Variable Frame Rate (Vfr) Recording; Native Recording - Panasonic AG-HPX500P Operating Instructions Manual

Variable Frame Rate (VFR) Recording

This camera takes full advantage of P2 card
characteristics by providing frame skipping
(undercranking) recording and high-speed
(overcranking) recording without the use of a frame
rate converter. (The camera must be set to 30PN,
25PN or 24PN to use these functions.) Since the
camera records only the effective frames (native
recording), recording time is 2 to 2.5 times longer than
in the 24P, 30P and 60P modes (25P or 50PN at 50
Hz) (standard recording). Like VARICAM (the AJ-
HDC27 series), it also provides a recording format that
can accommodate the frame rate conversion required
for nonlinear editing. (The camera must be set to 30P,
25P or 24P).
<Note>
Variable frame rate (VFR) recording is available only in
the 720P mode.
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 Variable Frame Rate (VFR) shooting, you
must set the recording frame rate and the recording
format.
• You cannot change the frame rates while recording.
• Variable Frame Rate (VFR) recording is available
only in progressive shooting at 720 vertical lines.
