What Synthesia is
Synthesia converts written content into presenter-led video. It is designed for enterprise learning and communications, with the tooling that environment requires: brand templates, controlled avatars, team permissions and localisation.
- Script or document to presenter video.
- Stock avatars and, with consent, custom avatars.
- Brand templates for consistent output across teams.
- Multi-language delivery from one script.
What it is good at
| Use | Fit |
|---|---|
| Compliance and onboarding training | Excellent |
| Internal communications | Excellent |
| Product and process explainers | Strong |
| Multi-language training rollout | Excellent |
| Marketing brand films | Poor |
| Cinematic or product footage | Not applicable |
Buy it for governance: teams choose Synthesia for control and consistency at scale, not because the generation beats a general video model. That is the right reason to choose it.
Structuring content
- Break content into short modules, ideally two to five minutes.
- One idea per module. Training video fails when it tries to cover too much.
- Write in spoken language — short sentences, plain words.
- Plan on-screen text and visuals separately from the narration.
- Build in a check point where the learner does something.
Avatars and brand consistency
-
Choose avatars deliberately
Match the avatar to audience and subject matter; consistency matters in a training series.
-
Set up brand templates early
Colours, fonts and logo placement applied once save rework across every module.
-
Limit who can change templates
Brand drift across teams is the most common failure at scale.
-
Get consent for any custom avatar
Written, naming the specific use, plus separate voice clearance.
Producing a module
-
Draft the script and read it aloud
This catches unwieldy phrasing before you generate anything.
-
Generate one section and review
Check voice, pacing and pronunciation before committing to the full module.
-
Add visuals and on-screen text
Support the narration rather than repeating it verbatim.
-
Review with a subject matter expert
Accuracy matters more than production polish in training.
-
Publish and gather completion data
Training video is only useful if you know it was watched and understood.
Localisation
- Keep one source script as the single point of truth, so versions do not diverge.
- Have translations reviewed by a speaker of the language, especially for technical terms.
- Adjust timing — translations that run long cause rushed delivery.
- Keep original audio available for viewers who prefer it.
Governance considerations
- Define who may create avatars and of whom, with consent records attached.
- Set retention rules for custom avatars when people leave the organisation.
- Disclose synthetic presenters where required for your sector and markets.
- Keep an audit trail of who published what and when.
