As you edit, you may find yourself wanting to trim a clip so that it begins earlier or later, but you don’t want to change the clip’s duration. You can now use the Slip tool to slip the clip. Should you use the portion of the clip where a person is walking out of a room? Or earlier, when he’s walking into it? Slipping allows you to select slightly different content without changing the clip length. However, you must have additional material—handles—on either side of the clip, or you will have no additional frames to slip.
When you apply the Slip tool to a clip in the Timeline, think of the clip as what you see through your car windshield. The additional material to the left or right, outside your windshield view, is the handles of the adjacent clips. If an action occurs earlier or later in the clip, you can make it appear in the windshield by dragging the clip left or right using the Slip tool. You drag right to see earlier clip material (before the In point), or left to see later material (after the Out point).
