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 50P 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.
•  You can select any of 11 recording frame rates 
ranging from 12 frames per second (fps) to 60 fps. 
See [Video and Recording Formats] (page 45).
•  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.
