Video generation method, system and equipment based on online education and storage medium

Abstract

The invention provides a video generation method and system based on online education, equipment and a storage medium, and the method comprises the steps: segmenting at least one section of recorded video of the online education into a plurality of video paragraphs according to a preset duration; adding at least one video tag to the video paragraph according to the content information of the videoparagraph; and editing the video paragraphs with the video tags according to a preset first user tag to obtain a video file comprising a plurality of video paragraphs. According to the method, the whole video is segmented into the video segments and the tags are added backwards, so that the whole video is conveniently selected and optimally edited, the watching value of video playback is increased, and the humanized experience is improved.

Description

technical field [0001] The present invention relates to the field of online education, in particular, to a video generation method, system, device and storage medium based on online education. Background technique [0002] At present, the technology of entering virtual classrooms through network connection is quite mature, and various course courses can be recorded in different data types. The easiest way to record the course courses is to record users screen and save it as a video file. Or assemble a self-customized multimedia (html tag, javascript, mp4 / webm, xml data) through various scripting languages ​​to play (such as: BigBlueButton software). However, once such classrooms (a. the number of courses started to increase proportionally and (b. need to dynamically modify various contents in the video file (for example: remove inappropriate comments, individual student audio files failed to record individually) It is necessary to manually take out the file and restore it,...

Problems solved by technology

However, once such classrooms (a. the number of courses started to increase proportionally and (b. need to dynamically modify various contents in the video file (for example: remove inappropriate comments, individual student audio files failed to record individually) It is necessary to manually take out the file and restore it, and do not want the user to see part of the video segment). It is extremely wasteful of computing resources and manpower to use the former method of skimming or the latter method of reassembling through scripting language. Cost

[0003] Usually, in a teaching video, the entire length is at least half an hour to 2 hours, and contains a lot of knowledge points. However, the existing videos lack the function of searching or browsing. Students can only watch from the beginning to the end mechanically. Or fast-forward playback, etc., the utilization efficiency of the teaching video is very low, which results in a fixed use scene of the teaching video, and the single way for students to use the teaching video

Moreover, some teaching videos also include titles, endings, the teacher’s self-introduction or greetings, etc. The value of each video clip in the teaching video is different, and it is difficult for the teaching video to provide students with the best information for each student in a targeted manner. required video clip
