Turn business knowledge into presenter-led video
Synthesia centres video creation on a spoken script and an on-screen presenter. Stock avatars offer ready-made presenters, while personal avatars reproduce an authorised person’s likeness. Narration, uploaded media, text and scene layouts can be combined in the editor. This format is useful for onboarding, process explanations and internal updates where a clear spoken message matters more than generating a cinematic shot. The avatar library and custom-avatar allowance depend on the subscription; access to a face does not imply unrestricted advertising rights.
The current Assistant develops a video through conversation inside the editor. A prompt, a final script or supporting documents can provide the starting material. It prepares an outline, scenes and visuals, then allows further revisions without abandoning the project. Avatar Builder supplies another route to a presenter: its prompts and style controls create lifelike, illustrated or non-human characters without accepting photo references. AI Playground produces separate image, video and motion-graphic assets that can be added to a scene. Generation consumes credits, with different costs for different assets.
Publishing options distinguish a regular video from an interactive lesson. Paid non-interactive projects can be downloaded as Full HD MP4 files, with caption and audio exports available separately. Interactive videos retain buttons and branching through sharing or embedding; those interactions cannot be preserved in an ordinary MP4. Pro adds interactive-video features, while Enterprise adds SCORM export, brand kits and team controls. Synthesia also supports dubbing and conversational sessions, each with its own usage rules. For advertising, its stock and synthetic avatars are restricted: custom avatars require an appropriate agreement and informed consent.
Best for
- Learning teams producing training and onboarding videos
- Businesses publishing multilingual explainers and internal updates
- Teams combining presenter videos with interactive learning
Limitations
Basic videos are watermarked and cannot be downloaded as MP4. Interactive projects also cannot be exported as ordinary MP4 without removing their interactive elements. Stock and synthetic avatars are excluded from paid promotion. Credit use depends on generated avatar footage and added assets; a typical finished-minute estimate is not a fixed quota. Monthly allowances expire, and annual credits follow annual billing terms.
