Why creators choose Sync Lipsync 3

Sync Lipsync 3 moves past frame-by-frame processing to understand a face holistically. That changes what you can sync in a single pass. Extreme angles land first time, close-ups stay sharp, and hands waving in front of the mouth don't break the sync. The model represents a generational leap for creators who work with challenging footage, tight schedules, or footage that earlier models couldn't handle reliably.

Global face understanding

Earlier lip sync models processed video frame by frame, treating each frame independently. Sync Lipsync 3 builds a complete map of a speaker's face across the entire shot in one generation. That global understanding means it catches the subtle angle of the jaw at a side profile, the way light plays across cheek movement, and consistency across cuts.

Close-ups and extreme angles

Close-ups are where lip sync usually breaks. Small movements matter, and errors are hard to miss. Sync Lipsync 3 handles them. So do extreme angles, including over-the-shoulder shots, side profiles, and even footage where the speaker turns their head mid-sentence.

Obstruction handling

A hand in front of the mouth, a microphone, a scarf pulled up (these are edge cases that trip up older models). Sync Lipsync 3 works around them. If the mouth is partially hidden, it infers the movement from the visible speech patterns and surrounding facial motion.

One pass, any resolution

Sync Lipsync 3 generates the entire sync in a single pass, without needing intermediate steps or separate processing for special cases. It works at any resolution and aspect ratio.

How to use Sync Lipsync 3 in Craze

Sync Lipsync 3 is a transform model: you bring the video and the audio, and Craze handles the rest.

1. Upload your video and the audio you want to sync to it. This could be a voiceover, a dubbed performance, or a completely new audio track.
2. In the Models panel or chat, ask for Sync Lipsync 3, or say you want to sync the lip movements to the audio. If you don't name a model, Craze shows the available lip sync options with their prices.
3. Craze processes the video against the audio and delivers the result with matching lip movements.
4. Review it in the editor. If the sync misses a beat, regenerate just that section or the whole video.

Sync Lipsync 3 works best on clear close-ups and shots where the mouth is visible and well-lit. Complex crowd scenes or footage where people are far from the camera may need Craze's agent to break them down into usable shots first.

Who Sync Lipsync 3 is for

Video dubbing and localization

Sync Lipsync 3 makes dubbing fast. Record a voiceover in any language, sync it to the original video in seconds, and the lip movements match. No need for expensive ADR studios or manual dialogue replacement.

Dialogue replacement and reshoots

A line needs to change. An actor flubbed a take. Sync Lipsync 3 lets you record a new line and sync it to the existing footage without reshooting the whole scene.

Character animation and AI video

If you've generated characters with another AI model or built them by hand, Sync Lipsync 3 can sync their speech to audio. The model works on 3D renders, live action, and AI video alike.

Accessibility and content adaptation

Creators making content for multiple regions can record one performance and sync it to dubbed audio for each language. The lip movements stay credible, and viewers get authentic performances in their language.

Interview and documentary editing

Documentary filmmakers often cut and rearrange interviews to find the best narrative flow. Sync Lipsync 3 lets you edit audio first, then sync the lip movements to match. A quote that works better out of sequence can be reordered without breaking the visual sync.

Voiceover for existing footage

Content creators who work with stock footage or archived material can add voiceovers that look like the original speaker. Whether you're adding narration to silent footage or replacing an awkward line, Sync Lipsync 3 makes the sync look natural even on challenging angles.
