Chapter 3 Operation — Adjustment for shooting
Genlock adjustment
The video signal output from the camera can be locked to the reference signal supplied from an external source.
This camera can receive the external reference signal from the <G/L IN> terminal or the <I/F> terminal.
Supply HD-Y signal or composite signal matching the frame frequency of the system to the <G/L IN> terminal or the <I/F> terminal.
1
Select [MAIN MENU] → [IN/OUT SELECT] → [GEN-LOCK].
2
Select the input source of the synchronization signal in [GEN-LOCK INPUT].
3
Coarsely adjust the phase of the synchronization signal input and the video signal output in [H PHASE-COARSE].
4
Finely adjust the phase of the synchronization signal input and the video signal output in [H PHASE-FINE].
@ @ NOTE
t
Genlock can be applied only with the HD-Y signal when the system mode is set to [2160/23.98p] or [1080/23.98PsF].
t
Genlock can be applied with the HD-Y signal or the composite signal for [1080/59.94i] when the system mode is set to [1080/23.98p].
t
Genlock can be applied with the HD-Y signal or the composite signal for [1080/59.94i] or [1080/50i] when the system mode is set to 2160p or 1080p
other than described above.
Shutter mode
Fixed shutter speed
This is used in the following cases.
f
To eliminate flickers caused by illumination
f
To clearly shoot the fast moving subject
Synchro scan mode
This is used in the following cases.
f
To shoot with less horizontal banding when shooting the monitor screen
f
To shoot with effect in the motion of the subject
Shutter mode/speed setting
It is possible to limit the range of shutter speed selection or to use the synchro scan mode in advance with [MAIN MENU] → [SWITCH MODE] →
[SHUTTER SPEED] → [SHUTTER SPEED]/[SHUTTER MODE].
The selected shutter speed will be maintained even after the power of the unit is turned off.
@ @ NOTE
t
Whichever mode the electronic shutter is used in, the higher the shutter speed, the lower the sensitivity of the camera becomes.
t
When the aperture is in the automatic mode, it will increasingly open and the depth of focus will become shallower as the shutter speed is increased.
t
Under lighting conditions using fluorescent lighting or other discharge tube, horizontal stripes might appear on screen. If this happens, this can be
improved by adjusting the shutter speed.
t
A subject that quickly crosses the camera may appear distorted when shot. This is due to the method applied for reading the signals from the pickup
device (MOS sensor), and is not a malfunction.
t
The shutter mode is turned off when the intelligent function is operating.

Synchro scan mode setting
1
Set it to [MAIN MENU] → [SWITCH MODE] → [SHUTTER SPEED] → [SHUTTER MODE] → [SYNCHRO].
2
Set the shutter for the synchro scan in [MAIN MENU] → [SWITCH MODE] → [SHUTTER SPEED] → [SYNCHRO SCAN].
The shutter speed display of the synchro scan mode can be switched between second and angle in [MAIN MENU] → [SWITCH MODE] →
[SHUTTER SPEED] → [SYNCHRO SCAN DISP].
