Media-editing application with anchored timeline

摘要

A media application of some embodiments includes a timeline, which is a composite display area for displaying media clips that are part of the composite media presentation. The timeline of some embodiments includes a primary lane called a spine as well as one or more anchor lanes. The spine represents a primary sequence of media, which, in some embodiments, does not have any gaps. When a clip is deleted or removed from the timeline, the media-editing applications automatically closes the gap created in place of the clip. The clips in the anchor lanes are anchored to a particular position along the spine. Anchor lanes may be used for compositing (e.g., removing portions of one video and showing a different video in those portions), B-roll cuts (i.e., cutting away from the primary video to a different video whose clip is in the anchor lane), audio clips, or other composite presentation techniques.

主权项

1. A non-transitory machine readable medium storing a program for creating a composite media presentation from a plurality of media clips which when executed by at least one processing unit presents a graphical user interface (GUI), the GUI comprising:
a preview display area for displaying the composite media presentation; a composite display area for placing media clips to specify the composite media presentation, the composite display area comprising:
a first playhead for specifying an editing position; anda second playhead for specifying a skimming position based on a position of a position indicator in the composite display area, wherein as the second playhead moves in the composite display area, the preview display area displays frames associated with the skimming positions in the composite display area that are traversed by the second playhead, wherein when (i) the second playhead intersects a primary clip that is displayed as a part of the composite media presentation and a secondary clip that is not displayed as a part of the composite media presentation and (ii) the position indicator does not specify a position on either of the primary and secondary media clips, the preview display area displays frames of the primary media clip.
