后院学骑自行车

生成一段20秒、16:9的电影感家庭场景，地点是阳光明媚的郊区后院。一位体贴的父亲在平坦且安全的草地上教年幼的儿子骑自行车。开头，父亲帮孩子调整头盔并讲解如何保持平衡；随后他扶着自行车座椅，男孩小心翼翼地蹬车。父亲逐渐松手，男孩独自骑行一小段距离，父亲在旁边慢跑并不断鼓励。结尾，男孩安全停下，与父亲自豪地击掌并拥抱。采用自然的午后光线、温暖色彩、真实的人体动作、清晰的面部表情、轻柔的手持摄影，中景与特写交替，营造快乐而安心的家庭氛围。整个视频中保持后院、自行车、服装和人物外观一致。不要文字、标志、字幕、源视频或音频输入；仅生成视觉序列。

【English Prompt】
Create a 20-second, 16:9 cinematic family scene in a sunny suburban backyard. A caring father teaches his young son to ride a bicycle on a safe, flat patch of grass. Begin with the father adjusting the child’s helmet and explaining how to balance, then show him holding the bicycle seat as the boy pedals hesitantly. Gradually let go so the boy rides independently for a short distance, while the father jogs alongside with encouragement. End with the boy stopping safely and sharing a proud high-five and hug with his father. Use natural afternoon light, warm colors, realistic human movement, clear facial expressions, gentle handheld camera motion, medium shots and close-ups, and a joyful, reassuring family atmosphere. Keep the backyard, bicycle, clothing, and character appearance consistent throughout. No text, logos, subtitles, source video, or audio input; generate the visual sequence only.
