Note the following about native VFR
recording.
•
Pre-recording, loop recording, interval
recording, one-shot recording, and one-clip
recording are not available.
•
1394 output is not available during
recording and recording standby.
•
Changing Scene Dial position during
recording does not change VFR on and off
position.
•
Sound cannot be recorded.
*1
At this time, no audio is output and
“
A. REC
” is displayed over the audio level
meter. “VFR ON, NO AUDIO RECORDING”
is also displayed when recording starts.
•
The time code is locked to Rec Run.
*1
•
Thumbnail screens are created 1 frame
later than video recorded on a P2 card, but
this is not a malfunction.
•
The screen may be distorted when
changing the FRAME RATE setting.
•
Gain is fixed to 0 dB when set to 4 frames
or less.
Furthermore, AGC, auto iris, auto focus,
and ATW do not function and must be
operated manually.
•
Red, blue, or green points may appear on
the screen when the frame rate is low. This
is not a fault.

when the frame rate is 24 and 30 (25) frames
per second, respectively, audio can also be
recorded. The time code can be set to Free
