Add Image to Mask: Adds an image mask to the selected layer. An image mask creates
transparency in another object by deriving an alpha channel from another layer, such
as a shape, text, movie, or still image. For more information, see “
Make Clone Layer: Clones the selected layer. Like the Duplicate command, Make Clone
Layer lets you make copies of a selected layer. However, copies created by the Make
Clone Layer command are automatically modified to match certain changes you make
to the original layer. For more information on cloning layers, see “
Reveal Source Media: Opens the Media tab and highlights the media file associated
with the selected clip.
Media Tab
The second tab in the Project pane contains a complete list of media in your project.
“Media” includes imported audio, image, image sequence, and QuickTime movie files.
Unlike the Layers tab, the Media tab may contain items that are not actively used in
your project. Also, if you’ve used a single layer repeatedly, the Media tab may only
show one version of that layer. Effects (such as filters or masks) and other layers created
within Motion (such as masks, shapes, or text) do not appear in the Media tab.
To display the Media tab, do one of the following:
m
Choose Window > Media.

To display the additional columns in the Media tab, drag the divider between the
Project pane and the Canvas (the vertical bar on the right side of the window).
The Media tab provides a great deal of technical information about the media files in
your project. This data is displayed in the following columns for each file:
Preview: Shows a thumbnail of the media file. The thumbnail for an audio file (with no
associated image) appears as a speaker icon.
Name: Contains the name of the media. Media names are not editable because they
refer to the actual names of the files on disk.
