The present invention relates to a video processing apparatus, method, and system. In particular, in accordance with one embodiment, high-speed video is divided into at least two sub-videos having a frame rate lower than that of the input video, during which metadata for synchronization of the two sub-videos which corresponds to frames of each sub-video is generated, and inserted into the respective sub-videos for video processing in parallel. During the parallel processing of the sub-videos, the system monitors and controls the synchronization of the process and, upon completion of the sub-video processing, use the metadata to re-assemble the sub-videos into one high-speed video stream for output, the output video having the same frame rate as the received input video stream.
