Slip a video layer via the group track
In Motion, while pressing and holding the Option key, drag an area in the lower group
bar where the video layer is located in the Timeline track area.
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 in Motion.
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.
Navigate in the Timeline in Motion
Motion provides many controls for navigating the Timeline. You can drag the playhead
to “scrub” through your project as quickly or slowly as you want, or immediately jump
to a specific frame. Additionally, you can jump to object boundaries, markers, and other
important indicators in the Timeline.
Many navigation tasks are also accessible in the timing toolbar.
Note: The timing display can be set to show frames or timecode. To set the timing
display duration to frames, Click the down arrow on the right side of the timing display,
then choose Show Frames from the pop-up menu. See Switch between display of frame
numbers and timecode.
In addition to moving to new positions in time, you can navigate directly to objects in the
Timeline, such as objects, markers, and keyframes.
Play back your project
In Motion, do one of the following:
In the timing toolbar, click the Play button.
Press the Space bar.
For more options, such as advancing frame-by-frame or starting playback from the
beginning of the project, see Play back a project in Motion.
