Abstract

The embodiment of the invention discloses a subtitle generation method and device, a caption-based video retrieval method and device, and electronic equipment. A specific embodiment of the method comprises the steps of extracting audio data from video data of a target video; performing voice recognition on the audio data, and generating subtitle data according to a voice recognition result; and combining the subtitle data with the video data of the target video to generate video data of the target video containing the subtitles. The subtitles corresponding to the audio data of the target videoare generated through the video editor, and the subtitles are combined with the video data. On one hand, the video caption generation cost can be reduced, and on the other hand, the video caption generation speed can be increased.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to a subtitle generation, subtitle-based video retrieval method, device and electronic equipment. Background technique [0002] Subtitles refer to the explanatory text that appears on the video playback interface when the video is playing, and may contain dialogue, captions, or other information. Subtitles help viewers understand what a program is about. Usually subtitles are post-produced after the video program is completed.
