To detach audio from a clip, just right-click the clip in the timeline and choose Detach Audio. You can keep the audio going and split a clip and insert a photo montage, for example - it will sound better than if the audio drops out while the photos play. You can do interesting things by detaching the audio from a video clip. To split a clip, just right-click the point in the clip on the timeline where you want to split it and choose Split Clip. You can split the clip into multiple clips and trim out the parts you don't want. If you've got an overly long clip, you might lose your audience's interest by the end of it.

Double-click the photo in the timeline and then you can tweak the start and end points for the Ken Burns effect. You can change the duration of the photo by clicking on one of its edges in the timeline and sliding it - just as you would when trimming a video clip. To add a photo, click Photo Library in the Libraries section along the left edge and then drag photos to the timeline as you would a video clip.īy default, photos are given a duration of four seconds along with the Ken Burns treatment. You can add photos to your movie to break up the video clips, which can make the proceedings a bit more interesting.
