Multi-Language Dubbing and Lip Sync: A Practical Localization Workflow

Localization is not just translation. The goal is to keep the same persuasion—the same hook, clarity, and trust cues—in another language.

When to use dubbing vs subtitles

• Dubbing: best for talking-head, tutorial, and direct-response ads.
• Subtitles: best for fast iteration and social-first consumption.
• Both: often best for performance (voice + readable reinforcement).

A 6-step localization workflow

1. Pick markets: start with 1–2 languages based on demand and logistics.
2. Lock the claim: decide what must stay identical vs adapt.
3. Adapt the script: translate meaning, not word-by-word phrasing.
4. Dubbing + lip sync: match cadence and pauses when possible.
5. Subtitles: keep lines short, mobile-first, and readable.
6. QA: check timing, compliance, and cultural references.

QA checklist for localized videos

• Numbers, prices, currency, and units are correct.
• Disclaimers match market and platform policy.
• Audio levels are consistent (no sudden loudness changes).
• Subtitles don’t cover critical UI/product details.
• Hook still makes sense in the first 2–3 seconds.

Common mistakes that hurt conversions

• Literal translation that feels unnatural.
• Idioms/slang that don’t exist in the target market.
• Ignoring local buying context (shipping, returns, payment methods).
