Apple Motion 4 - Manual (Page 264)

You can either close the project and install the necessary files on your computer, or go
ahead and open the file. The following list outlines what happens when you open a
project file without having the necessary media:
• Missing Content: Missing content is treated like any other missing media object. The
objects go offline, and you have the option to reconnect them at any time. For more
information about reconnecting media, see
Online Versus Offline Media .
• Missing Filters: When one or more filters are missing, objects in your project that use
those filters appear with a placeholder that shows which filter is missing. This gives
you the opportunity to reinstall the filter at a later point.
• Missing Fonts: When fonts are missing, the text objects that use those fonts default to
Geneva as a temporary substitute. Missing international fonts substitute the default
system font for that language.
• Missing LiveFonts: When LiveFonts are missing, the previously used LiveFont is replaced
by another LiveFont installed on your computer.
Organizing Groups and Layers in Motion
Whenever you drag a media file from the Library or File Browser into the Canvas, Layers
tab, or Timeline, or generate an image from within Motion, the resulting element is
represented as a layer. Think of layers as a series of clear overlays stacked one on top of
the other. These layers combine to create the composite that you see in the Canvas.
Motion provides a graphical representation of this layer hierarchy in the Layers tab of the
Project pane and also in the Timeline layers list. You can rearrange the stacking order of
the layers in your composition by dragging them to a new location in either of these lists.
Layers, in turn, are nested within containers known as groups. Whenever you create a
new layer, that layer is placed within a group. You can drag a layer from one group and
place it inside another group, but layers cannot exist on their own, outside of a group.
Layers nested inside groups appear indented in the Layers tab and the Timeline layers
list.
