InfiniteTalk

lip-synced talking videos using audio with an image or video input. Built on cutting-edge sparse-frame video dubbing technology, the platform synchronizes not only lip movements but also head motion, facial expressions, and body posture to match the provided speech, delivering lifelike, expressive talking avatars. InfiniteTalk supports both image-to-video and video-to-video workflows. Users upload a photo or existing video and corresponding audio, and the AI generates a new video where the subject speaks naturally and fluidly in sync with the audio. A key feature of InfiniteTalk is its ability to produce unlimited-length talking videos while preserving identity consistency and smooth motion over extended durations, making it suitable for tutorials, presentations, storytelling, marketing content, or educational material The platform offers flexible resolution options (e.g., 480p, 720p) and intuitive generation steps, allowing both beginners and professionals to create high-quality talking video content quickly and efficiently.
