Category: video

Description

HeyGen Avatar (Digital Twin) — generate a talking-avatar video from a script or an audio track. Both versions pick the avatar from HeyGen's stock catalog. A custom (cloned) voice ID works on Avatar IV only.

Pricing

• Cost: ~16 credits per seconds
• Per-second rate: The figure is the rate at a 5-second reference run. Our margin is progressive and steepest on the smallest runs, so a clip shorter than that can cost more per second, and a model priced with a flat multiplier is exact at every length. The charge is always computed from the real duration.
