7-Mode Gamma for Richer Gradation
Drawing on technologies developed for the VariCam, Panasonic has
equipped the AG-HPX370 series with advanced gamma functions that
address seven different shooting scenarios and enhance your creative
abilities. This includes the Cine-Like Gamma, which produces the
characteristic tone of film recordings.
AG-HPX370 series Gamma Modes
HD NORM: Suitable for standard HD recording
LOW:
Works to flatten out a high contrast scene
SD NORM: Normal setting for SD
HIGH:
Provides more contrast and color gradation
B.PRESS:
Provides more contrast and blacks in low contrast scenes
CINE-LIKE D: The Cine-Like mode shifted to prioritize dynamic range
CINE-LIKE V: The Cine-Like mode shifted to prioritize contrast
20-Step Variable Frame Rate
Like the VariCam, the AG-HPX370 series allows undercranking and
overcranking common in film cameras, to create fast-motion and slow-
motion effects. In 720p mode,* the frame rate can be set to any of
20 steps.
*In 1080 and 480 modes, the frame rate can be set only to 25p, 24p or 30p.
• Normal cinematic shooting
(at 24 fps, 25
fps or 30 fps) refers to the same rate as used in
film cameras. The AG-HPX370 series can record
in 1080/24p (over 60i) or 480/24p (over 60i) mode, as
well as 720/24p mode. 25 fps or 30 fps is the standard frame rates
used in the production of TV commercials, music clips and video
software. The AG-HPX370 series can also record in 1080/25p (over 50i),
1080/30p (over 60i), 576/25p (over 50i) or 480/30p (over 60i) mode, as
well as 720/25p and 720/30p mode.
• Higher-speed shooting
(at over 25 fps*) produces slow-motion effects.
This is especially effective for high-action scenes like car chases or
crashes, or to create a dramatic impact in a scene.
*When the standard speed is 24 fps in 59.94
Hz mode. For a standard speed of 25 fps in 50Hz
mode, anything over 26 fps will be overcranked.
• Lower-speed shooting
(at under 22 fps*) lets you attain a fast-motion
effect. This technique can be combined with a warp-speed effect to give
special emphasis to flowing water, fast-moving clouds, etc.
*When the standard speed is 24 fps in 59.94 Hz mode. For a standard speed of 25 fps in 50 Hz
mode, anything under 24 fps will be undercranked.
Native and Over-50p/60p Modes
• 720p Native Mode
In Native mode, the AG-HPX370 series records images at the frame rate
set in the camera. For example in 24 pN mode, it only records 24 frames
instead of the normal 60 frames*. Using the AG-HPX370 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 of a P2 card.
*In 25 pN mode in 50 Hz system mode, AG-HPX370 series records only 25 frames instead of
the normal 50 frames
• 720p over 50p/60p Mode
This is a mode for recording 50p-converted or 60p-converted video.
For example, in 24p mode, it records 60 frames by applying a 2:3
pulldown. The recording time is the same as in 1080i or 720p mode, but
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
P2 recorder such as AJ-HPM200 or AG-HPG20, DVCPRO HD recorder.
*Only when the recording format is DVCPRO HD. There is no output when the AVC-Intra codec
is used.
*24p = 23.98p, 30p = 29.97p, 60p = 59.94p and 60i = 59.94i
