Rotation

Enable to calculate feature rotation.

Scale X

Enable to calculate scale changes in the X-

axis.

Scale Y

Enable to calculate scale changes in the Y-

axis.

Offset Button

The Offset button creates an offset shape from the currently selected shape.

This offset shape can be moved (offset) to a new position in the shot from

where new feature points are calculated. The feature points calculated using

the offset shape are applied to the original shape. You can re-position an

offset shape any number of times in the same shot if required, with any

tracking data calculated applied to the original shape. See Offset Tracking.

Smooth Button

Normally, the DVO Tracker will position the transformed shape (x/y,rotation,

scale) in single pixel increments. The Smooth button will enable sub-pixel

positioning, and cause the track to be re-computed.

This smoothing effect will be visible by switching to the Keyframe Editor tab

and viewing the resultant animation graph.

If you turn the Smooth button off before completion, the smooth

process will stop and any smoothing done will be reset to its

previous state. Once complete, an undo operation will also reset the

entire track path to its pre-smoothed state.

Reset Track Points

These buttons allow you to reset all or some of the key-frames created by the

tracking process.
