Adjusting clips in the Trim panel: Lesson 5-5
The Trim panel is a very useful tool. You used it in Lesson 2 to do some quick Ripple Edits. It also performs a so-called Rolling Edit. Its value is its large preview monitors, precise controls and informative timecode displays.Rolling and Rippling Edit behaviors
![]() | You apply a Ripple Edit to only one clip. It changes the length of your project as the rest of the project slides over to accommodate the change. A Rolling Edit does not change the length of your project. It takes place at an edit point between two clips: shortening one and lengthening the other. |
1. | Continue with Lesson 5-4 or open Lesson 5-5. |
2. | Marquee select the clips in the Lesson 5-3 Sequence and press Delete. |

6. | Hover the cursor over the left preview screen until it turns into a left-facing Ripple Edit cursor (![]() |
7. | Trim the right edge of clip (the out-point) by dragging it left to about one second (use the Out Shift timecode below the center of the left screen). |

9. | Click the precision trimming toolsthe 1 and +1 numbers (highlighted in the previous figure)to trim or lengthen the clips a frame at a time until you have matched the position of the dancer in both preview screens. I trimmed 1;04 from the left clip and 0;24 from the right. |

12. | Drag it left and right to change the out- and in-points of the left and right clips respectively. Notice how both clips move and the dancer's motions remain matched. |
13. | See if you can find a better edit point. I ended up by trimming 1;02 from the left and 0;26 from the right. |
14. | Click Play Edit.You might notice that you just gave the dancer one extra spin. |
