Custom Digital-Human Videos:One Photo and a Script Are Enough

Many organizations want a digital human to explain policies, products or history—then find the template avatars all look alike, the lips don’t match the words, the voice sounds robotic, and the face changes from scene to scene. Not good enough for anything official.

We build the character from scratch for you: a digital twin of a real staff member, a fictional presenter or a historical figure. You send photos or a brief plus the script; we generate it with the latest models, match voice and lip-sync, and deliver a subtitled film.

01CHALLENGES

Where this kind of video usually gets stuck

01

Template faces everywhere

Stock avatars are available to everyone; the same face shows up in other people’s videos, so nobody remembers it as yours.

02

Unnatural lips and voice

Mouth movements drift from the words and the voice sounds flat, which looks careless at a formal event.

03

The face shifts between scenes

The same presenter looks different in the studio, outdoors and in the hall—especially obvious across a series.

02WHY AI

How AI solves them

A character that’s yours

Face, hair, outfit and manner are designed for you—or generated from a real person’s photos with their consent—so no one else has it.

Voice and lip-sync tuned

We pick a voice by age, gender and tone, or use an authorized real voice, and align lips and pauses line by line.

Any setting you need

Your digital human can present from your lobby, workshop or scenic spot, rebuilt from photos—no studio set.

One character, a series

Once the character is set, every episode reuses it with the same face, clothes and voice.

03WHAT WE MAKE

What we can make

01

Policy and service explainers

A presenter walks through a new policy or procedure, with charts and on-screen steps.

02

Brand spokesperson and product intros

Your own spokesperson character introduces new products, the same face for every holiday and launch.

03

Historical figures who speak

Figures rebuilt from historical sources read their letters and tell their own stories.

04

Multilingual versions

The same content in Chinese and English, lip-synced to each language for overseas audiences.

04HOW IT WORKS

How it works

Each step comes to you for approval before we move on.

  1. STEP 01

    You share the brief

    Tell us who presents, to whom and where it plays, plus photos or references for the look and a script or key points.

  2. STEP 02

    We set the look and voice

    We show several character stills and voice samples; you choose one, and we keep refining until it’s right.

  3. STEP 03

    We generate and sync

    We generate the presenter speaking your script, add backgrounds, subtitles and graphics, and cut a first draft.

  4. STEP 04

    Final delivery and more episodes

    We deliver landscape and vertical cuts; for each new episode, just send the next script.

07FAQ

Frequently asked questions

What do I need to prepare?
For a real person’s twin, a few clear front and half-body photos, with their consent; for a fictional character, a description or reference images. Plus a script or key points.
Can the digital human speak English?
Yes. Chinese and English are both supported, with lip-sync done separately for each; for other languages, message us on WeChat.
How long does a film take?
The first time we set the character takes a bit longer; a 1–2 minute film usually reaches first cut in about a week. Later episodes go faster. Rush production is available; timeline and price are agreed case by case.
