Match moving overview

The Match Move behavior analyzes the movement of a source object, then applies that movement data to a destination object. For example, using the Match Move behavior, you can lock a foreground graphic to the side of a moving bus, “pin” foreground video to a background TV screen, or mask a moving element for color-correction purposes.

To use a Match Move behavior, you need at least two objects in your project: a background or source object and a foreground or destination object. The source object provides movement data based on a tracking analysis of its video or its animation attributes (keyframes or behaviors applied to a shape, for example). The movement from the source object is then applied to the destination object. The destination object can be a shape, text, a particle emitter, and so on. For step-by-step instructions, see Match move an object.

By default, the Match Move behavior applies a single tracker to analyze position data of a reference pattern (a small area of pixels) in a movie clip. However, you can optionally apply an additional tracker to analyze and record position, scale, and rotation (see About two-point tracking). Further, you can apply four trackers (a process known as corner pinning) to analyze and record position, scale, and rotation data of an object with four corners—a TV screen or billboard space on the side of a bus, for example (see Corner pin a foreground object).
