AJA Io HD drivers updated

Important fixes and enhancements in the version 6.0 driver

AJA has released version 6.0 drivers for the Io HD, AJA’s external video I/O box and format converter connected using FireWire800.

Version 6.0 adds a bunch of new features:

• Support for true progressive (in addition to PsF) 1080p capture and playback.
• Support for 720p/23.98 and 525i/23.98.
• Stand-alone mode for format conversion with no Mac attached.
• “Plug and Play” on FireWire without needing to reboot the computer.
• Simultaneous component and composite outputs.
• Audio delay controls for better A/V sync.
• Io HD’s LCD can be set to show timecode instead of secondary format.
• Better active output format listings in Io-using applications.

It also fixes a long-standing bug with frame-level metadata in ProRes422 captures: Io HD-captured ProRes now shows up as 10-bit video in Shake (and other apps that look at frame-level metadata), whereas before Shake saw the video as only being 8-bit. (The Io HD’s ProRes has always been 10-bit, but it didn’t look that way to Shake without an intermediate render in FCP.)

I had discovered the 8/10-bit issue back before NAB, and bothered the daylights out of AJA’s long-suffering support folks about it (with a tip of the hat to the unfailingly responsive and polite Rudy Van Kol), so the first thing I did when I saw the V6 driver was download it and test it. I can’t yet vouch for everything on the feature list, but I was able to install the software and upgrade the Io HD’s firmware just now without any problems, and I have verified the 10-bit metadata fix in Shake.

Huzzah, therefore, for AJA and version 6.0 Io HD drivers!
