Synthesia

What is Synthesia?

Synthesia is an AI video platform built primarily for scripted business communication. A user selects or creates an avatar, enters a script, chooses voice and language options, combines the presentation with layouts or screen material, and exports a presenter-led video. Teams can reuse templates, collaborate, localize versions, and manage production at a scale that would be slow with repeated studio recording.

The strongest use cases are training, onboarding, internal communication, product explanation, sales enablement, and standardized learning content. Synthesia is not a cinematic text-to-video generator and should not be evaluated as one. Its value is repeatability: changing a sentence, updating a policy, or creating another language version without reshooting a presenter.

A practical avatar-video workflow

Start with a script written for speech. Use short sentences, one idea per scene, visible signposting, and pronunciation notes for names, acronyms, or technical terms. Select an avatar and voice appropriate to the audience rather than treating realism as the only criterion. Add slides, screenshots, captions, and on-screen emphasis where the learner needs evidence beyond a talking head.

Create a one-minute pilot in the exact target language. Review pronunciation, pacing, gestures, eye line, lip sync, caption accuracy, layout, and accessibility. Then ask a subject-matter owner and a native speaker to review the result. A smooth avatar does not make an incorrect script safe to publish.

Templates can reduce brand drift, but governance matters. Lock approved fonts, colors, logo placement, intro and outro, subtitle style, and safe margins. Define who can create an avatar, who can approve a voice or translation, and who can publish. Keep source scripts and version history so regulated or policy content can be audited.

Pricing and capacity planning

The current Synthesia pricing page lists a free Basic option alongside paid and enterprise plans. Credits, seats, avatars, localization, interactive features, collaboration, and API access can differ. Promotions and allowances change, so avoid relying on a price captured in an old comparison.

Estimate output by finished minutes and language versions. A five-minute lesson localized into eight languages is not one five-minute project for budgeting purposes. Include script revisions, pronunciation fixes, alternative takes, stakeholder review, and required seats. Confirm whether credits reset, what happens when a subscription ends, and how long exported and editable project assets remain available.

The customer terms explain that avatars are used through the service rather than exported as independent models. Organizations should plan for vendor dependency: retain scripts, media, subtitles, exported masters, consent documentation, and a method to recreate critical training if the account changes.

Consent and stock-avatar restrictions

Avatar consent is a core requirement, not an optional courtesy. A custom avatar represents a real person and may be paired with new speech in multiple languages. The customer must have the authority to create and use it. Internal consent should specify the company, purposes, channels, geography, duration, withdrawal process, and whether the avatar may be used after the person's role changes.

Synthesia's acceptable-use policy and platform-integrity guidance also distinguish stock and custom avatars. The current guidance prohibits stock avatars in certain paid or promoted social ads, television broadcasts, and NFT use. Do not assume a stock presenter is a universal spokesperson license. Verify the exact channel before a campaign is approved.

The user remains responsible for script claims, uploaded footage, logos, music, trademarks, and disclosure obligations. Synthetic presenters can make a claim feel authoritative, so fact-check product, health, financial, legal, and compliance statements with particular care.

Privacy and organizational fit

Business videos can include employee names, customer data, internal interfaces, and confidential processes. Review the applicable customer agreement, data processing terms, retention, subprocessors, regional hosting, security controls, and model-improvement language. Consumer or free use may not provide the safeguards required by an enterprise policy.

Synthesia is strongest when an organization treats it as a governed content system. A small center of excellence can maintain templates, consent, pronunciation dictionaries, localization standards, accessibility checks, and publishing approval while distributed teams contribute scripts.

Alternatives

Compare HeyGen for digital twins, avatar video, and translation workflows with a different product emphasis. InVideo AI is better suited when the goal is a narrated video assembled from script, generated media, and stock rather than a consistent presenter. VEED AI and Descript offer broader editing when the project starts with recorded footage.

A governed pilot

Produce one short training module in several required languages with documented presenter consent. Have fluent reviewers check pronunciation, names, numbers, tone, captions, claims, and accessibility. Record finished minutes, corrections, stakeholder review, plan use, and total cost. Then test revoking a contributor, withdrawing an avatar, exporting source materials, and recreating the module from retained scripts and media. The result should prove both production efficiency and organizational control.
