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).
3-2 Pulldown Pattern—after format selection, the value selected in this pulldown is used
whenever you've chosen to do 24 frames-per-second to 30 conversion where extra fields
are added to pad 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.
3-2 Pulldown Offset—select a frame offset value from 0 to 4.
RGB-YUV Conversion: These pulldowns select industry standard color space and gamma
transfer functions for the YUV-RGB conversion, or allow you to direct the KONA card to
automatically determine it for you.
