The Texture Track button creates a Texture track in the timeline. This track
is a media track that allows you to map a still image, EPS, video, color,
gradient or natural media to Text, Spline Object and Spline Primitive
media. For information, see Mapping Media to Text on page 443.
The Path Track button creates a Motion Path track in the timeline. The
Motion Path is a media track which creates text on a path, that is, text
which wraps around a spline object.
The Text Backdrop button creates a backdrop behind text. The Backdrop
Track appears below the text’s Face track in the timeline. For information,
see Adding Color Backdrops to Text on page 445.
Toggles drop shadows off and on.
The Wireframe button toggles in and out of Wireframe view. Wireframe
displays the shape as an outline to speed previews. Deselect this option to
view the complete effect before rendering.
The Animate button toggles between default and constant interpolation.
Constant interpolation means no animation, where parameter adjustments
remain static and do not create keyframes, more useful for compositing
than animating. The top button selects the default interpolation (Ease in /
Ease Out, unless you change it); the lower button shows constant
interpolation.
The Analyze button generates motion tracking data. When you create a
motion key, you define the object (or part of the image) that you want to
key out as it moves, then you click the Analyze Motion button, and the
software analyzes the motion of the object so that it can key it out even as
it moves.
When a Media track is selected, opens a dialog box from where you can
browse to and select a media file to replace the current file.
