Edit in the group track

There are a variety of editing tasks you can perform directly in the group track. This is equivalent to making similar edits to the various tracks contained within the group, but it’s sometimes more efficient to make such changes in the group track instead.

Move all objects in a group at once

Drag the upper group bar left or right.
All objects in the group move in time.

Move a single object in a group

Click an area of the lower group bar where a single object is visible.
That object is highlighted in the group track.
Drag the section left or right to move the object in the group forward or backward in time.
The selected object moves in time.

Move overlapping (composited) objects in a group

Drag an area of the lower group bar where multiple objects overlap.
The composited objects move in time.

Trim objects in a group

Drag an end of the upper group bar right or left in the track area.
Objects in the group that share the same In and Out point with the group are trimmed along with the group.

Change the duration of the group independently of the objects in it

Holding down the Command key, drag either end of the upper group bar left or right.
Only the group is trimmed.

Note: After you manually change the length of the upper group bar, it’s no longer updated when you add or modify the objects to the group. To restore automatic updating, realign the edges of the upper group bar with the edges of the first and last clips in the group.

Slip a video layer via the group track

Holding down the Option key, drag an area in the lower group bar where the video layer is located.
If there are overlapping (composited) layers, before performing this operation Control-click the overlapping region, then choose the desired video layer from the shortcut menu.

Note: You can only slip a layer if it has been trimmed first. For more information on slipping, see Slip video layers in the Timeline track area.

Dragging right slips the video clip to an earlier portion of the source media. Dragging left slips the video clip to a later portion of the source media. Either way, the position of the clip in the Timeline and its duration are unchanged.
