Clip editing in final cut pro x
Simple question, but I can't figure out the answer. Normally when I edit a clip in the timeline (cut a piece out or trim from the edge), the other clips automatically close that space and the entire clip moves together. In a recent editing session, I must have turned off a feature or changed a setting because now the clips don't stay together. Every trim or edit leaves a gap and I theoretically have to move each piece over so that they stay connected. Don't know how to reset this feature/setting because I don't know what to look for or what it's called. I know it's a simple fix. Please help! Thanks
