How to Migrate from HeyGen to Synthesia (Step-by-Step)

Last updated: March 2026

Migrating from HeyGen to Synthesia often makes sense for teams needing more photorealistic avatars (140+ vs. HeyGen's smaller library), broader language support (120+ languages), or enterprise-grade features. While both tools create AI videos without filming equipment, Synthesia offers superior avatar realism, custom avatar creation, and better corporate security features. This guide covers account setup, data migration, workflow adaptation, and team training to ensure a smooth transition. You'll learn how to map HeyGen features to Synthesia equivalents and avoid common migration pitfalls.

Feature Mapping

HeyGen	Synthesia Equivalent	Notes
AI Avatars Library	140+ Photorealistic AI Avatars	Synthesia offers more realistic but sometimes less animated avatars; different art style
Instant Video Translation	120+ Languages and Accents	Synthesia supports more languages but may use different voice actors
Voice Cloning	Custom Voices (Limited Availability)	Synthesia's voice cloning has stricter requirements and limited language support
Script-to-Video Editor	Text-to-Video Editor	Similar functionality but Synthesia uses scene-based editing vs. timeline
Template Library	Video Templates and Scenes	Synthesia offers professional templates but different categorization system
Team Collaboration	Workspace with Team Permissions	Synthesia provides more granular enterprise controls
API Access	Synthesia API	Different endpoints and parameters; requires code adaptation
Free Tier	No Free Tier	Synthesia starts with paid plans only

Data Transfer Guide

Export from HeyGen: Log into your account, navigate to 'My Videos,' select projects, and download MP4 files. Export scripts separately via copy-paste or text export. Screenshot avatar configurations since direct settings transfer isn't possible. For voice clones, note that these cannot be exported—you'll need to recreate them in Synthesia if supported. Import to Synthesia: Upload media files to Synthesia's asset library. Recreate videos by pasting scripts into the text editor, selecting equivalent avatars and voices, then adjusting timing in Synthesia's scene-based interface. Use Synthesia's API for bulk migration if you have programming resources. Expect manual recreation for most content since no direct import tool exists.

Frequently Asked Questions

Can I transfer my data from HeyGen to Synthesia?+

You can export final videos as MP4 files and scripts as text, but project files, avatar configurations, and voice clones cannot be directly transferred. Most content requires manual recreation in Synthesia's different interface.

How long does migration take?+

For a solo user with 10 videos: 2-5 days. Small teams: 1-2 weeks including training. Enterprises: 3-6 weeks due to workflow integration and custom avatar creation. Complexity depends on video count and customization level.

Will I lose any features switching to Synthesia?+

You may lose specific avatar styles or voice options since libraries differ. HeyGen's free tier isn't matched in Synthesia. However, you gain more photorealistic avatars, additional languages, and better enterprise features.

Can I use both tools during migration?+

Yes, run parallel systems for 1-2 weeks. Create new videos in both platforms to compare outputs. Maintain HeyGen subscription until you've successfully recreated all priority content in Synthesia and updated integrations.

Is Synthesia cheaper than HeyGen?+

Synthesia lacks a free tier, so entry cost is higher. For paid plans, Synthesia typically costs more but offers superior avatar realism and enterprise features. Compare specific plan features rather than just pricing.
