Abstract

The invention discloses a video clip positioning method and device, computer equipment and a storage medium, and belongs to the technical field of video processing. The method includes: obtaining a plurality of video frame features of a target video and text features of a target text through a video recognition model; and determining a candidate fragment which can be matched with the target text,finely dividing the candidate fragment based on the matching degree of the video frame in the candidate fragment and the target text to obtain a plurality of sub-fragments, and taking the sub-fragmentwhich has the highest matching degree with the target text as the target video fragment. Such feature matching by multiple times, the obtained candidate fragments are divided again, the mode of the target video clip is determined; therefore, the video recognition model does not need to learn the boundary characteristics of the target video clip, the sample video does not need to be accurately labeled during model training, the training period of the video recognition model is shortened, and the problem of low model output result accuracy caused by inaccurate sample video labeling is avoided.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video clip positioning method, device, computer equipment and storage medium. Background technique [0002] With the popularization of video applications, more and more videos appear on the Internet. When users want to watch a video clip in the video, they can search the video based on a piece of text information that can describe the video clip, so as to find the video they want. Watched video clips. [0003] At present, when locating a video clip based on a piece of text information, the text information and video need to be input into a video recognition model, and the video recognition model outputs a video clip that can match the text information based on the learned boundary features of the video clip. This video recognition model needs to be trained through a large number of sample videos before practical application. In these sample videos, it is neces...
