Recording and Playback: Variable Frame Rate (VFR) Recording Function
This unit can shoot at a lower frame rate (undercrank) or
higher frame rate (overcrank).
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.
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.
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.
