Lipsync videos

What are lipsync models on Replicate?

Lipsync models generate realistic mouth movements that match new audio tracks.
You can use them to make a still image or existing video appear as if it’s speaking naturally — perfect for dubbing, localization, animation, or creative storytelling.

How do lipsync models work?

These models analyze the phonemes and rhythm of the audio, then map those to the facial landmarks or motion of the person in your input image or video.
The result is a synchronized, natural-looking talking face that matches the speech timing and emotion of the audio.

What can I use lipsync models for?

Lipsync models are used across a range of applications:

• Dubbing and localization – make speakers appear to talk in a new language
• Virtual avatars and Vtubers – create expressive, talking digital personas
• Animated explainer videos or ads – sync narration to faces
• Film and creative production – quick dialogue retiming or AI character creation
• Accessibility tools – assist speech-impaired communication via synthesized talking heads

Which lipsync models are most popular?

Some of the most widely used models include:

• sync/lipsync-2 and sync/lipsync-2-pro – fast, high-quality studio-grade lipsyncs
• pixverse-ai/lipsync – smooth, expressive animation with realistic detail
• bytedance/omni-human – full digital human generation with synced lips, facial expressions, and motion
• kwaivgi/kling-lip-sync – lip synchronization with either audio or text inputs
• wan-ai/wan-2.2-s2v – convert audio clips and reference images into synced videos
• latentlabs/latentsync – high-quality, realistic lipsync for production use

What’s the difference between Lipsync 2 and Lipsync 2 Pro?

• sync/lipsync-2: Great for creators and developers who want fast and consistent lipsyncs with minimal setup.
• sync/lipsync-2-pro: Offers studio-grade quality with advanced emotional nuance, facial alignment, and high fidelity — ideal for professional video production and cinematic projects.

Which models are best for making videos from images?

If you’re starting from a single image, try:

• bytedance/omni-human or latentlabs/latentsync for realism
• cjwbw/sadtalker for stylized animation
• cjwbw/aniportrait-audio2vid for portrait-driven animation
• wan-ai/wan-2.2-s2v if you want to generate full talking head videos with both voice and motion

Can I use these models for dubbing and translation?

Yes — many users combine lipsync models with translation or speech generation models to create localized videos.
For example, you can:

1. Translate the script with a language model like openai/gpt-5 or anthropic/claude-4.5-sonnet.
2. Generate audio in the target language using minimax/speech-02-turbo or playht/text-to-speech.
3. Use sync/lipsync-2-pro or kwaivgi/kling-lip-sync to match the new voice to the video.

What are some creative use cases?

• Turn a photo into a speaking character
• Create AI news anchors or podcast clips
• Power interactive games or NPCs that respond in real time
• Produce personalized video messages or education content
• Generate music videos or dubbing memes synced to a beat

How do I pick the right lipsync model for my workflow?

It depends on your needs:

• For fast and reliable results → sync/lipsync-2
• For cinematic quality → sync/lipsync-2-pro
• For full-body digital humans → bytedance/omni-human
• For text-based or batch lip sync → kwaivgi/kling-lip-sync
• For photo-based stylized faces → cjwbw/sadtalker or cjwbw/aniportrait-audio2vid

Can I combine lipsync models with other AI models?

Absolutely.
You can chain lipsync models with:

• Text-to-speech (to generate dialogue)
• Image generation or restoration (to create or enhance faces)
• Video upscaling (to improve quality)
• Audio mixing tools (for synchronized soundscapes)

A common workflow is:
Prompt → TTS → Lipsync → Video Upscale for full end-to-end video production.

Are these models suitable for commercial use?

Yes — most official lipsync models on Replicate are licensed for commercial use.
Always check the individual model’s page to confirm usage rights, especially for outputs used in advertising, film, or paid content.

What’s the difference between “official” and community lipsync models?

• Official models (like sync/lipsync-2-pro, bytedance/omni-human, pixverse-ai/lipsync, kwaivgi/kling-lip-sync) are hosted and maintained for consistent quality and availability.
• Community models (like cjwbw/sadtalker or zsxkib/multitalk) are experimental and can vary in speed or realism, but are great for creative exploration.

Can I sync multiple people talking in one video?

Yes. The zsxkib/multitalk model supports multi-person conversational lipsync — you can upload multiple audio clips and generate a realistic back-and-forth conversation between characters.

How fast are lipsync models?

Speed depends on model complexity:

• sync/lipsync-2 and kwaivgi/kling-lip-sync: a few seconds per clip
• bytedance/omni-human and latentlabs/latentsync: slightly slower but higher quality
• Community models like cjwbw/sadtalker: may take longer but run on standard GPUs

Most official models are optimized for near real-time performance through Replicate’s infrastructure.

What are the best starting points for beginners?

Try these:

• sync/lipsync-2 → easy, fast, realistic
• bytedance/omni-human → premium, all-in-one digital human generation
• pixverse-ai/lipsync → simple interface, strong results
• cjwbw/sadtalker → fun stylized results for portraits

Once you’ve picked a model, you can upload an image, audio file, or text and instantly generate your first lipsynced video.
