AI Video Translation with Lip Sync

Translate videos into new languages with perfectly synchronized lip movements, so your content feels native in every market.

In short: Video translation with lip sync goes beyond subtitles and voiceovers. It creates a version of your video where the speaker appears to natively speak the target language, with mouth movements that match the translated audio.

Video translation with lip sync goes beyond subtitles and voiceovers. It creates a version of your video where the speaker appears to natively speak the target language, with mouth movements that match the translated audio. This is a high-value capability for creators and businesses expanding into international markets, where viewers engage significantly more with content that looks and sounds local.

The workflow pairs AI translation or professional voice dubbing with AI lip sync from tools like Sync. The result is a translated video that feels authentic rather than overlaid, which is why video translation with lip sync has become the standard for platforms, agencies, and global brands.

How It Works

Start with your original video and a translated audio track in the target language. Upload both to Sync, and the AI re-maps the speaker's mouth movements to match the new audio. You receive a translated video where the speaker appears to naturally speak the target language.

Benefits

✓ Reach international audiences with video that feels native, not dubbed.
✓ Increase watch time and engagement compared to subtitles or traditional voiceovers.
✓ Scale one video into multiple language versions without reshooting.

Frequently Asked Questions

How is video translation with lip sync different from subtitles? +

Subtitles overlay text while the original audio and lip movements remain unchanged. Video translation with lip sync replaces the audio and adjusts the speaker's mouth to match, so the viewer experiences the content as if it were originally produced in their language.

Can I use AI-generated voice translations or do I need human voice actors? +

Both work. Many creators pair AI voice translation tools like ElevenLabs with Sync for a fully automated pipeline. For premium content, professional voice actors provide the translated audio and Sync handles the lip sync.

What kind of content benefits most from video translation with lip sync? +

YouTube videos, online courses, product demos, corporate communications, and marketing videos see the biggest impact because viewers expect to see the speaker's lips match what they hear.
