Chapter 4 Adjustments and Settings for Recording Setting Time Data This camera records time data such as the time code, user bits, date and time (real time) data in the subcode area, VIDEO AUX area and in clip meta data files. Time data overview Time code Use the TCG switch to select Rec Run or Free Run mode. • Free Run: The time code advances constantly whether the camera is on or not just like time itself. Recording using a slave-locked time code input to the TC IN or 1394 connectors is also possible. • Rec Run: The time code advances only during recording. This will enable continuation of time codes in previously recorded clips and when the power is turned off or new P2 cards are inserted to continue recording. The following events will disrupt time code continuity. • When clips are deleted • When a 24P or 24PA frame rate is selected • When 24PN, 30PN or 25PN is selected • When a recording is interrupted by a REC WARNING or other abnormality User bits • There are two types of user bits. The user bits (UB) that are recorded in the subcode area and the user bits (VITC UB) that are recorded in the VIDEO AUX area. • The subcode user bits enable the recording of user settings, time, date, time code and similar values, the frame rate data for camera capture, external input values (via TC IN or 1394 connector input). • VITC user bits record the frame rate data of camera capture. • The clip meta data user bit records the user bit values in the subcode area at start of recording. ■Date (real time) • The built-in clock calculates the year, month, day and time from the internal clock to display on video in the LCD, viewfinder and VIDEO OUT and other video output. • The internal clock is not only used to calculate the free run time code when the power is off and to set the user bit year, date and time, but also to set file creation dates when clips are recorded that determine the order of thumbnails and playback order. • It is also used to generate clip meta data and UMID in the VIDEO AUX area.

Setting Time Data
Chapter 4 Adjustments and Settings for Recording
Setting Time Data
This camera records time data such as the time code,
user bits, date and time (real time) data in the subcode
area, VIDEO AUX area and in clip meta data files.
Time data overview
Time code
Use the TCG switch to select Rec Run or Free Run
mode.
•
Free Run: The time code advances constantly
whether the camera is on or not just like time itself.
Recording using a slave-locked time code input to
the TC IN or 1394 connectors is also possible.
•
Rec Run: The time code advances only during
recording. This will enable continuation of time codes
in previously recorded clips and when the power is
turned off or new P2 cards are inserted to continue
recording.
<Note>
The following events will disrupt time code continuity.
• When clips are deleted
• When a 24P or 24PA frame rate is selected
• When 24PN, 30PN or 25PN is selected
•
When a recording is interrupted by a REC WARNING or
other abnormality
User bits
•
There are two types of user bits. The user bits (UB)
that are recorded in the subcode area and the user
bits (VITC UB) that are recorded in the VIDEO AUX
area.
•
The subcode user bits enable the recording of user
settings, time, date, time code and similar values, the
frame rate data for camera capture, external input
values (via TC IN or 1394 connector input).
•
VITC user bits record the frame rate data of camera
capture.
•
The clip meta data user bit records the user bit
values in the subcode area at start of recording.
■
Date (real time)
•
The built-in clock calculates the year, month, day and
time from the internal clock to display on video in the
LCD, viewfinder and VIDEO OUT and other video
output.
•
The internal clock is not only used to calculate the
free run time code when the power is off and to
set the user bit year, date and time, but also to set
file creation dates when clips are recorded that
determine the order of thumbnails and playback
order.
•
It is also used to generate clip meta data and UMID
in the VIDEO AUX area.
For details, see [Setting Date and Time of Internal
Clock] (page 28).
