"How to Create AI Avatar Videos in 2026"
AI avatars let you produce a talking-head video without a camera, crew, or studio. In 2026 the output is convincing enough for training, explainers, and social.
The two leaders
- HeyGen — photo-real avatars, instant translation into many languages while keeping your lip-sync, and a “avatar in a window” mode for slides.
- Synthesia — the enterprise training standard with 140+ avatars and strong governance for compliance video.
Step 1: Write the script
Avatars read a script — write tight, spoken-language copy. Long run-on sentences read poorly.
Step 2: Pick or make an avatar
Use a stock avatar, or create a custom one from a short video of yourself (consent and rights matter for commercial use).
Step 3: Generate and localize
Render in minutes. Both tools dub the same avatar into dozens of languages with synced lips — a huge win for global training.
Step 4: Composite
Drop the avatar over slides or product footage. Runway can generate B-roll to cut between talking heads.
