How natural does the lip sync look?

AdCreate's lip sync produces highly natural results that are difficult to distinguish from authentic footage. The AI generates accurate phoneme-level mouth shapes, natural jaw movements, and appropriate facial expressions. Results are significantly better than traditional dubbing and comparable to professional VFX lip sync work.

What languages are supported for lip sync?

Lip sync supports 40+ languages including English, Spanish, French, German, Portuguese, Italian, Japanese, Korean, Mandarin Chinese, Arabic, Hindi, Turkish, Dutch, Polish, and many more. The AI understands the phoneme systems of each language and generates appropriate mouth shapes.

Can I use lip sync with AI-generated avatars?

Yes. Lip sync works seamlessly with AdCreate's AI talking avatars. Generate an avatar video in one language, then create lip-synced versions in other languages. This is the most efficient way to produce multilingual spokesperson content without any filming.

Does lip sync work with group shots or multiple speakers?

Lip sync works best with single-speaker footage where the face is clearly visible. For multi-speaker content, you can process each speaker's segments separately. Group shots with multiple simultaneous speakers are not currently supported.

What video quality is preserved?

The output maintains the original video resolution and quality. The AI only modifies the mouth and lower face region, preserving all other elements of the frame — background, clothing, hair, and upper facial expressions remain untouched.

Everything You Need to Know About Lip Sync

AdCreate's AI Lip Sync technology takes any video of a speaking person and re-synchronizes their mouth movements to match new audio — in any of 40+ supported languages. The AI analyzes the target audio (whether it is a translated voiceover, a different speaker's voice, or text-to-speech output), then generates natural-looking lip movements that match the new audio precisely. The result is a video where the person appears to be naturally speaking the new language or delivering the new script, with realistic jaw motion, lip shapes, and facial expressions that maintain the authenticity of the original footage.

This capability is transformative for multilingual content strategies. A single talking-head video can be repurposed across every market by generating translated voiceovers and applying AI lip sync — producing results that look like the speaker actually recorded in each language. For brands with executives, spokespeople, or influencers who appear in video content, lip sync eliminates the need for those individuals to re-record in multiple languages (or the uncanny effect of traditional dubbing where the audio clearly does not match the mouth movements).

The technology works with AdCreate's AI avatar system as well as real footage. Generate a talking avatar video, then lip-sync it to different languages for global distribution. Upload a real spokesperson video and create lip-synced versions in Spanish, Mandarin, Arabic, Hindi, and dozens more. Combine with AdCreate's text-to-speech engine to generate the voiceover and lip sync in a single workflow — type a script, select a voice, choose the language, and the platform handles everything from voice generation to lip synchronization automatically.
