How to Translate Your Videos into Any Language
Translate any video into 140+ languages with natural voice matching and lip-sync.
Localizing your video into multiple languages allows you to connect on a deeper level with new global audiences.
However, video translation has always been super expensive, time-consuming, and often produced results with questionable quality (in particular when your video uses technical terms or regional accents and dialects).
AI has changed that, and AI video translation is now an accessible tool that any business or creator can leverage. You can now translate your video into multiple languages while preserving the original voices with perfect lip-sync.
Check out this example — try changing the language picker between English, French, German, and Spanish.
Pretty amazing, right?
In this guide I'll show you how you can do the same for your videos.

Tips for efficient video translation
Below are some tips to help you get the best results from AI video translation:
- Plan for translation: Make your life easier by trying to avoid idioms, cultural references, and complex metaphors when writing your video script from an early stage. Your video translation will be more accurate if you stick to simple and clear language.
- Be consistent with terminology: Try to use the same terms throughout your video so that the translated video will also be consistent. This is especially important for videos that use technical or branded terms.
- Provide visual context: Whenever possible, show your viewers what you're describing.
- Always review: You should always review AI-generated translations for accuracy and tone before publication to catch any misinterpretations. This is especially true for content with technical terminology.

Frequently asked questions
Should I translate my video with subtitles or dubbing?
Dubbing is the preferable option because it leads to a more immersive viewing experience and stronger viewer engagement.
However, subtitles are often the cheaper and simpler option. I like to use them when I'm testing out translating my video content into a new region or if I'm translating a new video content type. If I see traction, I'll then double down and get the video dubbed.
How much does AI dubbing cost?
Synthesia's AI Dubbing is available on the Starter plan which costs $19/month (paid monthly). This plan gives you access to 10 minutes of AI dubbing per month.
