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 files.
Definition of time data
r
Time code
Rec run and free run can be switched by the [TC_MD] setting on the [SET01:TC/UB] screen of SmartUI.
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/OUT> terminal.
f
Rec run: The time code advances only during recording. Normally, the time code is recorded as sequential values to the previously recorded clip, and
is held even if the power is turned off or the P2 card is replaced.
@
@
NOTE
t
Values are not sequential in the following instances:
- When a recorded clip has been deleted
- When the 24P or 24PA frame rate has been switched to
- When 24PN or 30PN has been switched to
- When an error such as [REC WARNING] has stopped recording midway
r
User bits
f
Two types of user bits are built in: LTC UB (recorded as LTC, and output from the <TC IN/OUT> terminal and as LTC of HD SDI signals) and VITC UB
(with DVCPRO, recorded in the VIDEO AUX area, and output as VITC of HD SDI signals).
f
For LTC UB, you can select and record each respective user set values, time, year/month/day, with the same value as time codes, camera photo
frame rate information, input value of external signals (from the <TC IN/OUT> terminal), etc.
f
For VITC UB, the camera photo frame rate information is recorded.
f
The LTC UB value at the start of recording is recorded to the user bits of the clip metadata.
r
Date/time (real time)
f
The internal clock measures the year, month, day, and time, and can display these on the viewfinder screen and on the output video from 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 the time and year/month/day data of the user bits, as well
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 31).
