Chapter 4 Adjustments and Settings for Recording — Setting the time data
Setting the time data
The camera provides time codes, user bits, and date/time (real time) data as time data, and they are recorded in frame in sync with video. They are also
recorded as data for clip metadata les. A CTL counter and camera ID are built in.
Denition of time data
r Time code
Recording run and free run can be switched by the <TCG> switch.
f Free run: The time code always advances even when the power is turned off, and it can be handled in the same way as time. It can also be slaved to
the time code input to the <TC IN> terminal.
f Recording run: The time code can be regenerated to the time code of clips recorded to P2 cards and recorded as a continuous value.
r User bits
Two types of user bits are built in.
f LTC UB: Recorded as LTC and output from the <TC OUT> terminal. It is also output as LTC of the HD SDI signal.
f VITC UB: Recorded as VITC (recorded to VIDEO AUX area by DVCPRO). It is also output as VITC of the HD SDI signal.
You can select and record user set values, time, year/month/day, the same value as time codes, camera frame rate information, and input value of
external signals from the <TC IN> terminal, etc., respectively.

NOTE
t Only one type of user set values is recorded.
t In the [720P] mode, when the frame rate of [REC FORMAT] is set to 30P/25P/24P, VITC UB is xed to the frame rate information. For details, refer to
“Recording and output of time codes and user bits”.
r Date/time (real time)
f The internal clock measures the year, month, day, and time, and the built-in GPS function can correct the internal clock with the accurate date and
time.
f The internal clock is used for measuring the free run time code while the power is off and as the time and year/month/day data of the user bits. It is
also used as the reference for le generation times during clip recording, which determine the sorting order of thumbnails and the order of playback.
f It is also used to generate clip metadata.
For details, refer to “Setting the date/time of the internal clock” (page 30).
r CTL counter
f During recording, the CTL counter measures the total recording time since the last reset. During playback, it is also the value for counting the
beginning of playable clips as a reference point. It can be used as a means for relatively learning the current playback position.
r Camera ID
f 10 characters x 3 lines can be set as the camera ID which can be recorded superimposed over the color bar image. It can also be recorded
superimposed simultaneously on the date/time data.

[REC FORMAT] indicates only frame rate. For example, [AVC-I100/60i] is 60i, and [AVC-G50/30PN] is 30P.

*3 In free run, the time code is converted to 24 frames and slaved when the input TC of the <TC IN> terminal is 30 frame non-drop frame. However, the time
code cannot be slaved during recording.
*4 In free run, the time code is slaved when the input TC of the <TC IN> terminal is a non-drop frame. However, the time code cannot be slaved during recording.
