Pause On: These two choices determine what happens when the editing application 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).
Software 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.
