InfiniteTalk AI

InfiniteTalk AI turns an image or existing video plus an audio track into a talking video, syncing lips, head movement, posture and expressions to the speech. It is built around the InfiniteTalk sparse-frame dubbing model and can produce long videos instead of short clips.

Besides the core InfiniteTalk mode, the site offers lip sync for existing footage, talking avatars, talking photos, a singer mode that makes a portrait sing, and music videos made from one photo and a song. It also gives access to Seedance 2.0 and 2.5 and Wan 2.2 speech-to-video for directed shots.

The model keeps the person's identity and the original camera motion when dubbing a video, which matters for translated or re-voiced content. Paid plans come with a monthly credit balance, and a ten-second 720p InfiniteTalk clip uses about 20 credits. Refunds are offered within 7 days.
