Using the Trim view


The Monitor window Trim view is a precise way to trim clips interactively in any video track. You can perform ripple or rolling edits at any edit along the Timeline. As you make adjustments, you see the frames on both sides of the edit. You can also set a range of frames you see on both sides of the edit to expand your view of the context of the edit. The Timeline updates as you perform the edit.

When you're not in Trim view, the left monitor displays source clips and the right monitor displays the program. When you use the Trim view, both monitors represent clips in the program--the left monitor is the clip to the left of the edit line, and the right monitor is the clip to the right of the edit line.

Note: When you perform any action that requires moving a clip's In or Out point outward, such as adding frames in the Trim view, additional frames must be available in the clip's source (master) clip beyond the current In or Out point. For example, if you didn't trim the beginning or ending of a source clip before adding it to the Timeline, the edit line may already be at the first or last frame available from the source, so you will not be able to move its In or Out point any further out.

To switch to Trim view:

Click the Trim Mode button () at the top of the Monitor window. You can also choose Trim Mode from the Monitor window menu.

To find the edit you want to trim:

1 Select the target tracks in the Target drop-down menu.

2 Click the Previous Edit () or Next Edit () buttons. The frames on either side of the new edit line position appear in the Monitor Trim view.

    2 In the Trim Mode Options section, select one of the following options:
  • Click the first view option to display the frame to the left of the tail (the clip to the left of the edit line) and the frame to the right of the head (the clip to the right of the edit line).
  • Click the second view option to display the tail of the left clip with small representations of the frames before and after the tail, and the head of the right clip with small representations of the frames before and after the head.
  • Click the third view option to display--from top to bottom--small representations of the fifth and first frames before the tail of the left clip or the head of the right clip, a large representation of the tail or the head, and small representations of the first and fifth frames after the tail or head.

    • 3 For Large Frame Offset, specify the number of frames that will be trimmed when you use the multiple-frame trim buttons ([] or []) that trim five frames by default.

    4 Select Play Previews at Maximum Size when the program frame size is smaller than the available space in the Monitor window and you want trim previews to appear at the largest size that fits in the Monitor window. Then click OK.
