Trim with Trim-in and Trim-out tools

You can change a clip’s In point or Out point by dragging its edge in a Timeline panel. As you drag, the current In or Out point appears in the Program Monitor. A tool tip displays the number of frames that you are trimming: a negative value if you are dragging the edge toward the beginning of the sequence and a positive number if you are dragging toward the end of the sequence. You cannot trim past the original In and Out points of the source footage.

 Click the selection tool  and do one of the following:
  • To edit the In point, drag the left edge of the clip once the Trim‑in icon  appears.

  • To edit the Out point, drag the right edge of the clip once the Trim‑out icon  appears.

    Note: To trim only one track of a linked clip, press Alt (Windows) or Option (Mac OS) as you click with a Trim icon. You do not need to hold down the Alt (Windows) or Option (Mac OS) key once you initiate the trim. To ripple trim a clip, press Ctrl (Windows) or Command (Mac OS) while dragging.
    Trimming a clip

    Trimming in this way affects only a single clip edge and doesn’t affect adjacent clips. To trim multiple edges at once or to shift adjacent clips, see Perform rolling and ripple edits and Perform slip and slide edits.

    Press Ctrl (Windows) or Command (Mac OS) as you drag using the Selection tool to switch to the Ripple Edit tool.
