Integrating Synthesia: AI Avatars for Corporate Video
We regularly see the same pain: a company spends weeks shooting and editing training videos, and a month later the policy changes — and the process repeats. Synthesia breaks this cycle. Just edit the script, and in a few minutes the platform regenerates the video with the same avatar, tone, and background. We set up the full pipeline: from API to final delivery in an LMS with SCORM support. With automation, production time drops by 90%, and localization costs fall by 80%.
Why Synthesia Is Worth Integrating
Ready-made avatars: 230+, languages: 140+. The platform is certified under ISO 27001 and SOC 2, data stays with you. Fortune 500 companies already use Synthesia for onboarding and compliance training. The key advantage is speed: a 3-minute video generates in 3–8 minutes. That’s 50 times faster than traditional shooting. Official documentation confirms these numbers.
What Problems We Solve
The first is lack of a unified pipeline. The training department assembles content from PowerPoint, speaker videos, subtitles — all manually. Synthesia API automates content import and whole course generation.
The second is localization. Previously, each language required a separate shoot. Now just translate the script and run generation. We integrate machine translation (DeepL, Google Translate) for preprocessing.
The third is personalization. Using CRM data (name, company, job title), we generate a unique script for each employee. The avatar speaks the text with personalized inserts — this boosts engagement by 30%.
How the Integration with LMS Works
A typical scenario: your LMS sends a request via webhook when a new employee is enrolled. A backend service receives the data, plugs it into a script template (JSON), sends a request to Synthesia API. The finished video is uploaded back to the LMS via a SCORM package or direct link. We use PyTorch for media processing and FFmpeg for post-processing.
Example template configuration:
{
"avatar": "anna-01",
"script": "Hello, {{name}}! Your onboarding starts today.",
"language": "ru",
"format": "mp4",
"background": "company_office"
}
Error handling: if generation fails (e.g., token limit exceeded), we retry with exponential backoff. Synthesia rate limit is 10 requests per minute, so we use a queue (RabbitMQ or Redis).
Comparison: Synthesia vs Traditional Shooting
| Criterion | Synthesia Integration | Traditional Shooting |
|---|---|---|
| Time to create 3-min video | 3–8 minutes | 3–5 days |
| Content update | Edit script | Full reshoot |
| Localization | 140+ languages automatically | Separate shoot per language |
| Scaling | API, batch processing | Linear (more actors needed) |
| Personalization | Yes, via CRM | No or limited |
Process and Scope of Work
| Phase | What We Do | Timeline |
|---|---|---|
| Analytics | Audit current content, select automation scenarios | 1–2 days |
| Design | Architecture of integration, workflow, choose LMS endpoints | 2–3 days |
| Implementation | API setup, middleware development, script templates | 3–5 days |
| Testing | Pilot on 3 scenarios, quality check | 2–3 days |
| Deployment | Connect to production LMS, monitoring, team training | 1–2 days |
| Support | Maintenance for one month | optional |
What’s Included in the Integration
- Synthesia API and webhook configuration.
- Middleware service development (Python/FastAPI).
- LMS integration (SCORM/xAPI).
- Script template preparation.
- Documentation and admin training.
- First month support.
Estimated Timelines
From 1 to 3 weeks depending on the number of scenarios and LMS complexity. The cost is calculated individually — we assess the project within one day after an initial call. Get a consultation — we’ll tell you how much you can save on video production.
Typical Integration Mistakes
- Ignoring rate limits (Synthesia API — 10 requests per minute).
- Not handling generation errors (failed videos must be regenerated, not lost).
- Incorrect script formatting (Synthesia requires strict JSON).
- Forgetting access rights: avatars and templates must be tied to the API key.
