Parameters .
Seeing the Relationships Between Objects
There are two object parameters where you can see the relationship between objects in
the Layers tab and objects in the Media tab.
• The Media parameter appears in the Properties tab of the Inspector whenever you
select an object in the Layers tab. The Media parameter is an image well that displays
the source media in the Media tab to which the currently selected object corresponds.
• The Linked Objects list appears in the Media tab of the Inspector whenever you select
an object in the Media tab of the Project pane. This list displays all objects in the Layers
tab that correspond to the selected source media. Changing an object’s name in the
Layers tab automatically updates the name that appears in the Linked Objects list.
Using the Reveal Source Media Command
A fast way to find any layer’s source media in the Media tab is to use the Reveal Source
Media command.
To reveal a layer’s source media in the Media tab
Do one of the following:
µ
Control-click a layer in the Canvas, Layers tab, or Timeline, then choose Reveal Source
Media from the shortcut menu.
µ
Select the layer, then choose Object > Reveal Source Media (or press Shift-F).
The Inspector opens and displays the Media tab. At the same time, the Media tab in the
Project pane opens. The source media is selected, and its Media tab parameters are
exposed in the Inspector.
Online Versus Offline Media
As mentioned earlier, adding a layer to a Motion project creates a link between the layer
in your project and its corresponding media file on disk. When you delete, move, or
rename files on disk that are linked to layers in Motion, those files go offline, meaning
that they’re temporarily unavailable to your project. This can also happen if you give
someone a project file without also providing them with the source media it uses.
