Definition
Lip sync in video production is the synchronization of a character's or person's lip movements with an audio track, either naturally filmed or generated by AI.
Lip Sync explained
Accurate lip sync is essential for voiceover-driven content, dubbing, and AI avatar videos. AI lip sync technology analyzes the phonemes in an audio track and maps them to corresponding mouth shapes on a video subject. This enables creators to make existing footage 'speak' new dialogue, create multilingual versions of content, or generate AI avatar presenters with synchronized speech. The technology has advanced rapidly, with models producing near-photorealistic results. In faceless video workflows, lip sync is less relevant since the creator is not on camera, but it is important for talking-head and educational content formats.
