Synthesia: Leading AI Avatar Video Generation Platform

I. Background and Technology

II. Function Introduction

(I) Core AI Functions

1. Avatar Video Generation
   • Avatar Library: It provides more than 140 pre – built avatar images, covering various scenarios such as business, education, and healthcare (e.g., the virtual lecturer “Sam” and the technical expert “Lila”). It supports customizing clothing, hairstyles, and gesture actions.
   • Real – Person Cloning: By uploading a 20 – second real – person video or photo, the AI can generate a 1:1 digital clone, retaining the facial features and speaking style of the real person. This is suitable for scenarios such as corporate executive speeches and internet celebrity IP incubation.
2. Multilingual Intelligent Adaptation
   • It supports text input and speech synthesis in over 120 languages, including non – Latin languages (such as Arabic, Hindi, and Thai), and automatically generates corresponding language subtitles and background text.
   • Users can specify the accent type (e.g., American English, Australian English), and the avatar’s voice can accurately simulate regional pronunciation characteristics.
3. Dynamic Scenes and Material Library
   • The platform has a built – in library of over 100,000 royalty – free video clips, animations, and chart templates. The AI automatically matches scenes according to the text content (for example, a science and technology product demonstration will be matched with a laboratory background, and a financial report will be matched with data visualization charts).
   • It supports uploading corporate VI elements such as logos and standard colors. The AI automatically applies these elements to the video title, subtitle bars, etc., ensuring brand visual consistency.

(II) Advanced Functions

1. Interactive Video Design
   • Interactive elements such as multiple – choice questions and drag – and – drop questions can be embedded in the video. Different user answers can trigger different plot branches, enhancing the engagement of training and marketing content.
2. API Integration and Batch Processing
   • It provides API interfaces for enterprises, enabling the video generation function to be embedded into their own systems (such as CRM and learning management systems LMS). For example, it can automatically generate personalized welcome videos for new users.
   • It supports batch importing of text from Excel to generate multilingual version videos at one time, which is suitable for the global content deployment of multinational enterprises.
3. AI Image Generation
   • Text – to – Image: With powerful GANs technology, it can transform the text descriptions input by users into high – definition images. Whether it is an abstract concept or a specific description of a scene, character, or object, it can be accurately presented. For example, when entering “a sci – fi – style city night view with glowing cars flying in the air”, Synthesia can quickly generate a futuristic image, providing rich materials for creative design and advertising production.
   • Image Customization: It supports adjusting the details of the generated images, such as color style, lighting effect, and element layout. Users can further optimize the generated images according to actual needs to make them fully meet project requirements.
4. Audio Processing Functions
   • Audio Addition and Editing: Users can easily upload local audio files (supporting formats such as mp3, wav, ogg, aac, flac) to the video, and can also select suitable tracks from Synthesia’s vast music library. In the video editor, users can conveniently adjust the audio volume, clip the audio duration, set the audio fade – in and fade – out effects, and precisely synchronize the audio to specific video segments to ensure perfect audio – visual coordination.
   • AI Voice Generation: Using advanced speech synthesis technology, it converts input text into high – quality voiceovers. It offers a variety of timbres, languages, and accents, allowing users to customize exclusive voice effects according to the video style and audience, such as a warm and friendly customer service voice or a professional and serious business explanation voice.
5. Virtual Reality (VR) Content Support (Planning and Development Direction): Synthesia is actively exploring the integration of AI – generated content with VR technology. In the future, it is expected to support the generation of immersive VR video content, such as virtual training scenarios and VR marketing experiences. Through VR devices, users can immerse themselves in the virtual environment generated by Synthesia, achieving a more intuitive and interactive experience, opening up new application possibilities for industries such as education and training, real estate display, and cultural tourism promotion.
