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 1/2”-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
