InfiniteTalk Fast Audio-Driven Avatar Lipsync Image-To-Video Conversational AI

infinitetalk-fast

What is infinitetalk-fast?

infinitetalk-fast 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.

How to Use

1. Upload the audio file.
2. Upload the image (the person to animate).
3. (Optional) Upload a mask_image to specify which regions can move.
4. (Optional) Add a prompt to guide expression, style, or pose.
5. Set the seed (set a fixed number for reproducibility).
6. Submit the job and download the result once it's ready.

Pricing

Note

• Max clip length per job: up to 10 minutes
• Processing speed: approximately 10–30 seconds of wall time per 1 second of video (varies by resolution and queue load)
• Mask safety tip: Do not upload the full image as mask_image. The mask should only cover the regions you want to animate—otherwise the result may render as fully black.
