1 Select the clips, and choose Sequence > Apply Default Transitions To Selection.
2 Start typing the transition name in the search box in the Effects panel. As you type, Premiere Pro displays all effects and transitions (audio and video) that have that letter combination anywhere in their names. Type more letters to narrow your search.
3 Drag the replacement transition on top of the transition you’re rejecting. The new transition inherits the timing of the effect it replaces (but not other settings, like border colors).
4 Use the Selection tool to drag the edge of the transition icon in the Timeline, do the same thing in the A/B timeline display in the Effect Controls panel, or change the Duration value in the Effect Controls panel. You can also double-click the transition icon in the Timeline panel and change the Duration value in the dialog box that appears.
5 Apply an audio crossfade transition to the beginning of the clip.
