1. A video special effect processing method, comprising:
detecting music played along with a video during a process of playing the video, wherein the video comprises a target object;
acquiring a video frame image to be played in the video when the music is detected to be played at a preset rhythm;
performing special effect processing on the target object in the video frame image to obtain a special effect processed video frame image, comprising:
determining a special effect processing mode corresponding to the preset rhythm according to the preset rhythm; and
performing special effect processing on the target object in the video frame image according to the special effect processing mode to obtain a special effect processed video frame image, wherein the rest of the video frame image other than the target object in the video frame image remains unchanged; and
displaying and playing the special effect processed video frame image;
wherein:
the special effect processing mode is zoom-out processing or zoom-in processing, the zoom-out processing is to only magnify the target object in the video frame image to realize a zooming-out video effect, and the zoom-in processing is to only reduce the target object in the video frame image to realize a zooming-in video effect;
the zoom-out processing specifically is: in the video frame image, magnifying the target object to realize the zoom-out video effect until the target object is magnified to a maximum threshold value, and performing a shaking function on a video picture corresponding to the target object after being magnified to the maximum threshold value; and
the zoom-in processing specifically is: in the video frame image, reducing the target object to realize the zoom-in video effect until the target object is reduced to a minimum threshold value, and performing a shaking function on a video picture corresponding to the target object after being reduced to the minimum threshold value.
