Video prompt: Vibrant 4K UHD video, 10s, 60fps, loopable, close-up, vertical composition, group of colorful Japanese koi fish (nishikigoi) with red, white, black, and blue patterns. Swimming in serene pond: green lily pads with white flowers, small stone lantern sticking out of water, bamboo plants along bank, cherry blossom trees lining shore. Dynamic actions: The koi fish swim in a tight group, weaving through the lily pads, their bodies twisting and turning in a graceful, synchronized dance; a large red and white koi fish leads the group, swimming faster than the others, then slows down to let the others catch up; one koi fish breaks away from the group, swimming up to the surface of the water to take a breath, then dives back down, joining the group again; the fish swim around the stone lantern, their scales glinting in the sunlight, creating a beautiful, colorful display; a single cherry blossom petal floats on the surface of the water, and a small black and white koi fish swims up to it, nudging it with its nose, then swims away. Lighting: Bright midday sunlight, vibrant colors, high contrast, sharp details on koi fish’s scales and lily pads, no text, no watermark. Style: Vibrant, serene, natural aesthetic. --ar 9:16 (Vertical, 1080x1920, YouTube Shorts Standard)
