Abstract
(EN)
Disclosed in the embodiments of the present application are a video data processing method and device, and a storage medium. The method comprises: in response to a trigger operation for a target video, determining a target object from a key video frame of the target video, and acquiring multimedia information associated with the target object; determining, on the basis of the position information of a target pixel point of the target object in the key video frame, a trajectory acquisition request corresponding to the target pixel point; acquiring target trajectory information associated with the position information of the target pixel point in the key video frame on the basis of the trajectory acquisition request; and when the next video frame of the key video frame is played, displaying the multimedia information on the basis of the position information of the target pixel point in the next video frame of the key video frame in the target trajectory information.
