Capture Presets Editing
Audio/Video Settings, Capture Presets Editing Window
Note: Whenever a Preset is being copied as the basis of a new preset, always
change the name and description to fit the new preset so users aren’t confused
between it and the original.
Frame Size
—below the name and description are the frame size settings. These can
be changed via the pulldown menu. Selecting a new Aspect Ratio value also
changes the values in the width and height fields.
QuickTime Video Settings
—these settings select a video input source and affect
how it’s processed by Final Cut Pro. The Digitizer pulldown menu selects
whether you want the selected input source to be digitized as 8-bit or 10-bit
uncompressed video as it comes into Io
LD/LA
. The Input pulldown selects the
exact input connector(s) where the panel captures and digitizes video when this
preset is being used. The
Compressor pulldown selects a codec that tells Final
Cut how to process the video; the codec selected should be chosen for
compatibility with the Digitizer setting selected. For example, if your Digitizer
setting is 10-bit Uncompressed, then the Compressor setting should be one of
the 10-bit choices available. The
Quality slider should be set to 100 percent and
the FPS (Frames Per Second) setting should always be set to 29.97. The
Advanced settings button opens a new screen that is redundant and isn’t needed
for Io
LD/LA
usage.
QuickTime Audio Settings
—these settings select an audio input source and affect
how it’s processed by Final Cut Pro. The Device pulldown should be set to Io.
The Input pulldown selects the exact input connector(s) where Io
LD/LA
captures
and digitizes audio. The Rate pulldown selects a sample rate; it should always be
set to 48 kHz for Io systems. By clicking on the Advanced button, a new screen
will be displayed where you can select between 8- and 16-bit sampling—
typically you’ll want to use 16-bit for CD quality sound.
