InfiniteTalk

What is InfiniteTalk?

Given an input video and audio track, InfiniteTalk synthesizes a new video with accurate lip synchronization while simultaneously aligning head movements, body posture, and facial expressions with the audio. Unlike traditional dubbing methods that focus solely on lips, InfiniteTalk enables infinite-length video generation with accurate lip synchronization and consistent identity preservation. Beside, InfiniteTalk can also be used as an image-audio-to-video model with an image and an audio as input. InfiniteTalk transforms static photos into dynamic speaking videos by making the person speak or sing exactly what you want them to say.

Pricing

Our endpoint starts with $0.15 per 5 seconds video generation and supports a maximum generation length of 120 seconds.

How InfiniteTalk Works

InfiniteTalk leverages advanced AI technology to understand both audio signals and visual information.

Audio Analysis: InfiniteTalk uses a powerful audio encoder (Wav2Vec) to understand the nuances of speech, including rhythm, tone, and pronunciation patterns.

Visual Understanding: Built on the robust Wan2.1 video diffusion model (you can visit our Wan2.1 workflow for t2v/i2v eneration), InfiniteTalk understands human anatomy, facial expressions, and body movements.

Perfect Synchronization: Through sophisticated attention mechanisms, InfiniteTalk learns to perfectly align lip movements with audio while maintaining natural facial expressions and body language.

Instruction Following: Unlike simpler methods, InfiniteTalk can follow text prompts to control the scene, pose, and overall behavior while maintaining audio synchronization.
