Advanced Fusion Point Tracking

Tracking in Fusion allows you to attach masks and effects, composite images, or build graphics around moving objects.

It’s simple to get started: Choose a high contrast feature, track it and then use the match movement operation to attach a text to a moving object for example.

In practice we have to deal with additional complications. Tracking points leave the frame, are temporarily occluded or change over time due to rotation or perspective. In those cases we have to update the tracking pattern, re-track (append) or extrapolate (gradient extrapolation).

The point tracker’s match move operation allows us to attach a foreground to a moving background (Foreground over Background). But we can also directly access tracking data through modifiers, manipulate the data, and use angle, scale or position to build more advanced graphics.
