Variable Frame Rate (VFR) Recording Function

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.

Native VFR Recording

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.

Standard VFR Recording (Pull-down Recording)

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.
