short-video-production

short-video-production is a skill for Claude Code, Codex from chadixearth/graphyloop. It costs 49 tokens per session (527 once invoked), scanned A, original, MIT.

A workflow for turning a finished script into a rendered one-minute vertical video with timed scenes, captions, and voiceover alignment.

In plain words
What is it for?
It helps create 9:16 MP4 videos for Shorts, TikTok, and Reels from an existing script, including scene composition and word-synced captions.
Why use it?
It removes the need to manually coordinate scene timing, mobile captions, animation, and video rendering. It is for production, not writing the story.

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

short-video-production scanned grade A with 0 findings 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 6d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Short Video Production

1. Overview

Pipeline from script to rendered MP4: script with per-scene timing → composition (HTML/CSS-keyframe, deterministic) → render → 9:16 MP4.

Default renderer: HyperFrames (HTML→video, local, deterministic). Read the hyperframes skill first — hyperframes-core for composition contract, hyperframes-cli for commands — before building.

2. 60s Scene Plan

5-6 scenes matching story-engineering beat sheet:

Time Scene
0-3s Hook
3-8s Context
8-45s Body (2-3 scenes, micro-payoffs)
45-55s Payoff
55-60s CTA

3. Composition Rules

  • 9:16 (1080x1920) for Shorts/TikTok/Reels
  • One visual idea per scene
  • Captions word-synced to voiceover (show the spoken word chunk)
  • Text large and mobile-readable
  • No flicker / animation overload — deterministic keyframes only
  • Prefer transform/opacity animation (60fps safe)

4. Voiceover

  • ~150-160 words per 60s; 2.5-2.7 words/sec
  • Mark per-scene word counts in the script
  • Pause 0.3-0.5s at beat boundaries
  • No TTS key available → render silent with captions, note audio step

5. Render Checklist

  • Verify composition validates (hyperframes lint / validate)
  • Render at 1080x1920
  • Check hook frame: first 3s must show tension text
  • Check captions legible on small screen
  • Export MP4
  • Name output video.mp4

6. Common Failures

  • Bare waitForLoadState hangs on SSE pages — never use
  • Browser timeouts must be explicit (page.goto 15000ms)
  • Render fails twice → stop and report, no silent looping

7. Cross-Reference

  • story-engineering — source story
  • video-ai-automation — tool stack incl. TTS options
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
