Research of a Method of Creating a Video File Based on Metadata

Abstract

This article brief introduced a method for using Speech Search metadata to create a video file in which user can extract subtitles automatically and search for spoken words in a video. Create temporal metadata through transcribed speech using the XMP metadata transcript technique with Premiere pro. The transcript can be edited to ensure the correctness of the text content; Write an After Effects script expression to show the transcript as subtitle in the screen. Change the layer markers to navigation cue points and export the video file. Practice has been proved that expertly mastered this method will help produce high efficiency and high quality movies.
