AJA Control Panel, Conversion Screen
Conversion Screen Settings
Pause On—these two choices determine what happens when an 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).
3-2 Pulldown Pattern—after format selection, the value selected in this menu is used
whenever you’ve chosen to do conversion from 24 frames-per-second to 30 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 that the conversion will 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 determ ine it for you.
Colorspace—choose from:
Rec 601 – for SD
Rec 709 – for HD
