There are many ways to combine multiple pieces of media in Sony Vegas. Some like to place their media on multiple tracks and split / delete what they don’t need from higher tracks in order to “let through” the lower tracks. Some slice their clips up in the trimmer first. Some even avoid multiple tracks altogether.
