LipsyncX

LipsyncX runs on the web and is built for long-form talking videos, such as podcasts, audiobooks and YouTube episodes.

It is an AI lip sync generator that turns a static photo or an existing video into a talking-head clip, with mouth movements matched to an audio file or a text script.

Dubbing is the other main use.

LipsyncX supports more than 50 languages, so you can translate a video and have the lips follow the new audio instead of leaving a mismatch on screen.

Batch processing is included, which matters if you are working through a back catalog or producing episodes on a regular schedule.

The focus on length is the useful part.

Many lip sync tools are geared toward short clips, while LipsyncX targets creators and teams who want to avoid the cost of filming every video again.

Pricing is not covered here, so check the site for plans.
