How long can an Avatar video be?

Supported models and plans allow up to five minutes; the current quote and entitlement shown in the product are authoritative.

How many people can lip-sync in one scene?

Multi-person mode supports up to ten people with a correctly mapped audio track for each role.

Can I revoice and lip-sync existing footage?

Yes. SekoTalk V3 accepts character video and uses video frames as anchors for a new lip-sync pass.

Can I clone anyone's voice?

No. Only use voices and media you are authorized to use, and never impersonate or mislead.

Can one photo create an Avatar?

Yes. Use a clear, evenly lit portrait with an unobstructed mouth and complete head framing.

Can I use my own voice?

Yes. Upload authorized audio, use AI speech, or create a cloned voice from media you have permission to use.

Which languages are supported?

Language availability depends on the selected voice and model; follow the current voice details in the workspace.

Why can lip sync look unnatural?

Mouth occlusion, extreme profiles, noise, fast speech, rapid edits, or overlapping people can reduce stability.

What media should I avoid?

Avoid blurred, heavily compressed, obstructed, or rapidly cut media where faces and mouths are difficult to follow.

Can Avatar videos be used commercially?

Commercial use depends on media, likeness, voice, model, and plan rights. Confirm all required permissions before publishing.

LightX2V Studio

AI Avatar Generator

Create natural talking Avatar videos from images, video, text, or speech, with existing-video and multi-person lip sync, 600+ voices, voice cloning, and multilingual production.

What Avatar videos can you create?

Create a talking Avatar from one photo, lip-sync existing footage while preserving motion, or produce long-form and multi-person dialogue with role-specific tracks.

Create an Avatar in three steps

Upload a portrait or video, create or upload authorized speech, then choose a single- or multi-person model to generate and review the result.

Image Avatar versus video lip sync

Image Avatar is efficient for standard presentations. Video lip sync preserves source performance and camera motion for new copy, voice, or language.

Media requirements and responsible use

Use clear, unobstructed faces and clean audio. Confirm likeness, voice, and commercial rights before publishing synthetic media.
