“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Pacing Rules

Content TypeWords Per MinuteNotes
Standard narration150 wpmConversational pace
Complex/technical120 wpmAllow processing time
Energetic/social170 wpmFaster for short-form
Children's content100 wpmClear and slow

Key rule: 1 scene per key message. Don't pack multiple ideas into one visual.

Scene Duration Guidelines

  • Establishing shot: 3-5 seconds
  • Feature demonstration: 5-8 seconds
  • Text/stat on screen: 3-4 seconds (must be readable)
  • Transition: 0.5-1 second
  • CTA screen: 3-5 seconds

Voiceover Script Writing Tips

  • Short sentences. Max 15 words per sentence.
  • Active voice. "You can track your data" not "Your data can be tracked."
  • Conversational tone. Read it aloud — if it sounds stiff, rewrite.
  • One idea per sentence. One sentence per visual beat.

Pacing Control in TTS

TechniqueEffectExample
Period .Medium pause"This changes everything. Here's how."
Ellipsis ...Long pause (dramatic)"And the result... was incredible."
Comma ,Short pause"Fast, simple, powerful."
Exclamation !Emphasis/energy"Start building today!"
Question ?Rising intonation"What if there was a better way?"

Music & Audio

Background Music Guidelines

  • Volume: 20-30% under narration (duck 6-12dB when voice plays)
  • Style: match the brand tone (corporate = ambient electronic, startup = upbeat indie)
  • Structure: intro swell (first 3s) -> subtle loop under narration -> swell at CTA
  • No vocals: instrumental only under narration

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
