Containers are a convenient way to remove clutter from the timeline by grouping elements together. The elements, which can come from different layers or tracks, are treated as one unit yet remain individually editable. Containers behave like any other element but they appear on a separate timeline when you enter their editor. You can add an unlimited number of containers to a container.

You set the Player to reflect the contents of the container timeline or of the record timeline.

To set preferences that affect container behaviour, see Containers.

To create a container:

1. Select all the tracks or layers on the timeline that you want to collapse into the same container.
   NoteThe bottom layer is always trimmed out so that you can dissolve from an element to a container.
2. Enable Container (or press Alt+' [tilde]).

   
   

   All the selected elements are collapsed into a container and the element changes to a dark blue. If you did not make any selections and you have in and out points, the container is created between the in and out points.

3. To edit the contents of the container individually, double-click the container, or click E beside the Container button.
   TipIf you do not see the Container button, select the container.

   The layers in the container appear on their own timeline. Yellow marks indicate the duration of the container.

4. Select a display option for the container from the View Modes box. You can display both the container timeline and the record timeline or just the container timeline.

To navigate in a container from the record timeline:

1. To move to the beginning of the container, press Ctrl+Shift+A.
2. To move to the end of the container, press Ctrl+Shift+S.
3. If you are displaying both the record timeline and the container timeline, you can scrub with the positioners synchronized by pressing Ctrl+Shift while scrubbing.

To remove a container:

1. Select the container.
2. Alt-click the LED on the Container button.

   The container is removed from the timeline and its contents are restored to the record timeline.
