Adjust onscreen trackers in Motion

The Analyze Motion, Match Move, and Track behaviors use onscreen trackers that you can position and adjust to better analyze an area of pixels (a reference pattern) in a clip.

Adjust the object tracker

  1. Select a tracking behavior in the Layers list in Motion.

  2. In the Behaviors Inspector, make sure the Mode pop-up menu is set to Object.

  3. Do any of the following:

    • Adjust the object tracker in the canvas: Drag a size handle, roundness handle, or rotation handle. To reposition the tracker, drag inside of it.

      To resize the tracker uniformly, press and hold the Shift key while dragging a size handle.

    • Adjust the object tracker from the Behaviors Inspector: Drag the Curvature, Position, Rotation, or Scale control.

    • Automatically identify potential subjects of interest: While pressing and holding the Option key, drag the object tracker in the canvas. As you Option-drag, bounding boxes appear over elements in the clip, and oval shapes appear over faces.

  4. To show or hide the onscreen tracker, do either of the following in the Behaviors Inspector:

    • Show or hide the grid lines: Select or deselect the Show Grid checkbox.

    • Show or hide the entire tracker: Select or deselect the Shape checkbox.

Adjust the point tracker

  1. Select a tracking behavior in the Layers list in Motion.

  2. In the Behaviors Inspector, click the Mode pop-up menu, then choose Point.

    The onscreen point tracker is a crosshair in a circle.

    The default point tracker colors are red (when unselected) and yellow (when selected). If necessary, you can change the color of the tracker.

  3. Do either of the following:

    • Reposition the point tracker in the canvas: Drag the crosshair in the canvas. As you drag, a magnified inset shows the tracker’s position and an info window displays the tracker coordinates.

    • Reposition the point tracker from the Behaviors Inspector: Drag in the Tracker Preview area or move the pointer over a track row (labeled “Track 1,” “Track 2,” and so on), click Show, then drag the Position controls.

  4. To adjust the search size of the point tracker in the Behaviors Inspector, do either of the following:

    • Option-drag left in the Tracker Preview area to reduce the size of the search pattern in the canvas, and Option-drag right to increase the pattern search size.

    • Move the pointer over the parameter row of the track you want to modify, click Show, then drag the Track Size slider.

  5. To remove a point tracker, click Remove in the parameter row of the track.

Move multiple point trackers at the same time

  • In the Motion canvas, drag a selection rectangle over multiple trackers, then drag the selection to a new position.

    Selected point trackers appear yellow.

Turn off onscreen point trackers

In Motion, do one of the following:

  • Control-click a point tracker in the canvas, then choose Hide Selected Tracker.

    If there are multiple point trackers, you can choose to hide the selected point tracker or to hide the other point trackers.

  • In the Behaviors Inspector, deselect the relevant Track checkbox.

    When a point tracker is deselected, it’s not used in the analysis.

Change the color of the onscreen point tracker

  1. In the Behaviors Inspector, move the pointer over the parameter row of the track you want to modify, then click Show.

  2. Adjust the Color controls.
