  • Patent number: 11770497
    Abstract: A method, apparatus, and a non-transitory computer-readable storage medium for processing a video are provided. A terminal determines a subject region of a video frame in a video and a background region. A target object is located in the subject region. The background region is a region of the video frame other than the subject region. The terminal overlays the subject region in at least one of a first video frame having the target object on at least one of a second video frame having the target object and generates a special effect frame including at least two subject regions in each of which the target object is located.
