Frequently Asked Questions (FAQs)
What is video localization?
Video localization adapts video content for different languages and regions. It includes translation, dubbing, subtitles, and visual alignment so content feels native rather than translated.
How is video localization different from simple translation?
Translation converts text or speech into another language. Localization adapts tone, delivery, timing, and accessibility to match how audiences naturally consume video in each region.
Do I need separate videos for each language?
No. HeyGen allows you to generate multiple localized versions from a single source video with the video translator. This keeps production centralized and consistent.
How accurate is AI video localization?
AI translation can vary by language, audio quality, and context. Use Review & Edit to check the translated script and Brand Glossary to keep product names and preferred terms consistent.
Can I localize videos with multiple speakers?
Yes. HeyGen supports multi-speaker detection and localization, making it easier to engage with a new audience. Each speaker is handled accurately for clarity and alignment.
Does localization improve video performance?
Localization can make video easier to understand by delivering spoken content and captions in the viewer's language. Engagement still depends on the content, market, channel, and distribution.
