Computer-based editing methods and systems for defining and generating transitions between video clips in a video presentation. Transition regions are defined at one or both ends of a video clip such that the transition region remains defined on the first video clip until the transition region is edited or deleted by a user. Making the transition region a property of the clip upon which the transition region is defined, and retaining that property while the clip is manipulated within a timeline of a video editing system reduces ambiguity as to how transitions are to be treated in the editing process. It also helps reduce loss of original video material associated with transition regions during the editing process.
