01
Video and voice in one workflow
Upload the clip you want to animate and the audio track it should speak. Creatii keeps the inputs visible so the lip sync setup stays simple and easy to review.
How to make an AI lip sync video
Upload the source video
Choose a clear face-forward or speaking-style clip where the mouth area is visible enough for lip sync generation.
Add the voice audio
Upload the voice track, narration, translation, or short script recording you want the person or avatar to speak.
Generate and review sync
Create the lip-synced video, then review mouth timing, expression, and audio alignment before using the result.
Why Creatii Is Built for Natural AI Lip Sync Videos
Upload a video and a voice track, then generate a talking clip with mouth movement aligned to the audio. Creatii keeps the workflow focused on fast dubbing, avatar clips, explainers, and creator videos.
02
Mouth movement matched to audio
Create a new talking video where the visible speech motion follows the timing and rhythm of the uploaded voice track.
03
Made for creator and marketing clips
Use lip sync for avatar intros, product explainers, localized social clips, short ads, education snippets, and quick voiceover tests without reshooting footage.
04
Duration-aware generation
Creatii reads video and audio duration, estimates credits, and helps prevent mismatched uploads before the task starts.

Frequently Asked Questions
An AI lip sync generator updates mouth and facial speech movement in a video so it matches an audio track. It helps make a person or avatar appear to speak the uploaded voice.
You need a source video and an audio file. The video supplies the face and scene, while the audio supplies the speech timing for the final synced clip.
Yes. Lip sync is useful for dubbing tests, localized social clips, explainer videos, and voiceover variants when you want the visible speech to better match the new audio.
Use a clear video where the face is visible, lighting is stable, and the mouth is not heavily blocked. Extreme blur, profile-only angles, or heavy occlusion can make syncing harder.
No. Creatii keeps lip sync as an upload-and-generate workflow, so you do not need to manually animate mouth shapes or edit frame by frame.
Yes, as long as you have the rights and consent needed for the video, voice, and final use. Always review the result before publishing.
