1. An information processing apparatus comprising:
a processor; and
a memory including instructions stored thereon, when, when executed by the processor, cause the information processing apparatus to:
generate a key frame in which parameters representing a position of a virtual viewpoint and an orientation of the virtual viewpoint are associated with time in a period during which image capturing is performed by a plurality of imaging devices, the virtual viewpoint being determined based on a user operation for designating the virtual viewpoint relating to a virtual viewpoint image generated based on a plurality of captured images obtained by image capturing performed by the plurality of imaging devices;
set a playback direction of a plurality of key frames;
generate a list in which key frame information capable of identifying each of a plurality of key frames is arranged based on a playback direction set;
generate virtual viewpoint information representing transition of the virtual viewpoint based on the list; and
determine, in a case where key frame information corresponding to another key frame with which the same time as that associated with a key frame is associated is arranged in the list, arrangement of key frame information corresponding to the key frame in the list based on the key frame and the parameters associated with the other key frame.
