JVC has announced a new addition to its ProHD line of camcorders and will be showing it off at the forthcoming NAB 2010 show in Las Vegas. Capable of shooting in high definition 1080p, the GY-HM790 ships with a 14x Canon HD lens, records to SDHC via dual slots and benefits from a host of modular possibilities.

Aimed squarely at the shoulders (and purses) of professional electronic news gathering broadcasters and following on from GY-HM700 introduced last year, the new addition to JVC's ProHD line also features three precisely aligned 1/3-inch progressive scan CCDs, one each for red, green and blue processing. The GY-HM790 shoots in full 1080p, 1080i, 720p and 480i, has Focus Assist and extensive image customization modes.

Like its predecessor, the new addition records to Class 6 or 10 SDHC flash memory cards via hot swappable dual slots and in HQ mode will record at 35 Mbps and in SP at 19Mbps/25 Mbps. It also features a widescreen 4.3-inch 800 x 480 LCD display and a high-resolution 0.45in 852 x 480 x 3 Liquid Crystal on Silicon 1.2 megapixel viewfinder. The camcorder also ships with a microphone and Canon HD KT14x4.4KRSJ 32 to 448mm equivalent 14x zoom lens, with other lenses possible via a 1/3-inch bayonet lens mount.

The GY-HM790 also benefits from applying the patented Adaptive Pixel Correlation Technique (where the blue pixel sensor array is shifted by half a pixel horizontally and the red pixel array by half a pixel vertically with both being referenced to the green array) which is said to achieve "a remarkable improvement in image texture and resolving power in the 1080i/p modes" and "produces resolution comparable to cameras with larger image sensors".

JVC claims that its new camcorder offers the world's fastest shoot-to-edit workflow, with output being recorded as MP4 or MOV files. The studio adapter sled has been redesigned to incorporate a modular approach to multicore or fiber connectivity for cleaner studio integration and there's a HD/SD-SDI port for uncompressed 4:2:2 full HD signal for live monitoring.

Other studio options include high resolution 8.4in studio viewfinder, 26-pin multicore module and local/fiber remote and a FireWire port also allows painless external backup. There are two XLR inputs with manual level control and phantom power for uncompressed 16-bit/48kHz linear pulse code modulated audio recording.

The GY-HM790 ProHD camcorder will be available this summer for a MSRP starting price of US$11,995, including the Canon 14x HD ENG lens and microphone. There will be numerous modular accessories and add-ons available too. For a pre-release preview, it will be on display at NAB 2010 in Las Vegas from April 12-15.
