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 <GL IN/VIDEO OUT> terminal.

Genlocking to the reference signal supplied from the <GL IN/VIDEO OUT> terminal

HD-Y or composite signal that suits the system frame frequency is supplied to the <GL IN/VIDEO OUT> terminal. Select the output signal to lock to the input reference signal in the main menu → [IN/OUT SEL] → [GENLOCK SETTING] → [GL PHASE] (not available for 480i, 576i).

Adjust the horizontal phase of the reference signal and output signal in the main menu → [IN/OUT SEL] → [GENLOCK SETTING] → [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 → [IN/OUT SEL] → [GENLOCK SETTING].
