Recording and Playback: Interval Recording

It is possible to record in intervals of one frame as the
shortest length by using the internal memory of the unit.
To use this option, open the <REC FUNCTION> screen from
the SYSTEM SETTING page, and set the interval recording
mode, REC TIME, PAUSE TIME and TAKE TOTAL TIME for
the menu option INTERVAL REC MODE. When the settings
are finalized, TOTAL REC TIME needed on the P2 card is
automatically calculated and displayed.
The following are the options for INTERVAL REC MODE:
OFF:
No interval recording performed.
ON:
Interval recording performed.
ONE SHOT:
Performs “one-shot” recording for the duration
specified under the REC TIME option by
pressing either the REC START/STOP button
or VTR button at the lens.
Notes
When executing interval recording, data cannot be output
with IEEE1394. When the 1394 CONTROL is set to
“BOTH”, it is also impossible to control external devices.
When you set INTERVAL REC to “ON” or “ONE SHOT”,
VFR is set to “OFF”.
(When an item including any of the 24PN, 25PN or 30PN
modes is selected using the REC FORMAT menu option.)
The shortest recording time, stand-by time, and the set
value of the cut-off unit frame number* may vary with the
recording method as follows.
* For instance, interval recording is at every 24 frames since
frames are cut off every 2 frames even if the REC TIME is set to
1 second (=25 frames) in the 25PN mode of 720P.
1
Following basic operations of shooting and recording
according to [Basic Procedures], lock the camera
securely.
2
Check that “i” is blinking in the display, and that the
interval recording mode is selected.
3
Press either REC START/STOP button or VTR button at
the lens.
Interval recording starts. Recording automatically stops
after the specified TAKE TOTAL TIME, and the entire
recording is generated as one clip.
“i” starts blinking in the display when the internal
recording mode is selected. “iREC” illuminates after
recording starts. “iREC” blinks during a pause.
The display in the viewfinder is the same as that in the
display window.
The tally lamp illuminates during recording. If PAUSE
TIME is set at 2 minutes or longer, the tally lamp
illuminates at 5-second intervals to indicate that it is
paused. The tally lamp also blinks 3 seconds before
recording starts.
