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.

1-8 SEC

(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.

Notes

“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 [29.INTERVAL

REC/PRE RECORDING information display (page 81)].

In addition, this display can be turned off by configuring the

P-REC/i-REC settings. The menu item P-REC/i-REC is found

in the

<VF INDICATOR> screen on the VF page.

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.

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.

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.

When recording starts, the time code indication (TCG) may

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

PRE RECORDING function does not work when recording

SDI input signals and when INTERVAL REC and LOOP REC

functions are working.
