Abstract: Implementations of the present specification provide a video retrieval method and apparatus. In the method, a video frame in a video to be matched is obtained; an image feature and a text feature are extracted from the video frame; the image feature and the text feature are fused based on a center variable used to represent a cluster center to obtain a fused feature, where the center variable is used to associate features of different modes of a same video; and video retrieval is performed in a video database based on the fused feature to determine a video in the video database that matches the video to be matched, where a plurality of videos and video features corresponding to the plurality of videos are stored in the video database.
