While insert, overwrite, and replace are the editing operations you use most often, there are other editing options available. For each of these operations, you select your source clip in the same manner as for an insert, overwrite, or replace edit. Then you select the appropriate editing operation from the Secondary Edit box. 
-
- An Aligned Edit is usually performed on two tracks. You set the positioner on the timeline to an point you want to align to, then move the focus point of the positioner to a different track. Set the positioner of the source track to the point you want aligned. The source clip is added to the track, and both points are aligned.
-
- Append applies an edit that adds your source clip to the end of the edit sequence on the timeline.
-
- Prepend applies an edit that adds your source clip to the beginning of the edit sequence on the timeline.
-
- Ripple Replace functions as a combination of an insert and replace edit. The source clip replaces the selected clip on the timeline, and the all of the clips to the right ripple to accommodate the length of the new clip.
-
- Replace Media performs a replace edit but retains any effects applied to the replaced clip or clips on the timeline.
-
- A Fit To Fill edit functions as a replace edit, but instead of adding tail frames to a longer source clip, a Timewarp is added to the replaced clip so that it fits the same space occupied by the clip it is replacing.
