Chapter 4 Shooting — Setting the time data
Setting the time data
The camera provides time codes, user bits, and date and time (real time) data as time data, and they are recorded in the frame in sync with video. They
are also recorded as data for clip metadata files.
Definition of time data
r
Time code
Rec run and free run can be switched by [TC_MD] in the [SET01:TC/UB] screen of SmartUI.
f
[F-RUN]:
The time code always advances even when the power is turned off, and it can be handled in the same way as the actual time. It can also be
slaved to the time code input to the <TC IN/OUT> terminal.
f
[R-RUN]:
The time code advances only during recording. The number of the previously recorded clip is usually succeeded. The counter value is held
even after the camera is turned off or the P2 card to be recorded to is removed.

NOTE
t
In the following case, the values are not continuous.
- When deleting recorded clips
- When switching to 24PN and 30PN (25PN)
- When recording is interrupted due to a malfunction of [REC WARNING], etc. during recording.
r
User bits
Two types of user bits are built in.
f
LTC UB: Recorded as LTC and output from the <TC IN/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.
LTC UB 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/OUT> terminal, etc.
VITC UB records the camera frame rate information.
The LTC UB value of the recording start time can be recorded on the user bits of the clip metadata.
r
Date/time (real time)
f
By means of the internal clock, year, month, day, and time can be displayed on the viewfinder and on the output image of the <MON OUT> terminal,
etc.
f
The internal clock is used for measuring the free run time code while the power is off and as time and year/month/day data of the user bits. It is also
used as the reference for file 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 and UMID (Unique Material Identifier).
For details, refer to “Setting the date/time of the internal clock” (page 41).
