Generate realistic lipsync animations from audio using advanced algorithms for high-quality synchronization.
About this model
Sync Lipsync generates realistic lip-sync animations by matching audio to video. Upload an audio file (voiceover, dialogue, music with vocals) and a video file, and the model analyzes both to produce perfectly synchronized mouth movements. The output is a new video where the subject's lips naturally move in time with the audio—essential for avatar videos, dubbed content, or any scenario where video and audio originally mismatched.
This tool powers realistic avatar communication, multi-language dubbing, podcast-to-video workflows, and any creative project where synchronizing speech or singing to existing footage matters. Muapi's unified API and micro-pricing (under a cent per generation) makes lipsync generation accessible even in high-volume applications.

Frequently asked
Standard formats are supported: MP3, WAV, AAC for audio; MP4, WebM, MOV for video. The audio should be clear and intelligible, and the video should show the subject's face or mouth at reasonable clarity for the model to work effectively.
The model uses advanced phoneme analysis to match lip movements to audio timing and mouth shapes. Results are highly realistic for natural speech or singing, though very fast dialogue or unusual accents may occasionally require minor adjustments.
Sync Lipsync costs $0.04 per generation—less than a nickel per video. This micro-pricing makes it affordable even for high-volume lipsync projects like dubbed series or avatar-heavy platforms.
