# Lip-Sync Personalization at Scale

Say a different thing to every viewer, on camera. One recording becomes thousands of renders where the speaker actually pronounces each person's name, company, or offer — mouth movement included.

Capabilities

## What Lip-Sync Personalization does

### Personalized spoken lines

Names, companies, offers, and locations are spoken by the on-screen presenter, not overlaid as text.

### Sync per render

Mouth movement is regenerated for each variant, so a personalized line never looks pasted onto the original take.

### Batch generation

Drive it from a spreadsheet, a CRM, or an API call. Every row becomes its own synced render.

### Multilingual variants

Personalize the language along with the details, so each recipient gets both.

### Pronunciation control

Unusual names stay correct through pronunciation rules and per-provider dictionaries.

How it works

## Four steps, one orchestrated run

Every stage runs on the same platform, so nothing is exported, re-uploaded, or handed between tools.

- 01

### Record once

Shoot or generate a base video with the presenter delivering the fixed part of the script.
- 02

### Mark the variables

Identify the spoken segments that change per recipient.
- 03

### Connect the data

Attach a sheet, CRM segment, or API payload. Each row drives one render.
- 04

### Generate and deliver

Audio and lip-sync are regenerated per variant, then delivered through your channel of choice.

Who it is for

## Teams using Lip-Sync Personalization

### Outbound sales

A presenter who names the prospect's company in the first five seconds.

### Onboarding

Greet every new customer by name, in their language, on camera.

### Events and invitations

Personal invitations at a scale no production team could hand-cut.

### Renewals and win-back

Reference the account's actual usage in a spoken, on-camera message.

FAQ

## Questions people ask

How is this different from standard lip-sync?
+

Standard lip-sync aligns one video to one audio track. Personalization generates a different audio track and a different sync for every recipient, from a single base recording.

Will unusual names be pronounced correctly?
+

Pronunciation rules and per-provider dictionaries let you correct names, brands, and acronyms once, and every subsequent render respects the correction.

How do I trigger renders?
+

From a spreadsheet upload, a connected CRM or ESP, or a direct API, MCP, or webhook call inside your own automation.
