In some implementations the modification to the audio component or the video component may be limited to a single shot or a single scene. This might be useful where, for example, video frames on either side of a shot or scene boundary may differ significantly from the video frames within a single shot or scene. Furthermore, post-production editing of a media presentation may result in transitions between different audio and/or video frames at shot or scene boundaries. Thus, desynchronization between the audio component and the video component may be limited to a shot or scene. In such implementations, the modification may similarly extend to the shot or scene, for example delaying or advancing all audio within a shot or scene by a fixed amount of time.
