InfiniteTalk

InfiniteTalk AI is an audio-driven AI video generator that turns a photo or video into a realistic talking video. Simply upload an image (or video) and your audio, and the system automatically creates natural lip-sync, facial expressions, head movement, and subtle body motion that match the speech.
Unlike basic lip-sync tools, InfiniteTalk uses advanced motion modeling to keep videos stable and expressive, even for long-form content. It supports unlimited video length, multiple resolutions (up to 1080p), and optional text prompts to control emotion or style. The platform also offers a multi-character mode for conversations or duets.
