Abstract

The invention discloses a method for extracting a wonderful shot through a shot playback feature. The method comprises the steps of collecting a video, inputting a video signal and analyzing the video signal; determining a playback shot, carrying out frame comparison on the video starting from a first frame, determining the playback shot and determining start and termination of the playback shot; and clipping the video and clipping the video between the start and termination of the playback shot as a wonderful video; and releasing the video and releasing the clipped wonderful video segment to Internet media. According to the method, through full utilization of the feature that the wonderful shot in the video usually is expressed in a slow shot playback mode, the wonderful shot is automatically extracted through a method of obtaining the start frame and termination frame of the slow shot and is released to the Internet media, abundant content is provided for the Internet media, and the content production efficiency is improved.

Description

technical field [0001] The present invention relates to video processing technology, in particular to a method and system for extracting wonderful shots through shot playback features. Background technique [0002] For now, in the era of converged media, radio and television media and Internet media go hand in hand and complement each other.
