A multi-camera system, including a first camera apparatus, and second camera apparatus, and an information processing apparatus. The information processing apparatus includes a communication interface, and processing circuitry that receives a predetermined request from a user while the first camera apparatus captures a first video and the second camera apparatus captures a second video. The processing circuitry, in response to the predetermined request, transmits a first control signal to the first camera apparatus that causes the first camera apparatus to generate a first thumbnail of a frame of the first video, and transmits a second control signal to the second camera apparatus that causes the second camera apparatus to generate a second thumbnail of a frame of the second video. The processing circuitry receives the first thumbnail from the first camera apparatus and the second thumbnail from the second camera apparatus.
