1. An information processing apparatus comprising:
one or more memories storing instructions; and
one or more processors which, when executing the instructions, cause the information processing apparatus to
specify a relationship between a plurality of objects detected in a video, wherein the relationship is a relationship between a first object detected in the video based on an extraction condition and a second object to be gotten on or off by the first object;
determine arrangement of motion trajectories of the plurality of objects, the relationship between which has been specified, while maintaining a relative appearance order in the video and avoiding an overlap of the motion trajectories in a temporal direction; and
generate a summary video of the video based on the arrangement,
wherein the summary video includes the first object and the second object for which the relationship has been specified and does not include the second object for which the relationship has not been specified;
wherein the relationship is specified in a case where a start point or an end point of a motion trajectory of the first object is close to a point indicating a temporary stop of the second object in a temporal and spatial relationship.
