Recording and Playback: PRE-RECORDING function
The internal memory of your unit is capable of storing
several seconds of video and sound data coming from the
camera. This capability can be used to record video and
sound several seconds before either the REC button is
pressed to start recording. To use this function, the menu
option PRE REC MODE must be set to “ON”. The storage
duration of the internal memory can be set from the menu
option PRE REC TIME. These menu items are found in the
<REC FUNCTION> screen on the SYSTEM SETTING page.
The function of the menu option PRE REC MODE may be
assigned to a desired user button by using any one of the menu
options USER MAIN SW, USER1 SW, USER2 SW, SHOT
MARK (USER3) SW or TEXTMEMO (USER4).
These menu items are found in the <USER SW> screen on
the CAM OPERATION page.
These are the options for PRE REC TIME.

(When recording in DVCPRO50 in HD or SD mode)
1-15 SEC
(When recording in DVCPRO or DV in SD mode)
Specify the duration for which data may be recorded before
either the REC buttonis pressed.

z “P-REC” indication when the “PRE REC MODE” menu
option is set to OFF

z Immediately after the power is turned on, the menu option
PRE REC TIME is selected and/or the storage duration is
changed, the content in internal memory will be undefined. In
these situations, the video or sound will not be recorded for
the duration specified, even if the REC button is pressed to
start recording.
z A P2 card that has been just inserted takes some time to
recognise. In this situation, video or sound may not be
recorded for the duration specified, even if the REC button is
pressed to start a recording.

playback or recording review is being performed. For this
reason, no video or sound can be recorded during such
operation.

be shown as “HOLD” until the P2 card has been recognised.
