Follow Track Constraint

By default the Follow Track constraint is making objects have the same position at a frame as the track has. The motion of this object happens on a single plane defined by the camera and the original position of the object.

Receive tracking data from the scene's Active Clip. If unchecked, an option appears to choose from the other clips.

3D Position

Use the 3D position of the track to parent to.

Undistorted

Parent to the undistorted position of the 2D track.

Frame Method

Defines how the footage is fitted in the camera frame.

Camera(カメラ)

Select the camera to which the motion is parented to (if empty, the active scene camera is used).

Depth Object

If this object is set, constrained objects will be projected onto the surface of this depth object which can be used to create facial makeup visual effects.

Constraint to F-Curve

Creates F-curves for the object that copies the movement caused by the constraint.

Influence(影響)

Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
