41Recording and Playback: Interval RecordingRecording and PlaybackIt is possible to record in intervals of one frame as theshortest length by using the internal memory of the unit.To use this option, open the screen fromthe SYSTEM SETTING page, and set the interval recordingmode, REC TIME, PAUSE TIME and TAKE TOTAL TIME forthe menu option INTERVAL REC MODE. When the settingsare finalized, TOTAL REC TIME needed on the P2 card isautomatically 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 durationspecified under the REC TIME option bypressing either the REC START/STOP buttonor VTR button at the lens.¡Notesy When executing interval recording, data cannot be outputwith IEEE1394. When the 1394 CONTROL is set to“BOTH”, it is also impossible to control external devices.y 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 30PNmodes is selected using the REC FORMAT menu option.)y The shortest recording time, stand-by time, and the setvalue of the cut-off unit frame number* may vary with therecording method as follows.* For instance, interval recording is at every 24 frames sinceframes are cut off every 2 frames even if the REC TIME is set to1 second (=25 frames) in the 25PN mode of 720P.1 Following basic operations of shooting and recordingaccording to [Basic Procedures], lock the camerasecurely.2 Check that “i” is blinking in the display, and that theinterval recording mode is selected.3 Press either REC START/STOP button or VTR button atthe lens.Interval recording starts. Recording automatically stopsafter the specified TAKE TOTAL TIME, and the entirerecording is generated as one clip.“i” starts blinking in the display when the internalrecording mode is selected. “iREC” illuminates afterrecording starts. “iREC” blinks during a pause.The display in the viewfinder is the same as that in thedisplay window.The tally lamp illuminates during recording. If PAUSETIME is set at 2 minutes or longer, the tally lampilluminates at 5-second intervals to indicate that it ispaused. The tally lamp also blinks 3 seconds beforerecording starts.Interval RecordingRecording method Unit framenumber1080i 60i, 50i30P, 25P (Pull down)30PN, 25PN (Native)1 frame24P, 24PA (Pull down) 5 frames24PN (Native) 4 frames720P 60P, 50P30P, 25P (Pull down) 1 frame30PN, 25PN (Native) 2 frames24P (Pull down) 5 frames24PN (Native) 4 framesShooting procedures when INTERVAL REC is ON112233NNt1 t1t2 t2t1 t1t2t1N-1N-1iREC start Time AxisReal-time videoSoundREC TIME(Recording time=t1)PAUSE TIME(Pausing time=t2)TAKE TOTAL TIME(Time necessary for shooting)Content on P2 cardTOTAL REC TIME(Recording time on P2 card)One clip
