The duration of a clip is the length of time it takes to play from the In point to the Out point. You can set a duration for video or audio clips, letting
them speed up or slow down to fill the duration. You can do the same for still-image clips, but without the changes in speed.
You can change the speed and duration for one or more clips at a time.
You can also set clip speed to fill a duration by performing a four-point edit.
