AI Dubbing translates and dubs existing videos into 140+ languages with lip-sync that matches the new audio precisely.

One master video becomes localized across global markets without re-recording. This feature eliminates the weeks-long localization cycles that traditional video production requires.

Scene Customization

Scene customization powered by Veo 3 AI allows you to prompt specific outfits, backgrounds, and on-screen actions in natural language without manual editing.

You can describe industry-specific clothing (uniforms, hard hats, safety glasses, lanyards) or branded outfits featuring your company colors and logos. The AI generates the scene with the avatar performing your described actions.

Branding and Consistency

Brand Kit feature automatically applies your company colors, fonts, logos, and preferred avatars across every video in your library.

This eliminates manual formatting and ensures consistent visual identity at scale without design knowledge.

Smart Updates mean that embedded videos or shared links automatically refresh with your latest edits. No need to re-upload, re-distribute, or send new links when you revise content.

Video Engagement and Analytics

Interactive Avatars (beta) build avatars that listen, talk, and respond in real-time conversations. Deploy them across sales, customer support, training, and onboarding to create dynamic, conversational videos. Connect your own LLM or agent while Synthesia powers the avatar layer.

Video Agents (coming soon) will further automate video strategy, content creation, and publishing workflows.

Analytics dashboard tracks views, watch time, completion rates, and audience engagement metrics per video.

Identify which content performs best and where viewers disengage to guide rapid iteration and content optimization.

An independent peer-reviewed study at USC Marshall tested AI avatar videos against human presenters across 250+ professionals and found identical knowledge transfer across both groups.

This evidence supports ROI conversations with skeptical stakeholders. Global localization into 160+ languages without re-recording means one video strategy scales to all markets automatically.

In Synthesia’s 2026 AI in L&D Report, 54% of respondents said global localization is where they expect AI to deliver the most value.

The free plan is genuinely useful for testing without a credit card or commitment. First-time users create their first avatar video in under an hour.

What Synthesia Does Not Offer

Synthesia does not offer SCORM export for learning management systems. Videos must be embedded or linked within LMS platforms rather than packaged as SCORM-compliant courses.
