Adding Objects to the Timeline Layers List
You can add images and clips to your project by dragging them to the Timeline layers
list. When you drag an image from the File Browser or Media tab into the Timeline layers
list, you can choose whether add the new object to an existing group, replace an existing
object, or create a new object. Once an object is added to the Timeline layers list, it
appears in the layers lists and becomes a Timeline track in the track area. The new object
can appear above or below an existing object; where you release the mouse button
determines placement of the new object.
Note: You can also add objects to the Timeline track area. For more information, see
Adding Objects to the Track Area .
To add an object to an existing group
1 Drag an object from the File Browser, Library, or Media tab, and position the pointer over
the Timeline layers list.
• If you position the pointer over a group, the track is highlighted with a black border.
• If you position the pointer between object tracks within a group, the position indicator
appears.
2 Release the mouse button to add the layer to the group.
The new layer is placed on top of other existing objects in the group, or in between the
objects where you dragged it.
To replace an object in an existing group
1 Drag an object from the File Browser, Library, or Media tab, and position the pointer over
the object that you want to replace.
A black highlight box appears around the object.
Note: The replace command can be used only for image, image sequence, and QuickTime
movie files.
2 Release the mouse button.
The new object replaces the old one.
To create a new group on top of existing groups
1 Drag an object from the File Browser, Library, or Media tab into the Timeline layers list,
at the upper edge of the top object.
