Io HD Installation and Operation Manual — Easy Setups for Typical Uses
QuickTime Audio Settings—these settings select an audio input source and affect
how it's processed by Final Cut Pro. The Device pull-down should be set to Io
HD. The Input pull-down selects that Io HD will be used for capturing audio-it
does not select the specific inputs. For specific audio input selection use the AJA
Control Panel application. The Rate pull-down selects a sample rate; it should
always be set to 48 kHz for Io HD. By clicking on the Advanced button, a new
screen will be displayed where you can select between 8- and 16-bit sampling-AJA
recommends 16-bit for optimum sound quality. (This has nothing to do with
input format, as Io HD supports 24-bit embedded HD audio, 20-bit SD
embedded audio, and 24-bit AES audio.)
The Device Control Presets Window
Audio/Video Settings, Device Control Presets Window
This window selects machine control parameters for an attached VTR. Your choice
here tells Final Cut that Io HD is handling the machine control parameters for the
VTR attached to Io HD. The information on the right window pane describes the
current machine control settings and parameters for the VTR attached. For Io HD
presets this means the VTR attached at the RS422 port on Io HD. For non-Io HD
presets, this means camcorder/VTRs attached directly at the FireWire port or via
some other interface.
If you select a preset you can edit it (click the Edit button) or copy and rename it as
another (click Duplicate). The only exceptions to this are those presets marked with a
lock icon; those can be duplicated, but when you try to edit one the system reports
they’re locked and can only be copied (it will create the copy for you when you try to
edit).
When editing a Device Control preset you can change the following:
