producing-video

producing-video is a skill for Claude Code from sugarforever/01coder-agent-skills. It costs 175 tokens per session (3,655 once invoked), scanned A, original, MIT.

A video-production workflow that combines a finished voiceover audio file and an SRT subtitle file into a narration-synced MP4. SRT is a subtitle format containing text and the start and end time for each caption.

In plain words
What is it for?
Use it to create videos from an MP3, WAV, or M4A voiceover plus an SRT file. It builds timed scenes with HyperFrames, adds the audio during rendering, checks the result, and outputs the finished MP4.
Why use it?
It uses the supplied audio and subtitle timings as the source of truth, so scenes follow the narration without manually aligning them. It also avoids treating voice generation or transcription as part of this workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

producing-video scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/srt-cues.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Producing-Video · 音频 + 字幕 → 成片

把"用户已经录好的口播音频 + SRT 字幕"做成一条画面跟着声音走的 MP4。用 HyperFrames(HTML 即视频)出片。

铁律:音频和 SRT 是唯一事实源。 画面的内容来自 SRT,画面的时间轴来自 SRT 的 cue 时间戳,音频作为一个 <audio> clip 直接挂进合成里、渲染时自动合流 —— 没有"先出视频再合音频"这一步

分工(很重要)

做什么
用户 写稿 → 录音/合成音频 → 生成 SRT → 把 audio.mp3 + audio.srt 交给你
本 skill(你) 选 frame/品牌 → 按 SRT 搭 HyperFrames 合成 → 校对 → 渲染成片

用户指望你生成配音(那是上游)。如果用户还没有音频、问的是"怎么配音",那不是本 skill —— TTS / 声音克隆是另一条线(见下方"超出范围")。

依赖检查(pre-flight)

npx hyperframes doctor      # 需要 Node ≥ 22 · FFmpeg · Chrome

需要 hyperframes / hyperframes-cli 两个 skill 在场(编写合成 + 跑 CLI)。缺了就让用户 npx hyperframes skills 安装后重来。

确认用户给了两个文件:音频(mp3/wav/m4a)+ SRT。只给音频没给 SRT → 本 skill 需要 SRT 拿时间轴;可让用户补 SRT(很多录音工具/剪辑软件能导出),不要默认去跑 Whisper 转写(用户没给 SRT 往往是有意的,先问)。


工作流

Step 1 · 选 frame / 品牌

画面的风格 = 一个 frame.md / visual-style / 既有系列品牌。三种来源,按情况选:

  1. 延续系列品牌(推荐用于日更/系列)。如果这期属于一个已有系列(如"AI 早读"),去翻该系列的封面/历史成片,沿用同一套 token(颜色、字体、栅格、页眉页脚),让视频和封面一脉相承。
  2. HyperFrames frame.md 模板。用户可能直接点名,例如 creative-mode / biennale-yellow / cobalt-grid。取 token:
    • curl -sSL https://www.hyperframes.dev/design/<slug>.md (站点是 JS 渲染,多半取不到正文);
    • 更靠谱:在本机 open-design 仓库里找 design-templates/*<slug>*/template.json,里面有精确的 palette / typography(hex + 字体名)。
  3. 8 个内置 visual-style(Swiss Pulse / Velvet Standard / Shadow Cut / Maximalist 等)。在 hyperframes skill 的 visual-styles.md 里,直接抄 YAML token。

字体一律本地 woff2(见 Gotcha "字体")。中文必须配 Noto Sans SC(400/500/700/900 视用量);英文 display 按 frame 选(Archivo Black / Manrope / Oswald…);标签数字常用 JetBrains Mono。从 fontsource CDN 下到项目的 fonts/

curl -sSL -o fonts/<name>.woff2 "https://cdn.jsdelivr.net/fontsource/fonts/<family>@latest/<subset>-<weight>-normal.woff2"
# 中文:subset 用 chinese-simplified;拉丁:latin

Step 2 · 起项目

cd <repo>/studio/videos                       # 仓库约定:成片放这里
npx hyperframes init <YYYYMMDD-slug> --example blank --non-interactive
cd <YYYYMMDD-slug> && mkdir -p fonts audio
cp <user-audio> audio/narration-full.mp3
cp <user-srt>   audio/narration.srt
