1. A method for summarizing a video comprising:
obtaining the video;
extracting a plurality of features describing the events from the video, wherein each event is defined by a single timestamp in the video;
determining quantitative values for each event by evaluating the plurality of features according to at least one evaluation criterion;
assigning one or more of the determined quantitative values to the events;
generating segments of the video by:
determining segment lengths based on representing the quantitative values of events in the video with a distribution having a profile over a video length, wherein the segment length is a function of the distribution with respect to time and the distribution profile is based on an underlying video context or respective event types; and
compiling a summary video using scores for the segments by assessing aggregated quantitative values for video times.
