InfiniteTalk

What is InfiniteTalk?

InfiniteTalk produces videos with precise lip sync, aligning the head, face, and body movements to the audio. It maintains identity across unlimited-length videos and also offers image-to-video generation, turning static photos into lively speaking or singing videos.

Why it looks great

• Accurate lip synchronization: aligns lip motion precisely with audio, preserving natural rhythm and pronunciation.

• Full-body coherence: captures head movements, facial expressions, and posture changes beyond the lips.

• Identity preservation: maintains consistent facial identity and visual style across frames.

• Image-to-video capability: turns static photos into realistic speaking or singing videos.

• Instruction following: accepts text prompts to control scene, pose, or behavior while syncing to audio.
