HeyGen Video 1
by HeyGen
HeyGen's general-purpose video generation model for short-form business video.

Built for brand moments, product and equipment demos, and training or onboarding content. Unlike Avatar IV there is no talking-head or lip-sync step; the prompt and references drive the whole scene.
