Abstract: Spherical video content may define visual content viewable from a point of view as a function of progress through the spherical video content. The spherical video content may include an event of interest that occurs within an event moment and within an event extent of the visual content. The spherical video content may be presented on a display. Display fields of view defining extents of the visual content viewable from the point of view may be determined. The display fields of view may define a display extent of the visual content at the event moment. Whether the event extent is located within the display extent during the presentation of the spherical video content at the event moment may be determined. Responsive to a determination that the event extent is located outside the display extent, visual/audio effect may be applied to the presentation of the spherical video content.

Abstract: Interaction information may be received. The interaction information may indicate a user's spatial selections of video content as a function of progress through the video content. The spatial selections of the video content may include viewing directions of the video content selected by the user as the function of progress through the video content. Related video content may be identified based on the spatial selections of the video content. Related video content may be offered to the user.

Abstract: Interaction information may be received. The interaction information may indicate users' spatial selections of the video content as a function of progress through the video content. The video content may have a progress length. The spatial selections of the video content may include viewing directions of the video content selected by the users as the function of progress through the video content. Aggregate spatial selections of the video content may be determined at individual points in the progress length. Aggregate spatial selections may include an aggregation of the viewing directions selected by the users at the individual points. Directions of view for the video content may be determined based on the aggregate spatial selections of the video content. The socially built view of video content may be generated based on the directions of view for the video content.
