Track window
 
 
 

The Track window contains two separate panes; each pane reacts in synchronization with the other, and shows the time variable elements that MatchMover can manipulate within your project.

Scroll through the Track View, the Graph Editor, and the Track Status View by clicking on the tabs at the bottom of the window, just above the Time line. See User Interface overview.

Click close the Track window. To restore the view, select Window > Track Window.

The Track View

The Track View is used mainly for supervised 2D tracking. See Supervised 2D tracking. The left pane is a sub section of the Project window showing the elements contained in your project in relation to time. See Project window. Within the right pane of the Track View, symbols are used to give a graphic representation of the elements and their state.

The shape of a point indicates whether the point is a key point or a computed point, and the type of tracking generated. See Editing a key point type.

Navigation in the Track View

The horizontal zoom is available by pressing Ctrl+Alt+click and you can fit the entire sequence if possible (one frame has a one pixel minimum width). Just do it by selecting View > Fit To Viewport ("=" is the default shortcut).

Click a track in the Project window and select Sequence > Track Begin or End (or press Ctrl+Shift+up or down) to move to the beginning or the end of a track. Panning in this view is done in the same way as any other view (using Alt+mouse drag), or just by using the horizontal slider.

Track View folders

The right pane is divided into several rows, each one corresponding to an item in the left pane tree view. If an item in the tree view is selected, its corresponding row in the right pane is surrounded by a colored rectangle.

  • The Image Sequences folder contains all the footage. A blue colored bar in the right pane indicates which frames correspond to each sequence.
  • Colored bars for each track in the Point Tracks folder indicate the tracking status and quality according to the Quality Thresholds set in the User Preferences window. See About key points.
    Color Tracking Quality

    None

    Not tracked

    Red

    Poor

    Yellow

    Fair

    Green

    Good

    Hard tracks (manual tracks) are defined by a circle with a cross.

    Soft tracks (automatic tracks) are defined by a cross.

    See also Creating a new track for a definition of the symbols used for the track reconstructuon status.

  • The Camera folder contains the project’s cameras and constraints. A blue colored bar in the Track View indicates that the camera belongs to the current image sequence.
  • For constraints, a small colored line just above the constraint’s colored bar indicates the type of constraint.
    Color Constraint Type

    Light gray

    Unknown

    Dark gray

    Initialized

    Black

    Fixed

    If the constraint is disabled, the bar is hatched.

The Graph Editor

The Graph Editor displays a graphical representation of computed camera parameters as well as providing options to edit the results. Depending on the type of camera motion (hand-held, stabilized, motion-controlled) and the quality of the 2D tracks, it may be useful to smooth some or all of the computed camera parameters. Smoothing can be done by hand, or by using a post filter. See Filtering the results.

The Track Status View

The Track Status View provides read-only information on the computation of track points.

Use the Track Status View to survey the quality of pixel residuals for each track.

Click to close the Track Status View.

To restore the view, select Window > Track View.

To fit the graph to the viewport, select Graph > Fit or right-click in the Track Status View and select Fit from the pop-up menu.
