HeyGen vs Synthesia

• Translating existing videos for audiences in other languages
• Teams producing training content with SCORM export on the Business plan

Synthesia

• Training and L&D teams producing videos without filming

HeyGen

• The Free plan allows 3 videos a month of up to 1 minute each; watermark removal and 1080p export start on Creator.
• Paid plans are metered in credits, and the number a video uses varies with the AI model, its duration and its complexity.
• SAML/SSO, SCORM export, LMS integrations and workspace collaboration are listed from Business at $149 a month, plus $20 per extra seat.
• Unused credits roll over for one month on monthly billing and are lost when a subscription is cancelled.

Synthesia

• Basic videos carry a Synthesia watermark; downloading videos and removing the logo start on the Starter plan.
• Usage is metered in credits: video costs about 100 credits a minute, so Starter's 1,250 monthly credits add roughly 12 minutes.
• Self-serve plans include 1 editor; Starter adds 3 guests and Pro 5, and guests are invited to comment on videos.
• SAML/SSO, live team collaboration, SCORM export and 1-click translation are listed under the Enterprise plan.
