Opus 5.5 Draws a BaoCut Promo Video Frame by Frame

The takeaway is that coding agents can double as animation pipelines: deterministic Canvas rendering plus a beat table gives Opus 5.5 a feedback loop where keyframe stills can be self-checked before a full render. Developers who want AI-made promo assets without a motion-design tool can adapt this prompt structure, grounding the model in real code and specs to avoid hallucinated features. It also shows Claude Code reusing local CLIs like Codex without API keys.
Baoyu (dotey) used Claude Code with Opus 5.5 to produce a 62.
5-second, 1920×1080 @30fps promotional video for his BaoCut video editor.The prompt directed the model to first read the project's prototypes, brand kit and app icon code, then render every frame deterministically with JavaScript and Canvas.
The workflow split output into lib, characters, editor, story and audio files, used a beat table to sync visuals with a 120 BPM synth soundtrack, and exported an MP4 via render.
mjs.He applied the same JS + Canvas technique earlier to generate a vector-style app icon after finding image generators like ChatGPT produced non-vector results.

做完 AppIcon 再让 Opus 5.5 为 baocut.app 做了一个宣传视频 --- 参考提示词(在项目内用 Claude Code 执行) --- 为 BaoCut 做一支 62.5 秒、1920×1080 @30fps 、英文的产品介绍视频，风格是手绘卡通加魔法少女式的夸张特效，要可爱、炫酷、适合转发。 先读 designs/baocut 原型和 apps/baocut 拿真实的编辑器、Brand kit、Elements、Agent 面板布局；读 scripts/dev/app-icon 拿图标：星芒加播放头、三条彩色轨道。模板数、贴纸数、声波数、本地模型名、支持的 Agent CLI 都以代码为准；翻译不能写成本地功能。 要突出这些特色：自动字幕、翻译、AI 配音、剪口癖、品牌套件、模板、动态贴纸与声波、智能裁剪、本地文生图、全部模型在本机跑、内置 Agent 复用本机的 Claude Code / Codex 等 CLI 而不需要 API key。 叙事： 图标拆开，星芒和播放头变成超级可爱的小机器人 Bao 手里的魔法棒，三条轨道拉长成时间轴，底板变成预览。Bao 给猫咪女主播 Mimi 的视频连施九段咒语（Subtitlio!、Translato!……），她说话时的 meow / purrr / nya~ 口癖变成小老鼠，被 Bao 一棒一个敲掉。 接着玻璃罩落下，表示「全部在你的 Mac 上跑」。最后一切倒带，Bao 敲碎 API key 输入框，一句话交给 Agent 全部做完，再把魔法棒插回图标。关键动作配震屏、冲击波和白闪。 第 0 帧是「Edit videos like MAGIC」封面，Bao 举着魔法棒指向一张已经变好的猫咖成片卡，四周是九个功能标签。 实现： 放在 scripts/dev/robot-video/，分成 lib / 角色 / 编辑器 / 故事 / 音频几个文件，用 canvas 确定性逐帧绘制。 节拍表 T 和冲击点表 IMPACTS 同时驱动画面与音效，配乐是 120 BPM 的合成木琴律动。 render.mjs 导出 mp4，index.html 做预览。 每段抽关键帧拼图自查后再整片渲染。
