Constant speed changes also usually alter the duration of a clip. By default, if a constant speed
change causes the duration of a clip to become longer or shorter, all clips coming after it ripple
forward or backward. If you change the speed to 50 percent, your clip becomes twice as long,
and subsequent clips are moved to the right; if you change the speed to 200 percent, the clip
becomes half as long, and subsequent clips ripple left. For example, if you set a 5-second clip
to play back at 50 percent speed, Final Cut Pro adds frames to the clip so that the clip becomes
10 seconds long and plays back more slowly. If you increase the clip’s speed to 200 percent,
Final Cut Pro removes frames and the clip plays back in only 2.5 seconds.
