Micro video course making system and method

Abstract

The invention discloses a micro video course making system which is used for recording teaching blackboard writing demonstration and phonetic explanation. The micro video course making system comprises a blackboard-writing tool, a recording controller, an interface recorder, a voice recorder, a clock synchronizer and a file flow manager. The blackboard-writing tool is used for providing an input interface for user operation. The recording controller is used for receiving and displaying the user operation in a screen in real time and meanwhile controlling the screen intercepting time and parameter. The interface recorder intercepts the user operation and / or program operation state in the screen in the teaching blackboard writing demonstration process according to the set parameter and obtains image samples. The voice recorder is used for obtaining audio samples generated in the phonetic explanation process. The clock synchronizer is used for keeping time synchronization of the image sample and the audio sample. The file flow manager is used for generating video data and audio data and thus generating video / audio files for micro video course teaching. The making system is high in integration degree and capable of being operated by a single person, and videos and the audios are synchronized. The invention further discloses a micro video course making method.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a micro-video course production system and a production method thereof. Background technique [0002] With the development of streaming media technology and the rise of video websites, micro-videos with low production costs, short cycle time, and short playback time (as short as 30 seconds and as long as 20 minutes) have become a powerful new carrier for communication. In the field of education, some teachers have begun to try to make their own micro-video courses in this form for students to watch before class and review after class; Learning videos with different duration definitions provide a wide range of online learning spaces and resources for users who do not have a long time to study. [0003] Existing micro-video course production solutions include large-scale course video recording systems and screen recording software, but each has limitations. Among...

AI Technical Summary

Problems solved by technology

Among them, the large-scale course recording system requires the purchase of additional equipment and the participation of recording personnel, and the sound collection of teachers and students and the poor recording effect of projectors due to strobes are not convenient for teachers to use in daily teaching; although the current screen recording software It can be produced at any time without the assistance of recording personnel, and the current screen recording software does not provide professional teaching blackboard writing and presentation tools

[0004] In order to overcome the defects of low equipment integration, inconvenient operation alone and lack of blackboard writing and demonstration tools in the prior art, a micro-video course production system and its production method are proposed
