Some embodiments of the invention provide a GUI for a media editing application that provides visual cues (e.g., colors and/or lane sets) for media clips that are assigned different tags (or roles) in a media presentation. The GUI of the media application of some embodiments displays media clips of a composite media presentation, in which at least some of the media clips are associated with tags. The GUI also provides GUI controls for associating media clips associated with different tags with different colors and for displaying the media clips based on the clips' associated color. In some embodiments, the GUI includes a tool for arranging clips into groups based on assigned tags. The tool of some embodiments, upon selection, defines a set of lanes for each tag and displays any anchored clip that is associated with a tag in the set of lanes associated with the tag.

Organized timeline

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.

Retiming media presentations

A novel audio ducking method that is aware of the loudness levels of the audio content is provided. The method specifies a minimum loudness separation between audio tracks that are designated as masters and audio tracks that are designated as slaves. The method attenuates the volume of the slave tracks in order to provide at least the minimum loudness separation between the slave tracks and the master tracks. The amount of attenuation for a slave is determined based on the loudness levels of the slave and of a master.

Content aware audio ducking

In some implementations, a user can specify an audio control curve for an audio track. The audio track can include an audio signal that is sampled at a specified rate. The audio control curve can be used to generate an audio control signal that can be sampled at the same rate as the audio signal. The audio signal and the audio control signal can be combined to produce sample-accurate adjustments of the audio signal. In some implementations, the audio control curve can correspond to gain adjustments for the audio signal. In some implementations, the audio control curve can be used to adjust the amplitude of the audio signal at particular frequencies. The audio control curve can be used to adjust treble or bass levels during the playback of an audio track, for example.

Volume adjustment based on user-defined curve

Some embodiments provide a method that receives the addition of a video clip to a composite video project. The video clip has a sequence of video images at a first frame rate and the composite video project has a second frame rate for outputting video images. When the first frame rate does not match the second frame rate but is within a threshold of the second frame rate, the method generates output video images for a particular duration of the composite video project at the second frame rate by using each of the video images of the video clip once during the particular duration. When the first frame rate is not within the threshold, generating output video images for the particular duration of the composite video project at the second frame rate by using at least one of the video images for each output video image over the particular duration.
