CHAPTER 9
Animating a Clip
Alpha: Create New
With this option selected, an alpha channel is created in the shape of the clip as it moves. This
option affects only those clips that have been assigned an alpha channel key type in the Trans-
parency Settings dialog box. See "Using the Alpha Channel key" on page 268.
Note: Choosing the Create New option for an image containing an alpha channel overwrites the
original alpha channel when the image is superimposed.
Saving, loading, and deleting motion settings
You can use the Save and Load buttons in the Motion Settings dialog box to save the motion
settings you create for a clip for later use with other clips. Motion settings are applied to entire
clips; they cannot be applied to a limited number of frames of a clip.
To remove all motion settings applied to a clip, click Remove in the Motion Settings dialog box.
Creates an opaque fill for clips that do not have an existing alpha channel.
