TYPO…. I meant “HD.”
The AJA I/O connects to your computer via firewire (making it a portable box for mulitple systems) that has many connections. Component, Composite, SDI…IN and OUT. All of them. And XLR in and out…RCA you’ll need adapters.
The Kona LH is a card that installs in the mac, so not so portable. But it is an HD card that sports HD SDI/SDI, Component, Composite IN and OUT…analog and digital. And it works with both HD and SD.
The AJA I/O HD is due very soon, and does all the SD in and out that the original I/O does, but also works with HD. It too connects via firewire (FW800 as opposed to the SD version that is FW400), and sports more connections that you can shake a stick at. (www.aja.com). BUT…it doesn’t do uncompressed HD. It does, however, have an on-board hardware compressor that compresses to ProRes 422, which has the same quality as unocmpressed HD, but much smaller data rate.
And not to leave the competition out, the Decklink Extreme HD has all the connections as the Kona LH, and the Decklink Eclipse also sports many many many options.
Look at them all and decide for yourself.
Just know that Apple and AJA work VERY close together.
