Locking the video signal to the external reference signal
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
The HD-Y signal or a composite signal matching 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>. Select the output signal to lock to the input reference signal from the main menu → [OTHER FUNCTIONS] → [GL PHASE] (in 1080i, 1080P, and 720P only).
Adjust the horizontal phase of the reference signal and output signal in the main menu → [OTHER FUNCTIONS] → [H PHASE].
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].
