Io HD Installation and Operation Manual — Easy Setups for Typical Uses
Note: The AJA Io HD was specifically designed to work with the Apple ProRes 422
and ProRes 422 HQ codecs via its internal hardware. Other HD codecs can only
be used with the AJA Io HD via software encoding/decoding. The AJA Io HD
can be used to capture to DVCProHD compression when used in combination
with the MacPro series of Apple desktop computers; these computers provide
sufficient processing power to software encode to DVCProHD compression in
realtime. MacBook Pro computers with attached SATA or FW800 drives and
2GB of memory are also able to capture and playback DVCProHD material in
1080 and 720 formats. The amount of Dynamic RT available on these laptop
computers will not be as much as on a MacPro desktop system. Uncompressed
10-bit 4:2:2 and Uncompressed 8-bit 4:2:2 QuickTime playback is only
supported when using MacPro desktop computers along with the AJA Io HD. An
adequate disk array for uncompressed HD playback is also required.
Audio/Video
Settings Menu
The Audio/Video Settings menu in Final Cut Pro contains a series of tabbed windows
where you define the presets in specific categories such as A/V devices or in what
format media is captured. When you open the Audio/Video Settings window, it shows
a summary of the currently selected Easy Setup.
Other tabbed windows are available with greater details about each category. On the
initial summary window you can see the selected presets for the Easy Setup as well as
change specific presets.
The presets you can change on the Summary window are:
Sequence Preset—select one of these as the editing timebase for new sequences. If
you make a change to Sequence Presets, the change will only take effect on any
new sequences you create—currently active sequences will not see the change.
Capture Preset—select one of these to set the incoming source format you’ll be
capturing. Ideally select the maximum quality format you’ll be using for most of
the material so there will be no need to re-render later as clips are added from the
bin to the sequence.
Device Control Preset—select the AJA Video Io HD device (NTSC or PAL as
desired). This tells Final Cut that the Io HD will control the VTR attached to Io
HD.
A/V Devices (Audio and Video Playback)—select the Io HD as video and audio
playback devices for Final Cut and the format to be output.
