Video abstraction is a short version of the original video, and it is used to deliver the summary or the highlight of video contents as quickly as possible. According to the objectives of the video abstraction, the set of shots constituting the abstraction should be different. This paper presents an authoring tool that could automatically generate various kinds of video abstractions according to the objectives of the abstraction, and allows the author to easily edit the resulting abstraction manually. In the proposed automatic video abstraction algorithm, a simulated annealing algorithm is used to select the set of shots that simultaneously satisfies several constraints, such as well-distributed, well-fitting, high-activities, and non-duplicated (or concise), as much as possible. This set of shots could be used as a final video abstraction, or a candidate of the video abstraction that the author could replace with just a drag-and-drop of the key frame of the selected shot on the time-line of target video abstraction.
