How do I match a video's mouth to different audio? (Lip Sync)

Re-time a mouth to a new soundtrack — dub a clip, fix one line, or change the language.

Lip Sync re-times the mouth in existing footage to audio you supply. Dub a clip into another language, replace a fluffed line, or make a portrait read your script.

Making one

What makes it convincing

  • A clear, front-on, unobstructed face in the footage.
  • Clean audio. Background noise blurs the boundaries between sounds, and the mouth follows what it can hear.
  • Ordinary speaking pace. Very fast delivery, or a face turned well off-centre, both cost accuracy.

If it comes back off, try again from clearer footage. If it fails outright, start here.
