Setting Time Data; Time Data Overview - Panasonic AG-HPX500 Operating Instructions Manual

Setting Time Data

This camera records time data such as the time code,
user bits, date and time (real time) data in the subcode
area, VIDEO AUX area and in clip meta data 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 or 1394 connectors 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 a 24P or 24PA frame rate is selected
• When 24PN, 30PN or 25PN is selected
• When a recording is interrupted by a REC WARNING or
other abnormality
User bits
• There are two types of user bits. The user bits (UB)
that are recorded in the subcode area and the user
bits (VITC UB) that are recorded in the VIDEO AUX
area.
• The subcode user bits enable the recording of user
settings, time, date, time code and similar values, the
frame rate data for camera capture, external input
values (via TC IN or 1394 connector input).
• VITC user bits record the frame rate data of camera
capture.
• The clip meta data user bit records the user bit
values in the subcode area at start of recording.

Setting Time Data
■Date (real time)
• The built-in clock calculates the year, month, day and
time from the internal clock to display on video in the
LCD, viewfinder and VIDEO OUT and other video
output.
• 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 to generate clip meta data and UMID
in the VIDEO AUX area.

Clock] (page 28).
