HeyGen solves explainers that would otherwise need someone on camera repeatedly: choose a digital presenter or build one from your own footage, add a script and get a talking video; existing speech can be translated and lip-synced. Consent matters most: cloning a real person's likeness or voice requires their agreement and records, and using someone else's image in promotion risks portrait rights; the platform verifies. Expression and gesture still look mechanical, so split long monologues.
What it does
- Scripts become presenter videos with selectable looks and voices
- Custom presenters built from your own recorded footage
- Language replacement and lip sync for existing videos
- Horizontal and vertical scenes and templates
- Bulk personalized generation for teams
Who it is for
- Product explainers need a face talking continuously without repeated filming
- One video needs several language versions
- Internal notices and training need a stable presenter over time
- Existing speech footage needs a new language or background
How to get started
- Try one clip with a stock presenter to check pace and lip sync
- Record your own material as prompted and keep consent records
- Split the script into short sentences, generate in parts, then join in an editor
