Add objects to the Timeline
Add objects to the Timeline overview
When you drag a new media item into the track area, a drop menu appears with options for how
the new layer should be incorporated. Depending on where in the track area you drop the item,
the menu displays different options. If you drag to a group or layer track in the track area, you
can choose Composite, Insert, or Overwrite. An additional Exchange option becomes available
when you exchange the same type of media (such as a QuickTime movie, an image sequence, or
an image file). For example, the Exchange menu item is displayed when you drag a QuickTime
movie onto another QuickTime movie’s track.
Library effects (behaviors, filters, and so on) can also be dragged into the Timeline track area.
However, because effects objects are applied to media layers (images, clips, audio, and so on),
they cannot be grouped by themselves.
Objects such as cameras and lights that are saved to the Library can also be dragged to
the Timeline.
When you drag a media item the track area, a new layer appears in the Timeline layers list. The
new layer can appear above or below an existing layer; where you release the mouse button
determines placement of the new layer. If you drag multiple items, you can choose Composite
or Sequential from the drop menu. Composite places the new tracks one on top of the other.
Sequential places the new tracks one after the other.
Note: If you release the mouse button before the drop menu appears, the default choice
of Composite is applied. This means that a new track is added above the other tracks in the
Timeline, and the layer appears on top of other layers in the Canvas.
