Io Express Installation and Operation Manual — Using The IO Express
Codec Screen Settings
24-30 FPS Conversion —the value selected in this pulldown is used whenever, due to format
selection, you’ve chosen to do 24 frames-per-second to 30 conversion where extra fields
will be added to pad the existing ones. Depending on video content, selection of different
field patterns may be useful in reducing jitter due to the content of adjacent fields. The
numbers in the pattern choices specify the frequency with which inserted fields will be
repeated. For example, “2:3:2:3” means duplicate a field twice, then the next field three
times, then the next twice, and then back to three times.

Video Out, Pause On —these two choices determine what happens when Final Cut Pro is
paused in stop mode:
Full Frame: both fields are displayed resulting in some jitter while paused.
Single Field: a single field is displayed, showing no flicker (useful when color
correcting or whenever the flickering would be a distraction).
Timecode Screen
The timecode screen is used too look at incoming timecode from any source. In Final Cut Pro,
timecode always comes from RS-422. In other applications (such as VTR Xchange), timecode can
come from any source and this is where you select that source.
Note: SMPTE 12M-2 is the updated name and specification for what was RP-188.
