Abstract
A method for compositing first and second digital images having different pixel aspect ratios to reduce distortion of image content. The method includes determining a scaling factor from first and second pixel aspect ratios; scaling a first image by the scaling factor; and compositing the first and second images into a composite image. The scaling step may be limited to stretching or squashing the first image in only a horizontal direction. The scaling step may include resampling the first image. In another aspect, the invention features a method for controlling motion along a motion path in a composition having nonsquare pixels. The method includes determining a scaling factor based on the composition pixel aspect ratio; applying the scaling factor to a copy of the motion path; reparameterizing the copy of the motion path to generate a scaled motion mapping; and using the scaled motion mapping to control motion along the motion path. The motion path may define the motion of a layer in the composition.
