To enable this option in the Deinterlacer MegaCore function, open the Deinterlacer
MegaWizard Plug-In Manager. In the Parameter Settings tab, under the Behavior
parameter, select Motion Adaptive from the Deinterlacing method drop-down
option and select Triple buffering with rate conversion from the Frame buffering
mode drop-down option.
If you are using the Deinterlacer II MegaCore function, in the Parameter Settings tab,
under the Behavior parameter, select Motion Adaptive from the Deinterlace
Algorithm drop-down option.
With the moving “Dial” test sequence, a motion-adaptive interlacer detects the
motion, preventing incoming artifacts that would otherwise appear. The
motion-adaptive interlacer performs a Bob interpolation and operates on a 3x3 kernel
of pixels, therefore has the ability to interpolate along the diagonal and reduce the
staircasing effect. The area is 5,188 LUTs for the Deinterlacer MegaCore function and
3, 696 LUTs for the Deinterlacer II MegaCore function.
