Trimming Clips in the Viewer

You can trim clips in your sequence by opening them in the Viewer and adjusting the clip In and Out points.

To open a clip in your sequence in the Viewer
Do one of the following:
  • Double-click the clip in the Timeline.

  • Select a clip in the Timeline, then press Return.

  • Double-click the clip in the Canvas. The clip currently beneath the playhead is opened in the Viewer.

  • If the clip is in a nested sequence, hold down the Option key, then double-click the clip.

    Note: If you just double-click the nested sequence, the nested sequence opens as a sequence tab in the Canvas and Timeline, not as a clip in the Viewer.

When a sequence clip is opened in the Viewer, the scrubber bar shows sprocket holes to indicate that the clip is part of a larger sequence. Always check the scrubber bar in the Viewer to make sure you are working with a clip from a sequence instead of a clip opened from the Browser.

When you open a sequence clip, it opens in the Viewer to the same frame where the playhead is positioned in the Timeline or Canvas. If the Timeline playhead was beyond the clip’s In or Out point, the Viewer playhead is placed on the clip’s In or Out point, whichever was closest to the Timeline playhead.

To trim a clip in the Viewer
  1. Open a clip from your sequence in the Viewer.

    The scrubber bar shows virtual sprocket holes, which indicate that the clip is from your sequence (not from the Browser).

  2. Do one of the following:

    • Use the transport controls or the J, K, and L keys to move the playhead in the Viewer to a new point in your clip. Then set a new In or Out point using the Mark In and Mark Out buttons or the I and O keys.

    • Drag the In or Out point along the Viewer’s scrubber bar to a new point in your clip.

You can’t set a new edit point or drag a clip’s edit point so that it overwrites an adjacent clip in the Timeline. If you try to, Final Cut Pro warns you that the clip you are trimming has collided with another clip in the Timeline, and the trim edit is not performed (see Understanding Alert Messages When Trimming). If you want to move a clip’s edit point so that it overwrites an adjacent clip, you should roll the edit point between the two clips using the Roll tool (see Using the Roll Tool to Change Where a Cut Occurs).
