Variable frame rates (VFR)
By taking full advantage of the special characteristics of P2 cards, this unit provides frame skipping
(undercranking) recording and highspeed (overcranking) recording, which are actually movie techniques,
without the use of a frame rate converter. (Either the 30PN or 24PN mode must be set for this.)
Since the camera-recorder records only the effective frames (native recording), recording is possible for
between 2 times and 2.5 times as long compared with recording in the 24P, 30P or 60P mode (standard
recording).
As with Panasonic’s Varicam model (AJ-HDC27 series), this unit also provides a recording format that
allows frame rate conversion using nonlinear editing. (Either the 30P or 24P mode must be set for this.)
24PN mode:
The camera-recorder shoots in the 24 fps native mode. The video signals delivering images at a rate of
24 fps are recorded in 24 frames. The signals are recorded only in the effective frames so recording is
possible for 2.5 times as long.

Before VFR shooting, you must set the recording frame rate and recording format ahead of time.
You cannot change the frame rates while recording.
VFR shooting is possible only in progressive-shooting mode with 720 vertical lines.
You can select any of 20 recording frame rates ranging from 12 frames per second (fps) to 60 fps.

There may be slight discrepancies between the recording frame rate displayed and the frame rate at which
the images are actually recorded. Refer to the table below.
