the phase of the video
signals (genlock)
Enable genlock by supplying a reference signal to
the Genlock connector (page 12) of the
XDCA-FS7 units connected to the camcorders.
The reference signals that can be used vary
depending on the frame rate of the selected
recording format.

Notes
• If the selected recording format is 1280×720 60P, you
must supply both a video signal and a time signal.
• 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 in the TC/UB menu as
follows.
Mode: Preset
Run: Free Run
2
Press the assignable button (page 45)
assigned with the DURATION/TC/
U-BIT function to display the timecode
on the screen.
3
Check that the TC IN/OUT switch
(page 12) on the XDCA-FS7 is set to the
IN position, and supply an HD or SD
reference video signal and a timecode
synchronized to the video signal to the
Genlock and TC IN/OUT connectors,
respectively.
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.
