Frequently asked questions
Answers to common questions about AI lip sync, exports, and best practices.
Lip sync 1 is an AI lip sync generator that analyzes your audio and predicts mouth shapes over time. Machine learning aligns phonemes to frames, producing natural-looking speech animation on your face footage.
You can use a face video for the most natural motion, but a single image can work for simpler talking-head results. Clear, front-facing faces with good lighting improve AI lip sync quality.
Use clean speech with minimal background noise and steady volume. Higher-quality recordings help the AI detect phonemes correctly, improving timing, articulation, and overall mouth movement realism.
Trim the clip tightly to the spoken segment, then adjust the start offset and rerun sync. Shorter segments often sync better, and re-exporting after small tweaks usually resolves drift.
Export options typically include common video formats and multiple resolutions for editing or publishing. Choose higher resolution for final delivery and lighter settings for quick reviews and iterations.
