Chapter 3 Recording and playback

3-4 PRE-RECORDING function

By always storing a few seconds’ worth (maximum of 10 seconds) of audio and video data shot by the camera, it is possible to record video and audio signals a number of seconds before recording is actually started by pressing the VTR START button or the VTR button on the lens.

In order for this function to be used, it is necessary to open the <REC FUNCTION> screen from the SYSTEM SETTING page and set the data storage time in the memory using the PRE REC MODE item by performing menu operations.

The PRE REC MODE item settings are described below.

OFF: The PRE-RECORDING function is not activated.

0-10SEC:A value from 0 to 10 seconds is set as the length of time for which the video and audio signals can be recorded before the VTR START button or VTR button on the lens is pressed.

<Notes>

≥The data contained in the storage memory becomes unstable immediately after the power is turned on, immediately after the PRE REC MODE item setting is selected or its set time has been changed, and immediately after playback or rec-review has been performed. Immediately after any of these operations, therefore, the video and audio signals will not be pre-recorded for the duration set when recording is started by pressing the VTR START button or VTR button on the lens.

≥The video data and audio data are not stored in the storage memory while playback or rec-review is being performed. This means that the pre-recording will not include the video and audio signals supplied during a playback or rec-review operation.

≥Bear in mind that when the ZOOM UP function is activated during the time set for pre-recording as a focus assist function in the progressive mode, the zoomed-in image will remain in the memory and end up being recorded on the tape.

≥When recording has been started, the time code (TCG) display may remain in the hold status until it is possible for the time code (TCR) on the tape to be read.

3-5 INTERVAL REC function

This unit enables recording in intervals with a minimum recording time in increments of one frame to be conducted.

In order for this function to be used, it is necessary by performing menu operations to open the <REC FUNCTION> screen from the SYSTEM SETTING page, select the interval 3 recording mode using the INTERVAL REC MODE item, and

set the recording time (REC TIME), interval pause time (PAUSE TIME) and time required for shooting (TOTAL TAKE TIME). Upon completion of the settings, the total shooting time (TOTAL REC TIME) is automatically calculated and displayed.

The INTERVAL REC MODE item settings are described below.

OFF: Interval recording is not performed.

ON: Interval recording is performed.

ONE SHOT:

One-shot interval recording is performed for the time which was selected by the REC TIME setting.

Procedure for shooting in the ON modes of

INTERVAL REC

1 After performing the basic operations for shooting and recording as set forth in “3-2 Basic procedures,” secure the unit in such a way that it will not move.

2 Press the unit’s VTR START button or the VTR button on the lens. Interval recording now starts. When the set TOTAL TAKE TIME has elapsed, recording is ended automatically. As mentioned in “2-7 Display window and its displays,” “i” flashes when the INTERVAL REC mode is selected. As soon as recording starts, “iREC” lights. During rec-pause, “iREC” flashes. Exactly what mode is established in the unit can be ascertained by observing these displays.

The same displays as the ones in the display window also appear inside the viewfinder, and the TALLY lamp lights while recording is underway. Further, when the pause time has been set to 2 minutes or more, the tally lamp blinks at 5 second intervals to inform the operator. Further, when pause time has been set to 2 minutes or more, the tally lamp blinks at 5 second intervals to indicate when recording is paused. Under these conditions, the tally lamp will also flash 3 seconds before recording starts.
