Only the upper group bar is trimmed.
Note: After you manually change the length of the upper group bar, it is no longer
updated when you add or modify the objects to the group.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.
You can use this same technique on image and video object bars, trimming them without
affecting the duration of their subobjects (masks, filters, or other applied effects objects).
To trim an image or video object bar without trimming its applied effects
µ
Press Command while you drag the edge of the image or video object bar.
The image or video object bar is trimmed independently of its applied effects objects.
Slipping Video Layers Via the Group Track
In addition to moving and trimming, you can slip video layers in the group track. Any
portion of the lower group bar that contains only one video layer can be slipped in this
manner. Areas where more than one layer overlap can be slipped by Control-clicking the
group bar and choosing a video layer from the shortcut menu.
To slip a video layer via the group track
µ
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 video layer from the shortcut menu.
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.
Note: You can only slip an object if there are unused frames in the source media associated
with that clip. For more information on slipping, see Slipping Video Layers.
