Chapter 11. Fine Cut: Trimming Edits > Types of Trimming Operations

Types of Trimming Operations

Each trim edit type can solve a particular editing problem, so it’s a good idea to become familiar with the whole palette—maybe even try them all in advance. (If you would like to review FCE’s basic editing types, return to Chapter 9, “Basic Editing.”)

  • Ripple: A Ripple edit adjusts the length of one clip in a sequence by changing either the In or the Out point of that clip. A Ripple edit accommodates the change by rippling (or shifting) the timecode location of the clips that come after the adjusted edit, without affecting the clips’ duration. Use a Ripple edit if you want to adjust the length of a clip in a sequence without losing sync or creating a gap. Locked tracks will not be rippled. For example, the Close Gap command in the Timeline performs a Ripple Delete edit.

    Figure 11.1 shows a Ripple Left edit, in contrast to Figure 11.2, which shows a Ripple Right edit. Note the differences in the pointer and in the selected edit points.

  • Roll: A Roll edit (Figure 11.3) adjusts the location of an edit point shared by two clips. A rolling edit makes the change by subtracting frames from clip A on one side of the edit to compensate for the frames added to clip B on the other side of the edit. The overall duration of the sequence remains unchanged, but the location of the edit in the sequence is changed.

    Figure 11.3. A Roll edit, as performed in the Timeline.

  • Slip: A Slip edit (Figure 11.4) is an adjustment made within a single clip. When you slip a clip, you select a different part of that clip to include in the sequence, while maintaining the same clip duration and timecode location in the sequence. Surrounding clips are not affected, and the sequence duration does not change.

    Figure 11.4. A Slip edit, as performed in the Timeline. The selected portion of the clip has shifted –14 frames.

  • Slide: A Slide edit (Figure 11.5) moves a single clip in relation to those before and after it, so that the durations of the clips on either side change, but the In and Out points of the clip you’re sliding remain the same. The clips immediately adjacent to the sliding clip accommodate the change; the overall sequence duration does not change.

    Figure 11.5. A Slide edit, as performed in the Timeline. The selected clip has slid 1 second, 21 frames later in the sequence.

  • Swap: A Swap edit (Figure 11.6) doesn’t alter any sequence clips, but it does change the order in which the clips appear in the sequence. Perform a Swap edit in the Timeline by selecting a clip, dragging it to a new location, and placing it into the sequence using an Insert edit.

    Figure 11.6. A Swap edit, as performed in the Timeline. The two clips will swap positions.

  • Extend: An Extend edit (Figure 11.7) moves a selected edit point to the playhead position by extending the clip’s duration, rolling over any gaps or clips that are encountered. You can extend an edit only to the maximum length of that clip’s media. An Extend edit is a useful way to fill sequence gaps without affecting the sequence duration.

    Figure 11.7. An Extend edit. Select the edit point of the clip you want to extend to the playhead position.

  • Resize: The Selection (or Arrow) tool can be used to resize a clip in the Timeline by dragging an edit point (Figure 11.8). You can drag the edit point to create a gap (by making the duration of the clip smaller) or to cover an existing gap.
