B. Choosing the Correct Deinterlacer
Figure B–1 through Figure B–3 show some example output from the various
deinterlacer options available. The lowest quality is a simple Bob deinterlacer. The
highest quality is motion adaptive high quality (HQ) setting in the Deinterlacer II
MegaCore function.
To enable this option, open the Deinterlacer MegaWizard Plug-In Manager. In the
Parameter Settings tab, under the Behavior parameter, select Bob Scanline
Interpolation from the Deinterlacing method drop-down option. With this moving
“Dial” test sequence, a Bob deinterlace produces the characteristic staircasing effect on
the edges of these diagonal lines. The area is 454 look-up tables (LUTs).
