Abstract
A method of shortening a video includes: determining shortened key frames by selecting one key frame for every preset time interval of a time line of the video or for every preset position interval of a camera which captures the video, from among original key frames of the video; determining event key frames from which an event is detected, from among the original key frames; determining event-preserved key frames using the shortened key frames and the event key frames; and generating a shortened video using the event-preserved key frames.
