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).
Factory AJA presets are easily identified by “AJA” at the beginning of their name.
Since Capture Presets will be used frequently as you bring media into Io Express, we’ll discuss
the edit screen next.

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 pull-down 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 Express. The
Input pull-down selects the primary format Io Express will use to
capture input video. The Compressor pull-down 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 when capturing uncompressed; for other formats use an appropriate quality
level. Set the
FPS (Frames Per Second) setting to the correct frame rate. The Advanced
settings button opens a new screen providing choices of codec-specific options. For
uncompressed codecs these probably are not unneeded; for other codecs choose the
options desired.
