Loop Recording
When two or more P2 card slots contain cards, this function allows the target P2 card to be switched in order. Even when the free space of a P2 card is used up, this function continues recording while erasing existing data.
To use this function, the menu option LOOP REC MODE must be set to “ON” The option LOOP REC MODE can be found in the <REC FUNCTION> screen on the SYSTEM SETTING page.

Data are recorded by connecting the unrecorded sections on the P2 card (in the sequence of A to B to C). When the remaining recording capacity is less than 30 seconds, A is deleted, and data are record on C up to FULL (remaining memory capacity is 0), and then new data are recorded (D).
Notes
zWhen the loop recording capability is used, each P2 card must have at least one minute of free space.
zDuring loop recording, the P2 CARD ACCESS LEDs for all target P2 cards illuminate in orange. Note that if any of the target P2 card is removed, loop recording stops.
zWhen the menu option LOOP REC MODE is set to ON, the viewfinder and display window both show “LOOP”. However, when only one card is inserted, or when each card has less than one minute of free space, the loop recording capability does not work, even if the option LOOP REC MODE is set to ON. If this is the case, the indication “LOOP” flashes in the viewfinder and on the display window.
zWhen the menu option LOOP REC MODE is set to ON, the P2 card remaining free space indicates the minimum guaranteed recording time. The minimum guaranteed recording time means the guaranteed time or length of recorded data when LOOP REC stops immediately after deleting old data.
zDuring recording of IEEE1394 input or INTERVAL REC operation, LOOP REC is not available.
Terminating the Loop Recording Mode
You can terminate the loop recording mode by either:
zTurning off the POWER switch of
zSetting the menu option LOOP REC MODE to “OFF”.
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
Notes
zWhen 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.

*1 For instance, interval recording is at every 24 frames
since frames are cut off every two frames even if the REC TIME is set to 1 second (= 25 frames) in the 25PN mode of 720P.
