![]() ![]() Multiple File Formats for Native Workflows Record HD or SD footage directly in ready-to-edit QuickTime™ MOV files, the native file format of Apple’s Final Cut Pro™. This means that professionals have unprecedented flexibility to meet production standards through a wide range of workflows. MPEG-2 and AVCHD Recording The GY-HM620 supports both the popular MPEG-2 Long GOP 35/25/19Mbps format, widely used by television broadcasters, and the highly efficient AVCHD 24/17Mbps mode, which provides compatibility with a wide range of affordable editing systems. Together with this technology, superior image quality has been realized with 2D DNR processing and compensation circuitry for wide dynamic range. Delivering tremendous processing power on a single chip, the on-board FALCONBRID™ engine processes large amounts of video data at exceptional speeds. Revolutionary FALCONBRID™ Image Processing Engine FALCONBRID™ is JVC’s high-speed processor for advanced video applications. Standard sensitivity of the GY-HM620 is measured at F12 2,000 lux (60Hz) and F13 2,000 lux (50Hz). An ALC mode is also available to boost gain values from +6dB to +24dB. These switch positions can be adjusted to various gain amounts from -6dB to +24dB. A convenient gain switch provides default gain values of -6dB, 0dB, +9dB. LoLux can be assigned to a USER button, and set in the menu to offer +30dB or +36dB of gain. JVC’s exclusive LoLux feature permits shooting in adverse lighting conditions. Minimum illumination is less than 1 lux: 0.15lx (typical)*. Outstanding low light performance The GY-HM620 produces outstanding images in all sorts of lighting environments, including in situations where there’s not much light at all. The built-in Optical Image Stabilizer (OIS) helps to correct lateral and vertical movement of the camera, ensuring that pristine HD images remain sharp and stable. The GY-HM620’s long zoom range means that you can get shots not possible with other cameras its size. Other features include an optical image stabilizer, chromatic aberration correction. ![]() The lens offers F1.6-3.0, a focal range of 29mm-667mm (35mm equivalent) and includes servo zoom, manual focus, and iris rings, along with a four-position (clear, 1/4, 1/16 and 1/64) ND filter. 23x Fujinon Auto Focus Zoom Lens with Manual Functions The GY-HM620 is equipped with a Fujinon wide angle 23x zoom lens that delivers superior low-light performance with brightness at the tele end. Offering an excellent sensitivity of F12 (60Hz) /F13 (50Hz) and a remarkable signal-to-noise ratio, the devices provide superior precision and color reproduction. New High Performance Full HD 1/3-inch CMOS Sensors At the heart of the GY-HM620 are three, newly designed 1/3-inch CMOS sensors, each capable of capturing full HD 1920 x 1080 resolution images. Not only can you produce better quality recordings, but you’ll do it in less time than ever before. Its advanced JVC Falconbrid image processor delivers the highest quality recordings in a variety of popular formats that don’t require time consuming conversion for editing. Equipped with a high quality 23x Fujinon lens and and new full HD 1/3-inch CMOS Sensors, the camera delivers superb sharpness and excellent low-light performance.
