InfiniteTalk Video-to-Video

What is InfiniteTalk?

InfiniteTalk creates new videos by combining an input silent video and an audio track. It ensures precise lip synchronization while aligning head, face, and body movements with the audio. With optional masking and prompting, you can control which areas move and how the scene appears. The model also maintains visual identity for natural and consistent results.

Why it looks great

• Accurate lip synchronization: matches lip motion precisely to the audio.
• Full-body coherence: aligns head pose, facial expressions, and posture with speech.
• Mask control: optional mask images let you define which regions can move.
• Instruction following: prompts can guide style, pose, or behavior.
• Identity preservation: ensures consistent visual identity across all frames.
