Glossary
A video format where one person (or avatar) talks directly to camera — the dominant format for tutorials, sales, courses and social explainers.
Talking-head videos win on conversion because the viewer sees a face, hears a voice, and builds trust faster than with screen-only content. The format is short enough to ship daily and dense enough to carry real information.
AI talking-head generators remove the bottleneck of recording, re-recording, lighting, and editing — you can ship the same script in five languages, by five different presenters, in an hour.
A digital character — usually built from a single photo — whose lips, jaw, and expressions are animated by AI to match a chosen voice or script.
A virtual on-camera spokesperson generated by AI — used for explainer videos, product demos, courses, and internal communications.
Software that creates video from prompts, scripts, images, audio, or existing footage. It may generate one shot or plan and assemble a complete multi-scene video.
