Expanded FAQ
What is LIP-SYNC?
LIP-SYNC is an intelligent photo-to-video AI platform that converts static portraits into expressive, audio-driven talking videos—combining breakthrough audio perception, facial dynamics modeling, and temporal stability for unprecedented realism.
How do I use LIP-SYNC?
Upload a portrait → add audio (or type text for TTS) → click Generate → download or share your synced video. History saves all outputs automatically—refresh to view.
How does LIP-SYNC differ from traditional lip syncing?
Traditional methods map phonemes to rigid mouth shapes. LIP-SYNC models speech as a full-body communicative act—interpreting pitch contour, syllable stress, silence duration, and speaker intent to animate lips, eyes, and head in concert.
Can I use LIP-SYNC videos commercially?
Yes. All paid plans include full commercial usage rights—including monetization, redistribution, and integration into client-facing products—without attribution or royalties.
What file formats does LIP-SYNC accept?
Images: PNG, JPG, JPEG, WEBP (recommended: 1024×1024+, front-facing, neutral expression, good lighting).
Audio: MP3, WAV, OGG, M4A (mono/stereo, ≤120 sec for free tier; longer with Pro).
How fast is video generation?
Most 30-second clips render in 45–90 seconds. Pro users benefit from priority GPU queues and accelerated batch processing—cutting wait times by up to 60%.
How can I maximize realism and sync accuracy?
✅ Use high-resolution, front-facing portraits with visible lips and teeth.
✅ Record or upload clean, uncompressed audio (avoid background noise or heavy compression).
✅ For TTS, select “Expressive” voice mode and add punctuation for natural pausing.
Is there a free version?
Yes—our Free Plan includes 3 generations/month (720p, watermark-free), basic TTS, and full access to all core AI features. No trial expiration or hidden paywalls.
