InfiniteTalk AI is an advanced audio‑driven video generation platform that creates realistic talking videos by syncing audio with visuals using cutting‑edge sparse‑frame dubbing technology. It supports both image‑to‑video and video‑to‑video workflows, allowing users to animate static portraits or dub existing clips with natural lip‑sync, full‑body motion, and expressive facial movement.

Key Features

Audio‑Driven Video Creation

Simply upload an image or video plus your audio (speech, podcast, or dialogue), and InfiniteTalk AI generates a lifelike talking video with precise lip sync, head movement, posture, and facial expressions that match the speech.

Sparse‑Frame Dubbing Technology

Unlike basic lip‑sync tools, InfiniteTalk synchronizes not only the mouth but also head tilts, posture shifts, and body motion for truly natural results.

Unlimited/Long‑Form Videos

Generate videos of any length — from short clips to extended lectures, tutorials, or stories — without typical duration limits.

Multi‑Character Support

With InfiniteTalk Multi, you can create videos of two or more characters speaking or singing naturally, each with separate audio tracks and synchronized motion.

Flexible Input & Output

Supports both image and video inputs and offers multiple export resolutions (such as 480p, 720p, and 1080p), making it ideal for social media, presentations, education, and professional content.

Prompt Control

Optional text prompts help guide facial expressions, gestures, or emotional tone for added personality in the generated videos.
