User Manual

A new coordinate control is added to the Polyline mask controls for each published point,
named Point 0, Point 1, and so on.
The Publish Points controls in the Inspector.
The onscreen control indicates published points on the polyline by drawing that control point
much larger. Once a published point is created, it can be connected to a tracker, path,
expression, or modifier by right-clicking on this control and selecting the desired option from
the point’s contextual menu.
The published point in the viewer.
Using “Publish to Path” to Preserve Animation
When a point is published, any animation already applied to that point is removed. However, if
you need to keep the animation, you can use the “Publish to Path” option. This Polyline
contextual menu option publishes the selected points and converts their existing animation to a
path. You can also use the Publish to Path button in the Polyline toolbar.
Using “Follow Published Points” to Add Points
There are times when you will need to have control points that lie between two other published
points follow the motion of the published points, while still maintaining their relative offset and
shape. For this reason, points in a Polyline mask can be set to “Follow Published Points” using
the Polyline’s contextual menu.
When a point of an effect mask is set to follow points, the point will be drawn as a diamond
shape rather than a small box.
A control point set to Follow Published Points.
When this mode is enabled, the new “following” control points will maintain their position
relative to the motion of any published points in the mask, while attempting to maintain the
shape of that segment of the mask. Unlike published points, the position of the following points
can still be animated to allow for morphing of that segment’s shape over time.
