Antialiasing of Interlaced Video Animation
1. Abstract
The production of computer-generated video presents a
number of difficulties not encountered with motion pie-
tures. Interlaced scanning and the color subcarrier of
NTSC video are responsible for special problems such
as interline flicker, and chroma aliasing. As in motion
pictures, temporal aliasing is also an issue. A renderer
can sample and filter a moving image in an arbitrary
manner and is not constrained to simply imitate the
behavior of a television camera. This paper explores
several different spatiotemporal antialiasing filters and
how they affect the quality of video animation.

In many ways, a motion picture is a simpler representa-
tion of moving images than video. A motion picture is
made up of a sequence of essentially continuous two-
