Synthesia

Video Agents are Synthesia's revolutionary new feature enabling two-way, real-time conversations within videos. Unlike traditional static videos, Video Agents can talk, listen, and respond to viewers dynamically, creating truly interactive experiences that adapt based on user input.

Video Agents connect to business knowledge bases including SharePoint, Google Drive, CRM systems, and LMS platforms to operate with full business context. They can automate job screening, conduct interactive training scenarios, provide customer support, and guide learners through complex processes while capturing data for business intelligence.

Availability: Video Agents are currently in development with expected rollout in early 2026 for Enterprise customers.

Express-2 avatars represent a revolutionary advancement in AI avatar technology, moving far beyond static talking-head approaches. These new avatars combine facial expressions and perfect lip sync with natural hand gestures and body language, making them move like professional speakers.

Key improvements include full-body movement with natural hand gestures and pointing, multiple viewing angles (close-ups, medium shots, wide shots), professional presentation style with contextual gestures, and enhanced emotional range based on script content. Express-2 uses a sophisticated three-part architecture trained on thousands of hours of professional speaker footage.

Currently available avatars: Ryan, Ada, Michael, Ellie, and Zola are included across all paid plans at no additional cost.

Express-Voice is Synthesia's proprietary voice cloning model that creates perfect voice clones in seconds while preserving your unique accent, dialect, rhythm, and emotional characteristics. Unlike traditional voice cloning tools that often neutralize accents or impose American/British speech patterns, Express-Voice maintains the nuanced characteristics that make each voice authentic.

The technology requires only a few seconds of audio to create accurate voice clones, maintains regional accents and dialects across 17+ diverse accents tested, preserves natural rhythm and expressiveness, and enables voice cloning across multiple languages while maintaining identity. In blind testing with 100 native English speakers, Express-Voice was rated highest for matching original speaker identity.

This is critical for global organizations that want to maintain cultural authenticity and respect diverse audiences rather than forcing neutral accents.

Synthesia positions itself as a premium platform with pricing that reflects enterprise-grade capabilities. Starting at $29/month ($18/month annually), it's similarly priced to HeyGen but significantly more expensive than D-ID ($5.90/month) or Elai.io ($23/month).

However, Synthesia justifies premium pricing through 230+ professional avatars (vs competitors' 80-150), revolutionary Video Agents with no competitor equivalent, Express-2 full-body avatars with industry-leading realism, enterprise-grade security (SOC 2, GDPR, ISO 42001), and advanced AI integrations including Google Veo 3 and Express-Voice technology.

For organizations requiring scalable, professional-grade video production with cutting-edge capabilities, Synthesia's pricing delivers superior ROI through advanced features unavailable elsewhere. The platform is trusted by 90% of Fortune 100 companies for critical business communications.

Synthesia typically requires 10-15 minutes for video generation, depending on script complexity, chosen avatar, language requirements, and custom elements like backgrounds or overlays. This is slower than competitors like HeyGen (3-5 minutes) or D-ID (5 minutes), but the additional processing time enables higher quality output with more sophisticated avatar movements and voice synthesis.

Factors affecting processing time include video length, number of scenes, Express-2 avatar usage (full-body rendering), custom elements and branding, and multilingual voice synthesis complexity. Enterprise users may receive priority processing for faster turnaround times.

The platform processes videos in the cloud, allowing users to continue working on other projects while videos render in the background queue. Most users find the quality improvements worth the additional processing time for professional business applications.

Synthesia has pioneered AI safety in synthetic media and is on track to achieve ISO/IEC 42001 certification for responsible AI development and use. The platform implements comprehensive safety measures including explicit consent requirements for personal avatar and voice creation, usage restrictions preventing deception or unauthorized impersonation, and automated content moderation detecting inappropriate or harmful content.

Additional safeguards include enterprise customer verification processes, usage monitoring to detect potential misuse, watermarking on generated content indicating AI creation, and GDPR and SOC 2 compliance built into platform architecture. Synthesia also maintains clear ethical guidelines for AI development aligned with industry best practices and provides transparency about AI capabilities and limitations.

This approach balances innovation with responsibility, ensuring powerful AI capabilities remain accessible for legitimate business use while preventing misuse through technical and policy controls.

Veo 3 integration brings Google's most advanced video generation model directly into Synthesia, enabling Enterprise customers to create custom, cinematic-quality visual assets on demand. This eliminates the need to search stock footage libraries and enables creation of bespoke B-roll that perfectly matches specific storytelling needs.

Veo 3 capabilities include text-to-video generation (8-second clips from text prompts), cinematic-quality visuals with professional-grade motion and effects, contextual asset generation matching specific content needs, and seamless embedding of generated assets into Synthesia videos.

Example: An AI avatar delivering safety training can be accompanied by Veo 3-generated footage showing exact machinery and procedures being discussed, creating more engaging and contextually relevant content. Availability is limited to Enterprise customers, consuming 48 credits per 8-second asset.

Yes, Synthesia excels at multilingual video creation with support for 140+ languages and 2000+ natural voices. The platform enables the same avatar to speak multiple languages convincingly, making it ideal for global organizations requiring consistent branding across diverse markets.

Multilingual capabilities include authentic voice synthesis capturing natural pronunciation and intonation, Express-Voice technology preserving accents and dialects across languages, AI Dubbing for frame-accurate translation of existing videos into 30+ languages with perfect lip sync, and one-click translation features on Enterprise plans supporting 80+ languages.

Language support includes major world languages like English, Spanish, French, German, Mandarin, Japanese, Arabic, Hindi, and many others, with continuous expansion based on user demand. This makes Synthesia the leading choice for organizations operating in multiple markets who need to maintain message consistency while respecting local language preferences.
