The Problem

HeyGen is $39/mo. Synthesia is $30/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.

$30-45/mo subscriptions

HeyGen: $39/mo (1 hour). D-ID: $45/mo. Synthesia: $30/mo + per-minute. For occasional use, you're burning $300+/yr.

"Paid $39 to dub one video. Cancelled the next day."

Most tools = "AI avatar" only

HeyGen and Synthesia want you to use their stock avatars. Bring your own face? Pay extra. Custom voice? Pay extra.

"I just wanted to dub MY video into Spanish. Not create a fake person."

Free tools = 30-second cap

Free competitors limit you to 30 seconds, 720p, watermarked. Useless for actual production.

"Free tier was so limited it was bait."

What's Inside

Real sync. Real quality.

Not a face-swap filter. Real lip-shape alignment to audio waveform.

AI lip alignment

Analyzes audio waveform → maps to mouth shapes → re-renders lip region. Frame-by-frame timing match.

Waveform mapFrame-accurate

4 expression modes

Natural · Enhanced · Dramatic · Subtle. Each tunes mouth movement intensity + facial expression curve.

Face smoothing

Bilateral filter on facial skin. Smooths compression artifacts WITHOUT plastic look. 0-100 slider.

FAQ

Questions, answered.

Does the sync look natural or robotic?

Natural mode is the most realistic — slight mouth movement match. Dramatic mode is intentionally exaggerated for music-video / viral content. Always preview before committing.

Can I sync to a different language?

Yes — lip-sync is language-agnostic. The AI maps audio phonemes to mouth shapes, no language model needed. Works for dubs in any language.

How long does a sync take?

Standard quality: ~1× video duration. High: ~2×. Ultra: ~4×. A 60-second clip in Ultra takes ~4 minutes server-side.

Will it work with non-frontal faces?

Best for talking-head content (front or 3/4 angle). Profile shots, multi-face shots, and obscured faces produce weaker results.

Is the AI biased toward certain demographics?

We use FFmpeg-based facial pipeline which is demographic-neutral (works on skin tone, lighting, age range). No "ethnic optimization" — same model for everyone.

Can I clone my own voice for the audio?

Voice cloning is on the Studio tier roadmap (Q3). Today, bring your own audio (recorded, TTS, or AI-generated separately).
