Chapter 4 Shooting — Selection of external reference signal and generator lock setting
Selection of external reference signal and generator lock setting
Locking the video signal to the external reference signal
The video signal output from the camera can be locked to the reference signal supplied from an external source.
The camera can receive external reference signals from the <GENLOCK IN> terminal.
Genlocking to the reference signal supplied from the <GENLOCK IN> terminal
HD-Y or composite signal that suits the system frame frequency is supplied to the <GENLOCK IN> terminal. Select the output signal to lock to the input
reference signal in the main menu

NOTE
t
In the system mode of 1080i/P or 720P, a genlock is applied to the video signal when the HD-Y signal is input. In this case, time code may shift by one
frame.
t
Down converter output refers to the output from the <MON OUT> and <SDI OUT/IN (OP)> terminals.
t
When the system mode is 1080/23.98PsF, the setting is fixed to [HD SDI] regardless of the settings of [GL PHASE].
