The invention discloses an automatic detection method of jitter of a video. The automatic detection method comprises the following steps of: a first step, selecting feature points from a video picture; a second step, tracing and matching the feature points in an adjacent frame; a third step, removing abnormal points of the feature points to obtain an inter-frame motion vector; a fourth step, extracting a video jitter frequency and video jitter amplitude features; a fifth step, extracting histogram features of an inter-frame light stream vector; and a sixth step, judging the video jitter degree through a classifier. According to the automatic detection method, any prior knowledge is not needed while judging whether the video has jitter and the automatic detection method has the advantage of a higher accuracy rate.
