A video analysis system of swing motion includes an imaging unit that images video of swing motion, an impact detection unit that detects impact, a control unit and a video display unit. The control unit has (a) a function of receiving the video of the swing motion from the imaging unit; (b) a function of receiving an impact detection signal from the impact detection unit; (c) a function of recording the video of swing motion received from the imaging unit into the control unit; and (d) a function of, when the control unit records into the control unit the video of the swing motion received from the imaging unit, determining an impact time based on the impact detection signal received from the impact detection unit, to record images of the swing motion for a predetermined time period containing the impact time.
