3 Rename the new folder to suit your needs.
This new folder appears in the subcategory column whenever that category is selected.
To remove objects or folders from a Content category:
m Select an object or folder in the Library stack, then do one of the following:
 Choose Edit > Delete.
 Press Command-Delete.
When Library Media Becomes Unavailable
As with any other object used in a Motion project, Library media used by a project
must be present and installed on the current computer for those objects to appear
correctly in Motion. If someone gives you a project file and you don’t have the same
filters, fonts, or LiveFonts that they do, a warning appears when you open the project
that lists the items that are unavailable.
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.
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.
