Lesson 6. Adjusting Edit Points > Working in the Trim Edit Window

Working in the Trim Edit Window

Before you make trims or adjust any clips, let's look at how the Trim Edit window works.

From the Browser, open the Amanda Trim Edit sequence.

This is the rough sequence you used in the previous lesson to practice trimming. But in this sequence, the narration clips have been removed so you can concentrate on the dialogue clips.

Make sure you have the default Selection tool selected and that linked selection is toggled on.

To open the Trim Edit window, double-click the edit point between the first two clips in the Timeline: 97A-out of bldg and 97E-man.


Clicking the Timeline will automatically close the Trim Edit window. To reopen an edit point in the Trim Edit window, simply double-click the edit point in the Timeline.

A large window opens that covers the Viewer and Canvas windows. The image area on the left displays the outgoing 97A-out of bldg clip. The image on the right displays the incoming 97E-man clip.


You can reposition the Trim Edit window in the interface by dragging from its title bar.

In the outgoing clip's scrubber bar is an Out point, and in the incoming clip's scrubber bar is an In point. These are the two edit points that can be adjusted in the Trim Edit window, either separately with the Ripple tool, or together with the Roll tool.

Beneath and between the two image areas are transport controls and trim buttons. The clip name, duration, and timecode location appear above each clip in the window. The sequence location of the edit point appears beneath the window name between the two image areas.

Move the pointer into the outgoing clip area on the left.

The pointer changes to the Ripple tool, which will adjust only the Out portion of this edit.

Click the outgoing clip's image in the Trim Edit window.

In the Timeline, the outgoing clip's Out point is highlighted. In the Trim Edit window, the green bar appears above just this image.

Move the pointer into the incoming clip on the right, and the pointer changes, but not the edit point selection in the Timeline or the green bar over the image. Click the incoming image to change the edit point selection in the Timeline.

The green bar now appears over the incoming clip.


The green bar is a good visual clue as to which side of the edit is currently selected. That is the side that will be changed.

Move the pointer to the middle area between the two image frames, and a Roll tool appears. Click here, and both edit points are selected in the Timeline, and a green bar appears over both image areas.

Using the Roll tool here will change both clips' edit points by the same amount and will not change the length of the sequence.

Click the Play Around Edit Loop button, or press the spacebar, to play around the edit point. The edit point plays in the right image area; the left image area is dimmed during the preview.

The preview is looped and will continue until you stop it by clicking the Stop button or pressing the spacebar again.

To change the length of time the clip plays before the edit point (pre-roll) and after it (post-roll), press Option-Q to open the User Preferences window. Click the Editing tab and change the Preview Pre-roll and Preview Post-roll to 3 seconds, then click OK.

In the Trim Edit window, position the pointer over the outgoing clip and press J to move the playhead earlier, toward the dimmed In point. Press L to play forward from this location, or click the outgoing clip's Play button.

Even though you can't change the In point of the outgoing clip in the Trim Edit window, it still appears as a reference.
