At the top are the original film frames, showing a car moving down the
street. Next comes the original 3-2 pulldown. Simple frame memory I/P
conversion results in a motion blur every time fields from different film
frames are combined. (This occurs for two out of every five video
frames—or 40% of the time!) At bottom, full 3-2 reverse conversion, as
featured in Sony's progressive scan DVD players, preserves the
integrity of the original film frames.
