This will put it in a regular audio track which is less buggy and easier to work with than the dedicated background audio track. It's possible to nudge the audio around once it's in the timeline by interacting with the drag handles of the corresponding timeline element, but this will be done one painstaking frame at a time and eventually just stops moving it. Copy/paste is easier in the long run. ok ok, but, can I copy and paste build in song's in iMovie in the play hed posision? sorry for my typo. yes I just gave it a try. Make sure the song name is in the VO cursor focus and then simply copy, move the playhead where you want the audio to start, and paste. thank you thankYou, it works for mi.
