An information processing apparatus, including circuitry configured to transmit a start instruction to a first camera apparatus and a second camera apparatus.　The start instruction causes the first camera apparatus to start incrementing a first counter and the second camera apparatus to start incrementing a second counter for a video recording time period.　The circuitry receives, from the first camera apparatus, a first recording-start frame identifier that indicates a value of the first counter and a second recording-end frame identifier that indicates the value of the second counter.　The circuitry receives, from the second camera apparatus, a first recording-start frame identifier that identifies a value of the second counter and a second recording-end frame identifier that identifies the value of the second counter.
