FieldsKit for Mac

From RE:Vision Effects:

FieldsKit is a set of plug-ins providing smarter deinterlacing and more workflow options for interlacing and pulldown.

At the heart of FieldsKit is its Deinterlacer, which deinterlaces video imagery with superior results. Using proprietary field reconstruction and adaptive motion techniques, ReelSmart Deinterlacer can build full frames from fields that are of much higher quality than the standard approaches available in most effects and video editing applications. And because ReelSmart Deinterlacer builds better frames, you'll often see better results when used with other RE:Vision Effects products such as ReelSmart Twixtor and ReelSmart Motion Blur. ReelSmart FieldsKit works in programs that support After Effects plug-ins such as After Effects, Final Cut Pro, Premiere Pro, Boris Red, Commotion and Combustion.
