Frequently Asked Questions

Q: How realistic are HeyGen's AI avatars? A: Premium avatars with custom creation are highly realistic with accurate lip sync. Free tier avatars are more basic. Quality improves significantly with paid plans, especially using personal video uploads.

Q: Can I use HeyGen videos commercially? A: Yes, all paid plans include commercial usage rights. Free plan videos include watermarks which may limit commercial applications.

Q: How does the credit system work? A: Credits are consumed based on video generation, with costs varying by video length, avatar type, and features used. The system has been criticized for lack of transparency in consumption rates.

Q: Can HeyGen replace professional video production? A: For certain use cases (explainers, training, simple marketing), yes. For high-end productions requiring complex cinematography, physical product interaction, or emotional nuance, professional production is still recommended.

Q: Is there a learning curve? A: Minimal. Most users create their first video within minutes. Advanced features like custom avatars and multi-scene editing require some familiarization.

Q: What languages work best with HeyGen? A: Major languages (English, Spanish, Mandarin, French, German, Japanese) have excellent voice quality and lip sync. Less common languages may have variable quality—test before committing to large projects.
