Chapter 9 Other Useful Functions — 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
You can switch to [REC RUN] and [FREE RUN] with the control panel.
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
recorded slaved to the time code input to the <TC IN/OUT> terminal.
f
[REC RUN]: Advances only while recording. The recording is started with the value continuing from the last time code of previous recording.
@ @
NOTE
t
In the following case, the values are not continuous.
- 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 SDI signal.
f
VITC UB: Recorded as VITC. It is also output as VITC of the 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
Duration (clip length) counter
This counter counts from 0 each time recording starts.The duration of the recorded clip is displayed after recording.
r
Date/time (real time)
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 34).
User bits settings
Sets the user bits to be recorded in the sub code area with the control panel.
Item Description
[FRAME RATE] Records the camera photo frame rate information.
The frame rate information same as the VITC UB is output when playing back the clip recorded with the system frequency
anything other than [50.00p], [59.94p], [50.00i], or [59.94i]. Use at this setting when the editing device such as a computer uses
the frame rate information of the user bits.
[USER]
Records internal user values. The user value can be set from [MENU] → [REC SETTINGS] → [TC] → [SET UB], the user value
can be set. Setting values are held even when the power is turned off.
For details, refer to “How to input user bits” (page 101).
[EXT INPUT] Records the user bits values currently entered to the <TC IN/OUT> terminal.
[TIME]
Records the time measured by the internal clock.
[DATE] Records the time digit of year/month/day/time measured by the internal clock.
[USER CLIP NAME (TYPE3)]
A numeric value of CAM INDEX (1 character) and REEL number (3 digit number) from left, each converted to ASCII character
code is recorded when the [USER CLIP NAME] is recorded as [TYPE3].
F is recorded in every digit when it is [TYPE1] or [TYPE2].
Only the value of when the recording has started is output for playback even when an item that changes in real time such as [TIME] is recorded in the
ProRes format.
How to input user bits
By setting user bits, information such as memos (date, time) up to eight digits long (hexadecimal) can be recorded.
1
Set [MENU] → [REC SETTINGS] → [TC] → [UB MODE] to [USER].
2
From [MENU] → [REC SETTINGS] → [TC], select [SET UB].
The user bits setting screen is displayed.
3
Set the user bits using the jog dial button.
Set them by two digits for each.
4
Press the jog dial button to confirm the user bits setting value.
@ @
NOTE
t
If you exit the user bits setting screen without pressing the jog dial button, the set values will be disabled.
