FAQ from LipSync.video

What is LipSync.video?

LipSync.video is a frictionless, web-native AI tool that generates photorealistic lip movements synced to speech — all without downloads, subscriptions, or sign-up. Designed for creators, educators, marketers, and hobbyists, it transforms videos, photos, and cartoons into expressive, audio-aligned content in under a minute.

How to use LipSync.video?

No tutorials required. Upload a video showing a clear face, add audio (or paste text), click Generate — and download your lip-synced result. That’s it. No timeline scrubbing, no manual keyframing, no software to install.

What is AI Lip Sync?

AI Lip Sync uses neural networks trained on thousands of hours of speech-video pairs to predict how lips, jaw, and tongue move for each sound (phoneme). Unlike basic mouth-cycling tools, LipSync.video produces context-aware, fluid articulation — matching rhythm, stress, and even subtle emotional cues.

What video formats are supported?

We accept MP4, MOV, AVI, and WebM (H.264 encoded). For best results, use 720p or higher, well-lit, stable shots with consistent face framing. Audio files: MP3, WAV, M4A, or direct text input.

Do I need prior experience?

None. LipSync.video was built for beginners — if you can upload a file and click a button, you’re ready to create professional lip-synced videos.

How accurate is the lip syncing?

Our model achieves >94% phoneme alignment accuracy across diverse accents and speaking styles — validated against industry benchmarks. Mouth shapes respond naturally to plosives (/p/, /b/), fricatives (/s/, /f/), and vowel transitions — delivering broadcast-ready realism.

How long does processing take?

Typical turnaround: 45–120 seconds for 15-second clips. Longer or high-resolution videos may take up to 5 minutes. You’ll receive an instant download link upon completion — no waiting in queues.

Can I download my video in full quality?

Yes — every export is 1080p MP4 (H.264), DRM-free, and fully licensed for personal and commercial use. No watermarks, no compression artifacts, no hidden limits.

Is my data private and secure?

Absolutely. All uploads are encrypted in transit and automatically deleted from our servers within 2 hours of generation. We never store, train on, or share your media — privacy is foundational to our design.
