What you can create
Use existing footage
Supply a video containing the speaker you want to synchronize. This model uses video input rather than a still portrait.
Choose the recording
Add the audio that should drive the mouth movement. Listen to the recording first and check that the speech is clear.
Review different input lengths
The Sync Mode setting controls how the model handles unequal audio and video lengths. Choose deliberately and inspect the ending.
From your idea to finished content
Open Sync 3 and add your video
Use the button to select Sync 3 in the lip-sync tool. Upload the footage you want to synchronize.
Add audio and review the settings
Upload the target recording and compare its length with the video. Review Sync Mode and the displayed credit cost.
Generate and inspect the result
Generate the video and watch the speaker closely. Check mouth movement, facial detail, and timing at the beginning and ending.
Two input preparation checklists
Sync 3 uses supplied video and audio. These checklists help you prepare those inputs.
Replace a short spoken introduction
Choose a clear shot of the speaker. Prepare the replacement recording. Compare file lengths and inspect the first and last words.
Use a revised line
Trim your source to the relevant passage. Upload the corrected recording. Review pauses and mouth movement throughout the resulting clip.

- Does Sync 3 write or record the replacement speech?
- This workflow uses supplied audio. Prepare the recording separately, then upload it alongside the video.
- What happens when the files have different lengths?
- Sync Mode controls length handling. The available modes include cut off, loop, bounce, silence, and remap. Review the selected result.
