Cinematic Motion Blur Typography Portrait

Generate a cinematic portrait image with dynamic motion blur based on a specific theme: The subject occupies the main visual weight with a quiet side profile or half-body silhouette, keeping a few recognizable details on the face edges. The body and hair are stretched into long horizontal motion blur to one side, like light ribbons passing through the subject and gradually blending into the background, making the person look as if they are being carried away by speed, memory, or information flow. The background is a vast, clear, high-brightness, and soft air field without complex scenes. Colors are extracted from the textures, emotions, and narrative temperature of the theme itself, maintaining the relationship between a large area of bright and calm base color, deep subject shadows, a small amount of high-saturation glowing highlights, and clean tonal gradations, creating a dreamy yet clean tension between warm and cold, avoiding muddiness, staleness, or ashen tones. The light is softly diffused, the focus is slightly loose, with slight film grain and lens dispersion at the edges, but the overall feel remains ventilated, transparent, and modern. The information density is very low, leaving a large amount of empty space for the sense of speed to breathe. Typography is used as part of the visual structure with a pure white modern sans-serif font; the core word is placed below the subject or near the center of gravity in a very large font size, while short descriptions use smaller font sizes, compact line spacing, and a centered rhythm. All text appears as a clear interface layer superimposed on the light mist, grounding the visual hierarchy without disrupting the flow of the soft-focus image.\n\nSubject: {argument name="subject" default="Dilraba walking briskly at the airport"}\n\nAspect Ratio: {argument name="aspect ratio" default="3:4"}

围绕具体主题内容生成一张具有电影感的动态拖影肖像画面：主体以安静的侧面轮廓或半身剪影占据主要视觉重量，面部边缘保持少量可辨识细节，身体和头发向一侧被拉成长距离水平运动模糊，拖影像光带一样穿过主体并逐渐融入背景，使人物像正在被速度、记忆或信息流带走。背景是一整片高明度、清透、柔和的空气场，不做复杂场景，色彩从主题自身的材质、情绪和叙事温度中提取，保留大面积明亮冷静底色、较深主体暗部、少量高饱和发光强调色与干净色阶之间的关系，形成梦幻而清洁的冷暖张力，避免浑浊、陈旧和烟灰感。光线柔软扩散，焦点略松，边缘有轻微胶片颗粒和镜头晕散，但整体仍然通风、透明、现代。画面信息密度很低，留出大量空域让速度感呼吸；文字作为视觉结构的一部分使用纯白现代无衬线字体，核心词用极大字号放在主体下方或画面重心附近，短句说明使用较小字号、紧凑行距和居中节奏，所有文字像叠在光雾上的清晰界面层，既压住画面层级，又不破坏柔焦影像的流动感。\n\n本次主题：{argument name="主题" default="在机场快步走的迪丽热巴"}\n\n比例{argument name="比例" default="3:4"}
