Automatic video editing method and system, terminal and storage medium

Abstract

The invention discloses an automatic video editing method and system, a terminal and a storage medium. The method comprises the following steps: acquiring a key frame of a video to be edited, carrying out self-marking on the key frame by adopting an image comparison algorithm, and generating an unsupervised vector representation of the key frame; corpus information of a to-be-edited video is acquired, and unsupervised vector representation of the corpus information is acquired by adopting a text comparison algorithm; segmenting the video to be edited according to the key frames, and generating video clips corresponding to the number of the key frames; and calculating the similarity of adjacent video clips according to the unsupervised vector representation of the key frame and the unsupervised vector representation of the corpus information, merging the adjacent video clips with the similarity greater than a set similarity threshold, and generating a video editing result of the to-be-edited video. According to the embodiment of the invention, the image and text information is utilized, manual data annotation is avoided, automatic video editing is realized, and the video editing efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to an automatic video editing method, system, terminal and storage medium. Background technique [0002] With the development of 4G network, short video technology has developed vigorously. With the emergence of a large number of video apps such as Douyin, Kuaishou, and Station B, the number of videos has increased exponentially. Although video is more intuitive than text and pictures, it takes a lot of time to watch videos. For a very long video, valuable or user-interested segments often only account for a portion of the total length of the video, so the demand for video clips is also increasing day by day. [0003] Video editing in the prior art usually needs to rely on human resources, which is not only expensive, but also has low video editing efficiency, which hinders the development of short video technology to a certain extent. SUMMARY OF THE INVENTION [000...
