The recording will start from the top frame of a five-frame
cycle for 24P/24PA recording, a four-frame cycle for 24P
native recording or a two-frame cycle for 30P and 25P of
720P, respectively. Therefore, the time code may be
discontinued when recording clips continuously in
different modes during the recording cycle.
z
Even if a P2 card has just been inserted, or the power
has been just turned on, you can start recording using
the internal memory of camera-recorder. In this case,
recording cannot be stopped until the P2 card is
recognised. If the inserted card is not recognized as a
recordable P2 card, the record in internal memory is
instantly discarded, and the message “CANNOT REC”
message is displayed on the viewfinder. Press the
MODE CHECK button to check P2 card status
(displayed in viewfinder).
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 START/
STOP button, REC button on the handle or VTR button at
the lens 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. PRE REC MODE
and PRE REC TIME menu options can be 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, or USER2 SW.
These options can be found in the USER SW screen,
which is accessible from the CAM OPERATION page.
These are the options for PRE REC TIME.
1-15 SEC (for DVCPRO 25M or DV)
1-8 SEC (for DVCPRO HD or 50M):
Specify the duration for which data may be recorded
before either the REC START/STOP button, REC button
on the handle or VTR button at the lens is pressed.

“P-REC” indication when the “PRE REC MODE”
menu option is set to OFF
After recording is stopped, the “P-REC” indication
remains displayed until all video and sound are recorded
on the P2 card, even if the PRE REC MODE menu
option is set to OFF. For details of the [P-REC] display,
refer to [30.INTERVAL REC/PRE RECORDING
indication/ SD memory card remaining free space (page
75)] in [Viewfinder Status Indication Layout].
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 either
the REC START/STOP button, REC button on the
handle or VTR button at the lens 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 either the
REC START/STOP button, REC button on the handle, or
VTR button at the lens is pressed to start a recording.
z
The internal memory does not store video or sound
when a playback or recording review is being performed.
For this reason, no video or sound can be recorded
during such operation.
z
When recording starts, the time code indication (TCG)
may be shown as “HOLD” until the P2 card has been
recognised.
z
During recording of IEEE1394 input or INTERVAL REC
operation, PRE RECORDING is not available.
