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
connector 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 24PN or 30PN (25PN) 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 and
VITC.
•
LTC user bits enable 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 connector input). They are output from the TC OUT
connector or output as LTC embedded in HD SDI.
•
VITC user bits record the frame rate data of camera
capture. They are output as VITC embedded in HD SDI.
•
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 output
on the LCD monitor, in the viewfinder, or embedded in
MONITOR OUT.
•
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).
