LongCat Avatar – Audio-Driven Realistic Talking Videos
About
LongCat Avatar transforms static images into expressive, talking videos using advanced audio-driven technology.

Perfect for creating virtual assistants, educational content, and digital storytelling without visual degradation.
Key Features
Perfect Lip‑Syncing
High-precision audio-driven lip and mouth movement alignment to ensure realistic speaking motion that matches input audio or text-to-speech.
Long‑Form Stability (up to 2 minutes)
Maintains consistent identity and avoids temporal drift across long clips, enabling stable, publish-ready videos for extended content.
Multi‑Input Generation
Supports photo + audio, text + audio, and combined multi-track audio inputs to produce flexible avatar videos from different media sources.
Natural Full‑Body and Facial Motion
Generates smooth head, eye, shoulder, and facial dynamics (not just lips) for more expressive and engaging avatar performances.
HD Output & Fast Rendering
Export options up to 720p and an optimized generation pipeline for quick turnaround; credit-based pricing for scalable usage.
