First Compact Shoulder camcorder to offer
Native File Recording onto inexpensive solid state media.
JVC announces its latest Compact Shoulder professional camcorder
developed for mainstream production, electronic newsgathering
and cinematography, the GY-HM700. The new camera uniquely
records directly to inexpensive SDHC memory cards in the QuickTime
(.MOV) format for Final Cut Pro, and optionally to SxS
media compatible with Sony's XDCAM EX format.
Recording in the editing system's native format eliminates
the time consuming transfer step and dramatically speeds up
the post-production workflow, a major advancement for JVC
and the industry. Additionally, the GY-HM700 includes several
key technology innovations that result in significantly improved
resolution in the camera's core components: CCD/optical block,
lens, and viewfinder.
"Our new generation of ProHD products brings together
the most highly regarded and proven technologies in the industry,
providing unmatched ownership and operational experience,"
says Craig Yanagi, JVC's national marketing manager for Creation
Products. "With the GY-HM700, JVC has changed the dynamics
of professional video production. Its ergonomic design and
video quality meets or exceeds the performance requirements
of the most demanding broadcast, ENG and cinematography applications.
Combined with fastest shoot-to-edit workflow in the industry,
utilizing low-cost solid-state media, ProHD provides an unprecedented
level of efficiency and economy for today's professional videographer."
Industry's first native support QuickTime file format for
Apple's Final Cut Pro
The GY-HM700 natively records the QuickTime file format used
by Apple for Final Cut Pro. There is no need to convert or
rewrap files prior to editing. Post-production can begin immediately
after shooting. It is even possible to edit directly from
the memory card. Since no transfer or re-encoding takes place,
first generation quality is always maintained.
The GY-HM700 is the industry's first shoulder supported camcorder
to store files on inexpensive SDHC memory cards. The camera
provides 2 memory card slots, for a total of up to 64GB of
on-board storage—enough for more than 6 hours* of continuous
HD recording. The camera automatically begins recording on
the second card when the first card fills up. When the second
card fills up, the camera reverts to recording to the first
card slot, allowing for virtually unlimited recording lengths.
SDHC cards are economical, highly reliable, and make possible
a recording system that consumes up to 20% less power than
tape or HDD based systems. The per-minute cost of SDHC memory
is comparable to video tape. Moreover, SDHC media is the first
practical solid state solution to physical archive.
By attaching the optional KA-MR100 dockable media recorder,
it is possible to record Sony XDCAM EX compatible .MP4 files
onto high-speed SxS memory cards, while at the same time recording
the same .MP4 files to inexpensive SDHC cards. Having two
copies instantaneously available provides more versatility
in the field with the assurance of always having a back-up.
High Resolution Progressive Imaging
The GY-HM700 utilizes three precisely aligned 1/3-inch progressive
scan full HD CCDs. JVC engineers developed a unique 1/3-inch
optical block with Diagonal Offset and a patented exclusive
Adaptive Pixel Correlation Technique that produces resolution
significantly higher than previous JVC models and comparable
to cameras with larger image sensors.
The higher resolution imaging is complemented with a new standard
detachable HD lens by Canon, the KT14x4.4KRSJ. Its superior
MTF provides higher resolution than typical "stock"
lenses and is ideal for full 1920 x 1080 imaging. The GY-HM700's
standard bayonet mount accepts a wide range of optional lenses
available from JVC. Cinematographers will also appreciate
JVC's optional prime lens adapter. The GY-HM700 can flip the
image commonly inverted when prime lenses are used.
JVC's proprietary MPEG2 encoder provides highly efficient
compression at bit rates up to 35Mbps. The GY-HM700 supports
all major HD signal formats including 1920 x 1080, 1440 x
1080 and 1280 x 720.
New High Resolution LCOS Viewfinder
The GY-HM700 is equipped with a new, rugged high resolution
viewfinder based on a new .45-inch 1.22 million pixel Liquid
Crystal on Silicon (LCOS) panel (852 x 480 x 3). This new
all-digital viewfinder displays images with more than 5 times
the resolution of typical color viewfinders. Its sturdy reinforced
die-cast aluminum chassis and LED light source ensure years
of trouble-free operation.
Also provided is a new jumbo size 4.3-inch flip-out LCD monitor
that functions for recording, playback, clip management, and
menu operation. Menu operation is intuitive with a single
disk, outlined by an LED lamp.
Weighing in at a mere 8 lbs. including lens, viewfinder, microphone
and battery, the GY-HM700 can rest comfortably on the right
shoulder to provide stable, steady shots, without causing
the fatigue associated with bulkier cameras.
The GY-HM700 records two channels of uncompressed LPCM 16
bit audio at 48Khz. Levels can be controlled manually, or
automatically using AGC, and an audio meter is provided in
the LCD and viewfinder displays for easy adjustment. Balanced
XLR inputs with phantom power are provided on the camera for
an external microphone and/or wireless receiver, and a shotgun
microphone is provided.
Built-in clip view and management functions, a spot exposure
meter, and JVC's patented Focus Assist round out the GY-HM700's
many on-board features. The camera provides HD/SD SDI, Component,
Composite and simultaneous DV/HDV IEEE-1394 outputs. Optional
JVC remote control units can be connected to the GY-HM700's
6-pin remote connector.
