Using the Trim Edit Window

You use the Trim Edit window to trim one or more edit points at a time. When trimming multiple edit points at once, you can choose which edit point the Trim Edit window displays and trim each edit point differently. If you change the type of edit you are performing in the Trim Edit window, this change affects all of your selected edit points.

Playing Incoming and Outgoing Clips in the Trim Edit Window

If you are performing a ripple edit in the Trim Edit window, the side of the Trim Edit window with a highlighted green bar is controlled by the J, K, and L keys. However, if you are performing a roll edit, both sides are highlighted. In this case, you choose whether the outgoing or incoming clip is controlled by the J, K, and L keys by moving the pointer over the outgoing or incoming side of the window. The Play button on the active Trim Edit viewer is highlighted.

Important: The Space bar does not control playback on the incoming or outgoing sides of the Trim Edit window.

To turn on playback with the J, K, and L keys in one side of the Trim Edit window
  1. Move the pointer over the side you want to play.

    The Play button is highlighted to indicate the side is active.

  2. Use the J, K, and L keys to control playback on that side.

Dynamic Trimming

When the Dynamic Trimming checkbox is selected, the selected edit point moves to the new position of the playhead whenever you use the J, K, or L keys. Press L to move forward, press J to reverse playback, and press K to stop. Press J or L repeatedly to speed up and slow down playback. Press K and either L or J together to perform slow-motion playback. The playhead in the active Trim Edit viewer moves until you press K to stop. When playback stops, the edit point in the active Trim Edit viewer is adjusted to the new position of the playhead. A ripple or roll edit is performed depending on whether one side of the edit point is selected, or both.

Trimming an Edit in the Trim Edit Window

    • To switch between the three available trimming modes: Press the U key.

    A green bar appears above either or both sides of the edit to show you what kind of trimming operation you’re performing.

  4. Trim the edit point by doing any of the following:

    • Click the trim buttons or use their keyboard equivalents to trim to the left or right using the displayed frame increments.

      • To trim backward or forward one frame: Press Left Bracket ([) or Right Bracket (]).
      • To trim backward or forward five frames: Press Shift-Left Bracket ([) or Shift-Right Bracket (]). The number of frames to trim can be customized with the Multi-Frame Trim Size setting in the Editing tab of User Preferences. For more information, see Choosing Settings and Preferences.
    • Type a plus sign (+) or a minus sign (-) and the number of frames to add or subtract, then press Return.

    • Drag an edit marker in the scrubber bar to a new point in the outgoing or incoming clip.

    • Use the jog and shuttle controls to move the playhead within the outgoing or the incoming clip. Then set a new Out point for the outgoing clip by pressing O or a new In point for the incoming clip by pressing I.

    • Use the playback controls to play the clip. Set a new Out point for the outgoing clip or a new In point for the incoming clip.

    • Use the J, K, and L keys to shuttle the playhead on either side of the edit point (you choose which side by positioning the pointer there). As you move the pointer between the left and right sides of the Trim Edit window, the left and right Play buttons become highlighted. Don’t click, or you’ll change the selected trim operation.

      Press L to move forward, press J to reverse playback, and press K to stop. Press J or L repeatedly to speed up and slow down playback. Press K and either L or J together to perform slow-motion playback.

      If the Dynamic Trimming checkbox is selected, the selected edit point moves to the new position of the playhead whenever you stop playback.

    For all the above trimming methods, the In Shift and Out Shift fields show the total number of frames that have been modified. The sequence and playhead in the Timeline automatically update to reflect your changes.

  5. Review your edit.

    See Reviewing and Playing Back Your Edits in the Trim Edit Window.

  6. To trim another edit point in the same track, use the Go to Previous Edit and Go to Next Edit buttons to move to another edit point and display it in the Trim Edit window.

    You can also select one or more edit points in the Timeline, and then go back to the Trim Edit window to perform additional trim operations.

  7. When you have finished trimming, do one of the following:

    • Move the playhead away from the edit point in the Canvas or Timeline.

    • Click in the Timeline to deselect all edit points.

    • Close the Trim Edit window.

Reviewing and Playing Back Your Edits in the Trim Edit Window

There are several ways you can play back your edits in the Trim Edit window, as well as review them.

To play the edit using the transport controls
Do one of the following:
  • Click the Play In to Out button to play from the beginning of the first clip to the end of the second clip.

  • Click the Play Around Edit Loop button or press the Space bar to loop the playback of the edit. Extra frames surround your edit point, defined by the pre-roll and post-roll settings specified in the Editing tab of the User Preferences window. For more information, see Choosing Settings and Preferences.

  • Click the Stop button to stop playback and position the playhead on the edit.

To view an individual clip in the Trim Edit window
Do one of the following:
  • Use the playback controls for the outgoing or incoming clip.

  • Activate the outgoing or incoming clip by moving your pointer over it. Press L to move forward, press J to reverse playback, and press K to stop. Press J or L repeatedly to speed up or slow down playback. Press K and either L or J together to perform slow-motion playback.

    Tip: As you use the J, K, and L keys, the audio shifts pitch smoothly rather than stuttering, as it does when you scrub. For more information, see Listening to Audio While Trimming.

Slipping a Clip in the Trim Edit Window

The Slip tool changes the clip’s In and Out points simultaneously while maintaining the clip’s duration. Surrounding clips are not affected. You can slip either of the clips displayed in the Trim Edit window.

To slip an edit in the Trim Edit window
  1. Double-click an edit point in the Timeline to open it in the Trim Edit window.

  2. Do one of the following:

    • Shift-drag the edit point in either scrubber bar to slip that clip.

    • Select the Slip tool in the Tool palette, then drag the edit point.

    As you drag, the display shows the In and Out point frames for the clip you are slipping.

  3. Release the mouse button.

  4. When you’ve finished trimming, close the Trim Edit window.
