What do I need to get started?

A script or audio file, and either a photo (for an avatar) or an existing video (for dubbing). That's it. The agent handles the sync, the expressions, and the output. **Tips:** **Start with clean audio.** Slow, clear speech syncs better than anything rushed or mumbled. Read your script out loud first — if you stumble, rewrite it. **Write how people actually talk.** Use contractions. Keep sentences under 15 words. The model performs exactly what you give it, robotic script = robotic result. **Use a front-facing photo.** Both sides of the mouth visible, even lighting, mouth closed. Side angles and strong shadows will hurt your sync. **Match face to tone.** A deadpan face reading an excited script looks off. Pick a photo whose natural expression matches the energy of your content.

What makes a good source photo for an avatar?

Front-facing, well-lit, and close-up. The cleaner the face in the photo, the cleaner the sync. Avoid heavy shadows, extreme angles, or partially obscured faces.

Can I dub a video into a different language?

Yes. Upload the source video, provide translated audio or a translated script, and the agent generates a synced version with lips matched to the new dialogue.

How do I control the tone and delivery?

Add emotion cues directly in your script — words like 'said firmly' or 'whispered' or 'with excitement' shape how the performance is delivered. Iterate on the first few seconds first before generating the full video.

Can I use the output in paid ads?

Yes. You own full rights to everything you generate. Use it across Meta, TikTok, YouTube, LinkedIn, or any other platform without licensing restrictions.

Can I reuse the same avatar across multiple videos?

Yes. Upload the same photo each time and generate as many scripts as you need. The result is a consistent on-screen presence across every video — without ever filming again.
