Apparatus and associated methods relate to dividing a multimedia stream into sections segmented as a function of a characteristic of the multimedia stream, choosing from the segmented multimedia stream sections a highlight multimedia segment selected as a function of the segmented multimedia stream section content, and automatically providing collaboration access to a summarized multimedia stream constructed as a function of the highlight multimedia segment. In an illustrative example, the multimedia stream may be video. The video may be divided into segmented sections as a function of a characteristic of the video. The video characteristic may be, for example, a video temporal characteristic. In some examples, the highlight multimedia segment may be selected from the sections based on video segment content. A video highlight summary may be automatically created based on one or more highlight segments. Various examples may advantageously provide multi-user video montage creation based on the automatic highlight summaries.
