User Manual

The onscreen controls of a selected
tracker seen in isolation.
It’s worth saying a second time that the handle for moving a tracker’s onscreen control is a tiny
dot at the upper-left corner of the inner pattern box. It’s really easy to miss if you’re new to
Fusion. You must click on this dot to drag the tracker around.
The handle for dragging the tracker
boxes to move them around.
In this example, we’ll drag the onscreen control so the pattern box overlaps a section of the
bridge right over the leftmost support. As we drag the onscreen control, we see a zoomed-in
representation of the part of the image we’re dragging over to help us position the tracker with
greater precision. For this example, the default sizes of the pattern and search box are fine as is.
The zoomed-in preview that helps you
position the pattern box as you drag it.
Using the Tracker’s Inspector Controls to Perform the Analysis
At this point, let’s look at the Tracker node’s controls in the Inspector. There are a lot of controls,
but for this simple example we only care about the main Tracker panel, with the tracking
analysis buttons at the top, the tracking options below those, and the Tracker List underneath
those. The Tracker List also has buttons for adding and deleting trackers; you have the option of
adding multiple trackers that can be analyzed all at once for different workflows, but we don’t
need that for now.
