There’s a qualification process that Apple does with gear. It’s very involved, and it’s also up to the manufacturers of the products to send in a sample for Apple to qualify…
You can see the current list of these products (cameras, decks, IO gear etc…) if you click on the Tech Specs at Apple’s FCP product site… it’s a downloadable PDF… if you search Applecare on “Qualification”.. you’ll find lists that date back to earlier versoins of the software too. If your camera/deck or whatever isn’t on the list, asking around this forum helps make determinations on whether or not you should spend time trying to make it work etc… Because it still may even if it’s not on the qualified list of supported devices. Sony’s gear for example almost ALWAYS works… reason is they use the latest specs for deck or camera control at all times… AJA’s products usually work too, but when Apple does an update, sometimes there’s hitches, and AJA will have new drivers posted very fast… AJA and Apple have a wonderful relationship, and probably the best of the different manufacturers of I/O gear… IO was actually thought up by Apple, then when Pinnacle passed on the idea, AJA was all over it… tells you something about Apple’s connection now to AJA.
