Key Features
Precise Lip Sync & Expression Alignment
Advanced audio-driven synchronization that aligns mouth shapes, facial expressions, head turns, and basic body posture to match speech rhythm and intonation for natural-looking talking videos.
Infinite-Length Generation
Generate lip-synced videos with no strict duration limit while preserving identity consistency and animation stability across long-form content like lectures, interviews, and podcasts.
Multi-Input Modes (Audio+Image / Audio+Video)
Create realistic talking portraits from a single image or dub existing footage by uploading a source video and a replacement voice track for seamless dubbing.
Prompt-Controlled Expressions & Motion
Use optional text prompts to guide expressions, gestures, and emotional tone, allowing fine-grained control over the avatar's performance without manual animation.
Resolution & Export Flexibility with High Stability
Export in multiple resolutions (480p/720p/1080p) and enjoy stable, distortion-free animations with reduced artifacts for professional or social outputs.
How to Use Infinite Talk AI
1) Choose Mode & Upload: Select Audio+Image to create a talking portrait or Audio+Video to dub existing footage. Upload a clear portrait image (PNG/JPG) or source video (MP4) and your audio file (MP3/WAV/M4A/OGG/FLAC). 2) Configure Settings: Pick the output resolution, adjust lip-sync or motion options, and optionally enter a text prompt to control expressions or gestures. 3) Generate: Click "Generate Video" to start the rendering process (uses credits). Wait for processing and preview the result. 4) Download & Iterate: Download the final video or tweak prompts/settings and re-run if needed. Tip: use clean audio and a clear, front-facing portrait for best results.
