Working with the Tracker/Stabilizer Controls (PB only)


    The Tracker/Stabilizer is a panel added to the Layer window once you select the Tracker/Stabilizer controls from the Layer window menu. The window displays the layer you selected to track. To specify an area for tracking, set a feature region, a search region, and a track point in the layer shown. The tracker tracks from the location of the current-time indicator. If the current-time indicator is outside the visible range of a trimmed clip, it tracks from the beginning to the end of the clip. If the current-time indicator is within the visible range of a clip, it tracks from the current-time indicator to the end of the visible range.

    Tracker/Stabilizer controls

    Controls for the Tracker/Stabilizer are described below:

    A. Image area

    B. Tracking regions

    Specifies the search region, feature region, and track point you are tracking. (See Defining tracking regions (PB only).)

    Select whether you want to track or stabilize the image or track the image using either the affine corner pin or perspective corner pin options.

    D. Analyze button

    E. Tracking coordinates

    The first set of numbers in parentheses indicates the layer coordinates of the corners of the feature region. The second set of numbers in parentheses indicates the x and y coordinates of the track point. The number of coordinate groups listed here depends on the tracking type you choose. For example, if you choose Perspective Corner Pinning, then four groups of coordinates display, each group representing a particular feature region and track point.
