Internal focus also makes possible a more efficient light-blocking lens hood. Canon's internal focusing system minimizes "breathing" compared with typical focusing systems. The lens has improved lateral and longitudinal chromatic aberration characteristics and is ideal for full 1920 x 1080 imaging. Its superior MTF provides higher resolution than typical "stock" lenses. High-performance Canon HD lens The GY-HM750 includes a detachable 14x Canon KT14x4.4KRSJ HD lens based on the superb optics found in more expensive HD lenses. This feature offers a fundamental advantage for professionals with time-sensitive SD workflows. Recording in SD provides a time-saving alternative to down-conversion of HD material for SD broadcasts, which is still an industry standard in many countries worldwide. Standard Definition Recording Capability Responding to the needs of the industry, the GY-HM750, in addition to its capability as an HD recorder, offers standard-definition recording for maximum flexibility. This capability makes it possible to record slow or fast motion when the recording is played back at 24p or 30p. Variable Frame Rate Recording (Overcrank, Undercrank) When recording in the 720p 35Mbps mode, the camera can be set to record at a frame rate different than the playback rate. The SP mode records at a constant bit rate of either 19.7Mbps or 25Mbps to ensure compatibility with a wide range of equipment. In the HQ mode, the encoder operates with a variable bit rate average of 35Mbps. MPEG2 long GOP is the most widely accepted broadcast standard compression supported by all popular editing systems and broadcast servers. The result is the pristine picture quality that professional users demand, from a surprisingly compact and lightweight shoulder-mount camcorder. Upgraded 35Mbps MPEG2 Encoder Drawing on its long experience of developing dedicated encoders for the broadcasting industry, JVC has equipped the GY-HM750U with a powerful MPEG2 encoder capable of compressing full 1920 x 1080 HD video at up to 35 Mbps. JVC's advanced ProHD capture technology incorporates a new patent-pending Adaptive Pixel Correlation Technique (APCT), and combined with TRIPLEX Offset Technology delivers exceptional resolving power comparable to cameras with larger image sensors. Performance Advanced Technologies = Higher HD Image Quality The GY-HM750 utilizes three precisely aligned 1/3" progressive scan full HD CCDs-one each for red, green and blue primary colors-and outputs full resolution in both 720p and 1080i/p. Note: Fiber and Multi-core modules specifically designed for the GY-HM790 utilize advanced features of the HM790 and are not compatible with the GY-HM750. This design also provides for future expansion. Modules effectively become part of the camera with no unsightly exposed cables. Modules are installed to the rear panel chassis connector, and are powered directly by the camera. JVC presently offers a DVB-ASI module (KA-AS790G) and an SxS Memory Card recorder (KA-MR100G). Modular Design The GY-HM750 is equipped with a 68-pin chassis connector that allows various modules to be attached to the unit without external cabling. And with its ability to easily interface with various JVC modules for live satellite uplink and HD video feeds, the GY-HM750 becomes a truly multi-purpose capture device, equally adept at shooting breaking news, sports, documentaries, and other on-location events. The camera's full complement of broadcast features also include HD-SDI output, 4:2:2 sampling, and variable data and frame rates. That means instant backups or client copies, making your workflow as efficient as possible (an optional SxS recorder provides further extended capture). MOV formats can also be recorded for legacy SD applications, making the camera tops in its ability to output ready-to-edit files for such NLEs as Final Cut Pro and Adobe Premiere.Īlong with an improved Pre Rec cache function, the GY-HM750 adds a trick of its own: simultaneous recording to both of its SD/SDHC memory slots. More streamlined than its studio-friendly predecessor, the GY-HM750 comes equipped with a Canon 14x zoom and is equally capable of capturing 1080i/p, 720p, and 480i video to native. JVC's modular GY-HM750 Compact Shoulder Camcorder is a professional ENG camera that uses the same 1/3" 3CCD sensor and 68-pin chassis as the GY-HM790.
