Chapter 10 Using Spline Media
542
Understanding Path Controls
A path is an object that uses a curved path as the baseline for text, which can crawl along the
path. You create and edit paths using the shape drawing tools. Like other objects, you can
move, scale, and rotate the path in three-dimensional space.
On the timeline, you will notice that the spline object media type has a path track instead of
a media track. You can nest Path tracks inside Face tracks in shapes. Unlike most media
tracks, you can animate path tracks. When the Path track is selected, its you can use the
controls in the Controls window to set the stroke and/or fill, to add borders or shadows, to
create animated stroke effects, and to jitter the spline.
n
The Path controls affect the spline or splines selected in the Composite window.
The Path Track and 3D Plane Shape
The Path track for a 3D plane shape is nested inside the Face track, which includes a mask
track allowing you to create upstream masks. See “Upstream and Downstream Masks” on
page 179.
The transformations tracks nest tracks that let you adjust Brush and Layer properties.
Seed Randomly varies the jitter from frame to frame.
Velocity Controls the speed of the Jitter X and Jitter Y parameters.
Jitter X, Jitter Y Vary the positions of each control point along the X and Y
axes.
