Synchronizing with an External Device
98
NOTES NOTES
• Synchronize the camera’s time code with an external time code signal that matches the camera’s system
frequency. Use a 24-frame time code signal when the frame rate is set to 23.98P or 24.00P, a 25-frame time
code signal when it is set to 25.00P, 50.00i or 50.00P and a 30-frame time code signal for other frame rates.
• When a suitable external time code signal is received, the camera’s own time code will be synchronized to it
and the synchronization will be maintained even if you disconnect the cable from the TIME CODE terminal.
• If the external time code signal is incorrect or there is no input signal, the internal time code set in the camera
will be recorded instead.
• When an external time code signal is received, the DF/NDF selection will follow the external time code signal’s
settings.
• If an external time code signal is input while pre-recording is activated, there might be a discontinuity in the
time code of the pre-recorded clip.
• Performing any of the following actions while the cable is not connected will cause the synchronization to be
disrupted; the correct time code will be restored once you reconnect the cable.
- Turning the camera on/off
- Switching to MEDIA mode
- Changing the video configuration
Time Code Signal Output
The time code signal output from the TIME CODE terminal will be a SMPTE-standard LTC timing signal. The user
bit will also be output.
Select > [
B
System Setup] > [TC In/Out] > [Out].
NOTES NOTES
•
About the user bit output:
In CAMERA mode, the user bit set by the user (
A
96) will be output. In MEDIA mode,
the user bit is not output from the TIME CODE terminal.
• The time code and user bit will not be output when slow & fast motion recording is activated.
Reference Video Signal Input (Genlock Synchronization)
When a reference sync signal (analog blackburst or tri-level signal) is input through the optional EU-V1’s or
EU-V2’s G-LOCK/SYNC OUT terminal, the phases of the camera's V and H sync will automatically be
synchronized to it. The phase difference between the external Genlock signal and the camera is initially set to 0.
The H phase can be adjusted within the range of approximately ±0.4 H.
1 Select > [
B
System Setup] > [G-LOCK/SYNC Term.] > [Genlock Input].
2 Select > [
B
System Setup] > [Genlock Adjustment] > [Change].
• To reset the adjustment value to [000], select [Reset] instead.
3 Enter the H-phase adjustment value using the data entry screen (
A
60).
NOTES NOTES
• When a suitable Genlock signal is input, the Genlock synchronization stabilizes after approximately
10 seconds.
• When a suitable Genlock signal is detected, the
U
icon will flash at the top right of the screen. When the
camera locks on the external Genlock signal, the icon will stay on.
