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/VIDEO OUT> terminal.
Generator-locking to the reference signal supplied from the <GENLOCK IN/VIDEO OUT> terminal
HD-Y or composite signal that suits the system frame frequency is supplied to the <GENLOCK IN/VIDEO OUT> terminal. To enable the reference signal
input to the <GENLOCK IN/VIDEO OUT> terminal, the <IN/OUT> switch needs to be set to <IN>. The output signal to be locked to the input reference
signal can be set in the main menu → [OTHER FUNCTIONS] → [GL PHASE] (only in 1080/59.94i and 1080/50i).
Adjust the horizontal phase of the reference signal and output signal in the main menu → [OTHER FUNCTIONS] → [H PHASE].

NOTE
t The subcarrier of the composite signal of the camera is not locked to the subcarrier of the reference signal.
Output status
The output status changes as follows according to selection of the external reference signal and generator lock setting.
Set [GL PHASE] in the main menu → [OTHER FUNCTIONS].

NOTE
t In the system mode of [1080P], 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 <GENLOCK IN/VIDEO OUT> and <SDI OUT> terminals.
