In a studio configuration, the GY-HM790 can be hand held, or easily fitted with the KA-790 sled, a sleek and functional housing that supports a studio viewfinder, teleprompter and large lens if desired. JVC's VF-HP790 is an 8.4-inch high resolution LCD viewfinder with a digital interface to the camera.
The GY-HM790 supports all major signal formats including 1920 x 1080, 1440 x 1080, 1280 x 720, and 720 x 480.

|When recording in the 720p 35Mbps mode, the camera can be set to record at a frame rate different than the playback rate. This capability makes it possible to record slow or fast motion when the recording is played back at 24p or 30p.|
In addition to the GY-HM790's standard detachable 14x Canon lens, numerous lens options are available from JVC including the 13xTh13x3.5BRMU wide angle Fujinon zoom lens, a new 17x XT17sx45BRMK1 Fujinon zoom lens, 18x HTs18X4.2BRM Fujinon zoom lens, 20x KT20X5BKRS Canon zoom lens, and adapters that allow ½-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-HM790, greatly expanding production lens options. The camera features an "image flip" function that corrects for the inverted image produced by prime lenses.
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.
The GY-HM790 incorporates JVC's Native File Recording technology that stores video in the ready-to-edit file formats used by Apple's Final Cut Pro™, Adobe Premiere™, and other popular non-linear editing systems. The HD and SD ".mov" files created in the camera can be easily dragged onto Final Cut Pro's or Premiere's timeline or clip bin without conversion or rewrapping, saving time while keeping the recorded material first generation. There is no need to use an intermediate codec.
For users of other NLE systems, including solutions from Avid, Canopus and Vegas, the GY-HM790U supports the MP4 file format which can edited without re-encoding. HDV-compatible M2T files can also be created from these MP4 files using the ProHD Clip Manager. 4:2:2 uncompressed digital video is provided via HD-SDI output for recording onto an external recorder.
For standard definition applications, in addition to .mov format files, the GY-HM790 creates popular type-2 AVI files that imports easily into most current and legacy NLE systems.
*1 Play back compatibility not guaranteed on different types of products due to variation of supported recording mode.
*2 MP4 is the compliant file format used on the XDCAM EX™
*3 SxS is a flash memory card designed for professional video cameras with a high-speed PCI Express interface.
|Unsurpassed Versatility |
Complementing the new high resolution viewfinder is a large LCD flip out monitor that can be used in recording, playback, clip management, and menu operation. The 4.3-inch 800x480 WVGA LCD offers a 16:9 aspect ratio and provides a wide array of monitoring and setup indications. It is specially designed to reduce surface reflections and glare to maintain a clear, visible, bright view during outdoor recording. Menu items are easily selected using user-friendly setting cross keys.
Cross-key control makes menu navigation a breeze. The interface is very intuitive, with up down/left-right buttons on the same control disk. Selections are made by pressing the center of the disk. When in the camera mode, a blue LED lamp outlines the disk. When in the media playback/management mode, the color changes to green. A Red display indicates that the camera is in the USB or IEEE-1394 (slave) mode. (The LED can be turned off with a menu choice.)
Extensive image customization is available. Thanks to the oversize monitor screen, the user see changes to the image as the setting is being made, eliminating guesswork. Individual user settings are stored on an SDHC card and may be restored to any GY-HM790 or GY-HM700 camera.
Detailed information is displayed about each clip including recording format, resolution, and time code start/stop, user bits, and creation date/time. Clips can be protected from accidental deletion or deleted if no longer needed. Damaged clips (due to improper eject, etc.) may be repaired with the "restore file" function. Though no special formatting is required, memory cards can be re-initialized in the GY-HM790 to an empty state even while the other card is recording.
The Quick Review function is available in the record-pause mode and allows the videographer to play back the first 5 seconds or the last 5 seconds of each clip, or the entire clip. After playback, the last image is retained (freeze) until the menu is reactivated. If during Quick Review, the record trigger is pressed, playback stops and recording begins immediately.
For live broadcast applications, or for monitoring, the GY-HM790 provides an uncompressed, 4:2:2 full HD or downconverted SD signal via its HD/SD SDI connector. The signal can come from either the camera or from memory playback. When downconverted, the video may be in either PAL or NTSC depending on the HD mode selected: 60Hz (23.98p, 29.97p, 59.94p/i) = NTSC, 50Hz (25p, 50p/i) = PAL. When 23.98p modes are selected, it will contain Varicam™ flags (720p24 mode only) to facilitate post production. The HD/SD SDI output is via a BNC connector and includes embedded uncompressed audio. It is also possible to output the menus and clip viewer via the HD/SD SDI output.
The IEEE1394 output is via a 4-pin connector and provides HD or HD depending on the mode. The audio output is HDV compliant in HD mode and DV compliant in SD mode.
