Some embodiments provide a media-editing application. The application displays a trackless composite display area for creating a composite presentation from several different media clips. The composite presentation includes a multi-camera media clip that includes one of several different groups of ordered media clips. Upon receiving a selection to edit the multi-camera media clip in the composite presentation, the application displays each of the different groups of ordered media clips as separate tracks in the composite display area.

A novel method for retiming a portion of a media content (e.g., audio data, video data, audio and video data, etc.) in a media-editing application is provided. The media editing application includes a user interface for defining a range in order to select a portion of the media content. The media editing application performs retiming by applying a speed effect to the portion of the media content selected by the defined range. For a faster speed effect, the media editing application retimes the selected portion of the media content by sampling the media content at a faster rate. For a slower speed effect, the media editing application retimes the selected portion of the media content by sampling the content at a slower rate.

Some embodiments of the invention provide a media-editing application for creating and editing a media presentation that displays the results of edits as the edits are made to the media presentation. The media-editing application displays the movement of media clips of the media presentation as the media clips are being moved within the media-editing application to change the media presentation. Also, the media editing application in some embodiments can dynamically display the results of edits in a preview display area. That is, the media editing application has a preview generator that can generate previews of the media presentation on the fly as media clips are being dragged into and within the timeline. This allows the user of the media-editing application to see and hear the results of the operation while performing them.

Some embodiments of the invention provide a keyword association tool for organizing media content. Each keyword can be associated with an entire clip or a portion of the clip. For each specified keyword, the keyword association tool creates a collection (e.g., bin, folder, etc.) in a dynamic collection structure. In some embodiments, a keyword collection is dynamically added to the collection structure each time a new keyword is associated with a media clip. To associate a clip with a keyword, a user can drag and drop a clip onto a keyword collection that corresponds to the keyword. The same technique can be used to associate multiple clips with the keyword by simultaneously dragging and dropping the clips onto the keyword collection.

Systems and methods for previewing edited video. In general, in one implementation, a method includes generating a video sequence from a plurality of video segments, identifying an inability to output at least one video segment in the video sequence in substantially real time; and adjusting an output level associated with the at least one video segment to enable the at least one video segment to be output in substantially real time. The output level may include a video quality or a frame rate.

Some embodiments provide a media-editing application. The application includes several image processing destinations for performing operations on video images. The application includes a scheduling engine for scheduling disk read, decode, and graphics processing operations to perform on images to prepare the images for the several destinations. The scheduling engine includes a first set of instructions for scheduling images based on a speed at which a particular one of the several destinations processes the images when none of the destinations require images in real-time. The scheduling engine includes a second set of instructions for scheduling images based on a real-time clock when at least one of the several destinations requires images in real-time.

Some embodiments provide a media-editing application. The application defines a reference clip data structure for a media clip that represents one or more media files imported into the media-editing application. The application receives a command to add the media clip into a composite media presentation. The application defines a clip instance data structure as part of the composite media presentation. The clip instance data structure inherits properties of the reference clip data structure and subsequent modifications to the reference clip data structure affect the clip instance data structure.
