Systems and methods for marking an event of interest within a spherical video segment are provided. The spherical video segment may define visual content viewable from a point of view. User input designating an event of interest within the visual content may be received. The user input may indicate a point in time in the spherical video segment and a viewing angle of the event of interest. Tag information associated with the event of interest may be generated. The tag information may identify the point in time and the viewing angle such that notification of alert information is effectuated based on a determination that the viewing angle, proximate to the point in time during a subsequent presentation of the spherical video segment, is outside a display field of view. The alert information may indicate that the event of interest is located outside the display field of view.
