‌Automatic Tracking

 Open the lazysue.avi shot, using the default settings.

 On the Solver panel, set the camera’s solving mode to Disabled.

 On the Shot menu, select Add Moving Object. You will see the object at the origin as a diamond-shaped null object.

 Switch to the Roto Masking panel, with the camera viewport selected.

 Scrub through the shot to familiarize yourself with it, then rewind back to the beginning.

 Click the create-spline (magic wand) button on the Roto panel.

 Click roughly in the center of the image to establish the center point.

 Click counterclockwise about the moving region of the shot, inset somewhat from the stationary portion of the cabinetry and inset from the bottom edge of the tray. Right- click after the last point. [The shape is shown below.]

 Click the create-spline (magic wand) button again to turn it off.

 Double-click the vertices as necessary to change them to corners.

 In the spline list on the Roto panel, select Spline1 and hit the delete key.

 On the object setting underneath the spline list, change the object setting from Garbage to Object01. Your screen should look something like this:

 Go to the Feature Panel .

 Change the Motion Profile to Gentle Motion.

 Hit Blips all frames.

 Hit Peel All.

 Go to the end of the shot.

 Verify that the five dots on the flat floor of the lazy susan have associated trackers: a green diamond on them.

 If you need to add a tracker to a tracking mark, turn on the Peel button on the Feature panel. Scrub around to locate a long track on each untracked spot, then click on the small blip to convert it to a tracker. Turn off Peel mode when you are done.

 Switch to the Coordinate System Panel.

 Go to frame 65.

 Change the tracker on the “floor” that is closest to the central axis to be the origin.

 Set the front center floor tracker to be a Lock Point, locked to 10,0,0.

 Set the front right tracker to XY Plane (or XZ plane for a Y-Up axis mode).

 Switch to the Solver Panel.

 Make sure the Constrain checkbox is off.

 Hit Go!.

 Go to the After Tracking section, below.
