How Changing Speed Affects a Clip’s Duration
A change in a clip’s speed can affect the duration of the clip. If you choose 50 percent
speed, your clip is twice the duration; if you change speed to 200 percent, the clip
becomes half as long. For example, if you set a 10-second clip to play back at 50
percent, Final Cut Pro duplicates frames in the clip so that the clip becomes 20 seconds
long and plays back more slowly. If you increase the clip’s speed to 200 percent,
Final Cut Pro skips frames and makes the clip 5 seconds long, and it plays back
considerably faster.
Note: Speed settings you apply are not applied to that clip’s source media on disk, and
can be changed at any time.
Performing a Fit to Fill Edit
A fit to fill edit changes the speed of a clip in the Viewer so that its duration matches
the duration between the sequence In and Out points. Because a fit to fill edit changes
the speed of the edited clip, you may have to render it before it will play back. Also, any
audio items associated with this clip will change pitch, moving either higher or lower.
Fit to fill is the only edit type in Final Cut Pro that requires four edit points, instead of
three. You need to set In and Out points for your clip in the Viewer, as well as In and
Out points in the Canvas or Timeline, for the destination in your edited sequence. For
more information, see Volume II, Chapter 10, “Three-Point Editing.”
For example, suppose you want to replace a 5-second shot of a lizard with a 3-second
shot of a desert landscape. In this case, you can use the fit to fill edit to make the
landscape shot fit.
