Chapter 3 Preparation — Setting of time data
Time code with variable frame rate record
The time code is fixed to [REC RUN] when the variable frame rate recording function is set to enable. The time code will advance in the speed
corresponding to the ratio setting values of [FREQUENCY] (system frequency) and [FPS] (frame rate).
As an example, the time frame will advance 60/24 frames (two seconds 12 frames) per second when [FREQUENCY] is set to [24.00p] and [FPS] is set
to [60fps].
f
The time code output from the <TC IN/OUT> terminal or the <SDI OUT> terminal is advanced in 1x speed from the exact start of recording.
Presetting the time code to external
The internal time code generator of the camera can be slave locked in a simplified manner to an external generator.
Connection example of the camera and an external generator
Connect the reference time come to the <TC IN/OUT> terminal.

[FREQUENCY] as the reference time code.
Also, enter the time code of the non-drop frame for 23.98p, 24.00p, 25.00p, 50.00p, and 50.00i.

NOTE
t
Do not slave lock to the externally input time code but automatically advance with internal reference during recording or rec remote controlling of
the external recording device.
The time code value may overlap or drop out after recording or ending rec remote due to performing slave lock to the time code input from
external.
t
Since this camera does not have a genlock system, the time code may shift one frame.
t
Once the slave lock is performed, it will maintain the slave lock status even when the input from the <TC IN/OUT> terminal is gone. However, the
slave lock status will be cleared in following cases.
- When the time code is set in [SET TC]
- When the power is turned off
- When switched [DF]/[NDF]
- When set to [REC RUN]
- When the variable frame rate recording function is enabled
t
The pre-recording will be discarded once when the slave lock is performed during pre-recording.
t
The number of frames for the record start time code may not be multiple of four when [FREQUENCY] is set to 23.98p or 24.00p.
t
External locks by user bits are not supported.
Cautions when switching the power supply from the battery to the AC adaptor while an external lock is active
To maintain the continuity of the time code generator power, remove the battery only after that the power status display in the HOME screen has
changed to
after connecting the AC adaptor to the <DC IN 12V> terminal. The continuity of the external lock of the time code is not guaranteed
when the battery is removed first.
