This unit can shoot at a lower frame rate (undercrank) or
higher frame rate (overcrank) in the 720P mode. The native
(PN) recording mode or standard (OVER) recording can be
selected.
1
Open the <SYSTEM MODE> screen from the SYSTEM
SETTING page using the menu.
Set SYSTEM MODE to “720-59.94P (60P/50P)”, REC
FORMAT to “AVC-I 100/24PN”, and VFR to “ON”.
Set FRAME RATE suitable for desired way of shooting.
Any frame from 1 (1P) to 60 (60P) can be selected.
2
Press the REC START/STOP button to begin recording
in the VFR mode.
It is possible to select a combination of AVC-I 100, AVC-I 50,
DVCPROHD, 30P, 25P and 24P as recording formats. For
more details, refer to [Recording formats and output
connector signal formats] (page 47) and [SYSTEM
SETTING] (page 165).
Notes
When SYSTEM MODE is set to “720-59.94P”, setting
REC FORMAT to “DVCPROHD/30PN”, “AVC-I 100/30PN”
or “AVC-I 50/30PN” results in operation at DVCPROHD/
29.97PN, AVC-I 100/29.97PN or AVC-I 50/29.97PN
respectively. Setting REC FORMAT to “DVCPROHD/
24PN” or “AVC-I 50/24PN” results in operation at
DVCPROHD/23.98PN or AVC-I 50/23.98PN.
Similarly, when SYSTEM MODE is set to “720-60P”,
setting REC FORMAT to “DVCPROHD/24PN”, “AVC-I
100/24PN” or “AVC-I 50/24PN” results in operation at
DVCPROHD/24PN, AVC-I 100/24PN or AVC-I 50/24PN
respectively.
Note the following when native recording with VFR.
– It is not possible to switch between P2 cards.
– It is not possible to use PRE RECORDING, LOOP REC,
INTERVAL REC and proxy recording.
– There is no 1394 output when recording or waiting to
record.
– During recording, it is not possible to switch VFR “ON”/
“OFF”.
– Audio is not recorded.
– The time code is fixed by the Rec run.
– Thumbnail screens may be produced one frame later
than in the video recorded to the P2 card. It should be
noted that this does not indicate a fault.
1
Open the <SYSTEM MODE> screen from the SYSTEM
SETTING page using the menu.
Set SYSTEM MODE to “720-59.94P (50P)”, REC
FORMAT to “AVC-I 100/60P”, and VFR to “ON”.
Set FRAME RATE suitable for desired way of shooting.
Any frame from 1 (1P) to 60 (60P) can be selected.
2
Press the REC START/STOP button to begin recording
in the VFR mode (OVER 60P).
It is possible to select a combination of AVC-I 100, AVC-I 50,
DVCPROHD, 60P and 50P as recording formats. For more
details, refer to [Recording formats and output connector
signal formats] (page 47) and [SYSTEM SETTING]
(page 165).
Recording a fast-moving subject with the frame rate set to a
low value using the 60P (or 50P) recording format produces
images which can be played back to achieve a flow effect.
Notes
When SYSTEM MODE is set to “720-59.94P”, setting
REC FORMAT to “DVCPROHD/60P”, “AVC-I 100/60P” or
“AVC-I 50/60P” results in operation at DVCPROHD/
59.94P, AVC-I 100/59.94P or AVC-I 50/59.94P
respectively. Setting REC FORMAT to “DVCPROHD/
24PN” or “AVC-I 50/24PN” results in operation at
DVCPROHD/23.98PN or AVC-I 50/23.98PN.
When active frames are extracted using the frame
converter to perform overcrank or undercrank recording, it
is not possible to play back audio.
Note the following for standard VFR recording.
– It is not possible to switch between P2 cards.
– It is possible to combine standard VFR recording with
PRE RECORDING, LOOP REC, INTERVAL REC or
proxy recording.
– There is 1394 output when recording or waiting to
record.
– During recording, it is not possible to switch VFR “ON”/
“OFF”.
– Audio is recorded.
