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.

Pricing

Billing Rules

• Minimum charge: 5 seconds

• Per-second rate = (price per 5 seconds) ÷ 5

• Billed duration = video length in seconds (rounded up), with a 5-second minimum

• Total cost = billed duration × per-second rate (by output resolution)

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. Select the resolution (480p or 720p).
6. Set the seed (set a fixed number for reproducibility).
7. Submit the job and download the result once it’s ready.

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)
