Lip sync your webcam to a new voiceover, in any language
When your face is in the tutorial, a new voiceover can make it look dubbed. Braiv Lipsync matches the presenter's mouth to the optimized voiceover or to each translated language, as an option in Braiv Capture.
Where this fits
Braiv Capture
Braiv Capture is a native Mac app for tutorial videos. Talk through the task the way you normally would, and Capture rewrites the voiceover into clean sentences, re-voices it in your own voice with studio-mic sound, translates the audio and on-screen text, and lipsyncs your webcam. Then export to Braiv to package and publish.

What this does
What Braiv Lipsync fixes
Braiv Lipsync in Braiv Capture matches a webcam presenter's mouth movement to an optimized voiceover or a dubbed translation, so tutorial videos with a presenter bubble look natural in every language.
-
No dubbed-film look
Mouth movement matches the new words, so viewers stop noticing the voice was replaced.
-
Works after optimization
The rewritten, re-voiced script lines up with your face even where sentences changed.
-
Works in every language
Each translated version gets its own lipsync, so the presenter looks native in all of them.
-
Only when you need it
A toggle per project. Screen-only tutorials skip it and its credits.
Where it appears
One toggle, in the two places a new voice is made
Lipsync the speaker sits in both sheets that replace the voice in your recording.
Translate video
Lipsync every dubbed language
Each language you tick gets its own lipsynced presenter, alongside the translated text overlays.
Full video translationWhen to turn it on
Use it when a face is on screen
Lipsync works on the webcam track, so it only makes sense when you recorded one.
Presenter-led tutorials
Product walkthroughs, course lessons and onboarding videos where your webcam bubble is part of the frame.
Close-up or large bubbles
The bigger your face is in the frame, the more a mismatch shows, and the more lipsync helps.
Skip it for screen-only
No webcam, no lipsync needed. The voiceover and translations work exactly the same without it.
Deep dive
Everything you need to know about Braiv Lipsync for screen recordings
Why a new voiceover needs a matching face
Voiceover optimization and full video translation both replace what you said. For a screen-only tutorial, that is the whole job. With your webcam in the corner, it is not: the audio says one thing and your mouth says another, and viewers notice within a second.
Braiv Lipsync closes that gap. It matches the presenter’s mouth movement to the new voiceover, so the person in the bubble looks like they recorded this version.
How lip sync works in Braiv Capture
Lipsync is a toggle, Lipsync the speaker, in the two places Capture creates a new voice:
- Optimize voiceover, for your cleaned-up, re-voiced script in the original language.
- Translate video, for each language you dub into.
Turn it on, confirm the cost and Capture returns the voiceover with a lipsynced camera track. Everything else in the project, from text overlays to zooms, stays as it was.
Lip sync dubbing for tutorials, not films
Most lip sync dubbing software is built for finished footage: a film, an ad, a talking-head video. Capture is built for tutorials, where the presenter is a bubble on top of a screen recording and the lipsync has to follow the voiceover you just optimized or translated. Both use Braiv’s lipsync engine. For finished videos made elsewhere, use lip sync in Braiv Dubbing.

Frequently asked questions
What is lip sync AI?
Software that changes the mouth movement in a video to match a different audio track. In Braiv Capture it makes a webcam presenter look like they are saying the new words after you optimize or translate the voiceover.
How do I lip sync audio to a video with AI?
In Braiv Capture, switch on Lipsync the speaker when you run Optimize voiceover or Translate video. Braiv generates the new voiceover and matches your mouth movement on the webcam track to it.
Do I need a webcam recording?
Yes. Lipsync works on the camera track recorded with your tutorial. Screen-only tutorials do not need it.
Does it work with translations?
Yes. Each language you tick in Translate video can be lipsynced, so the presenter matches Spanish, German or Japanese as naturally as the original.
Is lipsync required?
No. It is optional per project. Optimize voiceover and translation work the same without it.
How much does lipsync cost?
Lipsync adds AI Credits on top of the voiceover or translation, based on the length of the video. Capture shows the total before you confirm. See pricing.
Can I lip sync videos that were not made in Capture?
Yes, through Braiv Dubbing. Upload any finished video and see the lip sync options for dubbed video.
