Conversion Screen
This screen allows you to select codec options such as whether a pause stops on a full frame
or a single field (jitter compensation) and 24 to 30 fps padding patterns.
AJA Control Panel Conversion Screen
3-2 Pulldown —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.
