Abstract: A video similarity detection method and apparatus are provided. In the method, a detection apparatus receives a first video, determines a key frame of the first video based on the first video, and determines a similar key frame and a second video, the similar key frame being determined based on the key frame. The second video includes a video in which the similar key frame is located. The method inputs the key frame and the similar key frame to an editing type recognition model to obtain an editing type. The editing type indicates an editing type used for editing between the first video and the second video.
