Pacing Rules

Standard narration	150 wpm	Conversational pace
Complex/technical

120 wpm | Allow processing time | | Energetic/social | 170 wpm | Faster for short-form | | Children's content | 100 wpm | Clear 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 Production

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.

Generating Voiceover

CODEBLOCK3

Pacing Control in TTS

Technique	Effect	Example
Period INLINECODE1	Medium pause	"This changes everything. Here's how."
Ellipsis INLINECODE2

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
