What it does

Promo Editor is an agent skill from kangarooking/promo-creator-skills. 使用 HyperFrames 将所有素材按分镜时间码串联，添加文字层、动画、转场，渲染成完整宣传片 MP4。这是整个流程的核心渲染引擎。当素材确认后自动进入。

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Motion graphics. It works with HeyGen. The repository describes itself as: 产品宣传视频创作 Skills：从产品判断、分镜、素材、HyperFrames 剪辑到 BGM 设计的完整 Agent 工作流. The licence is MIT.

When your agent uses it

  • Tasks that involve Motion graphics

Example prompts

  • “/promo-editor”

Requirements

  • Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. 每个可见元素必须有唯一 id + class="clip" + data-start + data-duration + data-track-index
  2. track-index：0 = 主画面层，1 = 文字层，2 = 装饰层，5 = 转场层
  3. 动画用 GSAP timeline，必须 paused: true
  4. 分辨率：1920×1080，不能变
  5. 不能用 repeat: -1（改为有限次数）
  6. 字体用 Google Fonts（Inter / Playfair Display / JetBrains Mono / Noto Sans SC）

What it can do on your machine

Read from SKILL.md and the folder at commit 2d23af9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • fonts.googleapis.com
    • cdn.jsdelivr.net

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Promo Editor loads about 2.3k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 199 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

静态图片动态化

网络搜索的截图（Pack B）不是视频，必须添加动画：

js
// Ken Burns（默认）
tl.from("#static", { scale: 1.08, duration: 5, ease: "none" }, start);

// 平移视差
tl.from("#static", { x: 30, duration: 5, ease: "none" }, start);

// 渐入 + 微缩放
tl.from("#static", { opacity: 0, scale: .95, duration: .6, ease: "power2.out" }, start);

规则：静态图片展示 3-8 秒，必须有至少一个微动画。

渲染

bash
# 快速预览
npx hyperframes render --quality draft --output promo-draft.mp4

# 最终高质量
npx hyperframes render --quality high --gpu --output final/promo.mp4

# ProRes（导入专业软件）
npx hyperframes render --format mov --output final/promo.mov

质量检查

渲染前逐项确认：

P0（致命）
  • 总时长与 EDL 一致
  • 无素材文件 404
  • 无黑帧 / 空帧 / 闪帧
  • 首帧不是黑屏
  • 末帧有渐黑收尾
  • 所有文字可读（不被图片遮挡）
P1（重要）
  • 无连续 2 个相同转场
  • 静态图片都有微动画
  • 每个 Shot 动效与 storyboard 一致
  • 风格统一（无混搭）
P2（优化）
  • 动画节奏感好（不过快不过慢）
  • 缓动函数自然（无 linear）
  • 留白充足

工作流

  1. 读取 02-storyboard.md + 03-asset-plan.md
  2. 检查 assets/pack-a/ 和 assets/pack-b/ 素材完整性
  3. 生成编辑决策表 04-edl.md
  4. [PAUSE] 等用户确认时间线
  5. 写 master-edit.html（HyperFrames 主合成文件）
  6. 逐 Shot 编写 HTML + GSAP 动画
  7. npx hyperframes preview 预览
  8. npx hyperframes render 渲染
  9. [PAUSE] 用户预览确认成片
