<span id="transition"></span>现在两个剪辑已经出现了重叠,可以添加过渡了。This is done either by right-clicking on the upper clip and choosing <menuchoice>Insert a Composition</menuchoice> and choose <menuchoice>Wipe</menuchoice> or, easier, by hovering the mouse over the lower right corner of the Spoon clip until the pointing-finger pointer is shown and the message "Click to add composition" appears. The latter, by default, adds a wipe transition, which is in this case the best idea anyway since the Spoon is not required for playing.
