HeyGen Avatar IV Storyboard Concept: From Text to Talking Picture
Using a single frontal portrait photo plus a voiceover script, this demonstrates the "text→picture" transformation path of HeyGen Avatar IV: the script drives lip sync and facial expressions via speech synthesis, and the static photo is activated into a talking video with gestures. The piece also fixes non-media parameters such as voice, resolution, and aspect_ratio, making it easy for developers to observe the minimal structure of the submit input and how media fields are bound. It is well suited for prototype validation of digital spokespeople, character narrative shorts, and instructional talking-head videos.

Prompt
A single frontal portrait is turned into a talking video: the person delivers a short storyboard voiceover with natural lip sync, accompanied by slight head movement and expressive gestures, framed in 16:9 with a clean neutral background, a steady medium close-up, soft key lighting, and a calm, confident pace.
