Padding scales the image to a smaller size while retaining the
output image’s frame size. Unlike cropping, padding does not
remove any of the source image. Instead, padding squeezes or
shrinks the image to force it to fit into a different-sized frame. This
can be useful for transcoding files that are stored with incorrect
pixel aspect ratios, such as widescreen DV files that are
incorrectly appearing in a non-widescreen format. You can also
use the padding controls to shrink an image and deliberately add
black borders around the outside of the image.
