Synthesia
Localize training and HR videos with AI avatars and dubbing, with consent done properly.
Start: What Synthesia is and where things liveAbout Synthesia
Synthesia makes AI avatar videos for training, HR, sales and customer education. You build a video scene by scene, with a script for each scene and a stock or custom avatar to present it. You can dub or translate videos into other languages and share them as a link, an embed or a SCORM package. Custom avatars need recorded consent from the person shown, and every video goes through moderation when you generate it.
Best for: Trainers, HR teams and marketers who need clear videos in several languages without a film crew.
Good for
- Turning a written script into a presenter-led video
- Dubbing a video into another language, with optional lip sync
- Keeping videos on brand with templates and brand kits
- Adding buttons, branching and quizzes to training videos
Where people slip
- Making an avatar of someone without their recorded consent
- Expecting dubbing to translate on-screen text. It translates spoken audio only
- Generating before you preview. Previews are free, but generating uses minutes or credits
- Forgetting to Reshare, so viewers still see the old published version
Can I make an avatar of myself in Synthesia?
Yes, on Starter and above. Record or upload one continuous take of 1 to 5 minutes, then record a consent video with the on-screen script. The person in both videos must be the same. Processing takes about one business day.
Is there a free Synthesia plan?
Yes. The Basic plan is free for exploring the editor and testing avatars and voices. Its videos carry a Synthesia watermark, and personal avatars aren't included. Starter, Pro and Enterprise add more.
What's the difference between dubbing and translating in Synthesia?
Dubbing works on a video you upload and translates the spoken audio only. Translate, on Enterprise, works on videos built in Synthesia and makes new language versions, with an option to translate only the script. Use the Glossary to keep brand terms untranslated.
Why was my Synthesia video rejected?
Every video is moderated, first automatically and sometimes by a person. A rejection gives a general reason. Duplicate the video, edit it to fit the notice and policies, then resubmit. You can also appeal. Resubmitting the same video many times can slow review.
