Perform rolling and ripple edits

You can perform a rolling or ripple edit either directly on the tracks in a Timeline panel or using the Trim Monitor.

Select the Rolling Edit tool .
In a Timeline panel, drag left or right from the edge of the clip you want to change. The same number of frames added to the clip are trimmed from the adjacent clip. Alt‑drag (Windows) or Option-drag (Mac OS) to affect only the video or audio portion of a linked clip.

In the Trim Monitor, click the Select Video Or Audio Track button and select the track you want to edit.
Click in the Sync Lock box in the header of any track you want to shift when the rolling edit is made.
In a Timeline, place the current-time indicator at the edit point. This will display the edit point in the Trim Monitor.
Do any of the following:
- Position the pointer between the video images so that it changes into the Rolling Edit tool ; then drag left or right.
- Drag the center timecode display left or right.
- Drag the center jog disk left or right.
- Click the timecode display between the views, type a valid timecode number to trim the edges of both clips to that frame, and press Enter (Windows) or Return (Mac OS).
- Select the boxed number above the center jog disk, type a negative number to trim both clips left or type a positive number to trim both clips right, and press Enter (Windows) or Return (Mac OS).
- Click the button that corresponds with the number of frames you want to edit. The –1 and –5 buttons trim both clips left; +1 and +5 trim both clips right.
  
  Note: The large trim offset number is 5 frames by default, but you can set it to any number by specifying a number in the trim preferences. Choose Edit > Preferences > Trim (Windows) or Premiere Pro > Preferences > Trim (Mac OS).

Select the Ripple Edit tool .
In a Timeline panel, position the pointer over the In or Out point of the clip you want to change until the Ripple‑in icon or the Ripple‑out icon appears, and drag left or right. Subsequent clips in the track shift in time to compensate for the edit, but their durations remain unchanged. Alt‑drag (Windows) or Option-drag (Mac OS) to affect only the video or audio portion of a linked clip.
