Three-Thousand-Year Football History

Create a 30-second popular-science short video about the three-thousand-year evolution of football. Use one ball as the visual throughline. The ball rolls, travels, and transforms from ancient times through different civilizations and eras. The pacing is compact, the visuals are refined, and historical educational filmmaking is combined with artistic transitions. Emphasize the feeling of one ball crossing three thousand years, with concise and powerful narration. Opening: an ancient ball slowly appears from a black background with aged surface texture, then rolls into a Warring States-period Chinese cuju scene. The image becomes ink-wash style, based on <<<image_1_1>>>. Narration: "Long before modern stadiums, people were already chasing a ball." The ball rolls through ancient streets and transforms into balls from different cultures. It passes through medieval courtyards, early modern grass fields, and industrial-era city grounds. Every transition is driven by the ball rolling through the frame. In the modern section, the ball becomes a contemporary football. The scene expands into a large stadium under bright lights, with fast passes, running players, and cheering crowds. The ball flies into the air and the camera follows it in slow motion. Finale: the ball lands at the center of a global field where people from different regions gather. The image should feel grand and epic. Narration: "Today, football connects the world."
