This article is a practical guide to writing scripts (AI voiceover) and subtitles for personalized videos in Studio.

What “good” looks like

Keep videos at 20–30 seconds when the goal is conversion.

Start personalization early, usually with first_name.

Keep the voiceover simple, and use visuals for details.

Use one clear CTA.

Always include subtitles since many viewers watch muted.

Plan the script around personalization

Personalization is powerful, but it must feel natural.

Recommended “sweet spot”

Aim for 1–3 personalizations, and use only personal data that is clearly relevant. Avoid sensitive data like full addresses.

Common, high-performing personalizations

Use first_name in the AI voice and on-screen text.

Use place_name or another online location field if it supports the CTA.

Use contextual fields only when they truly help the viewer, such as car model, booking date, or appointment time.

Use a simple structure

A reliable structure for short personalized videos is Hook → Context → Proposition → CTA.

Hook (personalized)

Say and show the name early.

Example: “Hi, first_name!”
