When multiple units of the PMW-EX3 are used in
the same shooting location, recording can be
made in synchronization with a specific reference
signal, and the timecode can be matched among
all the units.
Aligning the phase of the video signal
(Genlock)
Genlock operation is enabled by supplying an SD
or HD reference signal to the GENLOCK IN
connector of the camcorder.
If the video format is set to HQ 1080/24P, select
the sync mode (60i or 24PsF) with “Genlock”
of the OTHERS menu.
The phase adjustment for the reference signal can
also be made with “Genlock” of the OTHERS
menu.
Notes
• If the reference signal is unstable, genlock is not
possible.
• The subcarrier is not synchronized.
Synchronizing the timecode of your
camcorder with that of another unit
The timecode of your camcorder can be locked to
that of another unit.
Set the unit that supplies the timecode to a mode
in which the timecode output keeps advancing
(Free Run or Clock mode).
1
Set “Timecode” of the TC/UB SET
menu as follows:
Mode: Preset
Run: Free Run
2
Press the TC/U-BIT/DURATION
button so that the timecode is displayed
on the screen.
3
Supply an HD or SD reference video
signal to the GENLOCK IN connector
and the reference timecode to the TC IN
connector.
Thus the built-in timecode generator of your
camcorder locks to the reference timecode.
The message “EXT-LK” is displayed on the
screen.
After about 10 seconds, you can disconnect the
external timecode without losing the
synchronization.
Notes
• Check that the reference timecode and the
reference video signal are in a phase relation
that complies the SMPTE timecode standards.
• When you finish the above procedure, the
timecode is immediately synchronized with the
external timecode, and the time data indication
will show the value of the external timecode.
However, wait for a few seconds until the
timecode generator stabilizes before recording.
• If the frequency of the reference video signal is
not the same as the frame frequency of the
camcorder, the camcorder cannot be correctly
genlocked. In such a case, the timecode is not
correctly synchronized with the external
timecode.
• When the connection is removed, the timecode
advance may shift one frame per hour with
respect to the reference timecode.
