Abstract

The invention provides a video compression method. The video compression method comprises the steps that each video frame and a time point corresponding to each video frame are extracted from videos; the video frames are compared step by step so as to obtain multiple types of video frames provided with the same static images; the current types of video frames provided with the same static images are segmented to obtain static images and multiple dynamic images, wherein the number of the dynamic images is equal to the number of the current types of video frames; the time points of the current types of video frames correspond to the multiple dynamic images in a one-to-one mode; the static images and the multiple dynamic images are compressed to obtain compressed files. In the mode, the compression degree and compression speed can be improved by the adoption of the video compression method.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a video compression method. Background technique [0002] With the development of mobile devices such as smartphones, tablet computers and e-readers, the use of multimedia data on mobile terminals is becoming more and more widespread. [0003] Since the network environment where the mobile terminal is located is variable and complex, the available bandwidth is easily limited, so when the mobile terminal needs to download or upload a video file with a large amount of data to the network side, it usually needs to compress the video file. [0004] The current video compression method is to compress the entire content of the video. When the video capacity is relatively large, the compression speed is slow, and the size of the compressed video file is often difficult to meet the user's needs. Contents of the invention [0005] The technical problem mainly solved by the present...
