Chapter 4 Adjustments and Settings for Recording Setting Time Data The camera provides time data such as time codes, user bits, time of day (real-time) data, which is recorded on each frame alongside video data. It is also recorded as as data in clip metadata 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 DVCPRO/DV 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 or 30PN is selected • When a recording is interrupted by a REC WARNING or other abnormality User bits • Two types of user bits are provided internally: (LTC UB: recorded as LTC, output via the TC OUT connector as LTC embedded in HD SDI) and VITC (in DVCPRO recorded in the VIDEO AUX area and output as VITC embedded in HD SDI). • LTC UB enables the recording of user settings, time, date, time codes and similar values, the frame rate data for camera capture and external input values (via TC IN or DVCPRO/DV connector input). • VITC user bits record the frame rate data of camera capture. • The user bits in clip metadata record the LTC UB value at the 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 for generating clip metadata and UMID (Unique Material Identifier). For details, see [Setting Date and Time of Internal Clock] (page 26). 56

Chapter²´² Adjustments²and²Settings²for²Recording
Setting Time Data
The camera provides time data such as time codes, user
bits, time of day (real-time) data, which is recorded on each
frame alongside video data. It is also recorded as as data
in clip metadata 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
DVCPRO/DV 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 or 30PN is selected
• When a recording is interrupted by a REC WARNING or other
abnormality
User bits
• Two types of user bits are provided internally: (LTC UB:
recorded as LTC, output via the TC OUT connector
as LTC embedded in HD SDI) and VITC (in DVCPRO
recorded in the VIDEO AUX area and output as VITC
embedded in HD SDI).
• LTC UB enables the recording of user settings, time,
date, time codes and similar values, the frame rate data
for camera capture and external input values (via TC IN
or DVCPRO/DV connector input).
• VITC user bits record the frame rate data of camera
capture.
• The user bits in clip metadata record the LTC UB value at
the 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 for generating clip metadata and UMID
(Unique Material Identifier).
For details, see [Setting Date and Time of Internal Clock]
(page 26).
