Sync Lipsync 2 Pro
Frame-perfect lip sync from Sync Labs. Apply any speech audio to any video with the most accurate lip sync model available — precise at the frame level, indistinguishable in output.
What is Sync Lipsync 2 Pro?
Sync Lipsync 2 Pro is Sync Labs' professional lip sync model. It takes an existing video and a speech audio file as inputs and replaces the lip movement in the video to precisely match the speech — at the frame level.
"Frame-perfect" accuracy means the lip movement is synchronized to individual video frames rather than approximated at the word or phrase level. The result is lip sync that holds up under close inspection — the kind of accuracy required for professional delivery and broadcast contexts.
Applications include dubbing and localization (make a person appear to speak in a different language), content updating (replace an outdated script in existing video without reshooting), and any workflow where you need tight audio-visual alignment on a real or AI-generated person's face.

Best use cases
Localization and dubbing
Apply translated voiceover to a video of a person speaking in their original language. Sync Lipsync 2 Pro's frame-perfect accuracy makes dubbed content appear naturally lip-synced in the target language.
Script updates in existing footage
When a script change is needed in already-shot footage, re-record the updated voiceover and apply it with Sync Lipsync 2 Pro — the video remains unchanged except for the lip movement.
AI-generated spokesperson dubbing
Pair with avatar generation models: generate a spokesperson with OmniHuman or Creatify Aurora, then apply precise lip sync with Sync Lipsync 2 Pro for maximum accuracy in the final output.
Multilingual content at scale
Produce one master video, then apply locally-recorded voiceovers for each market. Frame-perfect sync ensures each language version looks as natural as the original.
