AJA Ships Kona-HD

High-def capture and editing board supports Mac OS X By Dave Nagel
AJA Video Systems today shipped its Kona-HD high-definition capture and board. The PCI-based Kona-HD offers 10-bit uncompressed HD capture and supports applications that run on QuickTime, such as Apple Final Cut Pro and Adobe After Effects. The Kona-HD is available only for Mac OS X.

Kona-HD supports most HDTV formats, including 1080i50/59.94/60 and 1080psf23.98/24. AT 10-bit color depth, the board requires a 64-bit, 66 MHz PCI slot, such as those found on Apple's Xserve. But it also supports 8-bit HD formats on standard 33 MHz PCI configurations, such as those found in Mac desktop systems.

Kona-HD also includes six channels of AES I/O at 20- or 24-bit and 48 kHz or 96 kHz. The inputs include hardware sample-rate converters for the connection of non-sync or off-speed digital audio. It also features Genlock for synchronization to an external reference.

The Kona-HD board is built around BlackMagic Design's drivers, as is AJA's previously released Kona-SD standard-def board. It requires a Macintosh running Mac OS X 10.2.1 or later and QuickTime 6 or later. It also requires a disk system capable of 200 MB per second sustained transfer. Pricing varies by distributor.
