AI lip-sync for dubs, music videos, viral edits. Face smoothing, expression modes, 4K output. Beats HeyGen's $39/mo and D-ID's $45/mo.
You want to dub your video into Spanish. Or sync a song cover to your face. Or make a viral edit. The AI lip-sync tools all charge subscription, even for one-off use.

Real lip-sync alignment. Real face smoothing. Real 4K output.
Talking-head MP4 / MOV. Up to 2GB. Any aspect ratio.
Target voice MP3 / WAV / FLAC. Same length or shorter than video.
Natural · Enhanced (subtle exaggeration) · Dramatic (music video intensity) · Subtle (podcast).
Up to 4K output. Face smoothing slider. Timing offset for sync correction. Live progress.
Not a face-swap filter. Real lip-shape alignment to audio waveform.
Analyzes audio waveform → maps to mouth shapes → re-renders lip region. Frame-by-frame timing match.
Natural · Enhanced · Dramatic · Subtle. Each tunes mouth movement intensity + facial expression curve.
Bilateral filter on facial skin. Smooths compression artifacts WITHOUT plastic look. 0-100 slider.
-500ms to +500ms manual offset. Fix audio-video drift from source files. 1ms precision.
Output resolutions: 720p / 1080p / 4K. Bitrate auto-selected per resolution (CRF 16-26).
Works with audio in any language. Lip-sync is language-agnostic (it maps phonemes, not words).
Standard (CRF 26, fast) · High (CRF 20, balanced) · Ultra (CRF 16, slow but pristine).
MP4 H.264 (universal) or WebM VP9 (smaller, modern). Both ready for upload anywhere.

3 free 720p syncs per day. Upgrade for 4K, batch processing, and longer videos.
Natural mode is the most realistic — slight mouth movement match. Dramatic mode is intentionally exaggerated for music-video / viral content. Always preview before committing.
Yes — lip-sync is language-agnostic. The AI maps audio phonemes to mouth shapes, no language model needed. Works for dubs in any language.
Standard quality: ~1× video duration. High: ~2×. Ultra: ~4×. A 60-second clip in Ultra takes ~4 minutes server-side.
Best for talking-head content (front or 3/4 angle). Profile shots, multi-face shots, and obscured faces produce weaker results.
We use FFmpeg-based facial pipeline which is demographic-neutral (works on skin tone, lighting, age range). No "ethnic optimization" — same model for everyone.
Voice cloning is on the Studio tier roadmap (Q3). Today, bring your own audio (recorded, TTS, or AI-generated separately).
