Product Overview
Shake 4
Shape-Based Morphing and Warping
The shape-based morphing and warping in Shake 4 can be used for fantastic shape
shifting or seamless corrective e∂ ects. Integrated directly into Shake 4, morphing and
warping shapes use standard spline tools. These tools make it more intuitive to create
and modify an e∂ ect than mesh-based warping tools. Unlike hardware-based warping
tools, Shake 4 uses high-quality software-based rendering for fi ne precision. Trackers
can be applied to shapes to create moving morphs and warps more quickly, and the
high-quality warping engine takes advantage of dual processors.
Shape-based morphing and warping (as opposed to mesh-based approaches) is based
on the concept of using common roto tools to outline areas of an image you want to
distort. Once you outline the interesting areas, you then create “destination shapes”
that depict where you want the original outlines to end up. Although many people
recognize morphing and warping as fantastic visual e∂ ects, morphing and warping
are fundamental as corrective tools used on a regular basis.
AutoAlign
AutoAlign is a unique transform node that uses optical fl ow analysis to combine
multiple source images into a single panorama. Images that overlap either horizontally
or vertically are aligned, warped, and luminance-matched to create a single seamless
output image—all without user intervention.
Unlike similar photographic tools, the AutoAlign node works with both stills and
image sequences. As shown below, you could take three side-by-side shots or an
expanse of action and later transform the shots into a single extremely wide-angle
background plate.
