An information insertion method is provided. In the method, background inclination information of a preset entity in a video frame to be inserted with information is acquired. The background inclination information is of a bearing surface of the preset entity in the video frame. At least one piece of foreground inclination information corresponding to at least one piece of multimedia information is acquired. An inclination difference between the background inclination information and each of the at least one piece of foreground inclination information is acquired, to obtain at least one piece of inclination difference information. Target multimedia information that meets an inclination difference condition is determined from the at least one piece of multimedia information according to the at least one piece of inclination difference information. The target multimedia information is inserted onto the bearing surface of the preset entity of the video frame to obtain a target video frame.
