from the De-interlacing drop-down list. Select None if de-interlacing is not necessary; Blending for improved image quality
that is not as processor intensive; Adaptive Interpolation performs de-interlacing of the video stream by applying different
filters on the image. This m a y give a b ette r result than M otion Adaptive Inte rpolation in rare cases; Motion Adaptive
Interpolation perfor m s de-interla cin g of the video stream by applying different filters depending on the m otion in different
parts of the image. This will in most case s result in the best image qual ity.
