InfiniteTalk is an AI-powered video tool that transforms images or existing videos into realistic talking videos using user-provided audio. By synchronizing lip movements, facial expressions, and head gestures with the speech, the platform produces natural-looking AI videos without traditional editing. Users can upload a photo or video and an audio track to generate expressive content suitable for presentations, storytelling, tutorials, marketing, and social media. InfiniteTalk simplifies dynamic video creation directly in a browser, making speech-driven video production accessible to all.
