This feature is available on all plans.
For Freemium/Starter/Creator plan users: Dubbing minutes are deducted from your total video minute balance. You will be unable to publish videos dubbed from a YouTube link. Self-serve users will not have access to Dubbing with lip-sync.
For Enterprise users: This is a paid add on. Enterprise users can purchase minute packs. Prices vary by volume.
If you would like discuss upgrading your plan, please contact our Synthesia Support team or use our upgrade guide.
To use AI Video Dubbing:
Locate Video dubbing in the sidebar.
Click or drag to upload the video you want to dub into another language. You can also paste a YouTube video link.
Set the following parameters:
Project name
Original language
Number of speakers
Dub to (Select the language(s) for dubbing)
Click Generate.
A folder will be created in the My videos section, including the original and dubbed version(s) of the video. The dubbed video will retain the original voices, match lip movements to the translated voice (Enterprise only), and preserve the speaker’s tone and delivery style.
Once generated, publish the desired videos. If multiple language versions are published, they will all be accessible via a single link using the multilingual video player.
