Migrate from synthesia to heygen.
1 documentation-derived translation pattern — what carries over and what to watch for. Cited to the Feature Parity Map; the audit tells you whether the move is worth it.
Both tools turn a written script into an MP4 of a talking AI avatar, so move the workflow by recreating your script in HeyGen's web AI Studio: pick a stock Public Avatar (or a template), paste the script, choose a voice, and render. To approximate Synthesia's document-to-video drafting, build the deck content into HeyGen scene-by-scene, since the script still drives delivery, tone, and gestures. Match your old Synthesia output tier to a HeyGen plan by video length and resolution — Creator/Pro reach up to 30 minutes (1080p/4K), Business up to 60 minutes at 4K — and download the MP4 as before.
- Warning: Synthesia's editor is scene/storyboard-based with built-in PowerPoint/PDF/Word/URL-to-video drafting and LMS/SCORM export aimed at training content; HeyGen is script-driven in AI Studio and does not target SCORM/LMS packaging, so course-export workflows do not carry over. Also re-check avatar/voice coverage: the available avatar libraries and language/voice sets differ between the two, so a specific Synthesia avatar or voice may have no exact HeyGen match.
