Video metadata labeling method for film and television materials

The invention discloses a video metadata labeling method for film and television materials, and belongs to the technical field of digital film making. The method comprises the steps of reading and preprocessing a video, obtaining a video frame sequence, determining whether a clapper board exists or not, reading the video frame sequence frame by frame, identifying tag data items, and automatically extracting semantic information. Semantic information is mapped to semantic label data items and stored in semantic label fields, redundant data items are cleared and removed, associated storage is carried out, and automatic labeling of video semantic labels is achieved; and reading the video metadata, retaining necessary video metadata tag fields, and adding semantic tag fields to realize construction of the video metadata of the film and television materials. By analyzing and processing the film and television material, automatically extracting the semantic information of the frame picture, automatically labeling t
