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 terminal. Generator-locking to the reference signal supplied from the terminal HD-Y or composite signal that suits the system frame frequency is supplied to the terminal. To enable the reference signal input to the terminal, the switch needs to be set to . 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).

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
