公园长椅上的专注短信

生成一段20秒、16:9的电影感视频。一名性别中性的青少年独自坐在宁静的公共公园长椅上，完全专注于用智能手机发短信，没有察觉周围活动。先用中远景展示树木、步道、柔和日光和背景中若隐若现的行人，然后平缓地推近到中景和特写，表现青少年专注的面部、打字的双手以及发光的手机屏幕，但不要显示可读的私人消息。保持动作自然且符合年龄：拇指轻微移动、偶尔眨眼、略微调整坐姿，不与他人互动。近景保持真实的皮肤、衣料、树叶和光线，使用浅景深；镜头运动稳定流畅，整体为安静的观察式氛围、自然色彩，并保持全程连贯。不要对白、字幕、标志或依赖音频才能理解的动作。

【English Prompt】
Generate a 20-second, 16:9 cinematic video. A gender-neutral teenager sits alone on a park bench in a calm public park, completely absorbed in texting on a smartphone and unaware of the surrounding activity. Show a medium-wide establishing shot with trees, walking paths, soft daylight, and subtle background pedestrians, then make a gradual gentle push-in to medium and close-up views of the teenager’s focused face, hands typing, and the glowing phone screen without readable personal messages. Keep the teenager’s movements natural and age-appropriate: slight thumb motion, occasional blinking, a small posture adjustment, and no interaction with others. Maintain realistic skin, fabric, foliage, and lighting, shallow depth of field on closer shots, stable smooth camera motion, quiet observational mood, natural colors, and coherent continuity throughout. No dialogue, captions, logos, or audio-dependent actions.
