提示词正文
Claude Code：safe mode，high effort，不加载外部 skill，不引入第三方素材。 输入：我提供的竖屏口播 MP4（唯一影像起点）。 要求： - 原声、原字幕、总时长 100% 不变。 - 说话人缩到右下角圆形画中画，不得遮挡字幕。 - 主画面替换为 light humorous line-art B-roll，讲到什么概念画什么（Python 逐帧或矢量时间轴均可）。 - 按字幕切 ~30 镜头；每个切点检查对齐。 - 输出新文件名 MP4 + 改造计划表（时间段 → 原画面 → 新 B-roll 描述）。 公开说明：源片表演/声音仍来自原视频，不是从零生成。
实现步骤与运行指引
- Claude Code safe mode, high effort; source vertical MP4 only.
- PiP circular speaker; line-art B-roll per concept; ~30 subtitle-aligned shots.
- Verify subtitle boundaries, audio, exact duration; new filename export.

无缝 UI 变形循环（Beat-synced Playwright + FFmpeg）
1440×1440 纯时间 HTML UI 循环：8–12 状态、闭式弹簧、光标驱动、NumPy 对拍、Playwright 子帧 + FFmpeg 运动模糊。
Playwright + FFmpeg60 FPS
#UI Morph#Motion Graphics#Playwright+2
loop ~1 bar × 71:1
Use the full template for a beat-synced UI morph loop rendered from a single HTML scene with Playwright and FFmpeg. Inputs I will provide: 8–12 UI states, one accent color (or monochrome), and a royalty-free track near 120 BPM. Visual rules: - 1440×1440 warm-gray canvas, Geist typography. - ONE continuously morphing shell (never cut into separate layers); content swaps inside with short blur only. - Visible cursor causes EVERY click and drag; drags set values from cursor position while held, release springs from current state. - Restrained springs and camera zooms; NO bounce easing, particles, glow, chrome gradients, mismatched icon weights, dead air, or template SaaS look. Beat map (7 bars): button → loader → check → dynamic island → player play/pause → scrubber drag → overextended volume slider → toggle → liquid tab indicator → self-drawing chart + tooltips → command palette type/filter → Enter → toast → return to starting button. Engine: - Single HTML file; seek(t) computes ALL properties; no CSS transitions, no setInterval, no hidden frame state. - Closed-form spring step responses with superposition for multi-step targets; independent edge springs for tabs/toggles. Render: - Analyze audio in NumPy; start on downbeat; UI clicks on measured peaks. - Playwright: 4 subframes per output frame; FFmpeg tmix → 60fps motion blur. - Before full render: one still per beat; fix off-grid timing and legibility; avoid will-change on camera-scaled nodes; separate in/out text timing; last frame MUST match first (cursor pos + velocity).

制作一段 15 秒的 dynamic motion-design showreel，用于设计师作品集。请尽情发挥（go all out）：自主决定视觉系统、字体排印、转场语言和配乐（可用 Web Audio 生成或我提供的音轨）。 约束： - 前两秒必须有强钩子；全程避免超过 0.4s 的静止。 - 结尾 1 秒留 memorable logo/type moment。 - 优先用代码渲染（Canvas/SVG/HTML），单文件或可复现渲染脚本。 - 先给 480p 预览 + 分镜表（时间码 + 画面描述），我确认后再出 1080p 母版。

make a modern slick and punchy video for a modern startup that works on inference. I will supply: product name, logo SVG/PNG, 3 UI screenshots, one-sentence value prop, brand colors. Your tasks: 1. Turn this into hook (3s) → proof (latency/cost diagram, real UI) → payoff (CTA) for ~25s. 2. Do not invent customer logos, benchmarks, or compliance claims. 3. Render with Remotion or deterministic HTML/CSS animation; deliver MP4 + editable project if applicable. 4. Low-res preview first; list copy that legal must verify.
