Description

HeyGen Avatar4 — turn a portrait image into a talking avatar video with audio or prompt+voice

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.
