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).
