1. Introduction to Synthesia
Synthesia is the global leader in generative AI video creation, enabling companies to produce professional-grade videos from text in minutes. Traditionally, video production is a costly and slow process involving cameras, microphones, actors, studios, and long editing cycles. Synthesia eliminates this friction by utilizing advanced deep learning to generate photorealistic AI avatars and natural-sounding voiceovers. Users can select from a library of over 150 diverse avatars (modeled after real actors), type their script in more than 120 languages, and instantly generate a high-definition video. The avatars display natural facial expressions, head movements, and perfect lip-syncing. Combined with tools for adding slide layouts, media files, and transitions, Synthesia is the premier choice for organizations seeking to scale corporate training, customer support, sales enablement, and product documentation videos.
2. Who is Synthesia for?
Synthesia is built for corporate trainers, customer success managers, product marketing teams, human resource departments, and online educators. It is exceptionally valuable for global enterprises that need to produce and translate localized training videos in multiple languages. Customer support teams use Synthesia to create short product explainer videos to resolve help tickets. L&D (Learning and Development) professionals leverage it to convert boring, text-heavy PDFs and manuals into engaging video presentations.

5. How does Synthesia work?
Synthesia works using advanced computer vision and voice synthesis neural networks. First, real actors are recorded in a studio under various lighting conditions. Synthesia's proprietary models analyze their facial micro-movements, lip movements, and gestures to create a digital avatar. When a user inputs a script, the text-to-speech engine generates the audio voiceover, while the video generation engine synthesizes the avatar's lip-syncing and facial expressions to match the spoken words. The resulting video frames are rendered in high-definition alongside your slides, text overlays, and backgrounds.
