“It would be easy if delivery of new drivers was merely a PR job–but sadly it’s not. It involves extensive engineering, testing, Q&A to make sure that any new technology that comes to market from AJA is completely reliable.  As the third party PR firm that handles press communication for AJA–we will be sure to put out an announcement as soon as the new drivers become available.”   Karen Raz AJA PR Dept.

UPDATE  “Were it entirely up to us we would have had drivers for the IoHD at the same time as they became available for the cards which was the same day Apple released its new software.  However, given the fact the IoHD is in and of itself a unique device and operates with the computer in a way entirely different from the KONA cards, the building of the drivers is quite different and requires more engineering time.

Please keep an eye on our website for the posting of the drivers.  They should be posted shortly.  For your future reference and just to be sure we always recommend you not update the OS or FCP until such time as the drivers are posted on our website.  This is true for both the IoHD and the cards.”

Well at least Karen and Brian were good enough to reply…so thinking about this at length…With my limited knowledge of electronics I think this unit was built with PRO REZ 4:2:2 in mind then good old Apple introduced PRO REZ 4:4:4, I think AJA are having a hell of a job frigging 4:2:2 up to 4:4:4  via firmware.

I have a solution, meantime give us all the EXPRESS unit on loan…then re-design this box with more HDMI I/O sockets with 3 switches on the front (HDMI-1, 2 & 3), add a PCIe connection (Not FW800) giving us a 75% discount on V2 by sending back V1… JOB DONE !
