Aspect Ratio

The Aspect Ratio parameter allows horizontal or vertical image compression from full
image size to a thin line (1-4 pixels). The Aspect Ratio function compensates for dissimilar
aspect ratios encountered in various video formats. For example, a movie created with a
16:9 aspect ratio can be changed to a 4:3 aspect ratio. DMX values from 0 to 128 squeeze
the image horizontally, and DMX values greater than 128 compress the image vertically.
