Panasonic AG-HPX370 manual Cine-like Functions, Mode Gamma for Richer Gradation

Cine-like Functions

The gamma, variable frame rate and other advanced functions let you capture images with a cinema-like feel, expanding your creative and expressive possibilities.

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

HD NORM Mode CINE-LIKE D Mode

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
