Abstract
(EN)
The present application belongs to the technical field of audio and video, and relates to a method and device for obtaining a video clip, a server, and a storage medium. The method comprises: when obtaining a clip in live stream video data of a performance live stream room, using audio data from the live stream video data and audio data of an original performer to determine a target timepoint pair of the live stream video data; and obtaining a target video clip according to a start timepoint and an end timepoint in the target timepoint pair. The present application is used to capture a more complete video clip.
