The GY-HM790 features three 1/3-inch CCDs, which allow a lighter, more compact form factor for better manoeuvrability in the field and more flexibility with robotic camera control systems in the studio. It produces 1920x1080 images and can record in 1080i, 720p, and even SD (576i) for operations that have not yet made the move to HD. The camera records at 35 Mbps (HQ mode/variable bit rate) or 19 Mbps/25 Mbps (SP mode/constant bit rate). Although the camera ships with a Canon 14x zoom lens, it can accommodate a variety of lenses with its 1/3-inch bayonet lens mount.
Adopting the successful tapeless workflow introduced in the GY-HM700 camcorder, the GY-HM790 features a dual card slot design that records to low-cost, non-proprietary SDHC Class 6 or 10 solid-state media cards. JVC’s native file recording technology allows recording in ready-to-edit file formats for Apple Final Cut Pro (.mov) and other major NLE systems (.mp4) that are compatible with Sony XDCAM EX workflow.
ENG features on the GY-HM790 include a 4.3-inch LCD screen and a high-resolution, 1.2 megapixel LCOS viewfinder. Two XLR inputs with phantom power offer uncompressed LPCM audio recording with manual level controls.
