Chapter 4 Shooting — Setting the time data
t
For all devices, set the main menu
→
[IN/OUT SEL]
→
[TC OUTPUT REF] to [RECORDING], and the main menu
→
[IN/OUT SEL]
→
[GENLOCK
SETTING]
→
[GL PHASE] to [COMPOSITE].
t
If you set [RECORDING] in the main menu
→
[IN/OUT SEL]
→
[TC OUTPUT REF], the two cameras will be able to record with the same time code in
the image.
t
The subcarrier of the composite signal out from the <GL IN/VIDEO OUT> terminal of the camera cannot be externally locked.
External lock operation procedure
To externally lock the time code, follow the steps below.
1
Set [TC IN] in the main menu
→
[IN/OUT SEL]
→
[TC IN/OUT SEL].
2
Press the <SETUP> button to display the [SET01:TC/UB] screen of SmartUI.
3
Press the <COUNTER> button to set the counter display to [TC].
4
Press the <STOP> button to set [TC_MD] to [F-RUN].
5
Input a reference time code and reference video signal that are in a phase relationship (that conforms to time code specifications)
to the <TC IN/OUT> terminal and the <GL IN/VIDEO OUT> terminal.
The built-in time code generator is locked to the reference time code. When approximately ten seconds has elapsed after locking, the external lock
status will be held even if the reference time code from the external device is disconnected.
f
When the input reference signal of genlock is disrupted, recording cannot be performed normally. [TEMPORARY PAUSE IRREGULAR SIG] is
displayed in the viewfinder, and the clip is divided. The continuity of the time code is not guaranteed. Recording will be resumed when the signal
returns to normal. However, during loop recording, recording does not resume.
f
When external lock is performed, the time code is instantaneously locked to the external time code, the same value as the value of the external
time code is output to the counter display area, and the [TCG[R]] display is black and white inverted. Do not set to the recording mode for several
seconds until the sync generator has stabilized. Also, lock the time code to the <TC IN/OUT> terminal signal.
f
When using the camera with [ON] set in the main menu
→
[RECORDING SETUP]
→
[PRE REC], disrupted images or stopped time codes may
be recorded if the time code is switched from recording run to free run immediately before recording or an external time code is input to be slave-
locked to the <TC IN/OUT> terminal.
f
Once the slave is executed, it will maintain the slave status even if the input to the <TC IN/OUT> terminal or the <GL IN/VIDEO OUT> terminal is
lost. However, in the following cases, the slave status will be released.
- When time code is set on the [SET01:TC/UB] screen of SmartUI
- When the power is turned off
- When switching between [DF]/[NDF] in [DF MODE]
- When [TC_MD] is set to [R-RUN] on the [SET01:TC/UB] screen of SmartUI
- When switching between [REC FORMAT] and [CAMERA MODE]
Setting of user bits when the time code is externally locked
To lock user bits to the input values from an external source, set the main menu
→
[RECORDING SETUP]
→
[UBG MODE] to [EXT]. Regardless of the
setting of recording run/free run, it is slaved to user bits values input to the <TC IN/OUT> terminal.
Canceling the external lock
After stopping supply of the external time code, set the main menu
→
[RECORDING SETUP]
→
[UBG MODE] to other than [EXT].
Cautions when switching the power supply from the battery to the external DC power supply while an external lock
is active
To keep on the time code generator power supply continuously, connect an external DC power supply to the <DC IN> terminal and then remove the
battery pack. If the battery pack is removed first, there is no guarantee that the time code will stay externally locked.
External synchronization of the camera unit while an external lock is active
The genlock will be applied to the camera unit by the reference video signal input to the <GL IN/VIDEO OUT> terminal while the external lock is applied.

NOTE
t
To externally lock multiple units with the camera as the master device, set to the same setting as on the camera. Note that in a system using a mixture
of interlaced and progressive scanning, the continuity of the video and time codes is not guaranteed.
t
When externally locking in 24PN Native mode, be sure to input non-drop frame time codes. An external lock is not possible using drop frames. Also,
images may be disrupted the instant that the external lock is activated, though this is due to alignment of the 5-frame cycle and is not a malfunction.
