Introduction of InfiniteTalk

You can use InfiniteTalk to transform a single portrait image and an audio clip into a natural, lip-synced talking video. Powered by the MultiTalk model and the WanVideo 2.1 I2V GGUF backbone, it delivers expressive facial motion while maintaining identity and style, ideal for creating social clips, dubs, or avatar updates.

InfiniteTalk lets you turn still photos into expressive, speech-driven portrait videos. It is designed for creators, content strategists, and developers who want fluid talking avatars with accurate mouth motion synced to audio. The results are clips that preserve character likeness while adding natural gesture and vocal synchronization.

Key Models for InfiniteTalk

Wan2.1-MultiTalk (GGUF, InfiniteTalk variant)

The MultiTalk InfiniteTalk variant drives phoneme-aware lip and jaw motion from speech audio to ensure highly synchronized talking-head animation. It tracks natural speech timing and supports expressive delivery while maintaining face stability. Learn more about its origins in MeiGen-AI/MultiTalk.

WanVideo 2.1 I2V 14B (GGUF)

WanVideo 2.1 I2V 14B is the core image-to-video generator that animates portraits while preserving likeness, pose, and lighting. It is optimized in GGUF format for compatibility and quality. Recommended weights are available in city96/Wan2.1-I2V-14B-480P-gguf.

Wav2Vec2 (Tencent GameMate)

This audio model extracts robust speech representations from raw voice recordings. It enhances natural synchronization and prosody when passed to MultiTalk for animation guidance. It is publicly available at TencentGameMate/chinese-wav2vec2-base.

How to Use InfiniteTalk

Inputs Required

You need to provide three key inputs: an Image using the Image input, an Audio file through Audio, and a Prompt with the text prompt control. These allow InfiniteTalk to lock image identity, capture speech dynamics, and apply stylistic cues for the resulting talking video.

Optional Inputs and Controls

You can adjust Width and Height inputs to set video dimensions according to your preference, ensuring balance between performance and detail. Parameters like Seed, Steps, and Shift allow additional control over how the animation is generated, while Frames Per Second (FPS) ensures smooth playback.

Outputs

InfiniteTalk generates videos that combine your portrait and audio. The Video output is governed by Frames Per Second, producing a consistent experience such as 25 fps by default. The result is a fluid talking portrait clip that matches voice and image identity.

Best Practices

For best results, use a sharp portrait with even lighting in the Image input and clean speech audio in Audio. Keep the Prompt concise to describe tone or motion style. Start with standard Width and Height values and modest Steps for fast previews, then refine parameters for higher quality once satisfied.
