back is normal (1
						

							42Recording and Playback: Variable Frame Rate (VFR) Recording Function This way of shooting provides the quick motion effects used, for instance to realize speeding clouds, a person standing 
stationary in the blur of a moving crowd, and kung-fu moves. For example, when the scenes have been shot using the 24P 
recording format for specifying playback frames, the speed of the quick motion effects can be doubled by setting the VFR 
recording frame rate to 12 fps.
This way of shooting provides slow motion effects used in car chases, action scenes, climactic scenes and other dramatic 
moments. For example, if the image is taken with REC FORMAT 24P specifying the playback frame, you can get a slow 
motion effect of x1.25 by setting the recording frame rate to 30fps.
* It is necessary to set the 24P VFR RANGE to “30FRAME”. Images of up to 30 frames will be recorded onto the P2 card at this time, but the 
HD SDI output sequence will not be output properly.
24P VFR RANGE is selected in the  screen on the SYSTEM SETTING page.
ySlow motion effect is not achieved when the SYSTEM MODE is set to “1080-50i” and the REC FORMAT is set to “AVC-I 

						

							43Recording and Playback: Loop Recording
Recording and Playback
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  screen on the SYSTEM 
SETTING page.

						

							44Recording 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.

When INTERVAL REC HOLD is set to “OFF”, the mode 
returns to ordinary recording mode if the POWER switch of 
the unit is turned off.
If INTERVAL REC HOLD is set to “ON”, the interval 
recording mode will not change even if the POWER switch is 
turned off.
After setting the INTERVAL REC mode, follow these steps:
1Following basic operations of shooting and recording 
according to [Basic Procedures], lock the camera 
securely.
2Press either the REC START button or VTR button at 
the lens.
The unit automatically goes into ONE SHOT pause 
mode after the specified REC TIME.
3Performs recording for the duration specified under the 
REC TIME option by pressing either the REC START 
button or VTR button at the lens, and returns to ONE 
SHOT pause mode.
4Press the STOP button.
The video and sound stored in memory are generated 
as one clip.
Press the RET button at the lens to put the unit into REC 
REVIEW mode. ONE SHOT operation continues after the 
REC REVIEW.
Even during ONE SHOT mode, clips will not be generated 
on the P2 card until the STOP button is pressed. Press the 
STOP button, and stop ONE SHOT mode operation.ySet the menu option INTERVAL REC MODE to “OFF”.
When INTERVAL REC HOLD is set to “OFF”, the mode 
returns to ordinary recording mode if the POWER switch of 
the unit is turned off.
If INTERVAL REC HOLD is set to “ON”, the interval 
recording mode will not change even if the POWER switch is 
turned off.

Adjustments and Settings for Recording
For the unit to obtain image signals for each HD format, CCD is switching between interlaced scan and progressive scan 
(reading all pixels).
With combinations of the SYSTEM MODE and CAMERA MODE menu options on the  screen on the 
SYSTEM SETTING page, you can select an video system from among 13 types.
SYSTEM MODE menu option
Allows you to select a combination of system frequency 
(59.94 Hz, 50 Hz, 23.98 Hz and 24 Hz) and signaling 
system (1080i). When a change has been made to the 
SYSTEM MODE option, the viewfinder indicates “TURN 
POWER OFF”. Then, turn the POWER switch of the unit 
off and wait 5 seconds or longer before turning the unit 
on again.
REC FORMAT menu option
Used to select the recording format.
AV C - I  1 0 0
The AVC-Intra100 format is used to record 
video. The native recording format applies to 
the 30PN, 24PN and 25PN modes.
AV C - I  5 0
The AVC-Intra50 format is used to record 
video. The native recording is applied to the 
30PN, 24PN and 25PN modes.
DVCPROHD
The DVCPRO HD format is used to record 
video.
CAMERA MODE menu option
Selecting a shooting mode. For information about the 
behavior for each setting, see [Recording formats and 
output connector signal formats] (page 50).

						

							50Adjustments and Settings for Recording: Multi Format The table below shows the formats used to record signals from the CCD and externally input signals along with the formats for 
signals output from the output connectors.
*1 For 1080/23.98PsF and 1080/24PsF, it is possible to record signals of up to 30 frames on the P2 card if the 24P VFR RANGE is set to 
“30FRAME”. However, since the HD SDI output signal is 23.98PsF or 24PsF, the sequence of the signal will not be maintained correctly 
if it is set above 25 frames during the VFR recording. The output image becomes unnatural, but this is not a malfunction.
24P VFR RANGE is selected in the  screen of the SYSTEM SETTING page.
*2 Recording of audio is only possible when the frame rate is set to the same frame rate as set in the REC FORMAT (24PN: 24 frames, 
30PN: 30 frames, and 25PN: 25 frames). However, recording of audio is not be possible for VFR when the RATE SET AT REC is set to 
“ON”.
