For a media-editing application, some embodiments provide tools for editing media clips, such as dynamic editing and playback of media clips. In some embodiments, dynamic editing allows a user of the media-editing application to perform operations on a media clip while the media clip is being played back. Examples of dynamic editing operations include tagging instances in time of the media clip, splitting the media clip into multiple media clips, trimming the ends of the media clip, and extending a trimmed media clip, among other operations. In addition, to composite media clips, some embodiments also allow the user to create sequences of media clips, reorder the media clips within sequences, stack sequences, and add or remove media clips from sequences. Some such embodiments allow the user to composite media clips while some or all of the media clips are being played back. |
