Create unlimited-length talking videos from audio

InfiniteTalk AI is an audio‑driven video generation platform that converts a single image or an existing video plus audio into lifelike talking videos. It uses sparse‑frame video dubbing to deliver accurate lip synchronization, expressive head and body motion, and consistent visual identity over extended durations.
The platform is designed for creators working with long‑form audio—such as podcasts, lectures, training content, and narration—as well as teams that need efficient dubbing and localization. It supports single‑person and multi‑person scenarios, enabling complex dialogue and multi‑character sequences with individual audio control.
Users start by selecting a source: either a single image or an existing video. They then upload the corresponding audio—speech, podcast, or dialogue—and can optionally provide transcripts. For multi‑person scenes, separate audio tracks and reference masks can be supplied to control each character’s alignment and timing.
The system applies sparse‑frame video dubbing to drive lip shapes, facial expressions, head movement, and body posture from the audio while maintaining the subject’s identity, lighting, and background. For video‑to‑video workflows, the platform preserves source framing and motion cues where appropriate. The result is a generated talking video that aligns closely with the audio track.
Exports are available in MP4 or WebM, as well as frame sequences for post‑production pipelines. Current resolution options include 480p and 720p, with higher resolutions planned. The pipeline supports long‑form and batch processing to handle extended content.
