Shooting Performance
A Host of Features and Functions, Including a Variable Frame Rate Function for Cine-Like Video Production
Variable Frame Rate
In 720p mode,* the frame rate can be set from the conventional
24p/30p to any of 11 steps between 12p and 60p (or 50p).
Like the VariCam, the AG-HPX500 series allows undercranking and
overcranking common in film cameras, to create fast-motion and
slow-motion effects.
* In 1080 and 480 modes, the frame rate is fixed at 24p/30p (25p in the 50-Hz mode).
Higher-rate shooting produces a
slow-motion effect.
This is especially effective for high-
action scenes like car chases or
crashes, or for scenes to create
dramatic impact.
Lower-rate shooting creates a
fast-motion effect.
This technique can be combined with
a Slow Shutter Speed to emphasize
movements, such as flowing water or
fast-moving clouds.
Native and Over-60p (50p) Modes
•720p Native Mode: The AG-HPX500 series records images at the
frame rate set in the camera. Using the AG-HPX500 series to play
back the recording at the normal rate, you can preview the speed
effect right on the spot, without using a frame rate converter.
Native mode also extends the recording time.
•720p over 60p (or 50p) Mode: The unit can output a DVCPRO HD
stream from the IEEE 1394 connector as it records. This lets you
produce a backup copy using a connected external hard disk
recorder, such as the Panasonic AJ-HD1400 DVCPRO HD
recorder or AG-HPG20 P2 portable recorder.

1080/480 24p Advance Mode
When recording in 1080/24p or 480/24p at 60 Hz, the AG-HPX500
series lets you select 24pA (Advance) mode. In this mode, it
performs 60i conversion using 2:3:3:2 pulldown, which maintains
higher image quality than ordinary 24p (2:3 pulldown) in nonlinear
editing*. In 30p and 25p recording (at 50 Hz), the AG-HPX500 series
uses 2:2 pulldown.
