The invention discloses a video optimization processing system comprising: an initial image library used for storing original images; a video jitter detection module which is used for detecting the original image and judging whether the original image is a jitter image or not; a video jitter correction module which is used for correcting the jitter image to obtain a corrected image; a image playing library which is used for storing the jitter-free image and the corrected image, wherein the video jitter detection module is connected with the initial image library, the image playing library andthe video jitter correction module, and the video jitter correction module is connected with the initial image library and the image playing library. The invention further provides a video optimization processing system, processing terminal equipment and a storage medium. According to the method, through division of the sub-region blocks, jitter elimination and motion compensation are carried outon each frame of image by taking the sub-region blocks as units, so that the restoration efficiency and quality of the image with jitter blurring are ensured, and the video playing rate is ensured.
