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.

- 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.
