Transform Any Video into a Talking Masterpiece with InfiniteTalk Video-to-Video

The world of AI-generated video has taken another leap forward. WaveSpeedAI is excited to announce the availability of InfiniteTalk Video-to-Video, an audio-driven video generation model that transforms silent footage into realistic talking or singing videos with pixel-perfect lip synchronization.

Whether you’re creating content for marketing campaigns, educational tutorials, or entertainment projects, InfiniteTalk Video-to-Video offers a powerful solution for bringing your videos to life with natural, expressive movement that goes far beyond simple lip-sync.

What is InfiniteTalk Video-to-Video?

InfiniteTalk Video-to-Video is a sparse-frame video dubbing framework developed by MeiGen-AI and built upon the robust Wan2.1 video diffusion model. Given an input silent video and an audio track, the model synthesizes a new video with accurate lip synchronization while simultaneously aligning head movements, body posture, and facial expressions with the audio.

Unlike traditional dubbing tools that focus solely on mouth movements, InfiniteTalk captures the full spectrum of human expression. The result is video content where subjects appear naturally responsive to speech—moving their heads, shifting their gaze, and displaying micro-expressions that match the emotional tone of the audio.

The model leverages innovative sparse-frame processing technology and a context window mechanism (defaulting to 81 frames) that enables truly unlimited-length generation. This architectural approach preserves reference keyframes to maintain identity, iconic gestures, and camera trajectories while enabling holistic, audio-synchronized full-body motion editing.

Key Features

  • Pixel-Perfect Lip Synchronization: Advanced algorithms match lip motion precisely to audio, preserving natural rhythm and pronunciation patterns across any language
  • Full-Body Coherence: Goes beyond lips to synchronize head pose, facial expressions, gaze shifts, and posture changes with the speech
  • Unlimited Video Length: Generate videos up to 10 minutes long without the traditional limitations of short clip processing
  • Identity Preservation: Maintains consistent visual identity and facial characteristics across all frames, even in extended sequences
  • Mask Control: Optional mask images let you define exactly which regions can move, giving precise control over animation areas
  • Instruction Following: Text prompts can guide style, pose, or behavior while syncing to audio
  • Dual Resolution Support: Choose between 480p for faster processing or 720p for higher quality output
  • Reproducible Results: Seed control enables consistent, reproducible generations
