3rd-party applications.
NOTE: This screen is present in the Mac version of AJA Control Panel only and not all
applications support these functions.
Software Conversion
These parameters can affect pulldown and pause behavior. This group of
software conversion parameters apply ONLY when using legacy QuickTime based
applications on Mac OS. These applications include Final Cut Pro 7, VTR Exchange
and AJA TV. Applications like Final Cut Pro X, Premiere Pro, Media Composer and
AJA Control Room, no longer use these legacy QuickTime Components.
3:2 Pulldown Pattern
The value selected from this list 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, etc. Select from:
• 2:3:2:3
• 2:3:3:2
• 2:2:2:4
