Playhead
The vertical indicator in the timeline or in a browser filmstrip marking the current position in a video or clip. You use the playhead to scrub, or move through a project or clip and play it back from different locations.
To move the playhead, do one of the following:
In the timeline: Drag the playhead left or right in the ruler, or tap a new location in the ruler.
In a browser filmstrip: Drag the vertical white line left or right, or tap a new location in the filmstrip.
If you have a Magic Trackpad or the latest iPad Pro and Apple Pencil, you can turn on skimming, which lets you drag in the timeline to preview your sequence without changing the playhead position.
To skim clips in the timeline:
Tap Options in the upper-right corner of the timeline, turn on Skimmer Playhead (you may have to scroll down), tap Done, then drag over clips in the timeline by swiping in the Magic Trackpad, or move the tip of Apple Pencil over clips in the timeline without touching the screen.
