Variable Frame Rate (VFR) Recording Function

This unit can shoot at a lower frame rate (undercrank) or higher frame rate (overcrank).

For native VFR recording (1080/23.98PsF (24PsF))

1 Open the <SYSTEM MODE> screen from the SYSTEM SETTING page using the menu.

Set SYSTEM MODE to “1080-23.98PsF (24PsF)”, REC FORMAT to “AVC-I 100 (50)/24PN”, and VFR to “ON”. Set FRAME RATE suitable for desired way of shooting. It is possible to select a frame rate of 1 to 24 if “24FRAME” is selected for the 24P VFR RANGE, and 1 to 30 if “30FRAME” is selected.

2 Press the REC START button to begin recording in the VFR mode.

Notes

When you set the 24P VFR RANGE to “30FRAME” and FRAME RATE to “25-30FRAME”, output image becomes unnatural because the 24PsF sequence cannot be maintained correctly for the HD SDI A · B image signal.

Recording of audio is only possible when the frame rate is set to 24 frames.

For native VFR recording (1080/59.94i (50i))

1 Open the <SYSTEM MODE> screen from the SYSTEM SETTING page using the menu.

Set SYSTEM MODE to “1080-59.94i (50i)”, REC FORMAT to “AVC-I 100 (50)/24PN (25P)” or “AVC-I 100 (50)/30PN”, and VFR to “ON”.

Set FRAME RATE suitable for desired way of shooting. It is possible to select from 1 to 30 (25) frames as a frame rate.

2 Press the REC START button to begin recording in the VFR mode.

Note

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 25P: 25 frames).

When it is set to other frame rates, audio meter in the display window or viewfinder of the unit will move, but it will not be recorded to the P2 card since embedded audio is superimposed on the HD SDI signal.

During recording native VFR - general notes

It is not possible to switch between P2 cards.

During recording, it is not possible to switch VFR “ON”/ “OFF”.

The time code is fixed by the Rec run.

It is possible to combine standard VFR recording with PRE RECORDING, LOOP REC, INTERVAL REC or proxy recording.

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.

Since the embedded audio is superimposed into the HD SDI signal, even if the VFR is set to “ON” in the VFR, it may not be recorded onto the P2 card depending on other menu setting, even if the audio level meter in the display window or viewfinder of the unit is showing a move.

It takes about 10 seconds to be able to record VFR after turning the power ON.
