LIGHTX2V / AI AVATAR
AI Avatar Generator
LightX2V Studio turns a portrait or existing footage into a talking video. Built on the LightX2V video generation inference framework, it can generate speech from a script or use audio you have permission to use. Create photo avatars, lip-sync existing videos, or produce multi-person conversations for explainers, course introductions, and product presentations.

Make multiple people in one frame speak in scripted turns.
- Input
- Two-person image + role-specific tracks
- Model
- SekoTalk V3 Multi
- Output length
- about 49 sec
Overlapping people, frequent occlusion, or incorrect track mapping can affect results.
Read the guide ↗Lengths above describe output videos. Waiting time varies with inputs, model, and queue; the two-person sample does not demonstrate ten-person output.
02 / CHOOSE
Which approach fits your video?
| Mode | Inputs | Use cases | Requirements |
|---|---|---|---|
| Photo avatar | Portrait + speech | Explainers, course intros, and presenter videos | Motion is generated; use a clear face with an unobstructed mouth. |
| Existing-video lip sync | Footage + new speech | Update speech or language while retaining the source performance | Limit occlusion, extreme profiles, and rapid cuts; check audio pacing. |
| Multi-person dialogue | Shared scene + individual role tracks | Podcasts, interviews, and scripted conversations | Keep faces distinguishable; avoid overlap and incorrect role mapping. |
03 / USE CASES
When is a talking avatar a good fit?
For scripted, presenter-led content. Test complex acting, occlusion, or fast action with a short sample first.
Explainers and course introductions
Portrait + reviewed script
Create clear speech, then a single-presenter video. Review terminology, pauses, and lip sync before delivery.
Read the guide ↗Product presentations
Authorized character media + verified product facts
Turn confirmed product details into spoken copy. Check names, numbers, and promises against the source facts.
Read the guide ↗Rewording or localizing footage
Source character video + new speech
Use existing-video lip sync and review shot continuity, pacing, and proper names. Language support depends on the voice.
Read the guide ↗Two-person scripted interviews
Shared character scene + separate role tracks
Confirm speaker order and role mapping, then review overlap, occlusion, and audio-video synchronization.
Read the guide ↗04 / CREATE
Create a talking Avatar video in three steps
Choose character media and a speech source, then generate. Validate the character, voice, and lip sync with a short sample before producing long-form output.
- 01
Prepare character media
Upload a portrait or existing character video.
- 02
Add the speech
Enter a script for AI speech or upload authorized audio.
- 03
Generate and review
Choose a single- or multi-person model, generate, preview, and download.
05 / COSTS
Understand costs and limits before you start
- Task pricing
- Avatar tasks consume credits based on the model, resolution, duration, settings, and web or API channel. Check the live quote before submitting.
- Speech and membership
- Check entitlements and credit usage for AI speech, voice cloning, and other processing steps as well. Membership and credit balance are separate requirements; purchasing credits does not unlock every member feature.
- Settlement and expiry
- Unsuccessful generation tasks currently have no final task-credit deduction; this is separate from a membership or top-up refund. Trial credits, expiry, duration limits, and model access depend on the current account and plan.
Five checks before production
Long-form production guide ↗Character media
Use a clear face without mouth occlusion or extreme profiles.
Audio quality
Review the full audio for noise, pronunciation, pauses, and length.
Role mapping
Match every person to the correct independent audio track.
Long-form testing
Test a short sample and check model and plan duration limits.
Publishing rights
Confirm commercial rights for likeness, voice, media, and model.
06 / CONNECT
Connect voices, characters, and workflows in one platform
LightX2V Studio connects image, speech, and video capabilities: prepare a character and script, create speech and a talking video, then organize a reusable creative workflow with Agent or Canvas.
01
600+ voices and reusable voice identity
Choose from 600+ AI voices or create a cloned voice from authorized audio or video. Single- and multi-segment speech supports voice instructions and available emotion, speed, loudness, and pitch controls; presets preserve voice and delivery settings.
Explore the workflow ↗02
Extract and rewrite speech from existing video
Upload existing footage to Agent or Canvas, extract spoken copy with ASR, and rewrite it for a new audience, language, duration, or delivery goal. The revised script can continue into speech and Avatar generation without starting over.
Explore the workflow ↗03
Change the scene while preserving character identity
Use text-to-image and image-to-image models to create a character or change clothing, composition, and background while constraining identity with references. Use the resulting character media in new Avatar scenes.
Explore the workflow ↗04
Save the method and produce repeatedly
Once script preparation, voice, character media, Avatar settings, and post-processing form a reliable method, save it as a Canvas workflow or Agent Skill. Teams can repeat the standard and extend it into batch systems through the API.

Questions about talking avatars
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?
Supported multi-person models allow up to ten roles with separately mapped audio tracks. The example on this page has two people; results depend on face clarity, occlusion, and audio quality.
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.
What happens when a task fails?
Unsuccessful generation tasks currently have no final task-credit deduction; this is separate from a membership or top-up refund. Trial credits, expiry, duration limits, and model access depend on the current account and plan.
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 AI or cloned 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.
Can Avatar videos be used commercially?
Commercial use depends on media, likeness, voice, model, and plan rights. Confirm all required permissions before publishing.
How much does a one-minute avatar video cost?
There is no single price across all models and plans. Choose a model, resolution, and duration, then check the credit quote before submission. Account for additional steps such as AI speech, and consult the pricing page for membership and credit prices.
Is LightX2V Studio only for avatar videos?
LightX2V Studio is an online AI avatar and multimodal content production platform built on the LightX2V video generation inference framework. It focuses on avatar video creation, combines video, image, and audio capabilities, and supports reusable creative workflows. Avatars are one core capability. You can also generate images, other types of video, and speech, and organize or reuse creative processes with Agent and Canvas.
Should I use a photo avatar or existing-video lip sync?
Start with a photo avatar for standard explainers when you have a portrait. Choose existing-video lip sync to retain source movement and camera work while changing speech. Multi-person dialogue requires separate role tracks. Test your media with a short sample before producing the final video.
READY WHEN YOU ARE
Start with a portrait and something to say.
Make a short sample first. Check the face, voice, and lip sync, then build your series.
