With the bulk of my edit completed, I need to layer some different camera angles during the ceremony and sync the audio. While FCPX has audio sync capability, I haven’t found it to be as user-friendly as Singular Software’s popular PluralEyes multicam sync application (which is currently not available for FCPX). But during the SDE I was able to sync three video clips to one audio clip from our R44 external recorder fairly easily.
