JVC GY-HM700 Brochure & Specs page 2

Performance
High Resolution with three 1/3-inch
Progressive CCDs
The GY-HM700 utilizes three precisely aligned 1/3-inch
progressive scan full HD CCDs—one each for red, green and blue
primary color. JVC engineers have developed a unique 1/3-inch
optical block with Diagonal Offset and a patented exclusive
Adaptive Pixel Correlation Technique that produces resolution
comparable to cameras with larger image sensors.
New high performance Canon HD lens
The GY-HM700U includes a detachable 14x Canon KT14x4.4KRSJ
HD lens based on the superb optics found in more expensive HD
lenses. Its supe-
rior MTF pro-
vides higher
resolution than
typical "stock"
lenses. The lens
has improved
lateral and longi-
tudinal chromatic
aberration characteristics and is ideal for full 1920 x 1080 imag-
ing. Canon's internal focusing system minimizes "breathing" com-
pared with typical focusing systems. Internal focus also makes pos-
sible a more efficient light blocking lens hood. ENG shooters
will be pleased with its wider angle (20% wider than the current
16x 'stock' lens) and consistent brightness from 4.4mm (wide) to
62mm (telephoto) with no F-drop. Operation is the same as with all
professional lenses, with mechanical control of focus, and servo or
manual control of zoom and aperture.
In addition to the GY-HM700's standard detachable 14x Canon
lens, numerous lens options are available from JVC including a 13x
(3.5 mm) wide Fujinon zoom lens, 17x Fujinon zoom lens, 18x
Fujinon zoom lens, 20x Canon zoom lens, and adapters that allow
2
1/ "-in and 2/3" bayonet mount lenses to be used. Add the HZ-
CA13U film lens mount adapter to the 1/3" bayonet mount, to
enable mounting of 16mm film camera lenses to the GY-HM700,
greatly expanding production lens options. The camera features an
"image flip" function that corrects for the inverted image produced
by prime lenses.
Secure Digital High
Capacity (SDHC)
memory card recording
The GY-HM700 records on widely
available SDHC Class 6 memory cards,
presently available in capacities up to
32GB. 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 record-
ing on the second card when the first card fills up. When the second
card fills up, the camera will revert to recording to the first card
slot, allowing for virtually unlimited recording lengths. Being able
to quickly switch cards with dual slots is invaluable in a breaking
news situation where a producer may wish to begin editing while
the shooter is still capturing footage.
*When recording in 19Mbps mode
Separate flip open covers protect card slots from dust, moisture
and open separately for each card. If a cover is opened while the
card is being recorded on, a warning message is displayed on the
VF/LCD.
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 professional video tape. Moreover, SDHC media is
the first practical solid state solution to physical archive.
Native File Recording
The GY-HM700 incorporates JVC's Native File Recording tech-
nology that stores video in the ready-to-edit file format used by
Apple's Final Cut Pro™ non-linear editing system. The ".mov" files
created in the camera can be easily dragged onto the NLE timeline
without conversion or rewrapping, saving time while keeping the
recorded material first generation. There is no need to use an inter-
mediate codec.
Optional SxS Media Recorder
By attaching the optional SxS media recorder, the GY-HM700
will record in the .MP4 format used by Sony's XDCAM EX™ onto
high speed SxS memory cards. This compact
recorder attaches directly to the GY-HM700
without an adapter, essentially becoming part of
the camera. Simultaneous recording to SDHC and
SxS memory is also possible, providing instant
backup or archival recordings. The compact
media recorder provides status information on its
built-in LCD screen as well as on the camera's
viewfinder. Recorded video on the SxS cards can
be played back on the camera's LCD monitor or
viewfinder.
Pre Rec (Retro Cache) Start Mode—
No more missed shots!
In this mode, the GY-HM700 continually records a few seconds
in cache memory. When the trigger is pressed, the live signal is
appended to the cache recording, giving the shooter a "head start"
in getting the shot. This feature is invaluable in capturing breaking
events when the shot would be lost before a traditional camera
could begin recording. In the 60Hz modes, the cache time is 2.9
