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 <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].

NOTE
t The subcarrier of the composite signal of the camera is not locked to the subcarrier of the reference signal.
t To set the <GL IN/VIDEO OUT> terminal for genlock input, go to the main menu → [IN/OUT SEL] → [GL IN/VIDEO OUT SEL], and select [GENLOCK
IN].
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].

[HD SDI]
HD SDI output matches the HD-Y input signal.
Down converter output has a delay of approx. 90 H from the HD-Y input
signal.
[COMPOSITE]
Down converter output matches the HD-Y input signal.
HD SDI output has an advance of approx. 90 H from the HD-Y input
signal.
Composite
[HD SDI]
HD SDI output matches the composite input signal.
Down converter output has a delay of approx. 90 H from the composite
input signal.
[COMPOSITE]
Down converter output matches the composite input signal.
HD SDI output has an advance of approx. 90 H from the composite
input signal.

Down converter output has a delay of approx. 120 H from the HD-Y
input signal.
[COMPOSITE]
Down converter output matches the HD-Y input signal.
HD SDI output has an advance of approx. 120 H from the HD-Y input
signal.
Composite
[HD SDI]
HD SDI output matches the composite input signal.
Down converter output has a delay of approx. 120 H from the composite
input signal.
[COMPOSITE]
Down converter output matches the composite input signal.
HD SDI output has an advance of approx. 120 H from the composite

480i, 576i
Composite —
SD SDI output matches the composite input signal.
Composite output matches the composite input signal.
HD-Y —
SD SDI output is not locked to the HD-Y input signal.
Composite output is not locked to the HD-Y input signal.

NOTE
t The video signal will have genlock when the HD-Y signal is input if the system mode is 720P. In this case, time code may shift by one frame.
t The down converter output represents the output from the <SDI OUT2/IN> terminal.
t When the system mode is 1080/23.98PsF, the genlock can be applied only for HD-Y signal. In this case, regardless of the [GL PHASE] setting, HD
SDI signal output is matched with HD-Y signal.
