To make it easier to align clips with one another or with particular points in time, you can activate the snap feature. When you move a clip with snap on, it automatically aligns with, or snaps to, the edge of another clip, a marker, the start and end of the time ruler, or the current‑time indicator. Snapping also helps to ensure you don’t inadvertently perform an insert or overlay edit when dragging. As you drag clips, a vertical line with arrows appears and indicates when clips are aligned.
