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).

For details, see [Setting Date and Time of Internal Clock] (page 28).
