夜空烟花慢镜头

生成一段20秒、16:9画幅的电影感视频。夜晚，深色开阔天空充满画面，绚丽烟花升空后绽放成层叠的红色、金色、蓝色和白色花束。以流畅的慢动作捕捉爆炸过程，展现火花扩散、拖曳并在淡淡烟雾中逐渐消散。让烟花的大小和绽放时机有所变化，形成自然的庆典节奏。使用稳定的广角视角、高对比度、真实的光线照明、细致发光粒子和精致电影质感。不要出现人物、文字、标志或依赖音频的动作。

【English Prompt】
Generate a 20-second cinematic video in a 16:9 aspect ratio. At night, a dark open sky fills the frame as brilliant fireworks launch upward and burst into layered blooms of red, gold, blue, and white. Capture the explosions in smooth slow motion, showing sparks expanding, trailing, and fading through faint smoke. Vary the burst sizes and timing for a natural celebratory rhythm. Keep the camera steady with a wide view, high contrast, realistic light illumination, detailed glowing particles, and a polished cinematic look. No people, text, logos, or audio-dependent action.
