Upconverting Standard Definition Video

Upconverting a 4 x 3 aspect ratio image in a 16 x 9 frame results in borders (or side
panels
) on the left and right sides of the 4 x 3 image. This type of frame is sometimes
referred to as pillarboxed.

If the aspect ratio of the original and destination formats match, you can simply scale
the original video to the destination size.

4 x 3 anamorphic video is actually a 16 x 9 image squeezed into a 4 x 3 frame, so it can
easily be scaled to fit a high definition sequence.
