Abstract

The invention discloses a method and a device for adjusting subtitles in a video and also a server, relating to the technical field of computers. The method comprises the following steps: acquiring avideo file to be played and a subtitle file of the video file; performing voice activity detection on an audio stream of the video file to obtain an effective audio interval; combining a subtitle interval of the subtitle file and the audio interval in a time domain; according to the combined interval, shifting the subtitle interval which exceeds the audio interval in the time domain into the corresponding audio interval to obtain an adjusted reference interval; determining subtitles in a reference interval as adjusted subtitles. The accuracy of subtitle adjustment in a video can be improved byapplying the embodiment of the present disclosure.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular, to a method, device and server for adjusting subtitles in a video. Background technique [0002] In the current video playback software, in order for the user to better understand the audio content in the video, the function of external subtitles can usually be provided. For example, when playing a video in a foreign language, it is often necessary to add translated subtitle files. [0003] Generally, after loading the subtitles into the video, in order to avoid the out-of-sync between the subtitles and the sound in the video, it is also necessary to adjust the subtitles in the video. [0004] However, in the prior art, the adjusted subtitle has the problem of low accuracy. Contents of the invention [0005] The embodiments of the present disclosure provide a method and device for adjusting subtitles in a video to solve the problem in the prior ...
