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

Specify the duration for which data may be recorded before
either the REC buttonis pressed.
